Dactinomycin (Intravenous route)
Warnings:Intravenous route(Powder for Solution)
This drug is highly toxic and both powder and solution must be handled and administered with care. Avoid exposure during pregnancy.

If extravasation occurs during intravenous use, severe damage to soft tissues will occur .
Uses of This Medicine:
Dactinomycin injection is used to treat certain types of cancer. This includes cancer of the bones and soft tissue (including muscles and tendons), Wilms' tumor (a cancer of the kidney found primarily in children), tumors in the uterus or womb, and cancer of the testicles.
Dactinomycin interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by dactinomycin, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some effects may not occur for months or years after the medicine is used.
Before you begin treatment with dactinomycin, you and your doctor should talk about the benefits this medicine will do as well as the risks of using it.
This medicine is to be administered only by or under the immediate supervision of your doctor.

If you are taking some of these medicines by mouth, ask your doctor to help you plan a way to remember to take them at the right times.

This medicine is very toxic and can cause severe damage to your skin, eyes, nose, throat, or lungs. The medicine must not come into contact with your skin, eyes, or any other part of your body. If any of the medicine does get in the eyes, wash the eyes with water, normal saline, or a balanced salt irrigating eye solution for at least 15 minutes and check with your doctor right away.

While you are being treated with dactinomycin, and after you stop treatment with it, do not have any live vaccines without your doctor's approval. Dactinomycin may lower your body's resistance, and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your household should not take oral polio vaccine since there is a chance they could pass the polio virus on to you. Also, avoid persons who have taken oral polio vaccine within the last several months. Do not get close to them, and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.
Dactinomycin can temporarily lower the number of white blood cells in your blood increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
Check with your doctor right away if you have diarrhea, nausea or vomiting, or sores or white patches on your lips, mouth, or throat while receiving this medicine.
If dactinomycin accidentally seeps out of the vein into which it is injected, it may severely damage some tissues and cause scarring. Tell your doctor right away if you notice redness, pain, or swelling at the injection site.
Make sure any doctor or dentist who treats you knows that you are using this medicine. This medicine may affect the results of certain medical tests.
