  • The recommended dose for all FDA approved indications is 20 mcg subcutaneously once a day. F
  • orteo should be administered subcutaneously in either the thigh or stomach area.
  • Forteo pens are preset to deliver 20 mcg of medicine with each injection.
  • The safety and effectiveness of Forteo injection has not been studied beyond 2 years of treatment.


  • Forteo injection should be used cautiously in patients taking digoxin (Lanoxin), a medication used to treat irregular heart rhythms. Forteo increases calcium in the blood and high levels of calcium may increase the risk for digoxin associated side effects.
  • Forteo injection should be used cautiously with other medicines that may increase calcium in the blood.


  • Use of Forteo in pregnant women has not been adequately evaluated. Due to the lack of conclusive safety data, Forteo should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. Forteo injection is classified as FDA pregnancy risk category C. (Adverse effects have been demonstrated in animals, but there is no adequate data in humans.)
  • It is not known if Forteo is excreted in breast milk. As many drugs can enter human milk and have the potential of causing harm to the nursing baby, Forteo should only be used in nursing mothers if clearly needed.
