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.

does bactrim expire
3 Replies RSS
I have bactrim that expired in May 2015. Is it safe to take now even though it's outdated? ## Hello, Kenyada! How are you? This medication does not become dangerous once it's expired, but it does start to lose efficacy, so it may not fully eradicate infectious bacteria, which could create the risk of your developing antibiotic resistant bacteria. Thus, it would be best to dispose of it and see your doctor for a new supply. The FDA lists the typical side effects of antibiotics as possibly including nausea, dizziness, headache, non-allergic skin rash, and diarrhea. Is there anything else I can help with? ## My wife found some opened old bactrim from 2007. It was stored in the heat and not taken care of. Just a few tablets left. Anyways she wasn't thinking clearly due to vomiti...

Having taken Bactrim for about 3 weeks for a prostate infection, it now seems that the first urination after taking the pill exaggerates or possibly causes an extra burning sensation. Is this ever reported as a side effect ## Bactrim contains Sulfamethoxazole and Trimethoprim and being that it's a sulfa drug, it's well known to cause odd side effects and weight reactions in many people that take it. As a matter of fact, I wouldn't recommend it to anyone, unless it's their only option for treating their infection. Learn more Bactrim details here. That said, yes there's a chance that the medication could be causing the problem, though there is also still a chance that it is unrelated. However, from personal experience, since I had a bad reaction to this myself last sum...

Hi, my 5 weeks old baby has what is called colic so the Dr said. He cries and folds himself and make his stomach hard and pulls his legs. However the Dr gave him Ivitrim Suspension 50mL to drink and now I want to know if it's safe for my hiv negative baby? What could be the side effects? ## Hello, Penny! How are you and your son?
