How to Save Money on Caverject in 2026: Coupons, Discounts, and Patient Assistance

If you've priced out Caverject at your local pharmacy, you already know: it is expensive. Without insurance, six vials of 40 mcg Caverject can cost over $1,000 at retail price. But there are several strategies that can significantly reduce your out-of-pocket cost — and with the brand now discontinued and generic alprostadil available, the savings opportunities are changing. Here's a complete guide for 2026.

How Much Does Caverject Cost Without Insurance?

The retail price for Caverject varies significantly by strength, quantity, and location:

Caverject 20 mcg (6 vials): ~$654–$800 retail

Caverject 40 mcg (6 vials): ~$860–$1,058 retail

Caverject Impulse (2 syringes): ~$288–$308 retail

At these prices, Caverject is one of the more expensive injectable ED medications. However, several discount strategies can meaningfully reduce your costs.

1. Use GoodRx or SingleCare Discount Cards

Prescription discount cards are available through GoodRx and SingleCare and can be used at the pharmacy even without insurance. In 2026:

GoodRx: Caverject available for as low as ~$884 (17% off the average retail price of ~$1,058 for the most common version). Caverject Impulse available for as low as ~$222 (28% off retail).

SingleCare: Caverject Impulse available for as low as ~$219. Generic alprostadil may also be available for significantly less.

These cards are free to use and can be used instead of — but not in combination with — insurance. If your insurance copay is higher than a discount card price, you can sometimes opt to pay cash with the card instead.

2. Switch to Generic Alprostadil

Now that Pfizer has discontinued the Caverject brand and released generic equivalents, generic alprostadil injection is available and may be significantly less expensive than the brand was. Generic medications often cost 50–80% less than their brand-name equivalents over time as competition increases. Ask your pharmacist for generic alprostadil injection and check its price with a GoodRx coupon — this combination may offer the best pricing available.

3. Ask About Trimix Through a Compounding Pharmacy

Compounded Trimix is often less expensive per dose than brand or generic alprostadil — and for many men, it is more effective at lower doses. The per-injection cost of Trimix through a compounding pharmacy can be substantially lower, especially when factoring in that less volume is needed per dose compared to alprostadil monotherapy. Ask your urologist for a Trimix prescription and get pricing from your local compounding pharmacy.

4. Use Insurance — But Know the Rules

Most major insurance plans — including employer plans, Medicaid (in many states), and some Medicare Part D plans — cover alprostadil injection when prescribed for erectile dysfunction, but typically require:

Prior authorization: Your prescriber must submit documentation confirming your diagnosis and that you've tried or are contraindicated to oral PDE5 inhibitors.

Step therapy: Some plans require documented failure of oral ED medications before approving injectable therapy.

Once approved, your copay could be as low as $0–$30 on some plans. Medicare Part B may cover injectable alprostadil, which is administered differently than oral drugs. Check with your insurer to understand your specific benefit.

5. Patient Assistance Programs

Patient assistance programs (PAPs) provide free or heavily discounted medications to eligible patients who cannot afford them. Options include:

Pfizer's patient assistance: Pfizer historically offered patient assistance for Caverject. With the brand discontinued, contact Pfizer to understand current assistance options for generic alprostadil.

Prescription Hope: A medication access service that provides alprostadil-class medications through PAPs for a $70/month service fee per medication.

NeedyMeds.org: A free database of patient assistance programs for nearly all medications. Search for alprostadil to find current programs.

6. Fill a 90-Day Supply

When ordering through insurance or mail-order pharmacy, a 90-day supply is almost always less expensive per unit than 30-day fills. If you're on a stable dose, ask your prescriber to write a 90-day prescription and confirm your pharmacy or mail-order plan can fill it in that quantity.

Finding the Cheapest Pharmacy Near You

Prices vary significantly from pharmacy to pharmacy, even with the same GoodRx coupon. medfinder can help you locate pharmacies near you that actually have alprostadil injection in stock — because the cheapest coupon price means nothing if the pharmacy doesn't carry the drug.
