My mouth is so swollen with blisters all inside my mouth.....now it has started to affect my private area as well with same symptoms. I cant eat and it burns all day long. I only took 4 pills when this started. Please help if you can.

Rhonda, I have exactly the same reaction to this drug. Blisters on the lips, very sore tongue and blisters on genital area.

Hi Rhonda,what is the dose you are taking and it would be to your benifit to ask your doctor for a different medication or if it were me I would only take half a dose at a time every 4 to 6 hours.

I am not sure if you are going to get a response, since this post was made in 2007.

However, these reactions do happen to some people and in such instances, you should call your doctor immediately.

Yes, I had the same reaction to bactrim. Was given Bactrim for a UTI. Doc thought I may have herpes due to my reaction, but it turned out only a reaction to the bactrim. I was sure I didn't have herpes for obvious reasons, but then I heard herpes can stay dormant for years. Waited days to get the final results...which was agony in itself. Damn Bactrim!! I had taken this drug previously, but with only one minor sore in my vaginal area and slight sore in my mouth. This time was MUCH worse.Several blisters in my mount, vaginal area and rectum. Shooting aches and pains in lower back and legs which lasted for weeks. It seems each time the allergic reactions can get worse. I took 4 days worth and then realized it was the bactrim causing the problems. Will never take this drug again!

hi, every medicine has its side effects, cheap bactrim have mild side effects, i had these kind of effects and my doctor said it is normal there is nothing to worry and if you think they are severe you can discuss it with your doctor about this he is the only person who will suggest you about the effects or may be if he thinks he alter your dose according the condition.

Wow I have had THE EXACT same reaction to Bactrim these past 6 days. I only took four pills and I was in agony. Immediately got a killer yeast infection, one of the worst in my life, horrible vaginal area burning and pain and itch. I had trouble urinating with extreme pain( worse than the original UTI I was prescribed it for), and hives and itching all over my body. I stopped taking it 4 days ago. I really hope these sores in my mouth go away soon, I have braces, and it makes it sooooo much worse! Cant EAT! Cant talk! wtf
I dealt with all of it at home, thinking it would all go away. But what brought me to the hospital was when my throat stated to constrict, and I could believe. It was a brand new side effect every day. So horrible. They, too, at the ER I ended up at last night, thought I had an std. I really believe this has all been a reaction to the Bactrim. Especially after seeing so many people here on this site, and many, many, other sites having the EXACT SAME problem!!
It needs to be taken off the market.
Bactrim needs to be stopped.

The same has happened to me. Was prescribed the genetic form of Bactrim and have gotten they 5 days of the medication. At first I was having terrible irritation on my vagina and then came the herpes like sores. So painful!!!!!!! I've contacted my doctor and won'tget a different antibiotic until my appointment monday morning. Should I be taking this until then?

This side effect was never disclosed to me prior to taking it. I would have never taken it. Any suggestions on a safe replacement antibiotic?

Thanks

I have had a similar problem with the only affected area being multiple blisters on my lips and nose. I get frequent UTI's so I have been taking this drug every 2 or 3 months for the past year. My usual reaction to the drug is fatigue and some nausea issues. However, this time, areas of my lips and nose became swollen, started to itch, remained relatively skin-colored until they formed into blisters which oozed clear liquid when popped. Now they are sore, deep red, and painful. I keep applying Vaseline every hour but definitely uncomfortable and NOT pretty. At first I was confused that I may have a cold sore because I have been particularly stressed lately with my university's finals week. However, I do not have a history of exposure to the virus that causes them. So now I think maybe it's a reaction to this drug based on these comments. Is my reaction similar to everyone else? Thanks!

I get UTI's pretty often, so just last week I went to my doctor for a stronger antibiotic to help get rid of them for good. He prescribed me Bactrim DS and everything went well for the first few days on this medication. But it was just yesterday morning I woke up with a fever and had no idea what caused it since there were no other symptoms. So I just ignored that and went on with my day. Later that night I noticed redness and small sores in my vagina and immediately started to freak out. I know it's not an STD so I made the connection to this new sulfa drug, I must have an allergy to it. Today my fevers are gone but the sores and swelling are still there, maybe a little worse even. My doctor said he doesn't think it has anything to do with the Bactrim but I definitely think he's wrong seeing all these same issues on this forum and many others. I'm getting an appointment with a gynecologist asap and trying to avoid the hospital even though there's a good deal of pain. Honestly it's just kind of a relief to see there's not something extremely wrong with me and these side effects are out there. Bactrim should stop being prescribed to people so often!

