Early on, Alza created an oestradiol patch intended to yield a constant flux of oestradiol over 4 days, in which the reservoir contained oestradiol in an ethanolic solution. However, an unexpected oestradiol plasma concentration—time profile was found when the transdermal system was applied to human skin. On day 2, there were higher than expected blood levels, most probably as a result of the back diffusion of moisture from the skin into the patch reservoir reducing the solubility of oestradiol in the reservoir and greatly increasing its thermodynamic activity leading ultimately to the formation of a supersaturated solution and marked skin penetration.
However, on day 3, the blood levels significantly fell as the thermodynamic activity of oestradiol in the reservoir solution was reduced by the formation of oestradiol hemihydrates and their crystallizing out of solution. Hence, the system, and not the skin, controls the entry of drug into the systemic circulation.
However, more important than what is lost from the site of application, as used in these calculations, is the actual systemic plasma nitroglycerin concentration arising from the transdermal products — as these are more reflective of the likely pharmacodynamic effects for the products. Importantly, the variability in the extent of absorption, as defined by SD. The variability in maximum-tolerated doses of nitroglycerin after i.
A key technology advancement implemented to enable efficacious delivery of certain drugs is the inclusion of a skin penetration enhancer. The most important consideration is the maximal delivery rate through the skin. This is evident in the delivery area for the Mylan matrix fentanyl patches, which came onto the market in the early s, being only slightly smaller than Duragesic patch.
Several of Alza's early competitors — Key Pharmaceuticals, Theratech, Cygnus, Noven and LTS — used the matrix concept for nitroglycerin, oestradiol and testosterone to overcome the intellectual property challenges associated with Alza's technology in the s. This market position was achieved because they were not only generally thinner and more flexible and so more comfortable and adhering, but they were also less expensive to manufacture.
Evolution of commercial topical and transdermal patches — transdermal reservoir: originator, generic; transdermal matrix: originator, generic; transdermal active in adhesive only: originator, generic; topical patches; transdermal next generation; topical next generation.
Patches in which drug is mainly incorporated in a polymeric or viscous adhesive DIA , and discussed later, are also matrix patches. In principle, when a drug is suspended in an internal polymer matrix, in the pouch of a form-fill-seal system or in the adhesive of a patch without a distinct internal reservoir, the delivery can be steady zero-order , depending upon just how any such system is designed.
The thermodynamic activity of fentanyl is therefore virtually constant over the whole time the Mylan patch is worn. This design, which, in principle, is also a matrix patch, constitutes the simplest, state-of-the-art transdermal patch design. It has been suggested that the concept of a DIA patch came from the concept of the bubble jet printer where the ink was printed on the surface of some appropriate materials. It was realized that the DIA could be loaded onto the patch backing in the same way G.
Cleary, pers. The effect of various adhesive formulations on transdermal delivery of fentanyl was investigated. Various PSAs acrylate, silicone, silicone and PIB were characterized with respect to fentanyl's solubility, partition coefficient and diffusion coefficient.
The fentanyl release profiles from these adhesives and the in vitro flux through human cadaver membranes were also evaluated. Thus, this adhesive appeared to be a promising candidate to design a transdermal patch for the delivery of fentanyl at a therapeutic rate. Interestingly, even though the acrylate adhesive exhibited a relatively higher release rate in water in these studies, its skin flux was considerably lower compared with the silicone and PIB adhesive formulations.
This was seemingly because the acrylate adhesive was a good solvent for fentanyl and the systems in which this adhesive was used were of lower thermodynamic activity relative to the other adhesives. However, a major disadvantage associated with these patches is that, if the drug is completely in solution, the rate of drug release from the device is dependent upon the drug concentration in the adhesive first-order kinetics , thus bringing about a decrease in the release rate with wear time Levin and Maibach, The early nitroglycerin matrix patches were based upon a high residual content of drug in the patch.
Alternatively, like the membrane control for the reservoir patch, the matrix could also provide some resistance to the penetration of drug into the skin, leading to a lower required drug content in the patch.
In conclusion, the design of all transdermal patches is characterized by a multi-layered structure with most frequently three or four basic elements: an impermeable backing film, a preparation containing the drug s together with the excipient s , an adhesive responsible for skin adhesion and a protective release liner that is peeled off before applying the patch to the skin.
