How to Find Caverject in Stock Near You (Tools + Tips)

Caverject (alprostadil injection) isn't sold at every pharmacy, and since Pfizer discontinued the brand in 2025, availability has been inconsistent as the market transitions to generic alprostadil. Whether you've been on this medication for years or just received your first prescription, here's how to find it near you without making dozens of frustrating calls.

Why Is Alprostadil Injection Hard to Find at Pharmacies?

Alprostadil injection is a specialty medication with relatively low dispensing volume compared to oral ED drugs. Most large retail pharmacy chains — CVS, Walgreens, Rite Aid — don't routinely stock it at every location. After Pfizer discontinued the Caverject brand in July 2025, pharmacies that had been ordering the brand were left to source new generic versions from other suppliers, causing additional gaps in local availability.

Step 1: Ask About Generic Alprostadil, Not Just Caverject

Many pharmacies that no longer carry the Caverject brand may stock generic alprostadil injection. These products contain the same active ingredient at the same strength. When calling or visiting a pharmacy, ask specifically: "Do you have generic alprostadil injection in [your dose] micrograms?" This simple wording change can open up many more options.

Step 2: Try Specialty and Compounding Pharmacies

Specialty pharmacies and compounding pharmacies are your best bet for alprostadil injection. Here's why:

Specialty pharmacies focus on medications used in urology, oncology, and other specialties. They are more likely to carry injectable ED medications as part of their core formulary.

Compounding pharmacies can prepare Trimix (alprostadil + papaverine + phentolamine), a compounded alternative that many urologists prefer and that is often more readily available than commercial alprostadil.

Ask your urologist for a referral to a compounding pharmacy they trust, as quality and potency can vary between compounders.

Step 3: Use medfinder to Search Without Calling

Rather than calling pharmacies one by one, medfinder does the work for you. You enter your medication name, dosage, and location — medfinder then contacts pharmacies in your area to find out which ones can fill your prescription. Results are texted to you directly, saving you significant time and hassle.

medfinder covers all medications, including Caverject, generic alprostadil injection, and related injectable therapies.

Step 4: Consider Mail-Order Pharmacies

Many insurance plans offer mail-order pharmacy services, often at a lower copay for 90-day supplies. If your plan covers alprostadil injection, mail-order can be a reliable way to ensure you have a consistent supply without dealing with local stocking issues. Contact your insurance plan to find out which mail-order pharmacies are in your network.

Step 5: Ask Your Urologist to Check Availability

Many urology practices have pharmacy contacts and can often point you to a local specialty pharmacy that has the medication in stock. If you're seeing a urologist for ED treatment, don't hesitate to mention that you're having trouble filling your prescription — their office may be able to recommend a specific pharmacy or compounding partner they work with regularly.

What About Edex — the Other Brand?

Edex is another brand of alprostadil injection made by Endo Inc. It contains the same active ingredient as Caverject and is FDA-approved for the same indication. If Caverject and generic alprostadil are not available at your pharmacy, ask your prescriber if Edex is an appropriate alternative. Your prescription may need to be rewritten, but the medication is clinically equivalent.

Tips for Your Next Pharmacy Call

Ask for "alprostadil injection" by generic name, specifying your dose in micrograms.

Call mid-week, mid-morning for faster pharmacy responses.

Ask if the pharmacy can order it — even if not in stock today, many can get it within a day or two.

Look beyond large chains — independent and specialty pharmacies are often better sources.
