Clindamycin
"I was prescribed this medication to treat a serious glandular infection in my neck. An allergy to penicillin made Clindamycin the most effective choice, despite the potential of fairly serious side effects. I followed the dosing instructions, making sure that I took it with something in my stomach (I ate a 1/2 portion of oatmeal porridge 30 minutes before each pill); walked around for a 1/2 hour after taking it; had either an active culture yogurt drink or 1/2 cup of plain yogurt 2 hours after each dose to help restore the bacteria in my gut. I only had minor loose bowel movements at about day 4 and had excellent results in combating the infection. "