Not all drugs are suitable for patch delivery. The only drugs that can be used are those that can penetrate the skin, that are sufficiently potent to be active and that meet a clinical need. To date, nearly two dozen molecules have been approved by the regulatory authorities for transdermal administration and have reached the market. In turn, solubility can be related to melting point MP , and drug—stratum corneum interactions and diffusivity can be related to molecular weight MW or molar volume Roberts and Cross, They then defined the predicted to actual flux ratios for all marketed drugs.
As the average ratio is 5. Wiedersberg and Guy suggested that higher than expected ratios may arise when penetration enhancers were present in patches, whereas lower ratios arise when the drug concentrations in patches were below saturation. The equation underpinning this nomogram assumes a two-pathway polar and lipid model for drug transport through the stratum corneum Berner and Cooper, Physicochemical, pharmacokinetic and safety data for currently marketed transdermal drugs.
An alternative approach to predicting individual skin penetration fluxes for candidate drugs to be used in patches is to define the physicochemical boundaries within which all candidates in the patch systems should fall. Implicitly, an upper skin limit is also defined by the risk of local skin reactions. The second requirement of drugs in a patch is that they are sufficiently potent to be active. Accordingly, assuming a complete skin bioavailability and a maximum flux of 0.
Accordingly, fentanyl is now widely used in transdermal delivery to manage post-operative pain. The third driver for transdermal patch systems is a cost-effective safety advantage they may provide over other dosage forms for specific drugs. As discussed earlier, patches have less variability than arbitrarily applied solutions, creams and ointments. The ratio of this value divided by the in vivo patch flux gives a safety ratio for a given transdermal patch and is generally 10— An exception based upon Watkinson's data appears to be scopolamine hyoscine.
As Dorne and Renwick pointed out, there should be at least a fold safety factor to allow for human variability. Drugs such as oestradiol, nitroglycerin, oxybutynin, scopolamine, selegiline and testosterone may be unsuitable for p. As Wiedersberg and Guy pointed out, only i. Typical active plasma concentration profile after patch application showing the lag-time, reaching and achieving steady-state, depletion and patch removal as well as the corresponding profile for repeated p.
Given that paracetamol is well absorbed and is readily available in various p. However, the dose for its antithrombotic effect is about an order of magnitude lower than that of its anti-inflammatory actions. Most of these drugs are for prescription use only, with many being available as generic patches following patent expirations.
Following numerous reports of deaths and life-threatening side effects due to a serious design defect of the reservoir patch risk of drug leakage from the patches , the company moved to a DIA patch design. The main active agents used are capsaicin, various diclofenac ion pairs and lidocaine. In general, the bioequivalence of patch formulations of the same drug can be undertaken using either ex vivo human epidermal penetration studies or by assessment of the plasma drug concentration profiles.
A limitation in these studies was the lack of any apparent clinical efficacy or adverse profile comparisons. A number of comparative bioequivalence studies have also been conducted with nitroglycerin discussed earlier and with fentanyl.
However, some parts of the body trunk and upper arm appear to have similar fluxes, enabling patches to be interchangeably placed at those sites and to achieve similar plasma concentrations. Practically, transdermal systems should not be applied to the waistline as tight clothing may rub or remove the patch. However, these safety ratios mainly relate to adult skin.
Liebelt and Shannon pointed out that many commonly used over-the-counter OTC topical medications, including those containing methyl salicylate, camphor, topical imidazolines and benzocaine, can cause serious toxicity in children when ingested in small doses. Accordingly, transdermal administration has been used to deliver theophylline and caffeine in the premature infant, for whom dosing by conventional routes of administration can be difficult Barrett and Rutter, Transdermal patches have an additional drawback relative to other dosage forms and that is the potential for their ingredients, including both the active drug and the excipients, to induce adverse skin reactions, especially when the dosage form has prolonged contact with the skin for a long period of time.
Most of the cutaneous adverse reactions reported in the literature with transdermal drug delivery systems have been induced by the drug itself, whereas the components of the patch e. Although generally mild and transient, these reactions can result in the discontinuation of the treatment by the patients Murphy and Carmichael, ; Singh and Maibach, On the contrary, even the clonidine patch, with a noticeable degree of sensitization Hogan and Maibach, , is still well accepted and performs well in many patients.