I took one dose of Bactrim DS for a UTI and I'm an RN, so I know it's not a venereal disease! I woke up with swollen gums, lil mouth sores and a very itchy vagina, not to mention the rest of my body feels like I got hit by a bus....it's the sulfa ladies, you are allergic to sulfa. I used a topical burn cream with sulfa in it and something similar occurred.

After one dose I got a large sore on the inside of my mouth. Does anyone know how I can speed up the healing process? I discontinued the bactrim after that one use but this sore is so painful. I'd really like to expedite the healing process.

I have been on this drug twice and both times I have had the same problem mostly in the genitals .After about the 3rd pill my genitals got really red and sore at the tip around the eurethra. I also had itching around where I was circumcised and shaft.I knew it wasn't an std and I remembered that I had taken it before as bactrum and this time it was Septra.This is a bad drug for some people .Its very painful and takes at least a week to start healing and you need to keep affected are clean and I put neosporin on it to help it heal.They need to stop this drug before it causes a death.

I was prescribed Bactrim for a UTI. I get UTI's frequently, unfortunately. This time I was out of town for Christmas, I ended up going to the ER because I wanted to nip it in the bud and not have UTI pain ruin Christmas. The Dr. at the ER said they don't like to prescribe Cipro because it's the last line of defense before intravenous antibiotics. I thought that was sound logic and wondered why my regular doctor would always put me on Cipro. Well, now I know, the side effect from Bactrim are bad. I'm on day 7 of 10 and I can't take this drug anymore. Since day 2 I have felt a little off, but now on day 7 I feel horrible - tired with a throbbing neck. Yesterday I noticed the lymph nodes in my neck were kind of tender, and now after having taken my morning dose, they feel even worse. They are big and tender and now one on the back of my neck is also swollen and tender. I've never in my life experienced my lymph nodes swelling up being sore like this. My poor body and what it is going through. I have also had a very bad headache off and on while taking this from day 1. No terrible rash yet like others report, but I fear that will be the next step if I continue ingesting this medicine. This isn't a feasible solution if it makes a person this sick.

I've taken Bactrim DS so many times I've lost count but the last 2 times it has caused the blisters on my lips. The first time I didn't know what was going on so I just continued taking the antibiotics because like I said I've tolerated it numerous times in the past. Well the blisters eventually went away after about a week after being off of Bactrim. So just 3 days ago I had to take it again and after one day of being on it I woke up with my lips swollen and tingling so obviously I stopped taken it immediately. Well the next day this blisters on my lips showed up again. Ugh!! So painful and ugly! What I find that helps it taken a warm washcloth and just letting it sit on my lips, the blisters will pop and you can lightly rub the dead skin off (this is painful but it will heal in a day or two which means less time walking around with lips that look infected with herpes. BTW it's NOT herpes!)

Anyways my concern is why this all of the sudden? I've taken this antibiotic for years for a reoccurring abscess/boil on my leg that flares up every now and then. Now I don't know what to do, amoxicillin isn't strong enough to get rid of it, Bactrim is the only antibiotic that I've found will make it go away. Does anybody have a clue what this could mean? Did I just develop a random sulfa allergy overnight?

Stop taking the antibiotic and report to your doctor. You are having allergic reaction.

I was prescribed Bactrim after having a cyst drained. After 2 doses, my eye became itchy and swollen and it began to itch in my vagina area. My blood sugar was running high and I usually get itchy down there when it happens so I didn’t think of it. Once the blisters started, I immediately knew I was having an allergic reaction to the medicine (I had the same reaction to Meloxicam in January). I previously took Valtrex when it happened and had to beg my doctor to prescribe it (I went to my OB the first time since I had no idea what it was). Hoping it works this time. I’m also applying Lidocaine on the blisters since it hurts and stings when I go to the bathroom and using Benadryl for my eye. I was prescribed another antibiotic for the cyst but I’m super afraid to take it since I’ve had this reaction with the last 2 I’ve taken.

