1. What Cosmegen Lyovac Injection is and what it is used for
What is in your medicine and how does it work?
The name of your medicine is Cosmegen Lyovac injection and its active ingredient is dactinomycin.
Dactinomycin belongs to a group of medicines called antibiotics.
It works by preventing the reproduction of cells, especially abnormal cells which are associated with some types of cancer.
It also prevents reproduction of normal cells that multiply quickly.
Why do you need to be given this medicine?
Your doctor has prescribed Cosmegen for you because you may suffer from one of the following conditions which your doctor should have explained to you:
Wilms’ tumour (a type of kidney cancer which usually occurs in children)
Rhabdomyosarcoma (a rare cancer of the muscle)
Ewing’s sarcoma (a type of bone cancer)
cancer of the testis and uterus
melanoma (a type of skin cancer).
Cosmegen may also be used in the treatment of other cancers.
Your doctor may prescribe radiotherapy as well as Cosmegen.
2. What do you need to know before you use Cosmegen Lyovac Injection
Do not use Cosmegen Lyovac Injection
You should not be given Cosmegen injection if:
you are allergic to dactinomycin or any of the other ingredients of this medicine (listed in section 6).
you have chickenpox or shingles
you are, or think you may be, pregnant
you are planning to become pregnant
you are breast feeding.
If you think any of these apply to you, tell your doctor.
Warnings and precautions
There are other things regarding Cosmegen which you should know about. These are given below so that special care can be taken where needed.
Splashes or spills
Cosmegen is extremely harmful to soft tissue such as skin, and any leakage on to the skin will cause soft-tissue damage. Any spills or splashes of Cosmegen must be washed off immediately with lots of water or saline (salt water).
Medical attention should be sought immediately.
Radiation therapy
If you are receiving Cosmegen with radiation therapy your doctor will have to keep a close watch on you as there is an increased possibility of some other side effects.
Kidney, liver, bone marrow
Cosmegen may cause kidney, liver or bone marrow problems. This can result in a lower number of red and white blood cells and a lower number of platelets. Symptoms of lower red blood cells include tiredness, headaches, being short of breath when exercising, dizziness and looking pale. A lower number of white blood cells may make it harder for you to fight off infections. Symptoms of lower platelet counts include excessive bruising or a harder time to stop bleeding if you have a cut. Your doctor should assess these functions frequently.
Other medicines and Cosmegen Lyovac Injection
Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.
X-ray: You should tell your doctor if you received X-ray treatment at any time. There is some information that, rarely, other tumours may occur following treatment with X-rays and medicines like Cosmegen.
Antibacterial medicines: Cosmegen may alter the results of tests that are done to measure the levels of antibacterial medicines.
Fertility, pregnancy and breast feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
If you are breastfeeding, you should not be given Cosmegen injection.
It is recommended to use effective contraception during treatment with COSMEGEN, and for at least 6 months after the last dose for women, and 3 months for men. Please consult your doctor or pharmacist if you have any questions about the contraception methods to be used during this period.

3. How to use Cosmegen Lyovac Injection
How will your medicine be given?