Fentanyl patches have been a continual source for safety concerns. Manufacturing defects i. Fentanyl may also lead to patient issues as a result of the illicit use of fentanyl from these patches or after swallowing fentanyl patches. The US FDA issued Public Health Advisories in and to raise public awareness of the safe use of fentanyl patches and the dangers of accidental exposure FDA, ; , after receiving reports of death and life-threatening side effects in patients using brand name Duragesic and the generic product due to an inappropriate use e.
As a consequence, the US FDA has reinforced education of patients and caregivers for a proper disposal of fentanyl patches after the reports of 26 cases of paediatric accidental exposure to fentanyl over the past 15 years, including 10 deaths and 12 hospitalizations FDA, a,c ,.
Drug utilization rate and residual amount of drug after use of recently approved, fentanyl and nicotine transdermal patches. For instance, the rivastigmine transdermal patch Exelon dosage strength 4. Concerns have also been reported for capsaicin, which normally leads to local warmth or coolness but no burns. The presence of metals e. Nowadays, most patches contain no conducting metal surfaces.
In theory, fever could also result in an increase in plasma drug concentration due to temperature-dependent increases in drug release from the transdermal patch. Three types of studies are normally used to evaluate a finished transdermal patch product: product quality tests, in vitro drug product performance tests and in vivo drug product performance test. The product quality attributes typically include description visual examination of the patch , identification, assay content of drug product , impurities, dosage form uniformity, residual solvent levels, cold flow property adhesive migration out of the edge of the patch during storage or when the patch is applied to the patient , polymorphism and microbial limits.
Crystallization is a particular problem that may arise from supersaturated systems that are thermodynamically unstable and where drug may potentially crystallize out during storage. Low MW surfactants e. In vitro drug product performance usually involves three tests: in vitro drug release, in vitro skin permeation studies and in vitro adhesive tests. In vivo drug product performance pharmacokinetic and in vivo adhesive performances are usually conducted in parallel.
We began this review with a discussion of the original solution and semi-solid products for topical and transdermal delivery. Watkinson pointed out that there are at least nine non-occlusive passive transdermal products, including the approved Nitro-Bid nitroglycerin ointment Fougera delivering about 7. Importantly, two testosterone replacement gels, Androgel and Testim, now carry FDA's strongest black-box warning for secondary exposure in children to application sites, left over gel and unwashed linen FDA, b.
In this context, it is of note that two systems, developed by Acrux Ltd. The development of active patches has however been associated with much false hope with initial commercial success being hampered by commercial, technical and consumer issues Watkinson, This history is probably best illustrated by the mixed success so far in achieving painless local anaesthesia with lidocaine.
Finally, transdermal delivery systems, particularly transdermal patches, are increasingly being used in the paediatric population. A range of transdermal patches i. However, while transdermal delivery can be regarded as a convenient non-invasive method of drug delivery for term infants and older children requiring smaller doses than adults, formulation challenges remain for premature neonates with an immature skin barrier Delgado-Charro and Guy, Topical delivery systems have been used for various ailments and as cosmetics since the arrival of man.
Over time, there has been a definition of suitable drug candidates for transdermal delivery and the associated development of technologies, both passive and active, that has led to delivery enhancement, precision in drug dosing and a better meeting of individual needs. A focus in the further development of drugs in transdermal patches and associated delivery forms remains the finding of sufficiently potent drugs that can penetrate the skin with an appropriate transdermal technology.
A key challenge is to meet clinical and cosmetic needs, which cannot be appropriately met in a cost-effective manner through other routes of delivery. Two authors M.

Guidance for industry: residual drug in transdermal and related drug delivery systems. That helped a lot also. My T was caused by working on the flight line in security during active duty in the Air Force. Like x 2 Informative x 1. Guest , Dec 18, What kind of antibiotics do you believe worsened your T?
Location: forte Antoine. Guest Is this your testimonial that I found in other forum? I wrote about it in the ATA journal and a lot of people found that it helped reduce their tinnitus intensity and volume as well.
These patches are usually used for motion sickness which I used to have with the tinnitus when it was a lot worse. Scopolamine is used in truth serum and used to block certain messages being sent by the central nervous system. Here is more from DrugLib. Scopolamine has many uses including the prevention of motion sickness. It is not clear how Scopolamine prevents nausea and vomiting due to motion sickness.
