Bactrim Side Effects (Page 9)
(Newest replies first)

I am curious if anyone else has had any of these side effects from taking bactrim. 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.

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 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.

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 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!

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

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.

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.

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!

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.

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.
