The dosages for Sildenafil are 25 mg, 50 mg, and 100 mg. The dosage recommended would depend on the age, health, ailment, and how well you will respond to your drugs. 

If you have a history of heart attacks or suffer from other cardiovascular problems, you should take a lower dosage of the drug. This is a precautionary step to ensure that there is no adverse effect on taking the drug.
