Formulated as that iconic little blue pill, Viagra has the longest history of any FDA-approved ED treatment on the market today. Both generic sildenafil and Viagra work by increasing blood flow to your penis, making it easier for you to get and maintain an erection. Sildenafil belongs to a class of enzyme-inhibiting drugs called phosphodiesterase type 5 inhibitors, or PDE5 inhibitors. Like the others in its class, sildenafil works by relaxing the muscle tissue inside the walls of your blood vessels, allowing the vessels to dilate, and improving blood flow throughout some parts of your body — including your penis.

Pfizer’s patent on Viagra expired in 2012 for countries outside the U.S., allowing other brands to produce and market their own generic Viagra medications containing sildenafil. Although Pfizer challenged the expired patent in the United States, sildenafil has since become widely available as a generic medication manufactured and marketed by various companies.

But we suspect the question you really want to ask is whether one is made better, or safer — is generic sildenafil as good as Viagra for treating ED? Although some manufacturers may use their own brand name, most generic sildenafil products are labeled simply as “sildenafil.” Regardless, they do the same thing, offer the same benefits, and have the same risk of side effects. While a single tablet of Viagra is priced as high as $70 in the United States, generic drugs like sildenafil tablets are available for as little as $3 each when purchased online.
Uses for Viagra
Viagra. Put simply, Viagra is the FDA-approved brand-name version of sildenafil, a prescription medication for ED. Sildenafil is the main active ingredient in Viagra. Like the store-brand salad dressing made with the same ingredients as its brand-name equivalent, sildenafil is just as good as the “little blue pill,” but cheaper. Keep reading to learn more about the similarities and differences between these drugs, and how to choose the best one for you. Even though the active ingredients are the same, if you’re switching from Pfizer’s brand-name Viagra to a generic form of sildenafil, it’s important to check that you’re purchasing tablets with a similar dosage to the one your healthcare provider prescribed. Sildenafil may also be sold under different brand names in other countries. Some of these Viagra generic names include: When it comes to drugs like Figral, Mazzogran, and Fildena vs. Viagra, they are all used for the same purpose: increasing blood flow to the penis.
What other drugs will affect sildenafil?
Sildenafil citrate (often shortened to “sildenafil”) is the main ingredient in Viagra. After parent company Pfizer’s patent expired, other manufacturers were allowed to manufacture generic Viagra under the name of its active ingredient, sildenafil. The terms are pretty much interchangeable, the way you might say “Kleenex®” to refer to a tissue. The only real difference between the two medications for ED is how much they cost. Viagra® is a well-known and widely used medication for treating erectile dysfunction (ED), one of the most common sexual dysfunctions in the world. Their labels also state that these products contain sildenafil, so Mazzogran sildenafil 100mg should be equivalent to brand-name Viagra 100mg. However, because these drugs have not been made in the U.S. and cleared by the FDA, it may be harder to assess the quality of their ingredients. Each country has its own set of regulations, and there’s always the chance the product you’re getting is not authentic if you buy it online from an international retailer. If you’re in the U.S. and looking for a cheaper alternative to Viagra, it’s best to stick with FDA-approved sildenafil. Viagra comes in three dosages: 25mg, 50mg, and 100mg.
How to save on sildenafil citrate
There have been reports of heart attack, stroke, irregular heartbeat, bleeding in the brain or lungs, high blood pressure, and sudden death in men who took sildenafil for erectile dysfunction. Most, but not all, of these people had heart problems before taking sildenafil. It is not known whether these events were caused by sildenafil, sexual activity, heart disease, or a combination of these and other causes. Talk to your doctor about the risks of taking sildenafil. Some patients experienced a sudden decrease or loss of hearing after they took sildenafil or other medications that are similar to sildenafil.

It is not known if the hearing loss was caused by the medication. If you experience a sudden loss of hearing, sometimes with ringing in the ears or dizziness, while you are taking sildenafil, call your doctor immediately. If you are taking sildenafil (Viagra) for erectile dysfunction, do not take any more doses of sildenafil (Viagra) or similar medications such as tadalafil (Cialis) or vardenafil (Levitra) until you talk to your doctor. If you are taking sildenafil (Liqrev, Revatio) for PAH, do not stop taking your medication until you talk to your doctor. Call your doctor if you have any unusual problems while you are taking this medication. Sildenafil pills similarly come in 25mg, 50mg, and 100mg tablets. However, sildenafil can also come in 20mg when it is sold as the generic version of Revatio. Revatio is FDA-approved to treat a type of high blood pressure in the lungs (called pulmonary arterial hypertension, or PAH), but it can be prescribed off-label for ED.So, is sildenafil 20mg the same as Viagra 25mg?
