Finpecia

Finpecia is a prescription medication containing the active ingredient finasteride, specifically formulated to treat male pattern hair loss (androgenetic alopecia). It works by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), the hormone primarily responsible for follicular miniaturization and hair loss in genetically predisposed individuals. Clinical studies demonstrate its efficacy in slowing hair loss progression and promoting regrowth in the vertex and anterior mid-scalp areas. As a 5α-reductase inhibitor, it represents a cornerstone of evidence-based medical management for this condition.

Common use

Finpecia is indicated for the management of male pattern hair loss in men aged 18 years and older. It is specifically approved for use in androgenetic alopecia, characterized by progressive hair thinning in a distinctive pattern involving the vertex and anterior mid-scalp regions. Treatment is most effective when initiated early in the hair loss process, as it primarily works to prevent further loss rather than reverse complete baldness. Patients typically notice initial effects on hair shedding within 3-6 months, with visible improvements in hair density becoming apparent after 6-12 months of continuous therapy.

Dosage and direction

The recommended dosage is one 1mg tablet taken orally once daily, with or without food. Administration should occur at approximately the same time each day to maintain consistent serum drug levels. Tablets should be swallowed whole with a full glass of water; they should not be crushed or chewed. Treatment continuation is necessary to sustain benefits, as discontinuation will lead to reversal of effects within 12 months. Dosage adjustment is not typically required for elderly patients or those with renal impairment, though hepatic impairment may warrant careful monitoring.

Precautions

Patients should undergo appropriate evaluation to confirm diagnosis of androgenetic alopecia before initiation. Regular monitoring of prostate-specific antigen (PSA) levels may be indicated, as finasteride reduces serum PSA concentrations by approximately 50%. Women who are or may become pregnant must not handle crushed or broken tablets due to risk of absorption through skin and potential teratogenic effects. Patients should be advised that initial increased hair shedding may occur during the first few months of treatment before therapeutic benefits manifest. Periodic assessment of treatment response and tolerance is recommended.

Contraindications

Finpecia is contraindicated in women who are pregnant or may become pregnant due to risk of abnormalities in male fetal genital development. It is also contraindicated in pediatric patients and individuals with known hypersensitivity to finasteride or any component of the formulation. Patients with existing severe hepatic impairment should use with extreme caution. The medication is not indicated for use in women with androgenetic alopecia or hirsutism.

Possible side effects

The majority of adverse effects are mild and transient. Most commonly reported include decreased libido (1.8%), erectile dysfunction (1.3%), and ejaculation disorders (1.2%). These sexual side effects typically resolve with continued treatment or upon discontinuation. Less frequently reported effects include breast tenderness and enlargement, hypersensitivity reactions including lip swelling and skin rash, and testicular pain. Post-marketing reports have described persistent sexual dysfunction continuing after discontinuation, though causal relationship remains uncertain. Laboratory abnormalities may include decreased semen volume and concentration.

Drug interaction

No clinically significant drug interactions have been identified with finasteride 1mg. However, theoretical interactions may occur with other 5α-reductase inhibitors. Concurrent use with saw palmetto or other herbal supplements with anti-androgenic properties may potentiate effects. Although not specifically studied, interactions with medications metabolized by CYP3A4 enzyme system are not anticipated due to finasteride’s limited effect on cytochrome P450-linked drug metabolizing enzymes.

Missed dose

If a dose is missed, it should be taken as soon as remembered unless it is nearly time for the next scheduled dose. In that case, the missed dose should be skipped and the regular dosing schedule resumed. Patients should not take a double dose to make up for a missed one. Consistency in daily administration is important for optimal therapeutic effect, but occasional missed doses are unlikely to significantly impact overall efficacy.

Overdose

No specific symptoms of overdose have been reported. Single doses up to 400mg and multiple doses up to 80mg daily for three months have been administered without significant adverse effects. In case of suspected overdose, symptomatic and supportive treatment should be initiated. As finasteride is highly protein-bound, dialysis is unlikely to be beneficial. Medical attention should be sought if large quantities are ingested, particularly by women of childbearing potential.

Storage

Store at room temperature (15-30°C) in a dry place protected from light and moisture. Keep in the original container with the lid tightly closed. Do not transfer tablets to other containers. Keep out of reach of children and pets, particularly women who are or may become pregnant. Do not use after the expiration date printed on the packaging. Proper disposal of unused medication is recommended to prevent accidental exposure.

Disclaimer

This information is provided for educational purposes only and does not constitute medical advice. Finpecia is a prescription medication that should be used only under the supervision of a qualified healthcare professional. Individual results may vary, and not all patients will experience the same degree of benefit. Patients should discuss potential risks and benefits with their physician before initiating treatment. Proper diagnosis and monitoring are essential for safe and effective use.

Reviews

Clinical trials involving over 1800 men demonstrated that 48% of finasteride-treated patients showed increased hair growth at 24 months compared to 7% with placebo. Patient-reported outcomes indicate high satisfaction with maintenance of existing hair, though regrowth results vary individually. Long-term studies up to 5 years confirm sustained efficacy with continuous use. Real-world evidence supports the clinical trial findings, with most patients reporting stabilization of hair loss and many experiencing measurable improvements in hair count and coverage.
