However, individual responses may vary, and the duration of action can depend on factors like metabolism and overall health. It's essential to follow the dosing instructions provided by your healthcare provider and use Malegra or any Sildenafil medication only under medical supervision.

If you have concerns or questions about Malegra or its duration of action, consult a healthcare professional for personalized advice and guidance.
