Finasteride

Finasteride 1 mg is a prescription medication used to treat male pattern hair loss (androgenetic alopecia) in men. It belongs to a class of medicines called 5α-reductase inhibitors, which affect hormones involved in hair loss. It is not approved for use in women or children, and its effectiveness has not been established for certain patterns like a receding hairline at the temples. Use is typically part of a longer-term treatment plan, as benefits depend on continued daily use.

• Prescription oral treatment for male pattern hair loss
• Works on hormonal pathways linked to hair loss
• Men only; not indicated for women or pediatric use
• Not established for bitemporal (temple) hair loss
• Requires ongoing use to maintain results

Finasteride 1 mg is taken as an oral tablet once daily, with or without food. It is designed for consistent, long-term use rather than occasional or as-needed use. The prescribing information indicates that it may take at least 3 months or more of daily use before any benefit is observed, and continued use is recommended to maintain results over time. Your provider will determine if this treatment is appropriate and may periodically reassess your progress.

• Take 1 tablet daily
• Can be taken with or without food
• Use on a consistent daily schedule
• Do not adjust your dose without medical guidance
• Continued use helps maintain results

Finasteride can cause side effects, although not everyone will experience them. The most commonly reported effects involve sexual function, including decreased libido, erectile dysfunction, and changes in ejaculation. Some effects may continue after stopping the medication, based on postmarketing reports. There are also important safety considerations that should be taken seriously and discussed with your provider if they occur.

• Possible decreased sex drive
• Possible difficulty achieving or maintaining erections
• Possible changes in ejaculation
• Contact your provider if you notice breast changes, such as lumps or discharge
• Seek medical advice if you experience persistent or concerning symptoms

Finasteride is not a quick-fix treatment. According to the prescribing information, it may take 3 months or more of daily use before any benefit is noticed. Some people may need longer, and results can vary depending on the individual and their hair loss pattern.

• Use it daily and consistently
• Results may take several months
• Not everyone responds the same way
• Continued use helps maintain results

If you don’t notice changes after a few months, your provider may reassess whether it’s the right option for you.

If you stop taking finasteride, any benefit you experienced may gradually be lost. The prescribing information indicates that effects are typically reversed within 12 months after discontinuation.

• Hair may return to its previous state over time
• Effects are not permanent without continued use
• Stopping does not cause new hair loss beyond baseline
• Consistency is key for maintaining results

If you’re thinking about stopping, it may help to understand what to expect beforehand.

If you miss a dose, simply take your next dose at the usual time. There is no need to take extra medication to make up for a missed dose.

• Continue with your regular schedule
• Do not take double doses
• Try to maintain a consistent routine
• Occasional missed doses may affect consistency

If you frequently forget doses, setting reminders may help keep your treatment on track.
