The effects of Extra Super P Force typically last for about 4 to 6 hours after administration. However, the duration of action may vary depending on individual factors such as metabolism, age, and overall health. It's generally recommended to avoid consuming alcohol while taking Extra Super P Force, as alcohol can increase the risk of side effects such as dizziness, drowsiness, and lowered blood pressure. Additionally, consuming a heavy meal high in fat content may delay the onset of action of sildenafil citrate, so it's advisable to take Extra Super P Force on an empty stomach or with a light meal.