The vestibular part of the ear is very important for balance. When a person becomes disoriented due to motion, the vestibule sends a signal through nerves to the vomiting center in the brain, and vomiting occurs. Acetylcholine is a chemical that nerves use to transmit messages to each other.
It is believe that Scopolamine prevents communication between the nerves of the vestibule and the vomiting center in the brain by blocking the action of acetylcholine. Scopolamine also may work directly on the vomiting center. Scopolamine must be taken before the onset of motion sickness to be effective.
Mechanism of Action Scopolamine acts by interfering with the transmission of nerve impulses by acetylcholine in the parasympathetic nervous system specifically the vomiting center.
I used to take Trans Derm regularly years ago, when I was active on a sailboat ocean racing crew. I remember it gave me totally crazy dreams but outside of that, had no side effects for me. Think you need a prescription for it in the U.
My guess is it won't "cure" tinnitus. But as Guest says, it could bring relief on bad days. It has a lot less dicey side effects than Trobalt and Neurontin which I also have used. And its not potentially addictive, like a benzo. Worth a try, I think. Informative x 1.
LadyDi , Dec 18, Most antibiotics I have taken worsens the T. Tinnitus Since: 2. These drugs have been around forever -- scopolamine and atropine are primary constituents of Deadly Nightshade, Datura, and other plants which have been used as herbal medicine for thousands of years. There's a huge amount of data about their safety profile and interactions, so I'm a little shocked I've never heard of them being used in this way before. It really doesn't matter where the patch is placed.
I have placed them on the back of my arm on the triceps. The medicine is still dispensed transdermally. Guest , Dec 19, In Italy this drug was under the name of Transcop, now no more in commerce ItalianMan , Dec 19, You mentioned that when your tinnitus is bad , you wear the patch for three days. Are there side effects if you wear it longer?
I am so glad to see these posts. I was getting very scared of what was happening to me. I used the patch for a 5 day cruise and it worked wonderful. I took off the patch and the next day I was extremely dizzy, bad headache, and blurred vision. Just hope the side effects go away soon! I was prescribed the patch due to an inner ear imbalance to correct my vertigo.
The only symptom I've had is the blurry vision and it has been frightening. I took the first patch off after two days but the dizziness returned so I cut the second patch into fourths and am trying that.
Has anyone else had success with cutting the patch and the blurry vision going away? Just returned for a week long cruise and used two patches during the duration. After getting out of the shower I removed the final patch and without thinking immediately put in my contact lenses.
Not certain if medication touched my eyes directly but within five minutes my pupils dilated and my vision became blurred.
I am on day 4 of blurred vision and headaches. I am unable to wear my contact lenses or focus my vision. I cannot read fine print or drive a vehicle due to my vision impairment. I should mention that I am a healthy 29 year old female and I would severely caution anyone against taking this medication I have used the patch for the last nine months after a stroke causing vertigo. Has anyone developed a rash from using patch over an extended period of time to the point of when putting it on a rash appears as welts?
I just returned from a 12 day cruise, where I used the patch the whole time. I didn't get seasick, but I did have side effects of dizziness, drowsiness, and dry mouth. Thought it was worth it. Upon discontinuing use, 12 hours later started severe withdrawal symptoms, just like severe motion sickness: dizziness, nausea, unable to do anything but sit still or sleep.
I've read in other websites the suggestion that using meclazine during this time will help it pass more quickly, which I'm going to try. I never would have used this patch if I had known this would happen.
Not worth it!! I used a transdermal patch prior to surgery and postoperatively as well, I used 3 patches over the course of 2 weeks. I have had continued bouts of nausea and vomiting for 5 weeks now, after stopping the patch. As the patch did its job postoperatively, never again will I use it. The horrible nausea for weeks is not worth the few times I may have vomited post op.
I am incredibly prone to motion sickness, and often get it even on short car rides. Tried the patch when we flew to Uganda 24 hours total of flying and it worked great. I had mild blurred vision while using it but that went away within a day of taking it off. Otherwise I had no side effects. It is now my go-to motion sickness drug. If you get horrible motion sickness like I do, I think it's at least worth a try because it has the potential to make your life so much easier when you travel.
I am a diagnosed vertigo patient, I take a Meclizine tablet daily, have for 25 years. I've used the patch for cruises with excellent results and no withdrawal. When I was on the patch I discontinued use of the Meclizine, which is basically Dramamine. After the cruise I continued the Meclizine. Maybe that is why I didn't have the withdrawal.
