Eriacta is a generic medication containing sildenafil citrate, prescribed for the management of erectile dysfunction (ED). As a phosphodiesterase type 5 (PDE5) inhibitor, it functions by enhancing the natural erectile response to sexual stimulation. The medication works by increasing blood flow to the penis, facilitating the ability to achieve and maintain an erection firm enough for sexual activity. Eriacta does not cause an automatic erection and requires sexual arousal to be effective. It is typically taken 30 to 60 minutes before intercourse, with a duration of action of approximately 4 to 6 hours. Common side effects include headache, facial flushing, and indigestion. It is absolutely contraindicated for use with any nitrate-based medications due to the risk of a severe and life-threatening drop in blood pressure. A thorough medical evaluation is necessary to ensure it is a safe and appropriate treatment choice.
