This medication is given by injection into your tumor(s) by a health care professional. It is given as directed by your doctor, usually every 2 weeks. However, your second treatment should be 3 weeks after your first treatment.

The dosage is based on your medical condition and response to treatment.

After getting this medication, you may be able to make others sick with the cold sore virus. To prevent the spread of infection, do not touch or scratch the injection site(s). Keep the injection site(s) covered with airtight and watertight dressing(s) for at least 1 week after each treatment. If the injection site is still oozing or weeping after 1 week, you will need to keep it covered for longer. Ask your doctor for more details. If the dressing comes loose or falls off, replace it right away with a clean dressing. Always wear gloves when changing the dressing. Throw away all used dressings and medical supplies in a sealed plastic bag.

Since you may be able to make others sick with the cold sore virus, people close to you (such as household members, caregivers, sexual partners) should not touch your injection site(s), dressing(s), and body fluids. Caregivers should wear gloves when changing the dressing. Women who are pregnant or who may become pregnant and people with weakened immune systems should not change your dressing or clean your injection site. If someone touches your injection site(s), dressing(s), or body fluids, they should clean the skin that touched you with a disinfectant or soap and water right away. If they have any signs of infection (such as cold sores), they should tell their doctor right away.
