Alendronate

What Is Alendronate?

Alendronate is a prescription medication used to prevent and treat osteoporosis and certain other bone disorders. It belongs to a group of medications called bisphosphonates, which work by slowing bone breakdown, helping maintain bone density, and reducing the risk of fractures.

Alendronate is commonly prescribed for postmenopausal osteoporosis, osteoporosis in men, and bone loss related to long-term corticosteroid use.

Why Alendronate Matters

As people age, bones naturally lose density and become more fragile. Alendronate helps strengthen bones, lowering the risk of fractures, particularly in the spine and hips, which are common and potentially serious injuries among older adults.

Common Uses of Alendronate

  • Postmenopausal osteoporosis
  • Osteoporosis in men
  • Glucocorticoid-induced osteoporosis
  • Paget’s disease of bone

Common Side Effects

  • Heartburn
  • Stomach pain
  • Acid reflux
  • Nausea
  • Difficulty swallowing
  • Muscle or joint pain
  • Constipation
  • Diarrhea

How Should Alendronate Be Taken?

Alendronate is usually taken first thing in the morning with a full glass of plain water before eating or drinking anything else. After taking the medication, individuals should remain sitting or standing upright for at least 30 minutes and avoid eating, drinking, or taking other medications during that time unless instructed otherwise by their healthcare provider.

How Home Care Can Help

Home care professionals help individuals remember to take alendronate correctly, encourage adequate calcium and vitamin D intake when recommended, promote fall prevention, assist with mobility, and monitor for possible medication side effects.

Home Care Tip

Never lie down immediately after taking alendronate. Remaining upright helps reduce the risk of irritation or injury to the esophagus.
