Are designed specifically to treat male pattern hair loss (androgenetic alopecia) in men. Their effectiveness in bitemporal recession has not been proven, and they are not intended for use in women. These tablets can be taken with or without food. The suggested dosage is one 1 mg tablet daily. Generally, it takes at least three months of consistent use to see results, and ongoing use is necessary to maintain benefits. Periodic re-evaluation is advised. If treatment is discontinued, any positive effects will likely reverse within a year.

6. Dizziness: Lightheadedness or dizziness may occur, especially when standing up from a sitting or lying position.

WARNINGS
1. Women's Exposure - Male Fetus Risk
Finasteride tablets are not for women. Pregnant or potentially pregnant women should avoid handling crushed or broken tablets due to the risk of absorption and potential harm to a male fetus. The tablets are coated to prevent contact with the active ingredient during normal handling.
2. PSA Effects
In clinical studies with men aged 18 to 41, finasteride tablets reduced serum PSA levels. In older men with BPH, PSA levels decreased by about 50%. Finasteride may also lower PSA levels in prostate cancer patients. Consider these findings when interpreting PSA results for men on finasteride. Non-compliance may affect test results.
3. High-Grade Prostate Cancer Risk with 5-Reductase Inhibitors
Men aged 55+ in the 7-year PCPT with normal digital rectal exams and baseline PSA ≤3 ng/mL had an increased risk of high-grade prostate cancer when taking finasteride 5 mg/day. Similar results were found with dutasteride. The impact of 5α-reductase inhibitors on prostate volume or study-related factors is unclear.
4. Pediatric Patients
Finasteride tablets are not for use in pediatric patients.
