Drugs not to take with Viagra

What is the ideal dosage power for Viagra?

Viagra should only be taken once a day even though the effects wear off after approximately 4-5 hours. A Viagra pill or tablet of 50 mg, is taken approximately 1 hour before sexual activity (although can be taken from 30 minutes to 4 hours before). 

The dose may be increased to 100mg if 50mg is ineffective or decreased to 25mg if side effects are intolerable. However, one should always consult a doctor before finalising on his daily dose intake.
