Männlicher Haarausfall 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.

Before taking finasteride

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:

  • Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.

  • Wenn Sie andere Medikamente einnehmen. Dazu gehören auch Medikamente, die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

How to take finasteride

  • 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.

Das Beste aus Ihrer Behandlung herausholen

  • 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.

Can finasteride cause problems?

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.

Finasteride side-effects (these affect fewer than 1 in 10 men)

Was kann ich tun, wenn ich das erlebe?

Reduced desire to have sex, inability to get an erection, breast tenderness, depressed mood, allergic-type reactions

Wenn eines dieser Probleme auftritt, sprechen Sie mit Ihrem Arzt

Wichtig: if you develop any pain or lumps in your breast area, or any discharge from your nipples, you should tell your doctor. This is because there have been a few rare reports of breast cancer in men taking 5-alpha reductase inhibitors like finasteride and dutasteride.

Wichtig: there have been reports of depression in men taking finasteride, and in rare cases, thoughts of self-harming. Patient alert cards are now included with your medicine alerting you to this fact. You should share this information with your family or friends so that they can be alert for any changes in your mood. If you develop any signs of depression whilst being treated with finasteride, or you have any concerns about your mood, make an appointment to see your doctor.

If you are taking finasteride for prostate problems, you should continue to take your medication until you have spoken with your doctor and agreed a plan.

If you are taking finasteride (Propecia) for male pattern baldness, you should stop taking this medication and make an appointment to see your doctor.

In addition, taking finasteride has caused problems with sexual function in some men, including loss of libido and problems maintaining an erection. This has sometimes continued after stopping treatment. Speak with your doctor if you are concerned about this.

Wenn Sie andere Symptome bemerken, die Ihrer Meinung nach auf die Tabletten zurückzuführen sein könnten, sprechen Sie mit Ihrem Arzt oder Apotheker für weitere Ratschläge.

Häufig gestellte Fragen

Why is finasteride not available on the NHS for male pattern baldness?

Finasteride is a prescription-only medicine but it is not funded by the NHS for treating male pattern baldness. This means patients need to pay the full cost of the tablets when they get their supply.

What is dihydrotestosterone and how does it relate to hair loss?

Dihydrotestosterone is a hormone that hair follicles become sensitive to as balding develops. This sensitivity causes the hair follicles to shrink, leading to thinner hair that is shed more quickly. Finasteride works by blocking the conversion of testosterone into dihydrotestosterone.

When should I tell my doctor that I am taking finasteride?

You should inform your doctor or any medical professional about your finasteride use if you are having an operation or any medical treatment. It's particularly important to mention if you need a blood test for prostate cancer, as finasteride can interfere with the results of this test.

What should I do if I experience changes in mood or signs of depression while taking finasteride?

There have been reports of depression, and in rare cases, thoughts of self-harming, in men taking finasteride. Your medicine comes with a patient alert card about this. You should share this information with family or friends so they can help monitor your mood. If you notice any signs of depression or have concerns about your mood, stop taking the medication and schedule an appointment to see your doctor.

Are there any specific situations where women should avoid handling finasteride tablets?

Yes, women who are pregnant should not handle finasteride tablets because the medicine may cause harm to an unborn baby.
