Teriparatide is given by injection (pre-filled pen) under the subcutaneous (skin) into the thigh or abdomen. The dose for teriparatide is 20mcg once daily up to 2 years. For the first few doses, take the injection where you can sit or lie down as some people may feel dizzy after using Forteo. This usually happens within 4 hours after taking Forteo and goes away within a few hours.
If you forget your dose, inject it as soon as possible on the same day. If it is almost time to inject your next dose, skip the missed dose and resume your usual dosing schedule. Do not have double injections on the same day as it may increase chances of experiencing unwanted side effects. For subsequent doses, go back to the original timing.
Seek medical help nearest to you by visiting the Accident and Emergency Department. Signs and symptoms of overdose may include high blood calcium levels, dizziness, light-headed on standing up. Nausea, vomiting and headache may also occur.
You may be recommended to supplement vitamin D and calcium when you start this medication
During testing, teriparatide used in rats, developed osteosarcoma (bone cancer) with higher doses and longer periods of treatment. Osteosarcoma in human is serious but a very rare cancer. Before you use Forteo, inform your healthcare provider if you have Paget's disease of bone, unexplained elevation of alkaline phosphatase, are a child or young adult whose bones are still growing or have had radiation therapy.
