Fosamax for Osteopenia

Posted by cwal @cwal, Dec 7, 2025

Has anyone had any major issues or side effects taking Fosamax for Osteopenia? I've reached the point in my osteopenia where I need to start taking something and was wondering how common it was to have problems with the most common one to be prescribed first.

I took Fosamax for three months. At 2 1/2 months, I experienced muscle, jaw and joint pain to the point that I could barely walk. Up until then I was swimming 3 times/week, 45 minutes (nonstop) at a time. The onset was sudden and dramatic and happened after a swimming session when I was walking across the parking lot. My legs turned to jelly and I barely made it my car. Since then, I've had excruciating pain in my arms, hips, back and shoulders. It seems like every injury I've ever had was reignited. I was admitted to the hospital where they run multiple tests, but found nothing that was causing these symptoms, I've also had severe vertigo, though unsure if this is Fosamax-related.

Please check with your prescribing MD and find out if these are identified as side effects of Fosamax, or if something else is going on. It certainly sounds like medical expertise is needed.

Good luck to you and I hope you get some answers, and feel better!

Yes, and the rest of us on the fence about taking these drugs or are taking them would like to clarify for our information

Thanks. I am under a doctor's care. I've had blood tests, EKG, MRI, EEG and other tests. I am continuing to pursue the cause, though various sites, including the Mayo Clinic list joint and muscle pain as side effects of Fosamax. Not ready to accept that that is the definite answer to what's going on,

I was on Fosamax for 3 months. I suffered increasingly bad leg cramps and leg / foot pain. Eventually, I could barely stand because my feet hurt so much. I stopped the medication and gradually the symptoms decreased and went away. My podiatrist said she sees many patients with leg / feet issues caused by bone density drugs.

Fosamax is a waste and too many side effects.
Basically take necrotic bone and glues it together.. Best solution is bone formula with boron and
other nutrients that make up the bone.

I took fosomax/alendronate for 5 years. No noticeable side effects.
Nor were there noticeable side effects with forteo, evenity or Prolia.
Please send a link to any credible research you have used for these assertions.
Certainly osteonecrosis can occur with fosomax or Prolia but it is rare.
Have you or someone you care about had this rare side effect?

Good for you for wanting to know what the effects are from the drugs you take. I try and do the same, as I have been unpleasantly surprised in the past when a physician didn't tell me some of the side effects for some of my meds.

My suggestion to all is to do an internet search, or better, use one of the AI chatbots to come up with a list of known side effects for a drug(s). AI will even give you a list of questions to ask your Dr if you request that. Very handy.

Do keep in mind that AI does NOT substitute for good, firsthand medical advice. It can be useful, but please use with caution and question any results with your Dr.

That's very interesting, thank you chicabow,

Yikes those are some scary side effects from Fosamax.

Yeah simply making weak bones "stronger" by gluing them together hardly seems like a good solution. There are other drugs and infusions one can take to treat osteopenia. The best thing is to get a referral from your PCP to a specialist. I agree that it is better to build bones using natural methods than simply hardening the existing bones.

Bones are living tissue with a blood supply. I would not mess with that.

Thanks gravity, excellent questions. All drugs have some side effects. The question to ask a Dr is specific side effects and the likelihood they will happen.

Drs prescribe drugs because they feel the benefits outweigh the risks. We need to follow that method when considering any OTC treatment.
