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. Before you take Cosmegen Lyovac Injection
When should this medicine not be used?
You should not be given Cosmegen injection if:
• you are allergic to dactinomycin or any of the ingredients in
Cosmegen injection
• 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.
Before you take this medicine
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
Taking other medicines
Always tell your doctor or pharmacist if you are taking any other medicines,
because using some medicines together can be harmful.
• 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.
Pregnancy and breast feeding
If you are pregnant, think you might be pregnant or are planning to become
pregnant, tell your doctor immediately.
If you are breast feeding, you should not be given Cosmegen injection.
Driving and operating machines
Cosmegen can cause some people to feel less alert. Make sure you are not
affected before you drive or operate machinery.
3. How to take Cosmegen Lyovac Injection
How will your medicine be given?
You will be given your Cosmegen injection by a doctor or nurse who is
experienced in the use of cancer treatments.
The number of injections you need will depend upon your condition, your
response to the medicine, any possible side effects, and whether you are
having other treatments at the same time.
You may be given Cosmegen either as an injection (see below) or mixed with
another solution as an infusion (a ‘drip’) into your vein.
It must not be taken by mouth.
There are two ways of giving Cosmegen injection:
• into a vein
• directly into the site of the cancer.
The dosage is different for each method.
In these cases your doctor will calculate the doses required and will tell you
how long your treatment might take. Your doctor will determine the correct
dose and duration of the treatment depending on your type of cancer.
Typical doses for injection into a vein:
• Not more than 15 micrograms per kg of body weight for 5 days in adults
and children, or
• 400-600 micrograms per square metre of body surface daily, for 5 days.
Typical doses for giving Cosmegen directly into the site of the cancer:
• For the legs or pelvis, 50 micrograms per kg bodyweight.
• For the arms, 35 micrograms per kg bodyweight.
Your doctor will advise you of the method and number of injections and
courses you require.

If you miss a dose or are given too much
Your response to the medicine and your condition will be monitored by your
doctor, who will determine if changes to your treatment are needed.
If you are confused or concerned about the number of doses you have
received, or think you may have been given too much medicine, talk to your
doctor immediately.
4. Possible side effects
As with all medicines, Cosmegen may cause side effects in some patients. However,
these side effects are usually reversible once your treatment has stopped.

deteriorate rapidly and death can follow

top layer of skin to die, peel, and shed

fever, chills, aching muscles and generally feeling unwell

virus), a painful enlarged liver, fluid retention)
