Can You Take Lansoprazole with Alcohol?
Last reviewed: · Source: US FDA drug label database
Avoid alcohol with lansoprazole — alcohol irritates the stomach you are trying to heal and may reduce the effectiveness of your treatment.
Is it safe to take Lansoprazole with Alcohol?
Lansoprazole is a proton pump inhibitor (PPI) taken to reduce stomach acid and treat conditions like GORD, ulcers, and gastritis. Alcohol increases stomach acid and directly irritates the gastric lining — the opposite of what lansoprazole is trying to achieve. Regular alcohol use while on lansoprazole can significantly reduce treatment effectiveness and prolong healing.
How do Lansoprazole and Alcohol interact?
Lansoprazole irreversibly inhibits the H+/K+-ATPase proton pump, reducing acid secretion. Alcohol stimulates gastrin release, increasing acid production, and directly damages the gastric mucosa. Together, alcohol counteracts the gastroprotective effect of lansoprazole. Lansoprazole is metabolised by CYP2C19 and CYP3A4; alcohol may affect these enzymes to a minor degree.

Frequently Asked Questions
Can I drink alcohol on lansoprazole?
Alcohol works against lansoprazole's purpose by increasing stomach acid and irritating the lining. Avoid or minimise alcohol for best treatment outcomes.
Will alcohol stop lansoprazole working?
Regular heavy drinking can significantly reduce lansoprazole's effectiveness and slow healing of the stomach condition you are treating.
Can I drink if I take lansoprazole to protect my stomach?
Lansoprazole may provide some protection, but it is not designed to counteract alcohol-related damage. Reducing alcohol is the most effective way to protect your stomach.
How long do I need to be on lansoprazole to drink again?
This depends on the condition being treated. Speak to your GP about when it is appropriate to reintroduce alcohol into your diet.
