Finasteride works by blocking the enzyme 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT). High DHT levels contribute to hair loss in men. By reducing DHT, finasteride helps slow or stop hair loss and may even promote regrowth in some individuals.
Common side effects, though usually mild and temporary, include decreased libido, erectile dysfunction, and ejaculation disorders. These generally resolve upon cessation of treatment. However, a small percentage of men experience persistent side effects even after stopping the medication. Inform your doctor immediately if you experience any concerning symptoms.
Less frequent side effects can include breast tenderness or enlargement (gynecomastia), depression, and allergic reactions. While rare, these potential side effects require prompt medical attention.
Before starting finasteride, discuss your medical history, including any existing conditions or medications, with your doctor. This allows for a proper risk assessment and ensures you are a suitable candidate. Regular monitoring is recommended during treatment to assess its effectiveness and identify any potential adverse reactions.
Remember, individual responses to finasteride vary. Results can take several months to become noticeable, and continued use is usually necessary to maintain gains. Consistency is key to achieving optimal results. Consult your doctor regularly to review your progress and address any concerns.
