Viagra and Sildenafil Prices at Amazon

Updated for July 2026

* Calculated by cost of 100 mg tablet, cut in half with a pill splitter

Amazon Pharmacy’s pricing for both brand-name Viagra and generic Sildenafil has remained steady since April. Their current strategy places their brand-name pricing slightly above the national average, but their generic pricing is dramatically lower than the competition.

Viagra Prices at Amazon

Amazon lists brand-name Viagra at $58.13 per 100 milligram pill. This price places Amazon well below the current national average of $82.41 for 100 milligram Viagra and just under Costco’s next-lowest price of $59.63.

Many men need only 50 milligrams, so they can divide the larger dose in half with a pill splitter. This brings the cost down to $29.66 per dose.

Understanding Pricing at Amazon Pharmacy

If Amazon’s Viagra pricing sends you into sticker shock, remember to check the quantities before ordering. Amazon Pharmacy defaults to selling six tablets at a time, which explains why it appears as $535.56 in your cart.

Amazon vs. Competitor Pharmacies

Shopping for Viagra online or in pharmacies will reveal a wide range of prices. At the world’s largest pharmacy, Walgreens, 100 milligrams Viagra is significantly more expensive than at Amazon—$93.43 per pill. CVS and Target pharmacies currently list it at $91.81. Costco is close behind Amazon at just $59.33.

Viagra (sildenafil citrate) is a brand name erectile dysfunction medication FDA-approved and created by Pfizer. It was originally developed to treat high blood pressure, but researchers quickly discovered that it was most effective at helping men achieve and maintain better erections during sex. 

Since then, “the little blue pill” has been the go-to ED treatment for millions of men.

How Viagra Works

Viagra belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. The PDE5 enzyme helps regulate blood pressure, and by blocking it, Viagra improves blood flow and relaxes blood vessels. 

This effect doesn’t directly cause an erection, but it does allow more blood to flow to the penis. Erectile dysfunction is more common with age, but it can be related to health conditions, medication, emotional health, lifestyle, and more. 

Viagra Side Effects

Viagra is effective for 70 percent of men, but like all medications, it can cause side effects. The most common side effects of PDE5 inhibitors are headaches, nasal congestion, and facial flushing. All of these are related to changes in blood flow and blood pressure.

Some men may experience temporary changes in vision or a slightly bluish tint to the skin. These changes resolve on their own as the medication wears off.

In rare cases, it’s possible to experience priapism, an erection lasting four or more hours. This is a serious condition that requires medical attention.

Viagra Drug Interactions

Viagra can interact with other medications. If you have a heart condition or high blood pressure, be sure to talk to your doctor before taking Viagra or generic sildenafil. 

Men who take nitrates like nitroglycerin should not take Viagra because it can cause a sudden and dangerous drop in blood pressure.

Viagra vs. Sildenafil: What’s the Difference?

The only real difference between Viagra and sildenafil is branding. Sildenafil is the name of the active ingredient in Viagra and is available as a generic form of the medication. 

Men have trusted brand-name Viagra for over 25 years, so some prefer to stick with a familiar brand name with a long history of success.

Sildenafil is always cheaper than Viagra, so if cost is your primary concern, you may want to consider the generic form. The active ingredient in both is identical, but there may be slight differences in filler ingredients and dyes. 

If you have allergies or sensitivities to certain inert ingredients, discuss your options with your doctor. 

Viagra Not Right for You? We Carry Alternatives!

Viagra may not be right for everyone, but there are alternatives. While all ED medications belong to the same class and work the same way, there are slight differences among them. 

Here’s what to know about the other ED medications available at eDrugstore.

• Cialis. Cialis is a popular alternative to Viagra because it lasts much longer—up to 36 hours at a time. This is a great option for men who want flexibility in timing. At a lower dose, Cialis can even be taken daily.
• Tadalafil. Tadalafil is the generic form of Cialis. It’s available in both an on-demand version (which you take as needed) and a low-dose, daily-use formula that allows men to be ready for intimacy anytime.
• Vardenafil. Vardenafil is a generic medication that was previously available under the brand name Levitra. This ultra fast-acting ED medication kicks in after only 15 minutes, so it’s great for spur-of-the-moment sexual activity.
• Stendra. Like Viagra, Stendra is a PDE5 inhibitor—but this medication lasts longer, kicks in sooner, and may have fewer side effects. Some men find that Stendra is easier on their stomachs than Viagra or sildenafil.
