Taking 150 mg tab every six hours for removal of 16 teeth in preparation for a full upper denture and partial lower denture. Three weeks prior to getting dentures, I started taking Erythromycin for an infected lower back tooth that was extracted.
If I Am Allergic To Penicillin, Am I Also Allergic To Clindamycin?

Clindamycin is considered safe for use in patients with a penicillin allergy.
Penicillin belongs to a class of drugs called beta-lactam antibiotics. These drugs include penicillin and amoxicillin. They are used to treat many common bacterial infections including skin, ear, sinus and upper respiratory infections.
Penicillin allergy is an overreaction by your immune system to penicillin and other antibiotics in the beta-lactam family and closely related antibiotics, including some cephalosporins.
