Supplementary information

Sildenafil citrate is a generic drug found in several types of prescription meds. It’s most popularly known as the active ingredient in Viagra® and a treatment for ED, but sildenafil is also sold as Revatio®, a medication marketed for treating pulmonary arterial hypertension. Depending on your health needs, your dosage of Viagra might be 25 milligrams (mg), 50 mg, or 100 mg. While sildenafil 20 mg tablets do exist, they’re FDA-approved for pulmonary arterial hypertension, not ED. Keep reading to find out if a sildenafil 20 mg dosage for erectile dysfunction exists, the most common sildenafil dosages, potential side effects, and more.

Mechanism of Action

Most people assume they know what Viagra does — it causes erections, right? While this is true, a few uses of sildenafil extend beyond improving sexual activity. Besides being sold as Viagra, sildenafil is the active ingredient in Revatio. As we mentioned above, this brand-name drug is approved by the U.S. Food and Drug Administration (FDA) for treating pulmonary hypertension, a type of high blood pressure affecting arteries in the lungs and the right side of the heart. Revatio is available in 20 mg tablets. There’s no one-size-fits-all solution when it comes to the ideal sildenafil dosage. Your dosage will depend on your health needs and the reason you’re taking the medication.

You might assume a higher dosage of sildenafil leads to a firmer erection or better sex, but this isn’t always the case. In fact, taking too much sildenafil can lead to some serious side effects, like a sudden decrease in blood pressure. It’s best to stick with your prescribed dosage and follow the patient information leaflet your healthcare provider gives you.

• Common side effects include headaches, flushing, and nasal congestion.
• Rarely can cause vision changes, such as blurred vision or color tinge.
• Serious side effects require immediate medical attention.

If you find that a particular sildenafil 100mg hexal dose isn’t working as well as you had hoped, make another appointment with your provider and ask if you can revisit your dosage or explore other treatment options. To get the best results from Viagra, it’s important to take the right dosage.

As mentioned, 20 mg sildenafil is FDA-approved for pulmonary arterial hypertension, not erectile dysfunction.
