Our bottom line

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


  • 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.


  • 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.
