SAFETY SUMMARY

Warnings - FORTEO may cause serious side effects, including:

Allergic (hypersensitivity) reactions, including anaphylaxis. Stop using FORTEO and get medical help right away if you have any of the following symptoms of an allergic reaction:

  • swelling of your face, lips, mouth, or tongue
  • breathing problems
  • fainting, dizziness, feeling lightheaded (low blood pressure)
  • fast heartbeat
  • itching
  • rash
  • hives

Do not use FORTEO if you have had a severe allergic reaction to teriparatide or any of the ingredients in FORTEO. Ask your healthcare provider if you are not sure.

Possible bone cancer (osteosarcoma): During drug testing, the medicine in FORTEO caused some rats to develop a bone cancer called osteosarcoma. Studies in people have not shown that FORTEO increases your chance of getting osteosarcoma. There is little information about the chance of getting osteosarcoma in patients using FORTEO beyond 2 years. Tell your healthcare provider right away if you have pain in your bones, pain in any areas of your body that does not go away, or any new or unusual lumps or swelling under your skin that is tender to touch.

Increased calcium in your blood: Tell your healthcare provider if you have nausea, vomiting, constipation, low energy, or muscle weakness. These may be signs there is too much calcium in your blood.

Worsening of your kidney stones: If you have or have had kidney stones, your healthcare provider may check the calcium levels in your urine while you use FORTEO to see if there is worsening of this condition.

Decrease in blood pressure when you change positions: Some people may feel dizzy, get a fast heartbeat, or feel light-headed right after the first few doses of FORTEO. This usually happens within 4 hours of taking FORTEO and goes away within a few hours. For the first few doses, give your injections of FORTEO in a place where you can sit or lie down right away if you get these symptoms. If your symptoms get worse or do not go away, contact your healthcare provider before you continue using FORTEO.

How to take

  • Use FORTEO exactly as your healthcare provider tells you to. Your healthcare provider will tell you how much FORTEO to use and when to use it.

  • Inject FORTEO 1 time each day in your thigh or abdomen (lower stomach area). Do not inject into a vein or a muscle. Talk to a healthcare provider about how to rotate injection sites.

  • Do not take more than 1 injection in the same day. Do not share your FORTEO delivery device with other people.
  • You should not use FORTEO for more than 2 years over your lifetime unless your healthcare provider finds that you need longer treatment because you have a high chance of breaking your bones.
  • Store FORTEO in the refrigerator between 36°F to 46°F (2°C to 8°C) until ready to use. Inject FORTEO right away after you take the delivery device out of the refrigerator. Do not freeze FORTEO.
