Frequently Asked Questions
Can I take Finasteride every other day?
Not recommended. Clinical trials show 1mg daily provides optimal DHT suppression (68% reduction vs. 50% with alternate-day dosing).
Should I take Finasteride morning or night?
Either is fine. Choose a consistent time that fits your routine. Night dosing may help if you experience fatigue.
What if I swallow Finasteride without water?
Generally safe, but water helps prevent esophageal irritation. Seek medical advice if tablet feels stuck.
Can I cut Finasteride 5mg tablets into quarters?
No. 5mg tablets aren't scored for accurate division. Use prescribed 1mg tablets for hair loss.
How soon after food can I take Finasteride?
Immediately. Food doesn't affect absorption. Take with meals if you experience stomach upset.
