6.1 Clinical Trials Experience

Taking an excessive dose of Viagra may result in a sudden drop in blood pressure, which could cause fainting. It’s important to make sure you don’t take more than the amount prescribed sildenafil citrates by your healthcare provider. If you’ve accidentally consumed more than the maximum safe dose of Viagra, it’s important to seek immediate emergency medical attention. Viagra and sildenafil both contain sildenafil, meaning you can use the same dose regardless of which medication you choose to take. Not only do sildenafil and brand-name Viagra work the same way, but they also cause the same potential side effects, interactions, and allergic reactions.

How should I store sildenafil?

The exception to this is if your sildenafil is actually the generic version of Revatio, which comes in 20mg tablets. Revatio is FDA-approved to treat PAH, but it (and its generic) are sometimes used off-label for ED. Taking a larger dose of Viagra than prescribed can be dangerous and isn’t recommended. Any Viagra dose higher than what you’re prescribed could increase your risk of potentially harmful side effects and drug interactions. For instance, 200mg Viagra doses and higher could cause serious side effects, such as priapism (a painful, prolonged erection), vision loss in one or both eyes, hearing loss, and hypotension (low blood pressure).
