Propecia (finasteride) is a medicine often prescribed for men going bald, especially when the baldness occurs in the vertex and the anterior mid-scalp area. It works by preventing the conversion of male hormone testosterone into dihydrotestosterone - a hormone thought to be responsible for hair loss. This medicine should never be taken by pregnant or breastfeeding women or those that may potentially become pregnant while taking this drug. This drug can be absorbed through the skin and affect the health of an unborn baby. If a woman touched a crushed tablet of Propecia, the area affected should be washed with some soapy water and a doctor should be contacted. Report any of the following conditions to your healthcare provider before you start your treatment to make sure taking Propecia is going to be efficient for you: bladder muscle disorder, liver disease, stricture of your urethra, prostate cancer, or abnormal liver enzyme function. Tell your health care provider about any other health concerns you have that may interfere with the success of your treatment. Taking Propecia is associated with certain mild side effects, although in the absolute majority of all cases these side effects will go away on their own and there will be no need for you to do anything about them. Here are most often reported side effects of Propecia that are considered to be mild: pain in the testicles, abnormal ejaculation, impotence or decrease sex drive, dizziness, runny nose, skin rash, headache, weakness, and tenderness in your breasts. Since some of these side effects may persist (impotence), you can talk to your health care provider about the possibility of taking some anti-impotence medicine. Since Propecia causes very few drug interactions and can be combined with most anti-impotence meds, this does not appear to big a big problem. You may not see the first results too soon - up to 4 months can be required to notice some hair growth, although in most cases men using this medication notice some progress earlier. To maintain the results achieved you will have to take Propecia all the time. Make sure you tell your health care provider about any medications or supplements you are using at the moment, just to make sure they are not going to cause you any side effects that you may attribute to taking Propecia. Once you stop the treatment due to whatever reason - you are likely to lose all the progress achieved within the next 12 months. Therefore, before starting to take Propecia you need to make sure you are ready to take it for a long time regularly. Meanwhile, taking Propecia regularly is very important. Regular intervals between the doses will help your body respond to the treatment better. If you have trouble remembering about when you need to take a dose - it's important to come up with some way you could memorize it, as otherwise you may not benefit from your treatment as much. Never give your dose of Propecia to any other people to whom it was not prescribed.