So maybe, a week or two of behind the counter Meclizine would help others through that period. I have an upcoming cruise that I am going on with two of my sisters. I am 59, my sisters are 68 and They have never used the patch before. They both have other medicines that they take daily. Does anyone have issues with older age, or medicines that interact? I was hospitalized for four days for severe unresolved post-surgical pain 10 weeks after surgery.
The IV pain meds made me vomit uncontrollably, so I was put on the anti-nausea patch for two days. It helped with the nausea and I took it off upon discharge today. When I got home, my son noticed I had one massively enlarged pupil, while the other one was normal. I'm so grateful I happened to see a site that mentioned that the anti-nausea patch could be the culprit because I was freaking out. Vision is a bit blurry, as well as light sensitivity. Hope it goes away in a day or two. I have severe Vertigo and for a year of my life I spent being so sick, throwing up and everything spinning counter clockwise I had to stay in a very dark quiet room finally after trying everything we went to the patches, that was 3 years ago and other than when I forget to change the patch I have not had a bout of vertigo.
They work wonderful for me. I do not want to think about what will happen to me if I have to go off them. So glad I am not the only one to have withdrawal symptoms! However, Dramamine and Bonnie make me so sleepy I would miss out on all of my cruise travels. The patch is the only thing that prevents my sea sickness and I do plan to continue using it.
I never take the patch off immediately after a trip! I wear it for several days after and then take Dramamine to ease the symptoms after about 5 days or so. I was on a 7 day cruise in the Pacific and prone to Sea sickness. I used 3 patches and kept them on for the airline flights home and day after. They worked very effectively on the cruise and I was not bothered at all by sea sickness. Could not stand up, blurred vision. I immediately went to the internist who diagnosed me with vertigo.
Put me on antivert. This made me feel better, but all I could do was sleep. I missed a week of work after being on vacation which really wasn't good. After going thru the head manoeuevre, I did not have that and looks to be withdrawal symptoms from the transderm patch.
I am still bothered by it after 5 days. After this experience I would rather have dealt with sea sickness or just have used dramamine and the travel bands. Patches have always worked great for me, but I wish my doctor would have mentioned the possibility of withdrawal syndrome after using too long. Just returned from a month long trip across the country in an RV and felt great because of the patches. Every three or four days I removed and replaced with a new one, but after I removed the patch I can barely function due to nausea and dizziness.
I would have much rather dealt with being car sick than having these withdrawal symptoms. Although I am very glad that others have shared their experiences so that I don't waste days and hours at the doctors. So far it's been a week and a half and I still have the symptoms. Tried Scopolamine gel, have to have a compounding pharmacist make it up. Didn't work as well as patch for fishing. Had zero side effects The patch together this ginger tablets worked in preventing seasickness on a 6 day cruise.
I used one patch for a day, replaced it as it wasn't sticking really well, and then another for another 2 days. I was careful to wash my hands after handling them. I had no side effects nor withdrawal symptoms. I tried 2 other OTC pills previously that didn't work, either because I was still seasick or they made me very sleepy.
I would use it again for similar length trip in the future. When I used the patch for an day cruise, I suffered great side effects after taking the patch off. I found that wearing sea bands after taking the patch off helped with my dizziness and nausea. I used the patch for a 7-day cruise and the post patch side effects were not nearly as bad.
It seems the longer you wear it the worst the side effects get. Next time I will cut the patch in half instead of using the whole patch. The side effects I experienced while wearing the patch include extreme dry mouth, dilated pupils, blurry vision, and dizziness. If I wear sea bands while wearing the patch my dizziness goes away. I get really bad motion sickness and I find that the sea bands work wonders combined with the patch.
I get severely sea sick the minute the boat starts to move and puke until I am back on shore. I used the patch several years ago when sailing in open ocean. With the patch, when in big waves and the hearty sailors were feeling a bit queasy, I could go below deck and eat a sandwich, immune to sea sickness. Got a bit of dry mouth and felt like cotton in the head at first, but for a week two patches it was wonderful. The patch went out of production for a while. I am going on a whale watch soon and found this site.
Delighted to see that the patch is back! Patch seemed to be effective during cruise but now it is 3rd day off it and I am suffering terrible dizziness, blurred vision, disorientation, tingling of hands and feet, sensitivity to light. I will not be taking this again.
