Alendronate (Alendronate sodium) — Uses, Dosage, Side Effects & Safety
Drug class: Bisphosphonate
Overview
Alendronate is a medication used to treat and prevent osteoporosis in postmenopausal women and men, as well as to treat osteoporosis caused by steroid use and Paget’s disease of bone. It works by slowing down the process that leads to bone loss, helping to maintain or increase bone density and reduce the risk of fractures. Alendronate belongs to a class of drugs called bisphosphonates. It binds to bone and inhibits the activity of cells that break down bone (osteoclasts), helping to keep bones strong. Patients should take alendronate exactly as prescribed, usually once weekly or daily, and follow special instructions to reduce the risk of stomach or esophagus irritation. Key points: Take alendronate first thing in the morning with a full glass of water, remain upright for at least 30 minutes after taking it, and avoid eating or drinking anything else during this time. This helps the medicine work better and reduces the risk of side effects.
