The side effects of Super Fildena, a dual-action medication containing sildenafil and dapoxetine, can vary in duration depending on the individual’s metabolism, age, dosage taken, and overall health. Common side effects such as headache, flushing, dizziness, nasal congestion, or mild nausea usually subside within a few hours—typically 4 to 6 hours after the medication’s peak effect. However, side effects like dry mouth, upset stomach, or light sensitivity may persist slightly longer. Dapoxetine, being a short-acting SSRI, may cause transient mood changes or insomnia that can last up to 12–24 hours. Severe side effects like prolonged erection (priapism) or chest pain require immediate medical attention, as their duration and consequences can be serious if left untreated. Hydration, rest, and avoiding alcohol can help reduce side effect severity and duration. If side effects last beyond 24 hours or worsen, a healthcare provider should be consulted immediately.
