Yes, generic Viagra is widely available in the United States. The active ingredient is sildenafil citrate, and it comes in the same 25 mg, 50 mg, and 100 mg tablets as the brand-name version. Teva Pharmaceuticals launched the first FDA-approved generic in December 2017, and multiple manufacturers now produce it, which has driven prices down dramatically.
How Generic Sildenafil Became Available
Pfizer’s patent on Viagra for erectile dysfunction wasn’t set to expire until April 2020. However, Pfizer settled a patent dispute with Teva Pharmaceuticals, allowing Teva to bring a generic to market on December 11, 2017, more than two years early. Since then, several other manufacturers have entered the market, creating competition that benefits consumers.
Same Drug, Different Appearance
Generic sildenafil contains the exact same active ingredient as brand-name Viagra. The FDA requires generics to meet strict bioequivalence standards, meaning the drug must be absorbed into your bloodstream at essentially the same rate and concentration as the original. There is no meaningful clinical difference between the two.
The one obvious difference is how the pills look. Brand-name Viagra is the familiar blue diamond-shaped tablet. Generic versions are typically white to off-white oval tablets with manufacturer-specific markings. Trademark law prevents generic manufacturers from copying the appearance of the brand-name pill, but the medication inside works identically.
How It Works and How Long It Lasts
Generic sildenafil takes effect about 30 to 60 minutes after you take it. Most people experience its effects for two to three hours, though depending on the dose and individual factors, it can remain active for up to five hours or longer. The usual starting dose is 50 mg, taken as needed. Your prescriber can adjust that up to 100 mg or down to 25 mg based on how well it works and whether you experience side effects. You should not take it more than once a day.
One thing worth knowing: sildenafil is also prescribed in a 20 mg dose under the brand name Revatio for a completely different condition, pulmonary arterial hypertension. That version is taken three times daily. If you see sildenafil in 10 mg or 20 mg tablets, it’s the pulmonary hypertension formulation, not the erectile dysfunction version.
Price Difference: Generic vs. Brand
The cost gap between brand-name Viagra and generic sildenafil is enormous. Brand-name Viagra runs roughly $67 to $90 per pill at retail pharmacies, putting a 30-day supply well above $2,000. Generic sildenafil, by contrast, has plummeted in price since its launch. Between December 2017 and mid-2021, the list price for six tablets of 100 mg generic sildenafil fell by 98%, from $265 down to about $4, according to a GoodRx analysis.
At current retail pricing, 30 tablets of generic sildenafil at a 25 mg dose typically cost around $15 to $25 when you use a pharmacy discount coupon. Without any coupon or insurance, the sticker price can be significantly higher (sometimes over $460 for 30 tablets), so it’s worth checking discount programs before filling your prescription.
Insurance and Medicare Coverage
Most insurance plans treat erectile dysfunction medication as non-essential, which limits coverage. Original Medicare (Parts A, B, and D) does not typically cover Viagra or generic sildenafil for ED. Some Medicare Advantage plans may help cover generic versions, so it’s worth checking your specific plan. Medicaid hasn’t covered erectile dysfunction drugs since 2005.
Private insurance varies. Some employer-sponsored plans cover a limited number of pills per month, while others exclude ED medications entirely. The good news is that generic sildenafil has become inexpensive enough that paying out of pocket with a discount coupon is manageable for most people, often costing less than a copay would for other medications.
You Still Need a Prescription
Generic sildenafil is not available over the counter in the United States. You need a prescription from a licensed healthcare provider. This applies whether you fill it at a brick-and-mortar pharmacy or through an online telehealth service. Several telehealth platforms now offer consultations specifically for ED, which has made the process more convenient and private than it used to be.
The prescription requirement exists because sildenafil can interact dangerously with certain medications, particularly nitrates used for chest pain. It can also cause a significant drop in blood pressure. A provider needs to review your health history and current medications before prescribing it. In the United Kingdom, low-dose sildenafil has been approved for over-the-counter sale, but that change has not happened in the U.S.
