Why is this medication prescribed?
Tafamidis is used to treat transthyretin amyloid cardiomyopathy (ATTR-CM; a condition in which a protein (transthyretin) builds up in the wall of the heart making it thicker which makes it difficult for the heart to pump blood adequately). Tafamidis is in a class of medications called transthyretin stabilizers. It works by preventing the formation of transthyretin protein deposits in the heart.
How should this medicine be used?
Tafamidis comes as a capsule to take by mouth. It is usually taken with or without food once a day. If you are taking tafamidis (Vyndamax), it is usually given as 1 capsule once a day. If you are taking tafamidis (Vyndaqel), it is usually given as 4 capsules once a day. Take tafamidis 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. Take tafamidis exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the capsules whole; do not split, chew, or crush them.
Tafamidis controls ATTR-CM but does not cure it. Continue to take tafamidis even if you feel well. Do not stop taking tafamidis without talking to your doctor.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

What side effects can this medication cause?
Tafamidis may cause side effects. Call your doctor if you have any unusual problems while taking this medication.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
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).
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
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

What other information should I know?

You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
