Frequently asked questions
How quickly does amoxicillin work?
Many feel better in 2–3 days, but finish the whole course to fully clear the infection and limit resistance.
Can I drink alcohol with amoxicillin?
A small amount is not usually dangerous, but it can worsen side effects and slow recovery.
