Yes, generic Viagra is widely available in the United States. The FDA first approved a generic version of Viagra (sildenafil citrate) in 2016, and more than a dozen manufacturers now produce it. The result has been a dramatic drop in price, making the medication far more accessible than the brand-name version.
How Generic Sildenafil Became Available
Pfizer’s patent on Viagra expired in 2012, but a settlement with generic manufacturer Teva delayed the first generic launch until December 2017. Teva had actually received FDA approval back in March 2016, making it the first company cleared to produce generic sildenafil for erectile dysfunction. By mid-2018, several more manufacturers entered the market, and as of early 2025, at least 16 companies hold FDA approval to make the drug.
The flood of competition had a staggering effect on pricing. Between December 2017 and June 2021, the list price for six tablets of 100 mg generic sildenafil fell by 98%, dropping from $265 to just $4. Over that same period, the list price for the equivalent brand-name Viagra actually rose 27%, from $369 to $467.
Cost: Generic vs. Brand-Name
The price gap between generic sildenafil and brand-name Viagra is enormous. Generic sildenafil costs as little as 44 cents per 50 mg dose when purchasing 30 pills, which works out to about $13 for a month’s supply. The equivalent brand-name Viagra pills cost at least $67 each, or roughly $2,014 for the same 30 tablets. That’s a markup of more than 40 times.
Pharmacy discount coupons from services like GoodRx can push prices even lower. In one pricing comparison, six tablets of 100 mg generic sildenafil cost $9.47 at a supermarket pharmacy with a free coupon, while the cheapest available price for the same amount of brand-name Viagra was over $400.
Available Strengths and How It’s Taken
Generic sildenafil for erectile dysfunction comes in the same three tablet strengths as brand-name Viagra: 25 mg, 50 mg, and 100 mg. Most prescriptions start at 50 mg, taken about one hour before sexual activity. The dose can be adjusted up to 100 mg or down to 25 mg depending on how well it works and whether side effects occur. People over 65 or those with liver or kidney issues typically start at the lower 25 mg dose. It should not be taken more than once in a 24-hour period.
One important distinction: sildenafil is also sold under the brand name Revatio for treating a lung condition called pulmonary arterial hypertension. Revatio tablets come only in a 20 mg strength and are taken three times daily, which is a completely different dosing pattern. If you’re filling a prescription for erectile dysfunction, make sure the pharmacy dispenses the correct product and strength.
Is It the Same as Brand-Name Viagra?
Generic sildenafil contains the same active ingredient in the same amount as brand-name Viagra. To earn FDA approval, each generic manufacturer must demonstrate bioequivalence through a clinical study comparing how the drug is absorbed in the body versus the brand-name version. The FDA requires a single-dose crossover study in healthy male subjects, measuring blood levels of both sildenafil and its active breakdown product. If the generic performs within a tight statistical range of the original, it’s approved.
Once a manufacturer proves bioequivalence at the 100 mg strength and passes dissolution testing (which confirms the tablet breaks down properly), the FDA waives the need for separate studies on the 25 mg and 50 mg strengths, as long as the formulations are proportionally similar. In practical terms, you can expect the same effectiveness and side effect profile from a generic as from brand-name Viagra.
Insurance Coverage Is Limited
Despite the low cost of generic sildenafil, insurance coverage for erectile dysfunction medications remains spotty. Medicare Part D plans do not typically cover sildenafil for ED because the drug is not classified as medically necessary under their guidelines. Medicaid hasn’t covered erectile dysfunction drugs at all since 2005. Some Medicare Advantage (Part C) plans may help cover generic versions, but this varies by plan.
Private insurance is similarly inconsistent. Whether your plan covers generic sildenafil depends entirely on the specific policy. Some plans cover it with a copay, others exclude it entirely, and some require prior authorization. The good news is that even without insurance, the out-of-pocket cost for generic sildenafil is low enough that most people pay less than they would with a typical prescription copay.
How to Get Generic Sildenafil
Generic sildenafil requires a prescription. You can get one through an in-person visit with your doctor or through a telehealth service. Many online platforms now offer consultations specifically for erectile dysfunction, often bundling the prescription and medication delivery together. Traditional brick-and-mortar pharmacies, mail-order pharmacies, and online pharmacies all carry it.
When filling your prescription, it’s worth comparing prices across pharmacies. Costs can vary significantly even within the same city. Pharmacy discount cards and coupon websites often offer the lowest prices, sometimes beating insurance copays. Since so many manufacturers produce the drug, supply is rarely an issue.
