I've been dealing with some really bad diarrhea, and I was prescribed Loperamide/simethicone 2-125mg Tabs. The doctor said it would help with the cramps and gas. I took my first dose about an hour ago, and I'm feeling a bit lightheaded and sleepy. Is this normal? Before this happened I was not taking any other medications. I'm a little worried because I have to drive to work tomorrow. Are these side effects I should be concerned about? And if so, how long do they last? This is my first time taking this med, so any advice would be helpful.
