For Hyperhidrosis "Tried Qbrexza for underarm sweating. This product does what it’s supposed to - it stops sweating. However, the side effects are simply not worth it. I had severe dry mouth and nose within 4 hrs of using under my arms. I did not sweat anywhere else either - hands, face, groin, feet, for that matter. I could barely talk or swallow and drank/sipped water constantly. It’s now been 14 hours since initial application, and I’m up at 3:30 am unable to sleep due to this dry mouth. I had to skip dinner because I had zero saliva to help break down my food. My eyes are also looking red and dry, but I’m not ‘feeling’ any issue with them. This dry mouth is incredibly horrible though. Had I known it was going to be this severe, I’d have passed in a heartbeat. After all the water I have drunk in the past 14 hours - literally over 1.5 gallons, I am worried as peeing is getting increasingly difficult."

For Hyperhidrosis "HOLY MOLY. I used to use this product off and on because I would forget about applying it at night, but since quarantine hit, I decided to actually have a nighttime routine and I started using one pad a day regularly, and I noticed I stopped sweating... everywhere. It was so weird because I’ve sweat literally everywhere (mostly my underarms) for all of my life. I have always suffered from hyperhidrosis. Anyway, one morning I woke up with the WORST dry mouth I have EVER experienced. To the point where I was choking. My throat was so sore it was unbearable and my vision was so blurred. I am literally depressed because this actually stopped my sweating, but the side effects are just too much to handle."

For Hyperhidrosis "Have been using Qbrexza for six months for underarm sweating. Was working great. In the past two weeks, though, the side effects have come out of nowhere and hit me hard. Excessive dry mouth to the point of choking on food, urinary problems, blurred vision and inability to sweat. I was working out, doing my normal routine and spiked a crazy high fever. At first, I thought it was the flu, but I was fine the next day. Went to work out tonight, same thing happened and my coach noticed I wasn’t sweating. Stopping immediately. Will be calling my dermatologist tomorrow!"

For Hyperhidrosis "Horrible!! Be careful if you use this on teenagers or young children. My daughter is 13, she used ONE! One! wipe, she ended up in the emergency room with bladder blockage, and the inside of her mouth turned white and super dry. She wasn’t able to eat or drink for over 48 hours. She was telling me she wants to cry, and she was so dry that no tears would come out. The medicine was over $500! Plus, the emergency room and the doctor's appointment to follow up, plus the medicine to get her back to normal, over $3000 in hospital deductible. I contacted the manufacturer, and I only got, 'I’m sorry that happened to her.' At least they reimbursed the medication, but not the rest. It's a very expensive risk and puts your child at risk, not worth it!!!!"

For Hyperhidrosis "Happy that something finally worked for my underarm sweating. But, as many have stated, side effects are not worth it. Urinary retention, dry mouth, blurred vision, and I don't sweat anywhere else. A shame side effects are so bad."

For Hyperhidrosis "The drug was great at eliminating my sweat problem, but at what cost? I experienced almost all side effects, even the severe. I got hives and was given several antihistamines from doctors because they couldn't figure out why they wouldn't go away. Later to find out that antihistamines have a negative reaction when taken with Qbrexza, so my hives just kept getting worse. Since then, I've experienced terrible dry mouth, urinary tract issues, and just this week began experiencing blurred vision. I went to the eye doctor, and he confirmed it was probably the medication since my pupils were incredibly dilated, which is also a side effect of the medication. I've never had an allergic reaction to any kind of medication. I wish I didn't have this experience with this medication since it does seem to work."

For Hyperhidrosis "Worked amazing from day 1, however, the side effects were horrible. Excessive dry mouth, couldn’t even eat. Dilated pupils, extremely sensitive to the sun. Also stopped sweating from everywhere, no matter how hot it was. This is scary and could lead to heat stroke quickly. My doc told me to discontinue immediately. Very upset by this as it’s the first thing that has ever stopped my underarm sweating."

For Hyperhidrosis "First night with Qbrexza, just 1 wipe, and I am having half of the side effects: dry mouth, dry nose, itchy throat, blurred vision. This isn't worth the risk. Now I'm up at 3 a.m. in the morning writing this because I'm uncomfortable and can't go to sleep due to excessive dry mouth and nose... Ugh... Aggravating... I will never try it again."

For Hyperhidrosis "First day on Qbrexza, I woke up with a dried throat. Next day, I decided to use it around 5 pm and drink a lot of water, and I had no issues. I know side effects might vary, but 4 months in, and the only side effect is a dry throat once in a blue moon. Literally, the best thing ever, I can finally wear normal clothes."

For Hyperhidrosis "I used this medication for a week, and it really worked. However, on day 5, I got every single side effect to the extreme: dry mouth, throat, eyes, nose, blurred vision, distended bladder, and trouble urinating. I also stopped sweating from all other parts of my body, and when I exercised, my face got extremely red, and I began overheating. The benefits are absolutely not worth enduring the side effects. I won’t even continue trying to stick this out to see if they go away."

For Hyperhidrosis "I had been on Drysol for years (I'm in my 30s); however, it was becoming increasingly difficult for my pharmacy to get, and the itching on application nights would keep me up. My dermatologist suggested Qbrexza, and I've been pleased, especially as I find the wipes far easier to apply than Drysol. I have a little itching after application, but it's nothing compared to what I experienced with Drysol. I did have severe dry mouth and throat irritation during the first week or so, but I increased my water intake, and this drastically decreased (possibly as my body adjusted to the medication). Everyone responds to medications differently, but for me, the benefits far outweigh the risks."

