Is long-term Alendronate safe, and is a break needed?

Question

Hello doctor,

I am 65 and was recently diagnosed with osteoporosis. My DEXA scan showed a T-score of -2.9 in my spine and -2.6 in my hip. I have started taking Alendronate, but am concerned about rare side effects such as osteonecrosis of the jaw and atypical femur fractures. Is long-term use of this medication considered safe? When should I consider taking a “drug holiday”?

Should I be evaluated for possible secondary causes, like thyroid or parathyroid disorders? My vitamin D levels are low. How much should I be taking, and should I also supplement with calcium?

Can exercise still help strengthen my bones at my age, or is it risky? Lastly, do different medications vary in effectiveness depending on whether the bone loss is more severe in the spine versus the hip? Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

1. Medication safety and long-term use:

Alendronate, a commonly prescribed bisphosphonate, is effective in reducing fracture risk in osteoporosis (a condition where bones become weak and brittle, increasing the risk of fractures).

While rare, long-term use can be associated with side effects like jaw osteonecrosis and atypical femur fractures. However, for most patients, the benefits of fracture prevention outweigh these risks.

2. Drug holiday:

A “drug holiday” may be considered after three to five years of treatment, depending on your current fracture risk. Your doctor will reassess your bone health and decide whether to pause or continue the medication.

3. Secondary causes:

It is important to evaluate for secondary causes of osteoporosis, such as thyroid or parathyroid disorders (hormonal imbalances that can affect bone health by disrupting calcium and metabolism regulation), which can contribute to bone loss.

4. Vitamin D and calcium:

Vitamin D supplementation is essential for bone health. Older adults are usually advised to take 600 to 800 IU (international units) daily, although individual needs may vary. Ensure you are also getting enough calcium, ideally through diet, with a total daily intake of around 1000 to 1200 mg. Avoid going over 1200 mg/day to reduce the risk of side effects.

5. Next steps:

Continue regular monitoring of your bone density and fracture risk with your healthcare provider. This will help guide future treatment and ensure the best outcomes for your bone health.

I hope this helps.
