How should I use parathyroid hormone?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Parathyroid hormone is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
Use only the cartridges and injection pen provided with the medicine. Do not use a syringe to inject parathyroid hormone.
Do not shake the cartridge or you may ruin the medicine. Prepare an injection only when you are ready to give it. Do not use if the medicine has changed colors. Call your pharmacist for new medicine.
You will need frequent medical tests while using this medicine and for a short time after your last dose.
Do not change your dose or stop using parathyroid hormone without your doctor's advice. You could have dangerously low calcium levels if you stop using this medicine suddenly.
Store in the refrigerator, do not freeze. Protect from heat and light.
Each Natpara cartridge contains enough medicine for 14 separate injections. Throw the cartridge away after 14 uses, even if there is still medicine left inside.
Do not throw away the injection pen. It can be used for up to 2 years if you change the cartridge every 14 days.