Used the patch in the past with no problems, but now developed terrible itchy and oozing rash from it. Too bad because it worked really well. I wouldn't recommend the patch. I used it for three days, and ended up with severe vertigo and depersonalization. Seven years later I still have it, they think it was a reaction to the patch. Is that true? Can't find any info on it. I had a total knee replacement and was very sick, nauseated and throwing up after surgery.
My doctor tried various pain pills and they all made me sick. Finally, he gave me the patch and it was like a miracle, I instantly felt better. I am at home still using the patch. It worked for me. I used the patch for the first time on a 5 day cruise due to motion sickness. The patch worked great. However, I didn't know of the side effects after removing the patches. I will not use the patch again and will take the risk of motion sickness on the ship.
Side effects are worse than motion sickness! I have worn these patches for quite a while. They are the only thing that helps my motion sickness. I always experience some mild rebound effects upon removing one that I have been wearing for several days, but I personally would never wear two or three of these back to back over the course of say a week.
I just keep the same one on for more than 72hrs. After the episode of vertigo I've been with motion sickness for more than 8 months. I'm very frustrated that the only cure available for me is these patches. I haven't had any of the side effects mentioned here. Maybe is because this patches are meant for people who are ill and not for people to go on cruise ships. I've found that doing yoga shoulder stands have helped with the motion sickness.
I'm off the patch right now and I'm looking for natural remedies for motion sickness. If someone knows some please leave a comment. My 80 year old husband with Parkinson's disease was prescribed this to help control drooling.
Within 12 hours he began to hallucinate, become incoherent, unable to sleep. He wanted to get a gun to shoot strange creatures. Awful, frightening. After removing the patch, it took 3 days for him to return to normal. What a terrible experience. Please consider this especially in the elderly. I have been in the roughest of seas. Cruises are a breeze and rarely does anyone get motion sickness People worry too much, Cruise ships aren't destroyers in 20 foot waves. Deep sea fishing can make people sick.
Not me. A buddy used the patch and had zero problem on a 72 hour trip And man did we catch some excellent fish. I think very few people get side effects. Those that do post. Scopalamine has been proven safe and effective by the FDA. Use as directed. We drank loads of beer as well. Can't wait to go back in two weeks. If you google, you will see the exercises that will stop the dizziness. At first I had to do them every day for a week, now the symptoms only reoccur maybe every 6 months or more and after only a few days of exercises the symptoms disappear.
Good Luck. Beware - I wore the patch for 12 days and then became violently sick on my 15 hour flight home. I could not sip an ounce of any liquid without throwing up. A wheelchair was needed to my connecting gate - dizzy, extremely weak.
On my previous 7 days cruise with the patch I had no withdrawal symptoms. I wore the Transderm Scop patch over about 2 doses the first set of time, and was fine. The second set of time, though, I had added Abilify to my regular drugs, and that dilated an eye after the second dose. I took the patch off, and it resolved itself within 48 hours, but since I'm still taking Abilify, I don't feel comfortable using the patch anymore.
It's too bad, because I have severe motion sickness, and the patch was the only thing that ever worked for me. I took a cruise last year and wore the patch the whole time. I took it off the day we got off the ship and couldn't function the next day due to dizziness, massive headache, and nausea. I was told by experienced cruisers that I had taken the patch off too soon and that I should've kept it on for another day or two.
We just got off our most recent cruise yesterday and I kept the patch on and still have it on today because I'm terrified of not being able to function tomorrow for a wedding I am supposed to photograph I'm a wedding photographer.
I'm nervous that I'm not supposed to keep the patch on beyond the 72 hour mark yesterday morning would have been the 72 hour mark. Does anyone have any insight into whether it's safe for me to keep this patch on through tomorrow night which will end up being more than 48 hours past that 3 day mark?
Thanks in advance! I leave it on until it falls off on its own during the cruise and am ok with no motion sickness the rest of the time. I was given scolpomine before a surgery procedure. I usually wake up from surgery and get sick. This worked great. I also get sea sick, so I was prescribed this again. Not sick at all. Then I filled the prescription the second time and was so sea sick.
I thought the package looked different but put it on with full confidence. So disappointed. What do you think happened? I need the good stuff! I only wore the patch for about 12 hours till it made me feel horrible. Colors are way more vibrant and now very sensitive to light. Throat feels like it's hard to swallow.