I am sad but also fortified by your similar experiences with Bactrim. I was recently presented with a subcutaneous cyst at the top of my leg and went to my primary care to have it lanced. However the PA wanted to address it with antibiotics as first approach and so I agreed to try. Bactrim was prescribed. On day 7 I began to experience severe neck stiffening and headache. I mistook for driving fatigue and continued taking. On day 8 and 9 I had high fever, marbling of skin, diarrhea, extreme loss of energy, all over body aches, dizziness and loss of appetite. I noticed diarrhea in the drug side effect possibilities, and wrote he other off as the flu. However, I began to notice severe swelling of my genital area. It was itchy, painful with painful urination and it was difficult to walk or bend over. I noticed a couple of blisters on the outside opening to the vagina and some white discharge which made me think yeast infection. I kept taking the sulfamethoxazole, never having had an allergic reaction to a drug and only knowing that it is detrimental not to consume the complete antibiotic dose. On day 10 I continued having marbling of skin, fever, and other symptoms with now a reddening of my face, neck and chest. I had an appointment the next day to follow up with the prescribing doctor and called to see if I could get in earlier. I could hardly walk and was generally miserable. They recognized the allergic reaction to sulfa, but proceeded to tell me I had genital herpes. Me, married to the same man for 24 years exclusively! Doctor insisted that he must have had an affair and passed it to me. Well, doctor was wrong and I won’t be seeing her again. It has been 2 weeks and there are still some residual side effects like neck stiffness and headache, and some of the blisters inside remain, but each day, and with drinking many fluids, I flush the sulfa out of my body and feel a little bit better. It was totally demeaning to be talked down to by the doctor and her PA, and nobody even called to follow up about the blood work or samples that they took. Just really done with them and want others to be wary of this drug.

I am taking Bactrim for a UTI and on the 4th day today I started feeling I can’t pee, like very slow flow... and it feels like pressure down there. The doctor told me to stop taking it. I took it a year ago and didn’t have this problem. Is this a side effect of this med and will it go away?

For the 3rd time I end up in the ER and the doctor had to give me a steroid shot to ease the burning pains and pains from the ulcer that Bactrim was causing. I went through 9 days of hell and there is not a damn thing that will help you except the steroid shot and it only last for 24 hours but it was instant relief and it gave enough time foe the new antibiotic to kick in and still I lay on bed for days in pain due to the burns from the Bactrim. When I urinated I used the sitz bath bottle with tubing to let cold water running through it every time i peed and I had to use the cold button on the blow dryer to dry down there because I was burnt so bad my skin was peeling. Doctor said I was am allergic to the sulfur like my mother, so chances are if mom is allergic than maybe so are you. Anyway KY jelly helps some at bed time or anytime it helps, lose the underware and let your fan blow cold air there so you can get some rest. The scary part is the burning and skin peeling can be symptoms from John Stephensons disease which is cause by Bactrim.
Bactrim is one of the worst antibiotics and should not even be given to people, look at all the complaints, there is more to this medicain than me being allergic to it, seriously are all these people allergic to it as well??? I don't think that is the case!

Hi all! After going through the agony everyone here described — twice — my doctor figured out it wasn’t lichen planus but instead Stevens Johnson Syndrome. The second time it happened, I immediately started using clobetasol 0.05 ointment downstairs which stopped it from getting truly bad. Instead, my entire mouth erupted and the pain was excruciating. I couldn’t eat or talk, swallowing felt like I had strep, and it wasn’t until I was patched through to the emergency dermatologist at the hospital that someone realized what was going on. I’m going in first thing tomorrow for a biopsy.

If you can’t get to a doctor, homemade “Magic Mouthwash” can help — equal parts liquid Benadryl and maalox, swirled, gargled then spit 4xs a day. Avoid eating and drinking for 30 min afterward.

I also now know I can use the clobetasol cream in my mouth, but they gave me the gel version instead. If you’re getting flu-like symptoms, the sores and difficulty swallowing, call your dr and ask about Stevens Johnson ASAP. And stop taking the bactrim immediately! (Assuming you’re using it for a UTI and not MRSA)
