Drug Class: Phosphodiesterase type 5 (PDE5) inhibitor

Fildil is a prescription medication containing tadalafil. It is used to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH) in adult men. Tadalafil works by relaxing blood vessels and increasing blood flow to specific areas, helping improve erectile function and support urinary symptoms associated with BPH.

One of the distinguishing features of Fildil (tadalafil) is its extended duration of action — up to 36 hours, giving users greater flexibility compared to shorter-lasting ED medications. Fildil may be taken as needed before sexual activity or as a daily low-dose regimen, based on your doctor’s recommendation.

Use Fildil only under medical supervision.
