Dutasteride works by blocking the enzyme 5‑alpha reductase, which normally converts testosterone into dihydrotestosterone (DHT), a hormone that enlarges the prostate gland and also causes hair loss. This suppression of the enzyme shrinks enlarged prostates, improves urinary flow, and slows male‑pattern baldness progression.

Pregnancy

Dutasteride is used for urinary problems in men only, and the evidence of its use in pregnancy shows birth genital defects in male children.  So, always consult a doctor before using it.

Breastfeeding

Dutasteride is used in men only, and evidence suggests its use during breastfeeding may harm babies. So always consult a doctor before use.

Kidney and Liver Problems

Dutasteride is not advised for patients with liver or kidney damage because it may cause toxicity.  So, consult your doctor immediately if any problems occur.

Avoid the use of alcohol and alcohol-containing drinks, as it raises your risk of low blood pressure from dutasteride.  So, always consult and explain your situation to the doctor before prescribing.

Avoid taking dutasteride with the following medicines, as it may increase or decrease the desired effect, or in worse cases, it could be fatal:
