My stomach is really sensitive to some medications (antibiotics, even some over the counter stuff), but unfortunately, I don't usually know what meds will bother me until I take them. When I do take something that bothers my stomach, the pain is really intense and it can take hours to go away. Pepto-bismol and tums don't help me at all in these cases. I'd like to say that I'll just make sure I'll never take a medication again that bothers me, but I think that's unlikely. Does anyone else have this problem and is there anything that can be done?
