Talimogene Laherparepvec Injection
Actual product appearance may differ slightly.
Why is this medication prescribed?
Talimogene laherparepvec injection is used to treat certain melanoma (a type of skin cancer) tumors that cannot be removed surgically or that came back after being treated with surgery. Talimogene laherparepvec is in a class of medications called oncolytic viruses. It is a weakened and changed form of Herpes Simplex Virus Type I (HSV-1 ‘cold sore virus’) that works by helping to kill cancer cells.
How should this medicine be used?
Talimogene laherparepvec injection comes as a suspension (liquid) to be injected by a doctor or nurse in a medical office. Your doctor will inject the medicine directly into tumors that are on your skin, just below your skin, or in your lymph nodes. You will receive a second treatment 3 weeks after the first treatment, and then every 2 weeks afterwards. The length of treatment depends on how well your tumors respond to treatment. Your doctor may not inject all of the tumors at each visit.
Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with talimogene laherparepvec and each time you receive the injections. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer’s website to obtain the Medication Guide.
