Finasteride for male pattern baldness

About finasteride for male pattern baldness

Male pattern baldness is the common type of hair loss that develops in many men at some stage. The condition is sometimes called androgenetic alopecia. It is caused by a combination of hereditary (genetic) and hormonal factors.

Hair is made in hair follicles. A hair normally grows from each hair follicle for about three years. It is then shed and a new hair grows from the follicle. As balding develops, affected hair follicles gradually become smaller than normal. Each new hair that grows is thinner and shed more quickly than before. This eventually leads to a much smaller hair follicle and a thin hair that does not grow out to the skin surface.

Male hormones are involved in causing these changes. Hair follicles convert testosterone (the main male hormone) into another hormone called dihydrotestosterone. Affected hair follicles become more sensitive to dihydrotestosterone and this causes the hair follicles to shrink.

For some men, this normal ageing process can be distressing, particularly if it is excessive or occurs early in life. Treatment with finasteride can help prevent further hair loss. It works by stopping the conversion of testosterone to dihydrotestosterone.

Finasteride is only available on a prescription from a doctor, but it is not available on the NHS. This means you will be asked to pay the full price of the tablets when you receive your supply.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking finasteride it is important that your doctor knows:

• אם אי פעם הייתה לך תגובה אלרגית לתרופה.

• אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about finasteride and will provide you with a full list of the side-effects which you may experience from taking it.

• Take one (1 mg) tablet each day, exactly as your doctor tells you to. Try to take your doses at the same time of day, as this will help you to remember to take finasteride regularly.

• Swallow the tablet whole (without breaking or crushing it) with a drink of water. You can take the tablet either with or without food.

• If you forget to take a dose on time, take it when you remember. If you do not remember until the following day, leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

• Each time you collect a new supply of tablets from your pharmacy, make sure they look to be the same as you have had before. This is because there is a high-dose brand of finasteride tablet available for the treatment of a different condition. If you are unsure that you have the correct tablets, ask your pharmacist to check for you.

• Your hair growth may start to improve within a few months, although it can take up to a year or so for you to notice the full benefit. You will need to continue treatment to maintain this effect, as the balding process returns when you stop.

• Finasteride may cause harm to an unborn baby. Because of this, women who are pregnant should not handle the tablets. Also, very small amounts of finasteride will be in your semen while you are taking this medicine. If you need further advice about this, speak with your pharmacist or doctor.

• If you are having an operation or any medical treatment, tell the person carrying out the treatment that you are taking finasteride. This is because finasteride can interfere with a blood test used to detect prostate cancer, so you must tell your doctor about taking finasteride if you need this test.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the ones associated with finasteride. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
