Never take more than 100 mg of Viagra in a 24-hour period. Too much Viagra can cause severe headache, low blood pressure, and orthostasis (drop in blood pressure when standing) that can lead to fainting. Higher doses can also cause priapism, a painful erection that lasts longer than 4 hours.
Because 100mg is the highest dose available, you should never 'double up' on tablets or take more than one in 24 hours. Sildenafil 100mg is the highest safe dosage you can take – if it is ineffective, you should try another ED treatment.

The effects of taking 100 mg of Viagra can last for up to 4 hours after taking the drug. However, the strength of these effects is weaker at 4 hours than 2 hours after taking Viagra. As the concentration of Viagra in the blood typically peaks 60 minutes after taking the drug, the effects are strongest around this time.
Sildenafil has a 4-hour 'half-life', meaning half of the drug has left the bloodstream after 4 hours. Some men may still be able to achieve a satisfactory erection after 10 hours, although the duration will become shorter. After 24 hours all traces of the drug in the bloodstream has practically gone.

Taking More than the Recommended Dose of Sildenafil
Actually, not at all. While you may think that taking more than your prescribed dose of sildenafil could increase the firmness of your erection or make you last longer, that's not true. In fact, it could just increase potential side effects.
Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.
Generic Viagra, or sildenafil citrate, works the same as Viagra, but at a lower cost. While Pfizer still manufactures the “little blue pill,” other companies, globally and in the United States, make sildenafil. It may look different, but it's still an effective treatment for ED.
While rare, Viagra can cause an erection that lasts longer than 4 hours (priapism). This can result in permanent damage if left untreated. Vision changes are also possible.
In healthy volunteers, sildenafil doses are absorbed rapidly, with maximum plasma concentrations achieved within a median time of 1 h (range, 0.5–2 h) after dosing [3].
Typically, an average erection may last from a few minutes to roughly half an hour. However, this can vary significantly due to the many factors that can affect erection duration. It is also worth noting that a person does not need an erection to achieve orgasm.
Minor differences in packaging aside, brand name Viagra and its generic counterpart sildenafil are exactly the same medication. If you have erectile dysfunction, both medications should produce noticeable improvements in your erections and sexual performance. The key difference, as we mentioned above, is price.

Speak with your healthcare provider about a different dose
If Viagra isn't working for you, you might need a higher dose. But don't experiment on your own: Always speak with a healthcare provider about dosage changes and never take more than one dose of Viagra in any 24 hour period.
Nothing much would happen if someone without erectile dysfunction took Viagra, although they might think they feel better psychologically. But it would make a difference if you took it along with other drugs.
Even though the effects of Viagra won't last longer than 12 hours, it takes 24 hours to make sure it's safely out of your system. Taking more than one Viagra in the same 24 hour period could mean the amount of Viagra in your body builds up to unsafe levels.
