International Nonproprietary Name
The active ingredient known as Finasteride serves as the cornerstone of medications related to hair loss treatment. This drug has gained notable recognition under the brand name Propecia, primarily available in a dosage of 1 mg in film-coated tablet form. Additionally, a dosage of 5 mg is marketed as Proscar, intended for benign prostatic hyperplasia (BPH).
ATC Code and Drug Classification
Finasteride falls under the ATC code D11AX10, categorizing it within dermatological treatments and other dermatological preparations. This classification highlights its primary application for treating androgenetic alopecia, also known as male pattern hair loss.
Available Forms and Dosages
The medication is available in the following forms:
| Form | Dosage |
|---|---|
| Tablet | 1 mg (Propecia, for androgenetic alopecia) |
| Tablet | 5 mg (Proscar, for benign prostatic hyperplasia) |
Manufacturers and Suppliers
The primary manufacturer of Finasteride is Merck & Co., recognized as the original developer of the drug. Alongside the branded versions, several generics are produced by various regional manufacturers, ensuring availability across different markets.
Registration Status
In Canada, the United States, and several other jurisdictions, Finasteride is classified strictly as a prescription medication, highlighting its regulated status as Rx only. There is no over-the-counter (OTC) version available, which underscores the importance of professional guidance when using this treatment.
Understanding the Pharmacology of Finasteride
Finasteride functions by inhibiting the enzyme 5-alpha-reductase. This enzyme is responsible for converting testosterone into dihydrotestosterone (DHT), a hormone that contributes to hair loss in men with androgenetic alopecia. By blocking this enzyme, Finasteride lowers DHT levels, helping to halt hair loss and may even promote regrowth.
Onset, Metabolism, and Elimination
When taken, the onset of action typically occurs within a few weeks, although visible changes in hair growth can take up to six months or longer. Finasteride is primarily metabolized in the liver, with a half-life of around five to six hours. This means it remains in the body long enough to be effective while being eliminated efficiently.
Potential Drug Interactions
While generally well-tolerated, it's essential to be aware of interactions with other medications, certain foods, and alcohol that may affect Finasteride's efficacy or safety. Always inform healthcare providers about all medications being taken to avoid adverse effects and to ensure safe usage.
Approved and Off-label Indications
Finasteride has received FDA and EMA approval specifically for treating androgenetic alopecia, primarily in men. While it is predominantly used for this purpose, there may also be off-label uses particularly in dermatological settings that practitioners may consider based on individual patient needs.
Considerations for Special Populations
This medication is not indicated for use in children or women, particularly those who are pregnant or may become pregnant, due to significant risks. Older adults may also require careful monitoring to ensure the safe administration of the drug, although specific adjustments for this group have not been widely established.
Dosage Guidelines and Administration
The recommended dosage for Finasteride in treating androgenetic alopecia is 1 mg taken orally once a day. For benign prostatic hyperplasia, the dosage is 5 mg daily. It is crucial to adhere to prescribed dosages to maximize benefits and minimize risks.
Adjustments for Special Conditions
Adjustments may be needed based on various health conditions. For individuals with liver impairments, caution is advised. For dosing in the elderly, while no explicit adjustments are recommended, monitoring efficacy is essential.
Duration of Treatment
Patients should expect to wait at least three months to see any initial benefits. The maximum advantages typically manifest at six to twelve months. Effective storage conditions include keeping the tablets at room temperature, away from moisture and light, to maintain their efficacy.
Missing Doses and Overdose Management
If a dose is missed, it should be taken as soon as remembered, unless it’s close to the time for the next dose. Overdoses are rare, as studies show even high doses do not usually cause serious adverse effects.
Safety & Warnings
Understanding safety warnings for Propecia is vital for anyone considering this medication. It’s important to recognize both absolute and relative contraindications. Absolute contraindications include:
- Hypersensitivity to finasteride or any component of the tablet.
