Propecia is a medication used to treat male pattern baldness and an enlarged prostate. It works by blocking the conversion of testosterone to dihydrotestosterone, which is a hormone responsible for the development of male sex characteristics and the growth of prostate tissue. The recommended dosage for Propecia is one 1mg tablet taken once daily. The medication should be taken orally with water and can be taken with or without food. It's important to note that Propecia has a limited distribution in the body and it only works on the scalp, so taking more than one tablet per day will not increase its effectiveness. It is also important to note that Propecia should only be used by men, as it can cause virilization effects such as hirsutism, acne, and deepening of the voice in women. Women who are pregnant or may become pregnant should avoid contact with men who are taking Propecia. If you have any questions about the proper dosage of Propecia, please consult your doctor or pharmacist. They can help you determine the best course of treatment for your individual needs. Remember that selfmedication can be dangerous and it is important to follow the instructions of a healthcare professional.
