Discussions that mention clindamycin

Allergies board

I had my wisdom teeth out last week, and the oral surgeon prescribed an antibiotic (clindamycin) to prevent infection. I had been taking it for 4 days when I developed a rash on my stomach. I ended up taking the antibiotic for another full day before stopping. My regular doctor says that it is most likely a reaction to the clindamycin that caused the rash. My whole stomach is bright red, itchy, and has a few welts. It is also on my sides and a little under my upper arm and my upper chest. My question is: how long should I expect the rash to last? My doctor prescribed an antihistamine to help with the itching (which it has), but it's been 3 days and I still have the rash. Any help would be appreciated!
