Avodart is a prescription medication containing dutasteride 0.5mg. It works by reducing levels of dihydrotestosterone (DHT), a hormone involved in both prostate enlargement and male pattern hair loss (androgenetic alopecia).
Although originally licensed in the UK for the treatment of benign prostatic hyperplasia (BPH), dutasteride may also be prescribed off-label for men experiencing progressive hair thinning, following assessment by a qualified prescriber.
