Oral Administration

Taking too much sildenafil can cause unpleasant side effects. Talk to your doctor if you take too much sildenafil and you're worried about any of these side effects: Sildenafil is a vasodilator, which will relax blood vessels and increase blood flow to lungs and other specific organs.

Sildenafil may also be used off-label to treat: Raynaud phenomenon (narrowing blood vessels in extremities such as fingers and toes) Raynaud phenomenon (narrowing blood vessels in extremities such as fingers and toes) Sildenafil has a variety of uses because it’s a phosphodiesterase type 5 (PDE5) inhibitor. PDE5 inhibitors are medications that improve blood flow to certain tissues by widening the blood vessels. They’re best known for increasing blood flow to the penis, allowing for erections upon sexual stimulation. At the moment, 20 mg Viagra does not exist — but you can get Revatio in a 20 mg tablet, and it can be prescribed off-label for ED. In the same way that you can 200mg sildenafil citrate get generic Viagra as a 25 mg sildenafil tablet, you can also get generic Revatio as a 20 mg sildenafil tablet. It may be marked as a c89 pill or described as generic Viagra because these drugs both contain sildenafil. The only chemical difference is the dosage. If you’re taking a 20 mg generic Viagra white pill, chances are you’re actually taking generic Revatio. Viagra is available in dosages of 25 mg, 50 mg, and 100 mg. Currently, 100 mg sildenafil is the highest dosage approved by the FDA.

Revatio is available in 20 mg tablets. There’s no one-size-fits-all solution when it comes to the ideal sildenafil dosage.

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. 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. 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. If you find that a particular 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. If you take a 20 mg dose of sildenafil, it might improve your erections, but it might not.

5.3 Effects on the Eye

But when it comes to erectile dysfunction (ED) medications, dose size can make a difference. 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. With that said, other erectile dysfunction treatments — like tadalafil (Cialis®) and vardenafil (Levitra®) — are available in a 20 mg dosage, but these are different medications, so their dosages aren’t directly comparable to sildenafil. Whether you’re experiencing poor erectile function or have a cardiovascular condition, sildenafil can drastically improve your symptoms. The medication is generally safe, and research suggests it won’t cause any long-term health issues. But that doesn’t mean it’s completely without risks or side effects. If you experience priapism (a prolonged, painful erection) or any other serious adverse effects — like shortness of breath, irregular heartbeat, or loss of vision — seek emergency medical attention. Sildenafil might also be dangerous for people with a history of certain medical conditions, including: Allergic reactions to Viagra or any PDE5 inhibitor Allergic reactions to Viagra or any PDE5 inhibitor Blood problems like hemophilia, leukemia, or sickle cell anemia Blood problems like hemophilia, leukemia, or sickle cell anemia Conditions affecting penis shape, like Peyronie’s disease or a curved penis Conditions affecting penis shape, like Peyronie’s disease or a curved penis Eye problems, such as retinitis pigmentosa, vision loss, or NAION (non-arteritic anterior ischemic optic neuropathy) Eye problems, such as retinitis pigmentosa, vision loss, or NAION (non-arteritic anterior ischemic optic neuropathy) Heart problems (e.g., having had a heart attack or stroke) Heart problems (e.g., having had a heart attack or stroke) There are a few sildenafil drug interactions you need to look out for, too. An interaction is when one drug, like sildenafil, causes a negative reaction when mixed with another medication, supplement, or substance.

• Sildenafil does not cause spontaneous erections; stimulation is still required.
• Avoid using it if you have a history of stroke or severe heart disease.
• Consult a doctor especially if you have kidney or liver problems.
• The medication should not be used with certain antidepressants or antibiotics.
• Excessive dosing can lead to serious cardiovascular events.

Other PDE5 inhibitors, including erectile dysfunction medications like tadalafil (Cialis), avanafil (Stendra®), or vardenafil (Levitra or Staxyn®) Other PDE5 inhibitors, including erectile dysfunction medications like tadalafil (Cialis), avanafil (Stendra®), or vardenafil (Levitra or Staxyn®) Nitrates for angina (chest pain), such as nitroglycerin (Nitrostat® or NitroMist®), isosorbide mononitrate, and isosorbide dinitrate (Isordil®) Nitrates for angina (chest pain), such as nitroglycerin (Nitrostat® or NitroMist®), isosorbide mononitrate, and isosorbide dinitrate (Isordil®) Sildenafil may also have minor interactions with the following substances: Certain antifungal drugs, such as ketoconazole and itraconazole Certain antifungal drugs, such as ketoconazole and itraconazole Some antibiotics, like erythromycin and clarithromycin (Biaxin®) Some antibiotics, like erythromycin and clarithromycin (Biaxin®) HIV protease inhibitors, like saquinavir mesylate (Invirase®) and ritonavir (Norvir®) HIV protease inhibitors, like saquinavir mesylate (Invirase®) and ritonavir (Norvir®) If you’ve been prescribed any of the above medications, it’s a good idea to ask a healthcare professional whether you can safely take them with sildenafil.
