shelf life sulfamethoxazole
5 Replies RSS
I want to long-term store sulfamethoxazole for potential emergency use. What is the PRACTICAL shelf-life of this antibiotic? Forget about the manufacturer's statements. I want a real-world shelf life and storage instructions. ## From what I could gather, the estimated shelf life of the oral suspension and tablets are both 5 years. The manufacturer's storage instructions also suggest keeping it at room temperature and out of direct sunlight (below 86 degrees fahrenheit), to help prevent further degradation. According to a Harvard Medical School family health article, most types of medications are actually safe to use up to 10 to 15 years after their supposed expiration date listed by the manufacturer. However, there are some antibiotics in the Cycline class, which can be dangerou...

My mom started this med on 11/28. Today 11/29, her legs felt week and the dr said it is unlikely the med I gave her tonight and I am worried to death. I am afraid something might happen cuz of this med. ## That might be a side effect of the medication, according to the FDA, she may also experience nausea, dizziness, headache, non-allergic skin rash, and diarrhea. It is usually nothing to worry about and things should go away, a week or so, after she finishes her course of treatment. However, if it becomes severe, or dangerous, it would be best to consult her doctor, again. Is she on any other medications?
