What's the Deal with 5-Alpha Reductase Inhibitors?
Published: Feb 09, 2024
5-alpha reductase inhibitors (5-ARIs) are a key treatment for BPH. Learn how they work and who benefits most.
How 5-ARIs Work
5-ARIs reduce the size of an enlarged prostate by blocking hormones that cause growth. This can improve urinary symptoms and reduce the need for surgery. Common 5-ARIs include finasteride and dutasteride.
Efficacy and Use
5-ARIs are effective in men with significantly enlarged prostates. They lower prostate volume and slow disease progression, minimizing the risk of acute urinary retention. These benefits make them crucial in long-term BPH management.
Potential Side Effects
Side effects of 5-ARIs can include sexual dysfunction and decreased libido. Some patients report persistent symptoms even after stopping the medication. It's important to discuss these potential impacts with a healthcare provider.
