Avoid taking Viagra with a large meal or high-fat meal
Viagra blood levels peak an hour after you swallow the tablet on an empty stomach. According to Ramin, if you eat a large or high-fat meal and then take Viagra, the medication will lose its effectiveness and may take longer to start working.

Viagra contains the drug sildenafil. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. (A class of drugs is a group of medications that act in a similar way.) Viagra works by increasing blood flow to your penis, which helps you have and keep an erection.

An increase in sildenafil dose from 50 mg to 100 mg was associated with a higher proportion of completely hard and fully rigid erections and a higher rate of SSI during the initial attempt using the higher dose, improvements that were statistically significant in the larger study.

50mg is the standard starting dosage for sildenafil (Viagra).
