Basics

Avodart®, also known by its generic name dutasteride, is a prescription medication primarily used to treat benign prostatic hyperplasia (BPH), or an enlarged prostate. It’s also sometimes prescribed off-label for androgenic alopecia, or pattern hair loss.

Avodart works by inhibiting 5-alpha reductase (5-AR), an enzyme that converts testosterone into dihydrotestosterone (DHT). DHT is a hormone sometimes responsible for prostate enlargement and hair loss in certain people. 

Side effects of Avodart are usually mild and may include decreased libido, erectile dysfunction, and breast tenderness or enlargement. Avodart may interact with other medications that affect certain liver enzymes.

Avodart is sometimes prescribed off-label to treat hair loss, but it’s important to keep in mind that the drug is not officially approved for this purpose. Anyone taking it should be monitored closely by a healthcare provider.

*Avodart Approved Uses

Avodart (dutasteride) is indicated for the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate to:

  • Improve symptoms

  • Reduce the risk of acute urinary retention

  • Reduce the risk of the need for BPH-related surgery

Avodart in combination with the alpha-adrenergic antagonist, tamsulosin, is indicated for the treatment of symptomatic BPH in men with an enlarged prostate

*Avodart Drug Category

5 alpha-reductase inhibitor

FAQs

Research has shown that both Avodart and Proscar (brand-name dutasteride and finasteride, respectively) can be effective interventions for reducing hair loss, but one study suggests dutasteride may be better at blocking dihydrotestosterone (DHT), a hormone linked to hair loss in men, and encouraging thicker hair growth. However, only finasteride is approved by the United States Food and Drug Administration (FDA) to treat hair loss, while dutasteride may be prescribed off-label at the discretion of a healthcare provider.

Avodart isn’t FDA-approved for hair loss in men because not enough research has been done to support its approval.

Yes, it can. The active ingredient in Avodart is dutasteride. Dutasteride’s side effects may include erectile dysfunction, decreased libido, and problems with ejaculation. It’s possible for these side effects to persist after you stop taking the medication.

Yes, in certain cases. Avodart is not prescribed to women who are pregnant or can become pregnant because the medication can cause birth defects. However, it may be prescribed off-label for female pattern hair loss. In one study of women with female pattern hair loss who took the generic form of the medication, dutasteride, for three years, the drug effectively increased their hair thickness and stopped further hair loss.
