Product information

How Does Propecia Work?

Propecia is a hair loss treatment containing the active ingredient finasteride. This substance counters the over-sensitivity to a hormone called dihydrotestosterone or DHT, which is found near the scalp and leads to pattern baldness. By blocking the enzyme that processes testosterone and turns is into DHT an increase of testosterone is achieved, which encourages hair growth on the scalp. Further body hair is not affected by the use of propecia tablets.

How do I take finasteride tablets?

Propecia tablets should be taken with a full glass of water, with or without food. The standard dose of one tablet a day should not be exceeded. If you forget to take a tablet skip the dose and take the medication again as usual on the next day. Please consult a doctor immediately if you exceeded the prescribed dose by accident.

How effective does the treatment work?

Finasteride, the active substance in propecia, needs about 3-12 months in order to work fully effective and aid hair growth or stop hair loss. As hair growth is a long-term process visible changes will only occur slowly. However, the treatment usually works within half a year in most cases. The treatment only prevents hair loss and aids hair growth as long as you take the tablets.

Once you stop taking them you will lose the regrown hair within 6-12 months. The medication works best if you take the finasteride tablets on a daily basis.

How to use Propecia?

Take as prescribed and consult the leaflet provided for more information.
