Keeping up with your blood tests

As part of your treatment with this relapsing MS oral medication, your healthcare provider will keep a close eye on your lymphocyte count and liver function. Lymphocytes are a type of white blood cell. Your healthcare provider will do blood tests to check your white blood cell count as follows:

  • Before you start treatment
  • Six months after you start treatment
  • Six to 12 months thereafter and as needed

If your lymphocytes fall below a certain level for more than 6 months, your healthcare provider may talk to you about interrupting your treatment.

To check your liver function your healthcare provider will do blood tests as follows:

  • Before you start treatment
  • As needed during treatment

Ask your healthcare provider when you should come in for your next blood test.

How does your TECFIDERA arrive?

TECFIDERA is not available at your local pharmacy or standard mail order service, but you don’t have to go out of your way to get it. Your healthcare provider's office and your insurance company will work together to order it from a specialty pharmacy. This type of pharmacy carries medicines that need special handling or storage. Once an order is placed on your behalf, it is shipped directly to you.
