Propecia, containing 5mg of finasteride, is a prescription medication used to treat male pattern baldness (androgenetic alopecia). It works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT). High DHT levels are a major contributor to hair loss. This reduction in DHT can lead to hair regrowth and slowed hair loss in many men. However, results vary significantly, and consistent use is critical for maintaining any benefits.
Dosage and Administration
The standard dosage is one 5mg tablet daily. Take it at the same time each day for best results. Do not crush, chew, or break the tablets. Always follow your doctor’s instructions precisely. While the 5mg dose is usually prescribed for hair loss, your doctor might adjust it depending on your individual needs and response to treatment. Remember, this medication is intended for long-term use. Discontinuing treatment may lead to hair loss resuming.
Potential Side Effects
Common side effects include decreased libido, erectile dysfunction, and ejaculation problems. These are usually mild and temporary, but if they persist or worsen, contact your doctor immediately. More serious, though rare, side effects include breast tenderness or enlargement. Inform your doctor about any medical conditions, particularly liver problems, before starting treatment. Women who are or may become pregnant should avoid handling crushed or broken tablets.
Important Considerations
Finasteride is not a cure for baldness. It slows hair loss and may stimulate regrowth in some men, but it won’t reverse all hair loss. Results are gradual and can take several months to become noticeable. Regular blood tests might be needed to monitor liver function. Discuss your expectations and any concerns with your doctor before beginning treatment. They can help you determine if Propecia is the right choice for you.
