Penegra 50 mg is another medication used to treat erectile dysfunction, containing the active ingredient sildenafil citrate, which works by increasing blood flow to the penis during sexual stimulation. Like other medications in its class, such as Suhagra and Viagra, Penegra is generally taken orally as needed, approximately 30 minutes to 1 hour before sexual activity. Regarding food interactions, similar advice applies to Penegra as to other sildenafil-based medications. It's typically recommended to take Penegra on an empty stomach or with a light meal. Consuming a heavy or high-fat meal right before taking Penegra may delay its onset of action, as fatty foods can slow down the absorption of the medication into the bloodstream.
