Silodosin — Uses, Dosage, Side Effects & Safety

Drug class: Alpha-1 adrenergic receptor antagonist (Alpha blocker)

Overview

Silodosin is a prescription medication used to treat the symptoms of benign prostatic hyperplasia (BPH), also known as an enlarged prostate, in adult men. BPH can cause problems such as difficulty starting urination, weak stream, and the need to urinate frequently or urgently, especially at night. Silodosin works by relaxing the muscles in the prostate and the bladder neck, making it easier to urinate and relieving BPH symptoms. It does not shrink the prostate or cure BPH, but it helps improve quality of life by reducing urinary symptoms. Key points for patients: Silodosin is not approved for use in women or children. It should be taken as prescribed, and patients should be aware of possible side effects such as dizziness or low blood pressure, especially when standing up quickly. Always inform your healthcare provider about all medications you are taking to avoid interactions.
