Palopegteriparatide Injection

Palopegteriparatide is used for the treatment of hypoparathyrodism in adults. Palopegteriparatide is in a class of medications called parathyroid agents. It works by increasing the amount of parathyroid hormone to maintain appropriate calcium levels in the body.

Palopegteriparatide comes as an injection to inject subcutaneously (under the skin). It is usually given once daily in the evening when you are sitting or lying down. Give the injection into your abdomen (stomach area) or the front of your thigh and be sure to change the place where you give the injection each day. Only give the injection when you can sit or lie down. Use palopegteriparatide at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use palopegteriparatide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on a dose of palopegteriparatide and gradually increase or decrease your dose based on your laboratory results and symptoms.

Ask your pharmacist or doctor for a copy of the manufacturer's information (Medication Guide) for the patient.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it the refrigerator until you first use it. After first use, you may store it for up to 14 days at room temperature (below 30°C [86°F]). After each use, remove the needle and put the pen cap on to protect from light. Properly dispose of the pen 14 days after your first use.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org
