Addressing Performance Anxiety and Erectile Function

If you ever forget to take Viagra, you'll probably notice it — regretfully — immediately.

How oral medicines differ

May benefit from Viagra to treat ED May benefit from Viagra to treat ED Have no health issues that could make Viagra unsafe Have no health issues that could make Viagra unsafe Aren’t using any medications that could interact with Viagra Aren’t using any medications that could interact with Viagra Viagra may cause drug interactions if you take other medications, such as riociguat or nitrates for chest pain, heart disease, or other cardiovascular issues. When used at the same time, these medications can cause a sudden decrease in blood pressure levels that may, in some cases, be life-threatening. A similar reaction can occur with nitrites, found in recreational drugs known as “poppers.” Some medications, such as ritonavir, ketoconazole, itraconazole, and erythromycin, can affect your body’s ability to properly absorb and metabolize Viagra. Viagra can also cause health problems for people with certain medical conditions, like high blood pressure, cardiovascular disease, heart failure, previous heart attacks, leukemia, multiple myeloma, and sickle cell anemia. Viagra is prescribed for use as needed before sex, meaning there’s no such thing as “missing” a dose. That said, missing a dose of Viagra won’t have any long-term negative effects on your erections or sexual function nor will it affect your health in any way. Viagra, as well as its generic equivalent, sildenafil, is an easy-to-use medication that makes getting and maintaining an erection a much simpler process.

We cover this topic in more detail in our guide to how long Viagra and other ED medications last. Sildenafil, the active ingredient in Viagra, has a half-life of four hours, meaning it takes four hours for your body to metabolize half the medication. This half-life doesn’t change at a lower dose, meaning even a single dose of Viagra at 25mg should last about four hours, although the total concentration in your blood will be lower than if you took a higher dose.

However, taking Viagra with a large, high-fat meal may slow down the absorption of this medication, meaning it could take a little longer before you start feeling its effects. Viagra is safe and effective for most men with ED. But like all medications, it can cause side effects. Our guide to Viagra side effects goes into more detail about various adverse effects and drug interactions that you should be aware of when using either brand-name Viagra or generic sildenafil. Taking an excessive dose of Viagra may result in a sudden drop in blood pressure, which could cause fainting.

How much Viagra should I take the first time?

It’s important to make sure you don’t take more than the amount prescribed 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. The exception to this is if your sildenafil is actually the generic viagra online generic version of Revatio, which comes in 20mg tablets.

What would happen if I took a larger dose of Viagra than my doctor prescribed — for example, 150 mg or 200 mg?

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). Your healthcare provider will only prescribe Viagra if you’re a good candidate for it.
