Clindamycin
"Dr gave me 300mg 4 times a day for what they think is infection in my foot after a drawer fell on my foot and had fluid on top of foot with swelling. After 3rd dose throat was swollen. Couldn't swallow made the left side of my chest hurt so bad it felt like a heart attack. I was itching so bad. I was so thirsty. I went to ER, Dr said he had never heard of anyone having a reaction to that med. Gave me a shot of benadryl it helped. It wore off and everything happened again. Days later my stomach is cramping. I have been drinking pedalite & Gatorade. Still feel thirsty. I am allergic to penicillin & bactrim so Dr thought this would be a good one. It is not. This is wicked stuff. NEVER EVER will I take again"
