What is Fosamax?

Fosamax is a brand name for the medication alendronate, which belongs to a class of drugs called bisphosphonates. It is primarily used to treat osteoporosis in postmenopausal women and in men. Osteoporosis is a condition where bones become weak and brittle, making them more susceptible to fractures.

Dosage: The typical dose for Fosamax is 70 mg once weekly or 10 mg once daily.

Administration: Fosamax should be taken in the morning, at least 30 minutes before the first food, beverage, or medication of the day, with a full glass of plain water. It's essential to remain upright (sitting, standing, or walking) for at least 30 minutes after taking the medication to prevent esophageal irritation.

Special Instructions: Avoid lying down for at least 30 minutes after taking Fosamax, as this can increase the risk of irritation to the esophagus.



Esophageal Problems: Fosamax can cause irritation or ulceration of the esophagus, especially if not taken properly. It's crucial to follow dosing and administration instructions strictly.

Hypocalcemia: Patients with low blood calcium levels should not take Fosamax unless adequately treated first.

Kidney Function: Individuals with impaired kidney function may require adjustments to their Fosamax dosage.

Pregnancy and Breastfeeding: Fosamax should not be used during pregnancy or breastfeeding unless the potential benefits outweigh the risks.

Side Effects of Fosamax

Common side effects of Fosamax include:

  • Gastrointestinal Issues: Nausea, abdominal pain, heartburn, and difficulty swallowing are common gastrointestinal side effects.
  • Bone, Joint, or Muscle Pain: Some individuals may experience bone, joint, or muscle pain while taking Fosamax.
  • Esophageal Irritation: Irritation or ulceration of the esophagus may occur if Fosamax is not taken with a full glass of water and if patients do not remain upright for 30 minutes after taking it.
  • Headache: Headaches are a relatively common side effect of Fosamax.
  • Dizziness: Some individuals may experience dizziness, particularly when first starting the medication.


How long should I take Fosamax?

Fosamax is often prescribed for several years, but the duration of treatment should be determined by your healthcare provider based on your individual circumstances.

Can I take Fosamax with other medications?

It's essential to discuss all medications and supplements you're taking with your healthcare provider before starting Fosamax, as some drugs may interact with it.

What should I do if I miss a dose of Fosamax?

If you miss a dose, take it as soon as you remember, unless it's almost time for your next dose. In that case, skip the missed dose and resume your regular schedule. Do not take two doses at once to make up for a missed dose.

Can Fosamax prevent all fractures?

While Fosamax can help reduce the risk of fractures, it does not eliminate the risk entirely. It's essential to combine medication with lifestyle changes such as a healthy diet, weight-bearing exercise, and fall prevention strategies for optimal bone health.

Are there any long-term risks associated with Fosamax?

Long-term use of bisphosphonates like Fosamax has been associated with rare but serious side effects such as atypical femur fractures and osteonecrosis of the jaw. However, the overall risk of these complications is low, and the benefits of treatment typically outweigh the risks for most individuals with osteoporosis.

I've been a Canadian Med Center customer for about 6 years now. In all that time there was never once that I considered taking my business elsewhere. They do a great job and the people they contract with are also super.

Always appreciate their prompt service but especially appreciate their hanging in there when there was difficulty getting my doctor to renew my prescription!
