Mendoxa / Dutasteride for hair loss
Hair · GuideDutasteride for hair loss: how it compares to finasteride
Dutasteride is a prescription medicine that lowers DHT, the hormone behind male pattern hair loss, more strongly than finasteride. In the U.S. it is FDA-approved for an enlarged prostate, so using it for hair loss is off-label. Some clinicians consider it when finasteride hasn't worked well enough. It needs a clinician's review.
What dutasteride is
Dutasteride blocks both types of the enzyme that converts testosterone to DHT. Finasteride blocks mainly one.
The U.S. approval is for benign prostatic hyperplasia. Dutasteride is not FDA-approved for hair loss in the U.S., so that use is off-label. The International Society of Hair Restoration Surgery notes that South Korea has approved it for hair loss. It is prescription-only and used by men.
Dutasteride vs finasteride
Dutasteride lowers DHT more and stays in the body much longer. That may mean more effect for some men, and side effects that take longer to fade.
In a 24-week randomized trial in men, dutasteride at the highest dose tested increased hair count more than finasteride. The trial was short, and some authors worked for the manufacturer. The label gives a half-life of weeks, not hours. Clinicians often try finasteride first; see finasteride and minoxidil.
Side effects of dutasteride
Possible side effects include lower libido, erection problems, changes in ejaculation and breast tenderness. They are uncommon but worth knowing about.
The label also reports mood changes, including depression. Report any side effect to your clinician. See the dutasteride prescribing information on DailyMed.
Who should not take dutasteride
Women who are or may become pregnant must not handle the capsules. Men taking it should not donate blood during treatment or for a period after stopping.
The brand label sets the blood donation window, and the handling warning refers to the brand capsule; your clinician and pharmacy give handling instructions for the form you are prescribed. Dutasteride lowers PSA, so tell any clinician who checks it. Mention liver conditions and your full medication list.
Dutasteride with minoxidil
Dutasteride targets DHT and minoxidil supports the growth phase. Clinicians sometimes combine them.
When prescribed, Mendoxa's dutasteride and minoxidil formula includes minoxidil as an oral dissolving tablet, with the strength chosen by the clinician. It is not FDA-approved as a finished product. Read about oral minoxidil for the details of that half.
Dutasteride online: getting it prescribed
A licensed clinician must review your health history before prescribing dutasteride. Mendoxa offers that review online in 49 states (not California).
The intake asks about your health, medications and hair loss history. Be wary of sellers with no prescription. A prescription is never automatic. LocumTele clinicians review every intake, and Rush Pharmacy fills when a prescription is issued.
Dutasteride hair dose was not in the file we opened
The Propecia label names dutasteride in a high-grade prostate-cancer warning, not as a hair recipe. This page does not fill that hole from memory.
| What we opened | What it means on this page |
|---|---|
| Finasteride, for contrast | 1 mg once daily for male pattern hair loss in men only. |
| Dutasteride sentence | A 4-year Avodart trial saw high-grade prostate cancer in 1 percent versus 0.5 percent on placebo. |
| Hair dose | Not printed. A clinician prescription is not a number this page invented. |
