Tegsedi

Uses

TEGSEDI is a medicine used to treat the polyneuropathy of hereditary transthyretin-mediated (hATTR) amyloidosis in adults. It is not known if TEGSEDI is safe and effective in children.

Side Effects Of Tegsedi

TEGSEDI can cause serious side effects, including:

low platelet counts (thrombocytopenia). TEGSEDI may cause the number of platelets in your blood to be reduced.

This is a common side effect. When your platelet count is too low, your body cannot form clots. You could have serious bleeding that could lead to death. Call your healthcare provider immediately if you have:

    • unusual bruising or a rash of tiny reddish-purple spots, often on the lower legs
    • bleeding from skin cuts that do not stop or oozes
    • bleeding from your gums or nose
    • blood in your urine or stools
    • bleeding into the whites of your eyes
    • sudden severe headaches or neck stiffness
    • vomiting or coughing up blood
    • abnormal or heavy periods (menstrual bleeding)

• kidney inflammation (glomerulonephritis). Your kidneys may stop working properly. Glomerulonephritis can lead to severe kidney damage and kidney failure that needs dialysis. Call your healthcare provider immediately if you have:

    • puffiness or swelling in your face, feet, or hands
    • new-onset or worsening shortness of breath and coughing
    • blood in your urine or brown urine
    • foamy urine (proteinuria)
    • passed less urine than usual

Your healthcare provider will do laboratory tests to check your platelet count and kidneys before you start TEGSEDI and while you are using it. Your healthcare provider should also do laboratory tests for 8 weeks after you stop TEGSEDI. It is important that you make sure you get these laboratory tests done.

• Because of the risk of serious bleeding caused by low platelet counts and because of the risk of kidney problems, TEGSEDI is available only through a restricted program called the TEGSEDI Risk Evaluation and Mitigation (REMS) Program.

    • Before you begin using TEGSEDI, you must enroll in the TEGSEDI REMS Program. Talk to your healthcare provider about how to enroll in the TEGSEDI REMS Program.
    • You must agree to get your laboratory testing done while you are in the TEGSEDI REMS Program.
    • You can only get TEGSEDI from a certified pharmacy that participates in the TEGSEDI REMS Program. Your healthcare provider can give you information on how to find a certified pharmacy.

Warnings & Precautions

Do not use if you have:

• a platelet count that is low.

• had kidney inflammation (glomerulonephritis) caused by TEGSEDI.

• had an allergic reaction to inotersen or any of the ingredients in TEGSEDI. See the end of this Medication Guide for a complete list of ingredients.

Before you start using TEGSEDI, tell your healthcare provider about all your medical conditions, including if you:

• have or had bleeding problems

• have or had kidney problems

• have received a liver transplant

• are pregnant or plan to become pregnant. It is not known if it can harm your unborn baby.

• There is a registry for women who become pregnant during treatment with TEGSEDI. If you become pregnant while taking it, talk to your healthcare provider about registering with the TEGSEDI Pregnancy Exposure Registry.

The purpose of this registry is to collect information about your health and your baby’s health.
