4.1/ 7 average rating with 39 reviewsforReclast
Prevents bone loss.

Forteo (Teriparatide) is a good second-choice medication to treat bone loss, but it's only available as an injectable.

  • Available in generic.
  • Depending on what you're using it for, you may only need to take it as a one-time dose, or every 1 to 2 years.
  • If you're unable to use bisphosphonates or are still having fractures despite being on other medications, Forteo (Teriparatide) can be a good alternative.
  • You can start using Forteo (Teriparatide) as soon as you stop using bisphosphonates.
  • You have to go to your doctor's office or an infusion center to get each dose by IV infusion.
  • It can't be used if you have really poor kidney function.
  • Joint pain and muscle pain are common side effects after the infusion.
  • Only available as a brand medication, so it can be expensive.
  • You have to inject this every day, so it may not be a good option if you don't like needles.
  • Shouldn't take this longer than 18 to 24 months since it can increase the risk of bone cancers.
