Forteo Overview

Updated: 

Forteo is a prescription medication used to treat both men and postmenopausal women with osteoporosis who are at high risk for having broken bones. Forteo is a synthetic hormone that is similar to the one the body makes naturally (parathyroid hormone). It works by causing the body to build new bone and increase bone strength by regulating calcium and phosphate.

Forteo comes in an injectable form that is given once daily. It is injected just under the skin of the stomach area or thigh.

Common side effects include nausea, joint aches, and pain.

Your healthcare provider may take samples of blood and urine during treatment to check your response to Forteo. Also, your healthcare provider may ask you to have follow-up tests of bone mineral density.

Forteo Interactions

Tell your healthcare provider about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. Your healthcare provider needs this information to help keep you from taking Forteo with other medicines that may harm you. Especially tell your doctor if you take medicines that contain digoxin (Digoxin, Lanoxicaps, Lanoxin).

Forteo Precautions

  • During the drug testing process, the medicine in Forteo caused some rats to develop a bone cancer called osteosarcoma. In people, osteosarcoma is a serious but rare cancer. Osteosarcoma has been reported rarely in people who took Forteo. It is not known if people who take Forteo have a higher chance of getting osteosarcoma.
  • You should not take Forteo for more than 2 years over your lifetime.
  • There is a voluntary Patient Registry for people who take Forteo. The purpose of the registry is to collect information about the possible risk of osteosarcoma in people who take Forteo.

Do not use Forteo if you are allergic to any of the ingredients in Forteo.

Forteo Food Interactions

Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of Forteo there are no specific foods that you must exclude from your diet when receiving Forteo.

Forteo and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Forteo and Lactation

Tell your doctor if you are breastfeeding or planning to breastfeed. It is not known if Forteo is excreted in human breast milk or if it will harm your nursing baby.

Forteo Usage

  • Inject Forteo one time each day in your thigh or abdomen (lower stomach area). Talk to a healthcare provider about how to rotate injection sites.
  • Before you try to inject Forteo yourself, a healthcare provider should teach you how to use the Forteo delivery device to give your injection the right way.
  • You can take Forteo with or without food or drink.
  • The Forteo delivery device has enough medicine for 28 days. It is set to give a 20 microgram dose of medicine each day. Do not inject all the medicine in the Forteo delivery device at any one time.
  • Do not transfer the medicine from the Forteo delivery device to a syringe. This can result in taking the wrong dose of Forteo. If you do not have pen needles to use with your Forteo delivery device, talk with your healthcare provider.
  • Forteo should look clear and colorless. Do not use Forteo if it has particles in it, or if it is cloudy or colored.
  • Inject Forteo right away after you take the delivery device out of the refrigerator.
  • After each use, safely remove the needle, recap the delivery device, and put it back in the refrigerator right away.
  • You can take Forteo at any time of the day. To help you remember to take Forteo, take it at about the same time each day.
  • If you forget or can not take Forteo at your usual time, take it as soon as you can on that day. Do not take more than one injection in the same day.
  • If you take more Forteo than prescribed, call your healthcare provider. If you take too much Forteo, you may have nausea, vomiting, weakness or dizziness.
  • Follow your healthcare provider's instructions about other ways you can help your osteoporosis, such as exercise, diet, and reducing or stopping your use of tobacco and alcohol. If your healthcare provider recommends calcium and vitamin D supplements, you can take them at the same time you take Forteo.

Forteo Dosage

The recommended Forteo dose is 20 mcg given subcutaneously once a day. Your doctor will determine the best dose for you. Take Forteo exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

Forteo Overdose

If you take too much Forteo, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

If Forteo is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.

Forteo FDA Warning

WARNING: POTENTIAL RISK OF OSTEOSARCOMA

In male and female rats, Forteo caused an increase in the incidence of osteosarcoma (a malignant bone tumor) that was dependent on dose and treatment duration. The effect was observed at systemic exposures to Forteo ranging from 3 to 60 times the exposure in humans given a 20-mcg dose. Because of the uncertain relevance of the rat osteosarcoma finding to humans, prescribe Forteo  only for patients for whom the potential benefits are considered to outweigh the potential risk. Forteo should not be prescribed for patients who are at increased baseline risk for osteosarcoma (including those with Paget's disease of bone or unexplained elevations of alkaline phosphatase, pediatric and young adult patients with open epiphyses, or prior external beam or implant radiation therapy involving the skeleton) [see Warnings and Precautions, Adverse Reactions, and Nonclinical Toxicology.
