Frequently Asked Questions
Can I drink alcohol while taking amoxicillin?
Yes, but not recommended. Alcohol does not interact with amoxicillin, and drinking alcohol does not reduce the effectiveness of the antibiotic. However, alcohol can suppress your immune system, making you more susceptible to infections and harder to recover from.
Will Amoxicillin Affect Contraception?
Yes, amoxicillin and other antibiotics can make some oral contraceptives less effective. Women taking estrogen/progesterone birth control pills should use backup protection (such as condoms) while taking antibiotics and continue until the end of the cycle.
