Overview
Finasteride is a synthetic drug used to inhibit a specific enzyme in the body.
Finasteride is a synthetic pharmaceutical that selectively inhibits the enzyme 5-alpha reductase, which plays a role in hormone metabolism. In Canada, it is available under brand names such as Proscar® and Propecia®. These brands differ mainly in dosage strength and indications. Proscar® typically comes as a 5 mg tablet, while Propecia® is available as a 1 mg tablet. Both contain the same active ingredient, finasteride.

How Finasteride Works
Finasteride blocks 5-alpha reductase to reduce certain hormone conversion.
Finasteride works by blocking the 5-alpha reductase enzyme, which normally converts testosterone into dihydrotestosterone (DHT), a hormone in the body. By reducing DHT levels, finasteride affects biological processes that depend on this hormone. This action is reversible and dose-dependent.
Dosage Instructions of Finasteride
Available in tablet form with different strengths in Canada.
In Canada, finasteride is available orally as film-coated tablets. The common strengths include 1 mg and 5 mg tablets, corresponding to different treatment purposes. Tablets are usually round and scored for easy splitting.
Follow doctor’s guidance; take tablets orally with or without food.
Dosage varies by product and individual needs. It is important to take finasteride exactly as prescribed by a healthcare professional. Tablets may be taken with or without food, usually once daily. Do not alter dosage or discontinue without medical advice.
Storage Instructions
Store at room temperature away from moisture and light. Keep finasteride tablets in their original container tightly closed. Store at temperatures between 15°C and 30°C (59°F and 86°F). Protect from moisture, heat, and direct sunlight to maintain medication effectiveness.
Side Effects of Finasteride
May cause mild to serious reactions; consult a doctor if concerned.
Common side effects reported include mild gastrointestinal discomfort, dizziness, or headache. Some users may experience sexual side effects such as decreased libido or erectile difficulties. Serious adverse effects are rare but require immediate medical attention. Always report any unusual symptoms to a healthcare provider.
Important Safety Information About Finasteride
Health Canada advises careful use; discuss risks with your doctor.
Health Canada warnings emphasize that finasteride is not suitable for everyone. Pregnant women should avoid handling crushed or broken tablets due to potential absorption risks. Inform your doctor about any existing medical conditions or medications before starting finasteride.
Drug Interactions
Avoid certain medications and supplements; consult your pharmacist.
Finasteride may interact with other drugs metabolized by the liver or affecting hormone levels. Inform your healthcare provider about all medications and supplements you are taking to avoid interactions. Avoid self-medicating or combining with other hormone-affecting agents without medical advice.
