- The amount of time that it takes Viagra to work in any individual instance is affected by many independent variables. The dose of Viagra taken, the body mass of the man taking it, whether there is food in the stomach, whether the man has taken Viagra before and the man's body chemistry are all important factors in determining how quickly the medication will begin to work. On average, however, a man can expect Viagra to begin working somewhere between 15 minutes and 60 minutes after it is taken.
- After the medication begins to work, of course, the next important consideration is the duration during which it will last. Viagra can have lasting effects for up to 4 hours after it is taken. It is most effective, however, in the first couple of hours after its effects begin to be noticeable. For best results, then, Viagra should be taken at least 1 hour before needed and no more than 3 hours before needed.
- There's not too much that can be done to make Viagra work faster. One possibility is to ask your doctor about increasing the dose you're taking. Increasing the dose may very well help to speed the process but should only be done in concert with a doctor's recommendations. You should never take more than your prescription advises unless advised by a medical professional. It also bears mentioning that Viagra will take longer to work when taken immediately after eating.
