There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.This medication is used to slow down the growth of unwanted hair on the face and under the chin in women. It should not be used for hair on other parts of the body. It blocks a certain natural substance (an enzyme) that is needed for hair growth in the skin. This effect slows hair growth and may also make the hair finer and lighter. It does not remove hair or cause the hair to fall out.
This drug is not for use in children younger than 12 years.
