Always consult your doctor before using Viagra, especially if you have heart problems, high or low blood pressure, or liver or kidney disease. Your doctor will assess your health and determine the appropriate dosage, if any.
Viagra should be taken only as directed. The recommended starting dose is 50mg, taken about one hour before sexual activity. Never exceed the maximum recommended dose of 100mg in a 24-hour period. Avoid grapefruit juice, as it can interact with Viagra and increase its effects.
