The compound is effective in improving erectile function and is typically taken orally, with effects lasting several hours. It may also be prescribed for certain cases of benign prostatic hyperplasia (BPH), as it can improve urinary symptoms associated with the condition. Vardenafil hydrochloride trihydrate is designed for on-demand use, usually taken about 25 to 60 minutes before sexual activity, and its efficacy can be influenced by food intake.
