Dactinomycin comes as a powder to be mixed with liquid to be injected intravenously (into a vein) by a doctor or nurse in a medical facility. The length of treatment depends on the type of cancer you have, the types of other drugs you are taking, and how well your body responds to treatment. Your doctor may need to stop or delay your treatment if you experience certain side effects. Dactinomycin may also be injected by a doctor directly into a specific part of the body or the organ to treat the area where a tumor is located.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests to check your body’s response to dactinomycin.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
