Brief Answer: they are a different family Detailed Answer: Hi, thanks for using healthcare magic No, azithromycin is in a class of antibiotics called macrolides. Other macrolides are erythromycin and clarithromycin.They have a similar structure which is essentially a large ring (called a macrocyclic lactone ring). The structure and mechanism of action is different compared to penicillins. Macrolides are sometimes used when there is a history of allergy to penicillins. I hope this helps , feel free to ask any additional questions
