Product Information

Megalis is a medication prescribed for the treatment of erectile dysfunction in men. Erectile dysfunction is a condition characterized by the inability of men to get and maintain erections when sexually excited. In this medication condition, a penis has no enough blood to fill it with to expand and harden. This conditions happen to most men but it’s usually not a cause for concern.  But if it becomes bothersome, a man should see a healthcare provider.

Megalis 20 contains 20mg of Tadalafil as its active ingredient. It helps increase blood flow to the penis to help men get and keep erections for a satisfactory sexual activity.
