Eriacta is a medication containing sildenafil citrate, prescribed for the treatment of erectile dysfunction (ED). It functions as a PDE5 inhibitor, working to increase blood flow to the penis following sexual stimulation to facilitate an erection. The effects of Eriacta typically last for 4-6 hours. To ensure safe and appropriate use, a prescription from a healthcare professional is necessary to determine the correct dosage and screen for potential contraindications.
