Finasteride: Uses, Side Effects, and FAQs

Finasteride is an FDA-approved oral treatment for male pattern baldness (androgenetic alopecia).
It works by lowering DHT levels in the scalp—a hormone linked to hair thinning and follicle shrinkage.
Finasteride is commonly used by adult men experiencing gradual hair loss, especially at the crown and hairline.
This guide explains how Finasteride works, how to take it properly, possible side effects, and who it's for.
How Finasteride Works
Finasteride lowers the level of DHT (dihydrotestosterone), a hormone that causes hair follicles to shrink and eventually stop growing hair. It works by blocking an enzyme in the body that turns testosterone into DHT.
With less DHT in your scalp, hair follicles stay healthier for longer—helping slow down hair loss and support regrowth, especially at the crown and mid-scalp.[1]
How to take Finasteride
Finasteride is taken orally once a day. It's important to take it consistently to maintain results.
Standard instructions:
- Take one 1 mg tablet per day.
- You can take it with or without food.
- Try to take it at the same time each day.
- Do not take more than one tablet in 24 hours.
If you miss a dose:
- Take it as soon as you remember.
- If it's almost time for your next dose, skip the missed one.
- Do not double up — taking more won't speed up results and may increase side effects.
Who Can Take Finasteride
Finasteride is intended for adult men aged 18 and above experiencing male pattern hair loss.
It is not recommended for:
- Women, especially those who are or may become pregnant.
- Children and adolescents under 18 years old.
- Men with a known allergy or hypersensitivity to Finasteride.
- Individuals with a history of certain prostate conditions (consultation required).
As with any medication, consult a healthcare provider before starting Finasteride, especially if you have underlying medical conditions or are taking other medications.
Side Effects of Finasteride
Finasteride is generally well tolerated, but some users may experience side effects.
Common side effects include:
- Decreased libido, difficulty achieving or maintaining an erection, and difficulty ejaculating.
- Breast tenderness or slight enlargement.
- Mood changes such as anxiety, irritability, or low mood (less common).
Most side effects are mild and may improve with continued use or after stopping treatment.[2]
If any symptoms persist or worsen, consult a healthcare provider.
Medicines You Should Not Use with Finasteride
Finasteride doesn't have any well-known or major drug interactions.
Still, it's important to tell your doctor about all other medications or supplements you're taking before starting treatment.
Avoid using it alongside other hormonal or prostate-related treatments unless specifically recommended by a healthcare professional.
