What to know about SELZENTRY

While you’re learning whether treatment with SELZENTRY along with other HIV-1 medicines might be an option for you or your child, it’s important to keep in mind its risks and side effects. Below are some key things you may want to know.

These are not all the risks and side effects of SELZENTRY, and this information does not replace talking with your healthcare provider about your medical condition or treatment. For more information, talk to your healthcare provider and refer to the Medication Guide for SELZENTRY.

What is the most important information I should know about SELZENTRY?

SELZENTRY can cause serious side effects including serious liver problems (liver toxicity). An allergic reaction may happen before liver problems occur. Stop taking SELZENTRY and call your healthcare provider right away if you get any of the following symptoms:

  • an itchy rash on your body (allergic reaction)
  • your skin or the white part of your eyes turns yellow (jaundice)
  • dark or “tea-colored” urine
  • vomiting
  • pain, aching, or tenderness on the right side of your stomach area

Your healthcare provider will do blood tests to check your liver before you begin treatment with SELZENTRY and as needed during treatment, and if you get a severe rash, signs and symptoms of liver problems, or an allergic reaction during treatment with SELZENTRY.

Who should not take SELZENTRY?

Do not take SELZENTRY if you have severe kidney problems or are on hemodialysis and are also taking certain other medications.

What should I tell my healthcare provider before taking SELZENTRY?

Before you take SELZENTRY, tell your healthcare provider if you:

  • have or have had liver problems including hepatitis B or C virus infection.
  • have heart problems.
  • have kidney problems.
  • have low blood pressure or take medicines to lower blood pressure.
  • are pregnant or plan to become pregnant. It is not known if SELZENTRY may harm your unborn baby.
  • are breastfeeding or plan to breastfeed. Do not breastfeed if you take SELZENTRY. You should not breastfeed if you have HIV-1 because of the risk of passing HIV-1 to your baby.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Some medicines may interact with SELZENTRY. Keep a list of your medicines to show your healthcare provider and pharmacist.

  • You can ask your healthcare provider or pharmacist for a list of medicines that interact with SELZENTRY. Do not start taking a new medicine without telling your healthcare provider. Your healthcare provider can tell you if it is safe to take SELZENTRY with other medicines.  Your healthcare provider may need to change your dose of SELZENTRY when you take it with certain medicines.
  • You should not take SELZENTRY if you also take St. John’s wort (Hypercium perforatum).

What are the possible side effects of SELZENTRY?

  • SELZENTRY can cause serious side effects including:
  • See “What is the most important information I should know about SELZENTRY?”
  • Serious skin rash and allergic reactions. Severe and potentially life-threatening skin reactions and allergic reactions have been reported in some patients taking SELZENTRY. If you develop a rash with any of the following symptoms, stop using SELZENTRY and contact your doctor right away:
    • fever
    • generally ill feeling

Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider right away if you develop new symptoms after you start taking SELZENTRY.
  • Possible chance of infection or cancer. SELZENTRY affects other immune system cells and therefore may possibly increase your chance for getting other infections or cancer.
