It is generally considered safe to drink alcohol in moderation while taking naproxen, but caution is advised because combining alcohol with naproxen can increase the risk of stomach irritation, ulcers, and gastrointestinal bleeding. Both naproxen and alcohol can irritate the stomach lining, so drinking alcohol while on naproxen may worsen side effects like nausea, stomach pain, and heartburn. To minimize risks, it is recommended to limit alcohol consumption to moderate levels (around 14 units per week for adults) and ideally wait 12 to 17 hours after taking naproxen before drinking alcohol. People with a history of stomach problems or heavy alcohol use should consult a healthcare provider before combining naproxen and alcohol. In summary, moderate alcohol consumption is generally allowed but should be done cautiously to avoid gastrointestinal and other side effects, and medical advice is recommended for personalized guidance.
