Propecia (finasteride) is a drug prescribed for the treatment of male pattern baldness. It works by preventing the conversion of testosterone to DHT (dihydrotestosterone). DHT is thought to be responsible for hair loss in men. The effects of Propecia will not become obvious instantly - most patients need about three months for the first results to be visible. Do not take more of this drug than recommended by your doctor to avoid an overdose. If you think you have taken too much of Propecia seek emergency medical help. Your dosage and schedule are based on the assessment of your health condition. You must not share Propecia with other people or let pregnant women handle your medicine as it can get absorbed through skin and cause birth defects.
Simultaneous use of Propecia with other drugs is not recommended. In case of taking any other drugs of supplements make sure you mention this fact when talking to your doctor. Besides taking Propecia regularly, you will have to follow some of your doctor's recommendations concerning your diet, lifestyle and the amount of exercise you get. This will help you to benefit from this drug and possibly avoid unwanted side effects.
