I take dinner at around 8 P.M.,what should be the right time to take 50mg VIAGRA & have maximum effe

Mr. Patel - A review of some of the literature suggests that taking it on an empty stomach is most effective and that high fat meals can interfere with the effectiveness of Viagra, so you may want to avoid those. Viagra has been shown to be effective for up to 4 hours but its effectiveness appears to begin to decrease after about 2 hours. It appears that allowing approximately 1 hour after taking it will typically give the best result. Since Viagra can lower blood pressure taking it with an antihypertensive medication should always be done with your physician's knowledge and approval.
