What is Fosamax and what does it do?

Fosamax (alendronate) is a prescription medication that helps to prevent or treat osteoporosis and/or Paget's disease. It is part of a class of drugs called bisphosphonates, which work by slowing down the rate at which bones are broken down and replaced.

How does Medicare cover Fosamax?

Medicare Part D covers Fosamax as a brand-name drug. The cost of the prescription is determined by the quantity and dosage prescribed by your doctor. Your Medicare plan may also require you to meet certain criteria in order to get coverage, such as prior authorization or step therapy. It is important to check with your specific plan for details on coverage and cost-sharing.

Your Medicare Part D plan may also cover generic versions of Fosamax, if available. Check your plan's formulary for a list of drugs covered by your pharmacy plan. Contact your insurer to find out what’s covered in your specific plan.

What are the costs associated with Medicare coverage of Fosamax?

The cost of Fosamax is dependent on your Medicare plan. Generally, Fosamax is usually listed as Tier 1, making it among the cheaper drugs on Medicare. Your out-of-pocket costs may include copayments and coinsurance amounts. These costs might change based on which coverage phase you are in. You may also be responsible for any deductibles or other fees associated with the medication. It is important to check with your insurance provider to determine the total cost of the drug for you.

What are the side effects of taking Fosamax?

The most common side effects of Fosamax include nausea, heartburn, and vomiting. Other possible side effects may include headache, dizziness, constipation, diarrhea, abdominal pain, and muscle or joint pain. If you experience any serious side effects while taking Fosamax, contact your doctor immediately to discuss whether you should stop taking the medication.

It is important to speak with your doctor or pharmacist about any potential side effects before beginning treatment with Fosamax. This will help ensure that you are able to make an informed decision about whether or not this is the right medication for you.

Alternatives to Fosamax

If you are looking for alternatives to Fosamax, there are several other types of medications that can help treat and prevent osteoporosis. These include:

  • Boniva (ibandronate)

  • Actonel (risedronate)

  • Evista (raloxifene)

  • Forteo (teriparatide)

  • Prolia (denosumab).

Your doctor may also recommend lifestyle changes such as exercising regularly, maintaining a healthy diet, and quitting smoking to help prevent bone loss.
