Nowadays, many manufacturers continue to make sildenafil as a blue-coloured pill, but it also comes in a variety of other shapes and colours, and is sometimes manufactured as a white pill.

12.1 Mechanism of Action

The other important factor in pricing is competition: as sildenafil is widely available for manufacture, the price is more competitive (and therefore cheaper). A 2019 study was conducted into the effectiveness of generic medication, which found that there was no difference between how generic and brand-name medication works. Even though generic sildenafil is unbranded, it is still an effective treatment for ED and works in the same way as Viagra. Both Viagra and sildenafil are considered effective treatments for ED. The colour and shape of the pill have no impact on how effective the treatment is.

Are you currently using Sildenafil (Viagra, Revatio)?

The main difference between generic medication, such as sildenafil, and brand-name medication, such as Viagra, is the purchase price and the appearance of the pill. Generic for Viagra ® contains Sildenafil, a doctor-trusted ingredient that is effective for treating ED, which means that it is just as effective for the treatment of erectile dysfunction as the original ED medication. Generic Viagra® is a PDE5 (phosphodiesterase type 5) inhibitor, which works by blocking the PDE5 enzyme, which in turn temporarily relaxes smooth muscle and improves blood flow to the penis during sexual stimulation. While Viagra® is easily recognizable as the “little blue liquid sildenafil citrate pill,” the generic for Viagra® comes in many different colors and shapes. Authentic pills may be white or blue, round or diamond, etc. This is commonplace, and, as with many types of generic medication, you may find that the appearance of your pills sometimes changes each time you order them. However, don’t worry; the active ingredients and effectiveness of the treatment remain the same. The main difference between sildenafil and Viagra is that Viagra is branded, and sildenafil is the generic, or unbranded, version of it. As both sildenafil and Viagra contain the same active ingredient, sildenafil citrate, they are both effective treatments for men with ED. All generic medication has to contain the same active ingredient to ensure it works in the same way as its brand-name equivalent. Branded medication is often more expensive than generic medication. Any new brand-name medication will pitch the price relative to the amount of initial research needed to develop and prepare the treatment for marketing approval. Generic medication can typically be 20-90% cheaper than its brand-name equivalent because of this.

A 2019 study was conducted into the effectiveness of generic medication, which found that there was no difference between how generic and brand-name medication works.

Other Interactions

When Viagra® was approved as a treatment for erectile dysfunction in 1998, it was marketed as the “little blue pill.” You may remember those early ad campaigns starring Bob Dole or the ones where men in suburbia jumped for joy because they’d finally found a solution for their problems in bed. Though Viagra (the brand name for sildenafil citrate) was the first FDA-approved ED medication, many others followed in its wake, including Cialis® (tadalafil), Levitra® (vardenafil), and Stendra® (avanafil). These drugs worked similarly sildenafil generic to Viagra, but they didn’t come in a blue pill. There are other blue medications, but they’re nothing like Viagra. For instance, counterfeit pills that contain the opioid fentanyl or other substances can come in a blue tablet, and mistaking it for Viagra can have dire consequences for your health. The cost of a generic for Viagra® tablet varies based on the strength of the dose of sildenafil it contains, but generally costs anywhere from about $4 to $10 per dose, compared to $50 to $70 per dose for brand-name Viagra®.

Route of administration

To access the medication without a prescription, they may turn to illegal drug sellers and online pharmacies, which are infamous for selling counterfeit prescription drugs. Some counterfeit ED medications have been found to contain inconsistent doses of the active ingredient and contaminants like talcum powder, commercial paint, and printer ink. Even worse, these pills may also include other hidden drugs, including opioids. For instance, in 2022, a Louisiana man was arrested for illegally possessing a large amount of narcotics with the intent to sell, including 610 pills of suspected Viagra. When the pills were sent to the lab for testing, they were found to contain over 28 grams of fentanyl.

What should I do if I accidentally use too much sildenafil?

Fentanyl is a synthetic opioid that is 100 times more powerful than morphine and 50 times stronger than heroin. According to the Drug Enforcement Administration (DEA), two out of every five fake prescription pills with fentanyl contain a potentially lethal dose. And even if you’re lucky, and you do get your hands on some genuine Viagra, it’s still not safe to take the medication unless you’ve consulted with a medical provider. While Viagra has a solid safety record and is generally well-tolerated, the medication may not be safe for you if you have a medical condition like heart disease or heart failure, or if you’re taking medication for high blood pressure. The Generic for Viagra ® is called Sildenafil Citrate. This means that the generic form of Viagra ® will have the same therapeutic effect, but at a lower cost Yes, generic forms of Viagra® are just as safe as Viagra®.
