If your doctor prescribed alendronate, you probably want clear, no-nonsense info: what it does, how to take it, and how to stay safe. Alendronate is a bisphosphonate that slows bone breakdown and helps prevent fractures in people with osteoporosis. It’s effective, but how you use it makes a big difference in both benefit and side effects.
Take alendronate first thing in the morning, right after you get up. Swallow the tablet with a full glass (200–240 ml) of plain water. Don’t chew or suck the tablet. Stay sitting or standing for at least 30 minutes after taking it—lying down raises the risk of irritation to your esophagus.
Wait at least 30 minutes before eating, drinking anything other than plain water, or taking other meds, especially calcium, magnesium, iron supplements, or antacids. Those products bind with alendronate and can make it less effective. Many people use a weekly dose (common is 70 mg once weekly) or a daily dose (commonly 5–10 mg daily) depending on the prescription—follow your doctor’s instructions exactly.
Common side effects are stomach upset, heartburn, and mild muscle or joint pain. If you get new or worsening chest pain, severe heartburn, or trouble swallowing, stop the drug and call your doctor—these can be signs of esophageal injury. Rare but serious risks include low blood calcium, atypical femur fractures (thigh bone), and osteonecrosis of the jaw, especially after dental surgery. Because of jaw risk, tell your dentist you’re on alendronate before any oral surgery.
Don’t take alendronate if you can’t sit upright for 30 minutes, have active esophageal problems, or have very low blood calcium. People with severe kidney problems may need a different option—your doctor will check kidney function first. Also avoid pregnancy and breastfeeding while on alendronate; discuss family planning with your provider.
Drug interactions matter. Calcium, antacids, iron, and magnesium reduce absorption. NSAIDs can increase risk of stomach irritation. Always review your full medication list with the prescriber or pharmacist.
Storage and missed doses: keep tablets in a dry place at room temperature, away from children. If you miss a weekly dose and remember the same day, take it; otherwise skip and take the next scheduled dose—do not double up. For daily dosing, if you miss one day, take it the next morning.
