Can You Take Azithromycin with Alcohol?
Last reviewed: · Source: US FDA drug label database
Avoid alcohol with azithromycin — alcohol impairs immunity and recovery from infection, and may worsen stomach upset.
Is it safe to take Azithromycin with Alcohol?
Azithromycin is a macrolide antibiotic used for chest infections, STIs, and other bacterial infections. There is no severe direct interaction with alcohol, but alcohol impairs immune function, worsens GI side effects, and is counterproductive when your body is fighting infection. Azithromycin can also affect heart rhythm (QT prolongation), and alcohol may compound this at higher doses.
How do Azithromycin and Alcohol interact?
Azithromycin is widely distributed, with long tissue half-life (68 hours). Alcohol does not significantly alter azithromycin pharmacokinetics. The QT prolongation concern is additive: azithromycin mildly prolongs QT interval, and heavy alcohol use can also affect cardiac conduction in susceptible individuals.

Who should be careful?
Those with pre-existing cardiac conditions or taking other QT-prolonging medications. Those with liver disease.
What if I've already taken Azithromycin and Alcohol?

Frequently Asked Questions
Can I drink on azithromycin?
Best avoided. Alcohol impairs immunity and may worsen stomach upset. There is also a minor cardiac rhythm concern with heavy alcohol use given azithromycin's QT effects.
Does azithromycin affect heart rhythm?
Yes, azithromycin can mildly prolong the QT interval. This is generally not a concern in healthy individuals taking standard doses, but combining with alcohol (which also affects cardiac conduction in heavy use) adds to the risk.
Can I have a glass of wine while on azithromycin?
One glass is unlikely to cause serious harm for most healthy people, but it is better to avoid alcohol until your infection has resolved.
How long does azithromycin stay in your system?
Azithromycin has a very long half-life of about 68 hours. A standard 3-day or 5-day course means the drug remains in your system for about 2 weeks after the last dose.
