Available in tablets, Viagra operates on the muscles in the penis. When the muscles get elongated, more blood reaches the penis, which gives it a hard erection. The more the blood flow, the greater will be the erection.

Viagra can be used after taking food or even without food. Take Viagra pills just an hour before you en gage with your partner. The normal Viagra dose for adults is 50 milligram. But for elderly persons, particularly those who have crossed 65, the doctors advise only 25 mg of the impotency drug.

When taking Viagra, never use more than one tablet at a time. Moreover, always have a gap of twenty fours between two tablets of Viagra.

Always consult the doctor if you have impotency issues and do not go for any erectile deficiency drugs of your own. Once you consult the physician make sure that he has an overall picture of your health. The doctor needs to know about your health as he can only prescribe the right dosage after that.

Always be frank to tell the doctor if you are suffering from any heart problems, kidney or liver issues and blood related diseases
