What is Mitapivat?
Mitapivat is used to treat low red blood cell counts caused by hemolytic anemia (early breakdown of red blood cells) in adults with pyruvate kinase deficiency.
Mitapivat may also be used for purposes not listed in this medication guide.
Call your doctor at once if you have jaundice (yellowing of the skin or eyes), dark urine, dizziness, confusion, tiredness, or shortness of breath.
How should I take Mitapivat
Mitapivat comes as a tablet to take by mouth. It is usually taken with or without food 2 times a day. Take mitapivat at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take mitapivat exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets/capsules whole; do not split, chew, or crush them.
Your doctor will probably start you on a low dose of mitapivat and gradually increase your dose, typically every 4 weeks.
Mitapivat controls hemolytic anemia from pyruvate kinase deficiency but does not cure it. Continue to take mitapivat even if you feel well. Do not stop taking mitapivat without talking to your doctor. If you suddenly stop taking mitapivat, you may experience symptoms of acute hemolysis and anemia (yellowing of the skin or whites of the eyes, dark urine, dizziness, confusion, tiredness, difficulty breathing). Your doctor will probably decrease your dose gradually.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Mitapivat tablets should stay in their original blister packaging until ready to 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. http://www.upandaway.org
