Why do we take dutasteride every single day when its half-life is 3-5 weeks? Finasteride/Dutasteride 4/24/2026
Dutasteride is often taken daily despite its long half-life because consistent dosing maintains optimal serum levels for effective DHT suppression. Some users report success with less frequent dosing, such as three times a week, but effectiveness can vary based on individual response and professional advice.

A dutasteride simulator predicts that daily 0.5 mg dosing results in higher DHT suppression compared to less frequent dosing. Twice-weekly dutasteride may be as effective as finasteride 5 mg, providing a balance between efficacy and ease of use.
community Since Dutasteride is dose dependent, is there any real difference in taking 0.5mg daily vs every other day?
Taking dutasteride daily at higher doses results in more effective DHT suppression compared to every other day dosing, due to its dose-dependent nature and long half-life. Even at lower doses, dutasteride is more effective than finasteride for hair loss.
community Why don't people start with low-dose of dutasteride?
The conversation discusses the use of dutasteride and finasteride for hair loss, with a focus on starting with low doses of dutasteride to match the DHT suppression of finasteride. It highlights the longer half-life and potential side effects of dutasteride, as well as the preference for finasteride due to its availability and research backing.
community Why is everyone not directly advised Dutasteride?
Dutasteride is less commonly prescribed for hair loss because it is not FDA-approved for this purpose, unlike finasteride, which is more accessible and preferred due to fewer side effects. Dutasteride may be more effective in reducing DHT but has a longer half-life and potentially more significant side effects.