For Hyperhidrosis "I use Qbrexza under my arms, and it has seriously changed my life. I’m allergic to aluminum, so most other options just made my sweating worse. I’m a young college student, so I also didn’t want to try any pill that might have other lasting side effects. I think it’s important to follow the directions EXACTLY. Only one swipe per area, wash hands immediately. Doing anything outside of that exactly has given me the side effects others have complained about. I did have dry mouth when I first started it, but it went away within about a week of use. I did sort of struggle to get my insurance to cover this expensive drug, and it had to come from a specialty pharmacy, but it’s been completely worth it. I can wear sweaters, and I don’t have to wash the straps of my book bag of sweat anymore."

For Hyperhidrosis "I have been using Qbrexza for a few months now, and it works great! I was using it every day and did experience dry mouth at times, so I switched to every other day, and it made a world of difference! I have even found that lately I can go a few days or even a week without using it, and I still stay dry. I would recommend spacing it out if the side effects become too much. Definitely wear gloves when you apply it to avoid unnecessary contact with other parts of your skin."

For Hyperhidrosis "I've experienced severe hyperhidrosis for over 20 years. My dermatologist had a sample and suggested it. I followed the instructions, applying to both underarms in the late afternoon. I woke up in the middle of the night with a major headache, dry mouth, and throat that felt like it was swollen. I drank water, and it was painful going down and caused a sore throat. I will say that it was effective the following day with no sweat. However, I had to leave work due to fatigue. This product works without question. I will not take it again because the risks outweigh the reward. I would recommend going with a smaller dosage to minimize the symptoms."

For Hyperhidrosis "My dermatologist told me about the wipes. I never knew about them, she gave me 2 weeks of samples, and I literally noticed the difference within the first 3 days. I have suffered for 18 years, and now it feels amazing to be without dry underarms! I can wear white shirts again, I can wear anything! However, I do notice the dry mouth at times. Just drink lots of water, and ONLY wipe once per arm. When I wipe more than once, the dry mouth is worse. Truly a change in my life."

For Hyperhidrosis "This worked great for my armpits, but I’ve been sick for two months and only just realized this is the cause of it. Dry mouth/throat, can’t see due to blurry and out of focus, urine retention, infected throat. I've been to my family doctor four times in a month, had two antibiotics, had an ENT scope my nose, had an upper endoscopy in a week, and am about to see a urologist. Multiple blood tests and urine tests were run and all came back fine. It hit me all of a sudden, I thought about these wipes. My family doctor was not aware I used them. The dermatologist refused to accept this is caused by these wipes and wanted me to continue. I will not continue to use this. I’ve literally been sick for two months over these wipes. Barely sleeping because of having to use the bathroom 8-10 times a night."

For Hyperhidrosis "Qbrexza has made my life so much better. I used to sweat through a shirt within 5 minutes of putting it on. I dreaded school and work, where I had to wear uniform shirts that weren’t black. It was so bad that I bought underarm liners to hide the sweating. Now I put on whatever I want and don’t even have to worry about it. The side effects really aren’t that bad. If you want to fix the sweating issue, then you’re going to have to deal with some side effects. I’ve had all the side effects: blurred vision, dry mouth, etc. They go away completely after about a month of use anyway. The only one I’ve noticed has gotten worse is itching. I’d recommend using deodorant without aluminum and fanning the application site after using the wipe. If you don’t let the medication dry, it doesn’t work as effectively."

For Hyperhidrosis "Worked great the first week, and then I got the most horrible rash that keeps getting worse and is spreading, although I stopped taking the medication 10 days ago. My mouth began to get so dry to the point of choking. I am still itchy, red, and irritated, and the rash is spreading down my arms and breasts. Qbrexza stops the sweating, but the side effects are dangerous."

For Hyperhidrosis "Worked a little bit too well, always try before you buy! I got a sample of Qbrexza from my dermatologist. I followed the directions (washing my hands to make sure it didn’t get into my mouth or eyes), used it on my underarms, and within 4 hours I had a super dry throat! Could barely talk. When I woke up the next day, it was the worst thing ever. My mouth and throat were so dry and swollen I felt like I was choking trying to breathe. I couldn’t drink anything because it hurt so badly to swallow. My tongue was bright white and my eyes bright red. Everything hurt so badly I wanted to cry (but I couldn’t)! It worked well for sweating, but I recommend you try it out to see how you react before getting a full prescription... As someone who tends to be a bit more sensitive to drugs and a teen, I will not continue using :("

For Hyperhidrosis "I have been using this product for over one month, and this has changed my life for the good. I had to wear pads under my arms and take soap and a washcloth to work and wash my armpits at work and keep clinical deodorant on me at all times. When I wake up in the morning, I am sweating, and my pits would stink. I used this product at night and woke up sweat-free with no foul smell. However, I have a very dry mouth, but I deal with it with Act's dry mouth product and water. I am no longer scared/worried about being outside anymore. I can enjoy life."

For Hyperhidrosis "Used it once and will be throwing it away immediately. I can't imagine what is in this to cause these side effects. My throat is so dry, I'm panicking and feel like I might choke. My skin is bright red, never experienced that before. I would rather sweat my ass off than feel like this. Can't be safe."

For Hyperhidrosis "Started with samples of Qbrexza during their trial phase, I’ve been prescribed these wipes for over a year. I endured the horrible side effects: blurred vision, dry mouth (excessively dry, I couldn’t talk or eat and eventually took supplements for dry mouth), but passed through with the thought it could get better and I had a temporary sense of normality. The symptoms never left, and eventually the wipes stopped working for me altogether, I would apply them and endure the stinging but still sweated excessively. Trying Miradry soon."

For Hyperhidrosis "I used it once as directed, and the side effects I had were horrible. I almost passed out. My hands and face got swollen and red, I had excessive dry mouth and throat, couldn’t even drink water, and a terrible headache for 24 hours. I've never had an allergic reaction to any kind of medication before."
