What is Dutasteride?
Overview of the Treatment
Dutasteride is a dihydrotestosterone (DHT) blocker. This is the hormone that binds to hair follicles, causing them to shrink and eventually leading to hair loss. It can be helpful to treat hair loss as a result of androgenetic alopecia (pattern balding).
How it Works?
Compared to other DHT blockers like finasteride, dutasteride blocks all three types of isoenzymes responsible for DHT conversion. In comparison, finasteride only covers two. Learn more.
Who it’s For?
Dutasteride can be used off-label for the treatment of hair loss in men and women, but you should discuss with your doctor if you have issues with your liver or a family history of prostate cancer. Learn more.

Finasteride and dutasteride are both DHT blockers. The difference is that finasteride blocks types 2 and 3 of the 5-alpha reductase isoenzymes that cause testosterone to convert into DHT. Dutasteride covers all three types. It may be more effective since type 1 and type 2 of these isoenzymes are thought to be the most common causes of hair loss out of the three.
Some people end up switching from finasteride to dutasteride. Since dutasteride may have a higher chance of negative side effects, it’s recommended to try finasteride first to see if it works. Doctors typically advise trying finasteride for 6-12 months to see if it is effective. Since dutasteride covers more types of isoenzymes that convert testosterone into DHT, it may help more with your hair loss if finasteride isn’t working for you.
You can’t donate blood while taking dutasteride and for at least 6 months after you stop taking the drug. This is because the medication is carried in your blood and can cause birth defects if a pregnant woman receives blood with dutasteride in it. For this reason, dutasteride is also not recommended for pregnant women or men who are trying to have a baby.
You should take your dose of dutasteride as soon as you remember if you forget. If it’s near to your regular time of day you would usually take the medication, don’t double up on your dose. If you miss a dose every now and then, it shouldn’t have too much impact on your results, but the drug needs to be in your system consistently to see improvements in hair regrowth.
There are rare but serious side effects from dutasteride, including allergic reactions, tightness in the chest, difficulty breathing, and swelling. Less than 1% of patients saw other side effects relating to sexual function, such as decreased libido, ejaculatory issues, and impotence. If you experience any of these adverse reactions, you should contact your doctor to discuss altering your prescription.
