1. What is Antiprost and what is it used for

Antiprost belongs to a group of medicines called 5α-reductase inhibitors. These medicines reduce the size of the prostate gland in men.
Antiprost is used to treat and control benign prostatic hyperplasia (BPH). It reduces the size of the enlarged prostate gland, improves urine flow, and relieves symptoms associated with BPH. It also reduces the risk of acute urinary retention and the need for surgical treatment.

2. Important information before taking Antiprost

When not to take Antiprost:

  • in women (see also “Pregnancy and breastfeeding”)
  • in children.
