Does Bactrim Go Bad After It Expires?

Updated

My son had an ear infection a month ago and was prescribed a 10 day course of Bactrim. He now has another ear infection and has been prescribed it again. Is it ok to use the bactrim left from a month ago or should I get the new script filled? Other antibiotics he's had have specifically said to throw away 14 days after mixing.

Hi Miriam, by rights, your suppose 2 complete the whole course of antibiotics right away. Just because u or your so starts. 2 feel better b 4 your done the 10 day supply, u need 2 complete the 10 days. Maybe, that is why the infection came back. So, I would call the Dr and get a new prescription . Hope your son feels better.

He did finish the 10 days but there was more than that in the bottle.

Hello, Miriam! If it is a liquid then it should be disposed of, because they tend to degrade in a very short period of time.

Thus, you should fill the new one. Side effects may include nausea, dizziness, non-allergic skin rash and diarrhea.

Is there anything else I can help with?
