Read the Medication Guide before you start treatment with IMLYGIC and before each IMLYGIC treatment. There may be new information. This Medication Guide does not tell you everything about IMLYGIC. Talk with your healthcare provider if you have any questions about treatment with IMLYGIC.

What is IMLYGIC?

IMLYGIC is a prescription medicine used to treat a type of cancer called melanoma when it is on your skin or in your lymph glands. IMLYGIC is a weakened form of Herpes Simplex Virus Type 1, which is commonly called the cold sore virus. Your healthcare provider will inject IMLYGIC directly into your tumor(s).

IMLYGIC may not help you live longer and may not shrink cancer in your organs (for example, lung or liver).

Who should not get IMLYGIC?

You should not get IMLYGIC if you are pregnant or have a weakened immune system (for example, an immune deficiency, blood or bone marrow cancer, steroid use, or HIV/AIDS).

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. IMLYGIC may affect the way other medicines work and other medicines may affect how IMLYGIC works.

How is IMLYGIC given?

Your healthcare provider will inject IMLYGIC directly into your tumor(s) with a needle and syringe. You will get a second treatment 3 weeks after the first treatment. After that, you will get treatments every 2 weeks for as long as you have tumor(s). You can get treated for 6 months or longer.

Your healthcare provider will decide which tumor(s) to inject and may not inject every one.

It is important to care for the treatment sites properly so that IMLYGIC does not spread to other people. Your healthcare provider will show you how to do this.
