If you are experiencing the symptoms of erectile dysfunction (ED), you may have considered using Viagra or a similar ED medication as a possible treatment.
But if you’ve searched for places to buy Viagra online, you will have no doubt noticed its price tag, too. Since Viagra is a brand-name medication, the price of Viagra is very high and may not currently work within your budget.
While some of what’s sold as generic Viagra online is fake, several reputable companies sell sildenafil online. Each of the companies below has been vetted by our team for medical and business standards. Learn more here.
Sildenafil citrate (sildenafil), often referred to as “generic Viagra,” is the same active ingredient used in Viagra. Viagra also contains small amounts of inactive ingredients. These ingredients give the pill its form and make it easier for your body to metabolize them.
One of the primary causes of ED is a buildup of the phosphodiesterase type 5 (PDE5) enzyme that restricts blood flow to the penis and prevents or lessens the firmness of an erection. Sildenafil works as a PDE5 inhibitor, which blocks the effect of PDE5 and allows more unrestricted blood flow — making an erection more likely.
Instead of the “little blue pill,” as Viagra is known, sildenafil is often sold as a little white pill by Viagra’s competitors. The pill’s appearance does not change its effectiveness or how it works in the body.
While generic sildenafil and Viagra are equally safe and effective, the medications have one key difference: price. Viagra costs around $60–$70 per tablet. Generic sildenafil can range from $2–$18 per pill, depending on the manufacturer and dose.
The pharmaceutical giant Pfizer discovered the ED benefits of sildenafil by accident.
Researchers were testing the medication to treat high blood pressure and angina — chest pain associated with heart disease. They found that the medication was especially effective at inducing erections. The Food and Drug Administration (FDA) approved Viagra in 1998, making it the first oral drug specifically prescribed for ED.
Pfizer was also the first to introduce generic Viagra through a subsidiary called Greenstone. Other companies around the world also manufacture sildenafil pills, including:
•Teva Pharmaceuticals
•Aurobindo
•Cambia
Sildenafil is best known as a treatment for ED, the inability to get or keep an erection. Sildenafil is meant to be taken before having sex, with the understanding that its effects last only a few hours.
Sildenafil is also approved for treating PH. Revatio is the brand name of sildenafil prescribed for PH. It’s worth noting that while Revatio and Viagra have the same active ingredient, Revatio is FDA-indicated for treating PH specifically and you shouldn’t take Revatio instead of Viagra or alongside Viagra to treat ED.
Generic Viagra (sildenafil) is available as a 20-, 25-, 50-, and 100-milligram (mg) pill and in liquid form. It’s meant to be taken as needed — about an hour before sex — but shouldn’t be taken more than once per day. The 50-mg dose is standard, though your doctor may start you on a 25-mg dose to see if that’s enough.
Serious side effects of sildenafil
More serious side effects should prompt an immediate call to your doctor or 911. They include: •erection that is painful or lasts longer than 4 hours (priapism) •blurry vision or sudden and severe loss of vision •diminished hearing •ringing in ears •dizziness or lightheadedness •fainting •shortness of breath •chest pain •itching or burning during urination •rash
Blood pressure and heart medications
One of the most serious interactions can come from combining PDE5 inhibitors with nitrates or compounds containing nitrates. Several studies, including a 2018 study, show that using PDE5 inhibitors with nitrates is a contraindication that can cause a life-threatening drop in blood pressure. This is why you should discuss any medications that you’re taking with your doctor before starting any new medication. This can reduce the chances of a dangerous interaction. If you take other medications for high blood pressure, you may be at risk of experiencing a dangerous drop in blood pressure. These include: •diuretics •angiotensin-converting enzyme (ACE) inhibitors •calcium channel blockers A drop in blood pressure can result in: •dizziness •headache •fainting or falling Severe blood pressure drops can also result in less oxygen moving through your organs.
Other ED medications
Avoid taking sildenafil with any other ED medications. The combination can lower blood pressure, causing fainting, dizziness, and in some rare cases, heart attack.
Alcohol
Alcohol and sildenafil can combine to lower blood pressure too much. Avoid alcohol if you’re taking sildenafil.

May 14, 2024 · Viagra has a drug half-life of four hours. This means that 50% of the drug will be cleared from your system after four hours. Thereafter, the concentration of the drug will continue to drop by half every few hours until no drug is left in the system—usually within 16 to 24 hours. This does not mean that Viagra will work for 16 to 20 hours.