- Pregnancy or the possibility of becoming pregnant, as it poses significant risks to male fetal genitalia.
Relative contraindications, such as liver dysfunction, require careful consideration due to the drug's hepatic metabolism.
Common side effects might include decreased libido, erectile dysfunction, and ejaculation issues. Affected individuals might also experience rare but serious problems like breast tenderness and even breast cancer. It’s crucial for healthcare providers to monitor any adverse reactions, especially in vulnerable groups like pregnant women.
No black box warnings exist for Propecia, but potential risks related to depression and prostate cancer should be discussed with healthcare professionals. Monitoring and open communication with doctors can enhance treatment efficacy while reducing risks.
Patient Experience
User reviews across platforms like Drugs.com, Reddit, and WebMD suggest mixed experiences with Propecia's effectiveness. While many users report hair regrowth and satisfaction, others voice concerns about side effects affecting their quality of life.
Online forums often buzz with personal anecdotes, showing users sharing their journeys. One common thread is the discussion around side effects such as libido reduction, which has led some to discontinue treatment despite positive hair growth results.
Overall, adherence levels vary. Some users express satisfaction with their outcomes, while others feel that the side effects outweigh the benefits. Engaging in conversation within support groups can provide further insights and help patients feel less alone in their experience.
Alternatives & Comparison
For those contemplating alternatives to Propecia, options like Dutasteride and Minoxidil are prevalent in Canada. Dutasteride is known for being a more potent inhibitor of both Type I and Type II 5-alpha-reductase, while Minoxidil acts as a topical vasodilator.

The average price for Propecia can range from 60 to 90 CAD for a month’s supply, depending on the pharmacy and any ongoing discounts. Packaging typically includes a course of 30 film-coated tablets at 1 mg strength.
Demand patterns show that the market for Propecia remains stable, with fluctuations observed during seasonal trends related to hair loss awareness. Continuity of care is essential, as patients often require long-term therapy to maintain results.
Research & Trends
The landscape surrounding Propecia, or finasteride, is continually evolving. Recent studies from 2022 to 2025 have delved into the medication's efficacy and safety. Notably, a meta-analysis published in late 2023 has confirmed that Propecia offers substantial hair regrowth benefits in a significant percentage of men suffering from androgenetic alopecia. Clinical trials indicate that the drug's effects peak between six to twelve months of treatment, urging patients to maintain consistency for optimal results.
In addition to its traditional usage, researchers are exploring potential experimental applications. Investigations into finasteride's effects on conditions like hirsutism and certain types of acne are in preliminary phases, showing promise but still requiring more substantial clinical validation before any formal approval.
On the generics front, the market is robust. With Propecia's patent expiration in many regions, generic finasteride has become widely available, making treatment more affordable. Studies on long-term effects of finasteride, particularly among users opting for generics, are ongoing. Advantages in affordability without significant variances in efficacy lead many to consider generics an excellent alternative.
Guidelines for Proper Use
For maximizing benefits from Propecia, knowing how to take it correctly is crucial. This medication should ideally be consumed at the same time each day, with or without food for convenience.
A few things to keep in mind include:
- Avoid taking it at random times; stick to a routine.
- Stay hydrated, but no need to overthink water intake.
Certain interactions can impact its effectiveness. It’s best to avoid consuming alcohol in excess, as it could exacerbate side effects like dizziness or fatigue. Also, be cautious of herbal supplements containing DHT blockers, which may interfere with finasteride’s action.
Storing Propecia properly ensures its longevity and effectiveness. Keep it at room temperature, secure from humidity and light. Tablets should remain in their original blister packaging until ready to use, as this protects them from degradation.
Common mistakes with adherence include forgetting doses or abruptly stopping the use. It's essential to consult the product leaflet and engage with a healthcare provider before making any changes to your regimen. Regular follow-ups will help maintain the desired outcomes and manage side effects effectively.
