Cosmegen

Cosmegen is a prescription medication that is used in various types of cancer chemotherapy. Cosmegen belongs to a group of antibiotics called actinomycins. It is thought to work by binding to the DNA of cancer cells and inhibiting RNA synthesis, causing the cancer cells to die.  

This medication comes in liquid form and is infused into a vein (IV) by a healthcare provider at a hospital or other medical facility. How often you will receive Cosmegen depends upon the condition being treated.

Common side effects include hair loss, hives, and difficulty breathing. Cosmegen may lower blood cells involved in fight infection; therefore, you should avoid people with known infections.

Cosmegen is a prescription antibiotic that is only used in cancer chemotherapy. It is used alone, or in combination with other medications, surgery, and/or radiation therapy to treat various types of cancer including:

• Wilm's tumor (kidney cancer usually occurring in children)
• rhabdomyosarcoma (cancer of the connective tissues and muscle) in children
• testicular cancer
• Ewing's sarcoma (cancer in bones or soft tissues)
• gestational trophoblastic tumors (tumor that forms inside a woman's uterus while pregnant)
• solid tumors

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

The Cosmegen dose your doctor recommends will be determined by the type of cancer you have, your height and weight, other medicines and treatments you are receiving, as well as other factors.
