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. Sildenafil pills similarly come in 25mg, 50mg, and 100mg tablets.

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.

Effective treatments, trusted by over 500,000 men
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.
What does SILDENAFIL CITRATE (Generic for REVATIO) look like?
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. It's important to note that these erectile dysfunction medications aren't wonder drugs. 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? While each tablet of generic Revatio is 20mg, when used for ED, you could be prescribed multiple tablets at once, making 40mg, 60mg, 80mg, and 100mg doses possible.

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. 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.

Sildenafil is also available in the United States as a liquid solution. Your healthcare provider will tell you the specific dosage of brand-name Viagra or generic sildenafil that you should use if you’re prescribed this medication. Since brand-name Viagra tablets and generic sildenafil both contain sildenafil, you can expect identical results from a 25mg-100mg dose of Viagra (the typical doses used for erectile dysfunction) as you can the same dose of generic sildenafil. Both Viagra and sildenafil work best when taken at least 30 minutes to an hour before sexual activity (and no more than four hours beforehand).
- Sildenafil 100mg can interact with certain medications, such as alpha-blockers, possibly leading to dangerous blood pressure drops.

They only work if you're sexually stimulated. But if you’ve got sexual stimulation and these pills, research shows that you have an effective, reliable erectile dysfunction treatment. If you’re curious about the history of the brand and generic names, here’s the quick version: Two years and many clinical trials later, in March of 1998, the new medication — now called Viagra — received approval from the Food and Drug Administration and hit the market as a prescription medication for the treatment of erectile dysfunction.

Large-scale TV ad campaigns made the little blue pill famous. In 2005, the FDA approved sildenafil under the brand name Revatio® for treating pulmonary arterial hypertension — more on this later. 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 lovegra sildenafil widely available as a generic medication manufactured and marketed by various companies. Viagra is brand-name sildenafil that’s FDA-approved for ED, and what is the active ingredient in Viagra?
Sildenafil Citrate
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. 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. We’ve divided the side effects into two groups: common and rare.
- The blue sildenafil pill has helped many men regain confidence in their sexual health.
- Psychological factors can also affect erectile performance alongside medication.
- Combining medication with counseling may improve overall outcomes.
We’ve also included a note about serious drug interaction risks that you should seek to avoid and alert your healthcare provider to before taking sildenafil.
Chemical synthesis
Several pharmacies offered purple oxycodone in blister packs bearing the name of a Guatemalan drugmaker, along with a Guatemalan drug register number. None of the blister packs reporters purchased in any city tested positive for other drugs. But in Nuevo Progreso, a sealed bottle of Percocet tested positive for fentanyl. Even more troubling, in Puerto Vallarta every sealed bottle of medication reporters purchased — including four bottles of supposed Adderall and one of supposed hydrocodone — was counterfeit, testing positive for methamphetamine and tramadol, respectively. Usually, there were obvious red flags: Several had typos in their labels, and a few were entirely in English with complete American National Drug Code, or NDC, numbers.

To Felbab-Brown, the Brookings Institution cartel expert, the sophistication and prevalence of counterfeit drugs at pharmacies is reminiscent of the way Mexican criminal organizations infiltrated the fishing industry a few years ago. The Sinaloa cartel “would go to processing plants and they would say, ‘Look, we’ll burn down your plant and kill your family if you don’t sell our fish,’” Felbab-Brown explained. Other cartels copied Sinaloa’s move, and the problem spread across the country. Now, Felbab-Brown worries that something similar may be happening in Mexico’s pharmacies — and that there could be implications outside the Americas. When The Times’ initial reporting in February uncovered a counterfeiting problem on Mexico’s western coast, it was American and Canadian tourists who were most likely to be affected, she said.
What should I do if I miss a dose of sildenafil?
But because the problem is not limited to that region, it could affect a different population of visitors. “The whole Mayan Riviera is huge for European tourists,” Felbab-Brown said. “How much is this going to expose them?” In light of The Times’ findings in Mexico, she said, governments in Europe should be proactive. “They need to mount a really serious warning campaign,” she said, “as opposed to erring on the side of not informing people about a major risk.” Spontaneous sex for less than $2/day If you’ve searched the web for information about ED medication, you’ve no doubt seen Viagra® mentioned alongside a drug called sildenafil.
