Clindamycin
"Prescribed after surgery on hand, told to take 1 150mg capsule every 8 hours, well that meaning one right before bed. HORRIBLE IDEA!! I wasn't informed to drink a whole glass of water with or not to lay down up to 30 mins after. So about a week into taking it on my night time one (midnight) took it and went to bed. Woke up with the worlds worst heartburn. So bad I'm asking my doc at next appointment if I can switch scripts."
