Key takeaways:

  • There are many erectile dysfunction (ED) treatments to choose from. Oral pills, such as Viagra (sildenafil) and Cialis (tadalafil), are go-to medications, but several penile injections and medical devices are available too.

  • To find a discount ED medication, consider using a GoodRx coupon, a manufacturer copay card, or a patient assistance program. A healthcare professional can recommend a product that’s safe and effective for you and your symptoms.

  • A 1-month supply of generic Viagra may cost as little as $12.30 with a free GoodRx coupon. Injections such as Caverject may cost as low as $842.85. For products such as Eroxon gel, vacuum erection devices, and constriction rings, it may pay to shop around.

Save on related medications

Erectile dysfunction (ED) medications can make a real difference for your confidence — and your relationship. But high prices can sometimes stand in the way of the treatment you need. Whether you’re considering a popular tablet like Viagra (sildenafil) or doing research on alternatives like Caverject (alprostadil) and Eroxon gel, cost shouldn’t be a barrier to better erections.

The good news is there are ways to save — without cutting corners on safety or effectiveness. Here, we’ll break down how to save on ED medications and medical devices.

Ways to save on ED medications

Health insurance is the preferred way to save on ED medications. But many insurance plans exclude or place restrictions on ED products. There’s also a chance your copay or coinsurance may be too high — or you might not have insurance at all.

There are other ways to save in cases like these, such as:

Most ED medications come as easy-to-take oral tablets. Others are injected directly into the penis. Some are commercially made, while others are mixed by a compounding pharmacy. Several medical devices treat ED too.

Oral ED medications

Viagra is the most well-known ED pill. It’s a type of phosphodiesterase 5 (PDE5) inhibitor. But it’s not the only one; a few other PDE5 inhibitors are also available. They’re all similarly safe and effective.

The main differences between PDE5 inhibitors are related to how long they last and if you should take them with food. Out-of-pocket costs and savings opportunities can also vary. Here’s a summary.

  • Drugs for men: ED isn’t the only health issue that men face. These medications can also support men’s health as part of a broader treatment plan.

Injectable ED medications

Not all ED treatments come in pill form. For those who can’t take oral medications or don’t find them effective, injectable ED medications can be a beneficial alternative. They work directly in the penis to improve blood flow and help you get and maintain an erection.

These medications are generally effective for a wide range of people with ED — including those with health conditions that affect blood flow or nerve function. But they do require a bit more planning and comfort with self-injection. Securing insurance coverage on these products can also be tricky.

Medication

Typical dosage

How to save

Edex (alprostadil) — comes in a syringe

Inject into the base of the penis, up to 3 times per week

As low as $231.94 for Edex with GoodRx

As low as $15 for Edex with a manufacturer savings card

Caverject (alprostadil) — comes in a single-dose vial

Inject into the base of the penis, up to 3 times per week

As low as $842.85 for Caverject with GoodRx

Caverject Impulse (alprostadil) — comes in a syringe

Inject into the base of the penis, up to 3 times per week

As low as $220.51 for Caverject with GoodRx

BiMix (papaverine,  phentolamine) — typically comes in a multidose vial

Inject into the base of the penis, up to 2-3 times per week

Work with your prescriber to find an accredited compounded pharmacy that offers BiMix injections at the best price — prices vary by pharmacy and location

TriMix (papaverine, phentolamine, alprostadil) — typically comes in a multidose vial

Inject into the base of the penis, up to 2-3 times per week

Work with your prescriber to find an accredited compounded pharmacy that offers TriMix injections at the best price — prices vary by pharmacy and location

QuadMix (papaverine, phentolamine, alprostadil, atropine) — typically comes in a multidose vial

Inject into the base of the penis, up to 2-3 times per week

Work with your prescriber to find an accredited compounded pharmacy that offers QuadMix injections at the best price — prices vary by pharmacy and location

Keep in mind that low cost doesn’t always mean best value. It’s important to make sure you’re going to a safe, legitimate pharmacy — especially if you’re using a compounded medication. Look for pharmacies that are accredited by the Pharmacy Compounding Accreditation Board.

Also, be wary of websites that offer prescription drugs without a prescription or sell medications at unusually low prices. These could be signs of an illegal or unsafe operation, and the medications they provide may be counterfeit or contaminated.

Good to know: Muse was another version of alprostadil. It used to be available as a suppository that’s placed in the opening of the penis. Its manufacturer discontinued it in June 2024.

Topical ED products

Eroxon gel is the main example of a reputable, topical ED product. But technically, it’s not a medication. It’s a medical device that contains glyceryl trinitrate. Some people find that it promotes an erection within 10 to 15 minutes of application.

Eroxon is available over the counter (OTC) at most major pharmacies and online. The best way to save is by shopping around. Eroxon’s prices can vary slightly by retailer, and GoodRx discounts aren’t currently available. You can also request a coupon through the manufacturer’s website.

Medical devices for ED

ED medications don’t work for everyone — and that’s OK. Several medical devices can help you achieve or maintain an erection. These devices can be especially helpful for people with certain health conditions, such as Type 2 diabetes or after prostate surgery.

Many of these devices are available OTC. But they vary widely in terms of cost, insurance coverage, and how comfortable they are to use. Here’s a rundown of the most common options, along with examples and tips on how to save.

As with medications, make sure any device you purchase is safe and legitimate. Check its labeling for FDA clearance, especially when shopping online. If you’re unsure which device might work best for you, talk to a healthcare professional.

The bottom line

Erectile dysfunction (ED) treatments don’t have to break the bank. Oral ED pills, such as generic Viagra (sildenafil), cost as little as $12.30 with a free GoodRx coupon. Injectables, such as Caverject (alprostadil) and TriMix (papaverine, phentolamine, alprostadil), are available for people who can’t take pills or don’t benefit from them — though prices vary. Medical devices, such as Eroxon gel, vacuum erection devices, and implants, are additional options to consider. Talk to a healthcare professional about what ED treatments may work best for you.
