How does Propecia work?
Propecia lowers the levels of Dihydrotestosterone (DHT) in the scalp causing the hair follicles to shrink and eventually stop functioning.
This process helps to reverse the balding process, leading to an increased hair growth and prevention of further hair loss.
DHT shrinks hair follicles
DHT may contribute to the shortening of the growth phase of hair follicles, causing them to shrink until there are fewer visible hairs left on the scalp.
PROPECIA blocks the formation of DHT
PROPECIA inhibits the development of male pattern hair loss.
How to take Propecia
Always take Propecia exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
- The usual dose is one tablet each day.
- Take this medicine by mouth.
- Propecia will not work faster or better if you take it more than once a day.
If you take too many tablets by mistake, contact your doctor immediately.
If you forget to take a tablet, skip the missed dose. Take the next one as usual. Do not take a double dose to make up for a forgotten dose.

How long do I have to take Propecia for?
Continuous treatment is required for sustained results although Propecia will start working straight away.
You could see results in as little as three months.
If you stop taking the medicine, the hair loss process will begin again. Any results achieved will begin to reverse by six months and be gradually lost by nine to 12 months, if you stop taking the medicine.
Possible Side Effects
Like all medicines, Propecia can cause side effects, although not everybody gets them. The following side effects may happen with this medicine:
If you have an allergic reaction, stop taking it and see your doctor straight away.
The signs may include:
- Skin rashes, itching, or lumps under your skin (hives)
- Swelling of lips, face, tongue or throat
- difficulty swallowing
- breathing difficulties.
Other side effects may include:
- you may be unable to have an erection (impotence)
- you may have less desire to have sex
- you may have problems with ejaculation, for example a decrease in the amount of semen released during sex. This decrease in the amount of semen does not appear to affect normal sexual function.
These side effects above may disappear after a while if you continue taking Propecia. If these symptoms persist, they usually resolve after stopping Propecia.
Other side effects reported in men are:
- breast swelling or tenderness
- palpitations (feeling your heartbeat)
- Changes in the way your liver is working, which can be shown by a blood test
- pain in the testicles
- persistent difficulty having an erection after discontinuation of treatment
- infertility has been reported in men who took finasteride for long time and had other risk factors that may affect fertility. Normalisation or improvement of seminal quality has been reported after discontinuation of finasteride. Long-term clinical studies about the effects of finasteride on fertility in men have not been conducted.
You should promptly report to your doctor any changes in your breast tissue such as lumps, pain, enlargement or nipple discharge as these may be signs of a serious condition, such as breast cancer. If any of these side effects gets serious, or if you notice any side effects not listed on the patient information leaflet please tell your doctor or pharmacist. It will help if you make a note of what happened, when it started and how long it lasted.
