Viagra Prices at Costco
This month, Costco’s price for Viagra 100 milligrams is slightly higher than last month at $59.33, which is still much lower than all the other retailers we track. If you only need 50 milligrams, you can use a pill splitter to divide the tablet and halve the cost. That means that 50 milligrams of Viagra at Costco is $29.81.
Viagra pricing at Costco hasn’t changed significantly this year, with no significant changes in price since May 2024.
This is a significant savings compared to other retailers. The current average price for Viagra across major pharmacies is currently $82.41. Other pharmacies can cost upwards of $90 per pill, so if you choose to go to a major pharmacy, Costco is your current low-price leader by far.
Sildenafil Prices at Costco
Generic medications are almost always cheaper than their brand-name alternatives. Sildenafil, which is the active ingredient in brand-name Viagra, is available at a fraction of the price.
At Costco this month, you can expect to pay $1.20 for 100 milligrams of sildenafil, 2 cents more than last month. If you divide the tablet, this works out to be just $0.60 for 50 milligrams. This price has declined twenty cents from January 2025, putting Costco in the middle of the pack this month.
This is a significant savings not only from the brand-name alternative but also compared to other pharmacies. Across all the pharmacies we track, the average cost of 100 milligrams of sildenafil is $5.16.
Costco’s Member Prescription Program
While you need a membership to shop at Costco, the pharmacy at Costco is open to everyone, and charges the same price regardless of whether you have a membership.
However, you may want to join Costco to receive its pharmacy discount, the Costco Member Prescription Program. Available to members, this lets you find discounts on medication on closer pharmacies when you can’t get to Costco.
Currently, a Gold Star membership is $65 per year.
What To Know About Viagra
Viagra (sildenafil citrate) was the first oral treatment for erectile dysfunction, approved by the FDA in 1998. Since its introduction, the “little blue pill” has proven safe and effective for most men.
How Does Viagra Work?
Viagra belongs to the class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. These drugs work by relaxing blood vessels and improving blood flow throughout the body—including the penis.
Contrary to popular belief, Viagra doesn’t cause erections. Instead, PDE5 inhibitors make it easier to achieve and maintain a strong erection when a man is sexually stimulated.
What Is Sildenafil?
Sildenafil is the generic form of Viagra. It has the exact same active ingredient, but at a lower cost. Generic medications are less expensive because there’s no need for marketing or brand-specific packaging. Both Viagra and sildenafil are effective ED treatments, and many men find that sildenafil works just as well as Viagra.
Viagra Side Effects
Viagra and sildenafil are FDA-approved for adult men with erectile dysfunction. It’s not approved for women, people under age 18, or anyone who does not have erectile dysfunction.
As with any medication, Viagra may produce side effects, and understanding these can help users manage them better. The most common side effects of PDE5 inhibitors like Viagra and sildenafil include:
- Headaches
- Nasal congestion
- Facial flushing
- Upset stomach
Less commonly, men may experience changes in vision, like temporary blurriness or seeing a slightly blue tint. This happens because sildenafil, the active ingredient, can affect the PDE6 enzyme in the eyes, although the effect usually resolves as the medication wears off.
Viagra can also cause a drop in blood pressure, so be sure to discuss any heart or blood pressure issues with your doctor.
In some cases, it is possible to experience an erection lasting more than four hours, called priapism. This high-profile side effect is extremely rare, but when left untreated, priapism can cause permanent erectile tissue damage.

Viagra Drug Interactions
Viagra can also interact with other medications, especially those that treat liver, kidney, or heart conditions. Make sure to talk to your doctor about all the prescriptions, over-the-counter drugs, and supplements you’re taking, especially if you’re using nitrates like nitroglycerin.
Alpha-blockers or antihypertensives can also interact with Viagra, leading to a sudden and dangerous drop in blood pressure.
Viagra Alternatives
Viagra and sildenafil work well for many men, but they’re not the only solutions available. If you’re dealing with side effects, health concerns, or simply looking for other options, several alternatives can fit your needs.
Here’s a quick breakdown of other FDA-approved medications for erectile dysfunction.
- Cialis. Cialis stands out for its long-lasting effect—up to 36 hours. It offers more flexibility, making it easier to engage in spontaneous moments. There’s also a daily-use version available in lower doses, so you can be ready for intimacy anytime.
- Tadalafil. Tadalafil is the generic form of Cialis, offering the same benefits but at a lower price. It’s a popular choice for men who want reliable results without the higher brand-name cost.
- Vardenafil. Vardenafil is the generic version of Levitra, which is no longer available as a brand-name medication. It’s a fast-acting option that can start working within 15 minutes, so vardenafil is a great choice if you want a faster onset than Viagra.
- Stendra. Stendra is a newer drug with a similar onset time as vardenafil, kicking in within 15 to 30 minutes, but it often lasts longer—up to six hours. For many men, it causes fewer side effects than Viagra, which makes it a solid alternative for men who may not tolerate Viagra or sildenafil well.
4 Reasons To Buy Viagra Online at eDrugstore
Whichever medication you choose, buying it online isn’t always the cheapest option, many men find that the benefits outweigh the sometimes-negligible cost savings.
Here are four reasons many men prefer to buy their ED medications online.
- Privacy. At least 30 million men in America struggle with erectile dysfunction, so there’s no reason to be embarrassed about talking to your doctor about Viagra. But many men feel more comfortable with the privacy that telemedicine offers. If you’d prefer to avoid an awkward in-person conversation (or being overheard at the pharmacy counter) you can order your prescription by phone and have it shipped straight to your door in discreet packaging.
- Convenience. With eDrugstore, there’s no waiting in line, battling Costco crowds, or finding time in your busy day to make a trip to the pharmacy. For some older people or others with mobility concerns, this convenience can be a lifesaver.
- Free medical consultation. Save the cost of a visit to your doctor by taking advantage of a free consultation with one of our U.S.-licensed physicians. They will help you choose the medication that’s best for you, then write your prescription.
- Discounts. Costco’s pricing may be steady this year, but the overall prices of Viagra and sildenafil have been on the rise. You can try your luck with sales and loyalty cards with in-person pharmacies, but eDrugstore frequently offers discounts on Viagra and other erectile dysfunction medications at 50% or even 75% off retail prices.
- Free shipping. When you order from eDrugstore, shipping is always free.
