Sildenafil (the active ingredient in brand-name Viagra) is approved by the FDA for erectile dysfunction and pulmonary arterial hypertension (PAH), a form of high blood pressure in the lungs. Sildenafil is in a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, or PDE5 inhibitors. Sildenafil works by blocking the actions of cGMP-specific phosphodiesterase type 5 — an enzyme that controls blood flow to certain body tissues. PDE5 regulates pfizer sildenafil 50 blood flow to your penis.

What Are the Available Sildenafil Dosages?

By blocking its effects, sildenafil improves blood supply to erectile tissue and makes it easier to get — and stay — hard. Sildenafil comes in oral tablet form and is available in a range of dosages, from 20mg up to 100mg (milligrams). It usually takes about a half-hour for sildenafil to start working. Most men who use sildenafil to treat ED take the medication 30 minutes to one hour before sexual activity. It’s recommended to avoid high-fat meals while taking this drug, which can affect its efficacy.

Drug Interactions

Since ED can vary in severity, there’s no one-size-fits-all dose of sildenafil for erectile dysfunction. If you have mild to moderate ED, you may notice major improvements in sexual performance from a relatively low dosage of sildenafil. On the other hand, if you have severe ED or erectile dysfunction caused by a medical condition that limits blood flow to your penis, you might need a higher dosage. While a higher dose of sildenafil may be most effective, taking too much sildenafil can also elevate your risk of side effects, like headache, nausea, or blurred vision. The sildenafil daily dosage for adults typically starts at 50mg, usually taken roughly one hour before sexual activity — and no more than one dose per day. If you only have mild ED, you may find that a low dosage is more than enough to improve your symptoms and help you have sex without worrying about getting or maintaining an erection. But if you have severe or persistent ED, your healthcare provider might prescribe sildenafil at a higher dosage.

As mentioned earlier, some forms of sildenafil come as a 20mg tablet. These are often generic versions of Revatio.

Engel likes to analogize erectile dysfunction to a roller coaster. Typically, there is a slow movement toward ED. However, once erectile dysfunction begins interfering with sexual activity, it is a downward slope that generally cannot be reversed.

However, the underlying vascular issues associated with ED typically worsen with age, and there’s simply nothing we can do about it.

How does sildenafil work (mechanism of action)?

As such, eventually, these drugs will no longer offer satisfying erections, at which point we need to consider further treatments, including injections or penile prostheses (implants).

Though it’s a great drug, taking too much or too little can either render it ineffective or set you up for some uncomfortable side effects.

What the drug does do is make it easier to get and maintain an erection when you’re already sexually aroused. But here’s the thing — if you don’t get the dosage right, the medication probably won’t work the way it should. Below, we’ll explain how to find the right sildenafil dosage for ED, what you should know about sildenafil dosage timing, and why you should never exceed the maximum dose of sildenafil in 24 hours. Like many other medications for ED, sildenafil helps you get and maintain erections by increasing blood flow to the tissue inside your penis. But sildenafil dosage isn’t based on penis size, SAT scores, your tax bracket, or how badly you want to elevate your sex life. When sildenafil is used with these or other medications for hypertension or cardiovascular disease, it can contribute to a sudden decrease in blood pressure that may, in some cases, be life-threatening.
