Alcohol and Fosamax

Fosamax isn’t known to interact with alcohol. However,  it’s possible that drinking large amounts of alcohol over time can increase your risk of osteoporosis. If you already have osteoporosis, drinking alcohol may make your condition worse. Alcohol can change the way that your body absorbs calcium and vitamin D which can worsen your symptoms of osteoporosis.

This medicine can irritate your Esophagus. Call your doctor right away if you think this medicine has started to damage your esophagus.
