What Happens When You Take Prednisone and Alcohol Together

Both prednisone and alcohol can irritate the stomach lining, and combining them increases the risk of GI bleeding and ulcers. Alcohol can also worsen prednisone's effects on blood sugar, bone density, and immune function. Long-term use of both substances compounds these risks significantly.

How This Interaction Works (Mechanism)

Prednisone reduces the protective prostaglandin and mucus layer in the stomach while alcohol directly irritates and erodes the gastric mucosa through its cytotoxic effects on epithelial cells. Additionally, both prednisone and alcohol independently raise blood glucose levels (prednisone through gluconeogenesis stimulation, alcohol through impaired insulin sensitivity), which can be problematic for diabetic patients or those at risk.

What You Should Do

Limit alcohol consumption while taking prednisone. If you are on a short course (less than 2 weeks), occasional light drinking is unlikely to cause serious problems for most people. For long-term prednisone use, discuss alcohol consumption with your doctor. Avoid drinking on an empty stomach. Watch for signs of stomach bleeding (dark stools, stomach pain, vomiting).
