I am taking Bactrim for a UTI and have side effects of hands shaking, gassy stomach, headache, loss of appetite, and irritability. There are 4 pills left and I am afraid to finish them. Is a substitute for Bactrim DS tablet SMX-TMP DS TAB? The script is 2 tablets twice a day. Should I just discontinue them or reduce them to one a day? ## Those can be normal side effects of this medication, according to FDA reports. You may also experience nausea, dizziness, and diarrhea. And SMX-TMP DS is just an abbreviation for the ingredients in Bactrim DS. An allergic reaction is listed by the FDA as possibly including fever, chills, trouble breathing, hives, and swelling. This is a very strong antibiotic, though it is not usually the first choice for a UTI. Are you on any other medications? Have yo...

I need to know of any side effects that may occur while taking this medication. ## Are there any risks to taking this medication understanding that the patient is 35 weeks pregnant? ## I took it for sinusitis/ear infection and got a terrible case of hives. ## You can't take Bactrim if you are allergic to sulfa (ie. that case of hives) ## Rash can occur ## My 9yr old daughter was prescribed Bactrim for treatment of a bladder infection. 2 pills twice a day for 7 days on 8th day she broke out in severe hives and a red pin point rash all over her body head to toes she also ran a fever.

bacterial sinus infection AFTER starting antibiotics for another reason
4 Replies RSS Share
i was recently prescribed bactrim (sulfamethoxazole and trimethoprim) for an infected burn. on the second day, i woke up with a really sore throat. by night, i had a fever, and the next morning, i had a sinus infection--which i used to get chronically from about 11 years ago, up until 4 years ago, in which time ive only had one. a day later i had a productive cough, semi bad but nowhere near as bad as the bronchitus the sinus infections would, after months, eventually turn into. those infectionswere clearly bacterial as whenever I did end up taking antibiotics, they always ended within a few days. I tried to ride them through to defer antibiotic resistance and such, and i cant rememeber if i ever did, because they WOULDNT go away. regardless, i went back to the dr this time after gettin...

I'm having pain in my right ear n also pressure and I can't hear, it's like I hear echo. Sometimes when I swallow saliva my pain comes really bad. ## Hello, Yoli! How are you? Yes, this is a broad spectrum antibiotic that is used to treat various types of bacterial infections. However, you shouldn't take it, unless your doctor has confirmed that you have an infection and instructed you to take it, because taking it when it is not appropriate creates the risk of your developing antibiotic resistant bacteria. The FDA lists the typical side effects of this medication as possibly including nausea, dizziness, headache, non-allergic skin rash and diarrhea. Is there anything else I can help with? ## can bactrim help get rid of shingles? my mother has had a shingles break out be...

My mouth is so swollen with blisters all inside my 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 ins...

My husband was prescribed this pill for a staph infection. He has dementia and has had total confusion, craziness, sleeplessness and anger since taking this pill (2 pills in am and 2 pills in PM). Could this be a side effect? ## Hi Mimi, According to the MayoClinic... confusion, irritability, and trouble sleeping are all listed as possible side effects of Bactrim. However what's interesting to me is that they are reported under a category called "incidence not known", which makes me wonder if they haven't actually been able to prove that Bactrim is the cause even though patients have experienced such symptoms during their time on the medication. My hunch says that Bactrim is a strong suspect, but I would still encourage you to discuss possible solutions with his doctor i...

WHAT IS THE SHELF LIFE FOR THIS MEDICATION? ## Hello, Mouse! How are you? If you have the tablets in a bottle as dispensed by your pharmacy, then the expiration date is one year from the day you had it filled. This is due to the fact that the containers they use expose it to the elements that contribute to degradation. Is there anything else I can help with? ## I have a prescription bottle of Bactrim 800 mg dated 7/10/17 and I was wondering if this prescription is still good?

sulfameth/trimethoprim 800-160 ## I have been on this drug for a week now and I have been experiencing a hard time sleeping and I wake up every hour on the hour and when I first was on it I did not sleep for four days and I never had sleeping problems before. When I do sleep I also get really weird dreams. Has anyone experienced this? ## Yes- I am having problems sleeping and weird dreams also. Ooh-well; it will stop soon. I will complete the medication and hopefully be done with it. ## This medication is a combination of two antibiotics, and yes, they will cause sleep problems for some people, but this will wear off if you are on it for awhile, or it you complete your course of treatment. ## I have been put on Bactrim for my acne treatment. I also have problem with sleeping and wierd d...

Becotrim 960

I filled a mail order prescription for bactrim and when i received it, it said becotrim 960. Is this the same? The pills came from india / combitic global caplet pvt ltd. ## Bactrim is sold in the U.S. as an antibiotic for bacterial infections. I researched and looked for becotrim 960. I'm unable to find anything about the becotrim. You said it came from India. The United States do import medications because we do have manufacturing plants in countries like India. However, did you have a prescription for it or did you just wanted to order from a site without having to use a prescription? The pill could very well be Bactrim or it could very well be useless. This is why I go to a local pharmacy, which will carry this product. Did the pharmacy you use have Bactrim DS (double strength)....
