Lab Test Schedule

During treatment, your healthcare provider will need you to have several lab tests to check:

  • Your viral load (how much of the virus is in your body)
  • If you have anemia (low red blood cell count)
  • If you have other side effects

Lab tests are important because they help your healthcare provider manage your treatment and assess how long your treatment will be.

Some of these tests should be done before you start treatment and will be done at least at weeks 2, 4, 8, and 12 during INCIVEK Triple Therapy. Your healthcare provider may do earlier and more frequent testing. If your body is not responding to treatment at any point, your healthcare provider will stop your treatment.

Do not stop taking INCIVEK Triple Therapy unless your healthcare provider tells you to. If you think there is a reason to stop taking INCIVEK Triple Therapy, talk with your healthcare provider before doing so. If your healthcare provider tells you to stop taking INCIVEK Triple Therapy, you should not start taking it again, even if the reason for stopping goes away.

Important Safety Information

Serious Side Effects

INCIVEK combination treatment may cause serious side effects, including:

  • Skin rash and serious skin reactions. Skin rashes are common with INCIVEK combination treatment. Sometimes these skin rashes and other skin reactions can become serious, require treatment in a hospital, and may lead to death.
    Call your healthcare provider right away if you develop any skin changes or itching during treatment with INCIVEK.
    Your healthcare provider will decide if your skin changes or any of the following symptoms may be a sign of a serious skin reaction: skin rash with or without itching, fever, swelling of your face, blisters or skin lesions, mouth sores or ulcers, or red or inflamed eyes, like “pink eye” (conjunctivitis). Your healthcare provider will decide if you need treatment for your skin rash or if you need to stop taking INCIVEK or any of your other medicines. Never stop taking INCIVEK combination treatment without talking with your healthcare provider first.
  • Low red blood cell count (anemia) that can be severe. Tell your healthcare provider if you have any of these symptoms of anemia: dizziness, shortness of breath, tiredness, or weakness.
    Your healthcare provider will do blood tests regularly to check your red blood cell count during treatment. If your anemia is severe, your healthcare provider may tell you to stop taking INCIVEK. If this happens, do not start taking it again.
  • Birth defects or death of an unborn baby. INCIVEK combined with peginterferon alfa and ribavirin may cause birth defects or death of your unborn baby. If you or your sexual partner is pregnant or plan to become pregnant, do not take these medicines. You or your partner should not become pregnant while taking INCIVEK with peginterferon alfa and ribavirin and for 6 months after treatment is over.
    If you are a female who can become pregnant, or if you are a female whose male partner takes these medicines:
    • You must have a negative pregnancy test before starting treatment, every month during treatment, and for 6 months after your treatment ends.
    • You must use 2 effective methods of birth control during treatment and for 6 months after all treatment has ended. These 2 forms of birth control should not contain hormones, as these may not work during treatment with INCIVEK. Talk to your healthcare provider about the forms of birth control you should use during this time.
      Two weeks after stopping INCIVEK, you can use a hormonal form of birth control as one of your two forms of birth control.
    • If you or your partner becomes pregnant during treatment or within 6 months after stopping these medicines, tell your healthcare provider right away. Contact the Ribavirin Pregnancy Registry right away by calling 1-800-593-2214. The Registry collects information about what happens to mothers and their babies if the mother takes ribavirin while pregnant.
