How to Check If a Pharmacy Has Caverject in Stock (Without Calling)

Caverject (alprostadil injection) is not stocked at every pharmacy, and with the brand discontinued in 2025, the landscape is more fragmented than ever. Many patients describe the experience of calling pharmacy after pharmacy, waiting on hold, only to be told the medication is out of stock. Here are more efficient ways to check availability — including options that let you skip the calls entirely.

Why Is Checking Caverject Availability So Difficult?

Unlike common medications like metformin or lisinopril, alprostadil injection is a specialty drug with low dispensing volume. Most retail pharmacy chains don't include it in their core formulary or may only stock it at certain locations. Since Pfizer discontinued the Caverject brand in July 2025 and the market transitioned to generic alprostadil, pharmacy stocking patterns have changed and individual pharmacy inventory varies more than it used to.

There is also no national real-time pharmacy inventory database that the public can access — so most standard approaches rely on direct pharmacy contact.

Method 1: Use medfinder (Recommended)

The most efficient approach is to use medfinder. Rather than making individual calls yourself, medfinder contacts pharmacies in your area on your behalf to find out which ones have your medication in stock and can fill your prescription. Here's how it works:

Enter your medication name ("alprostadil injection" or "Caverject"), dose, and zip code

medfinder calls pharmacies near you to check availability

You receive a text with results — which pharmacies can fill your prescription

medfinder covers all medications, including Caverject, generic alprostadil, and other injectable ED medications. It saves patients significant time compared to the DIY approach.

Method 2: GoodRx Pharmacy Locator

GoodRx.com allows you to search for your medication by name and zip code, showing pharmacies that carry it along with coupon pricing. While GoodRx pricing data is real-time, inventory information is not always updated — it shows which pharmacies "can" dispense the drug based on their formulary, not necessarily whether they have it in stock today. However, it's a useful starting point to identify which pharmacy types and chains are most likely to carry alprostadil injection near you.

Method 3: Call Specialty and Compounding Pharmacies Directly

Rather than calling your nearest CVS or Walgreens, target specialty pharmacies and compounding pharmacies that are more likely to stock injectable ED medications. Tips for more effective pharmacy calls:

Ask for generic alprostadil injection, not just Caverject brand (which is discontinued)

Specify your dose in micrograms (e.g., "20 mcg alprostadil injection for intracavernosal use")

Ask if they can order it — even if not in stock today, most pharmacies can order within 1–3 business days

Call mid-week (Tuesday–Thursday) and mid-morning for shorter wait times

Method 4: Ask Your Urologist's Office

Urology practices that frequently prescribe injectable ED therapy often have working relationships with local specialty and compounding pharmacies. Your urologist's office may be able to directly refer you to a pharmacy that has alprostadil in stock — saving you the legwork entirely. Don't hesitate to call the prescribing office and explain that you're having trouble filling your prescription.

Method 5: Mail-Order Pharmacy

If local pharmacy availability is consistently a problem, consider switching to a mail-order pharmacy. Many insurance plans offer mail-order benefits for specialty medications at reduced copays. Mail-order specialty pharmacies maintain more consistent stock of injectable medications than most local retail chains. Contact your insurer to identify covered mail-order pharmacies for alprostadil injection.

What If I Also Need Edex or Trimix?

The same strategies apply. Use medfinder to check for Edex (alprostadil by Endo) availability, or contact compounding pharmacies directly for Trimix. Compounding pharmacies typically prepare Trimix to order and may be more consistently available than commercial injectable products at retail chains.
