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

Finding Lubiprostone (Amitiza) in stock at a nearby pharmacy can feel like searching for a needle in a haystack. You call one pharmacy and they're out. You call another and they don't even carry it. Meanwhile, your supply is running low. This guide gives you a practical, step-by-step approach to locating Lubiprostone near you — using the best tools available in 2026.

Why Does Lubiprostone Stock Vary So Much?

Lubiprostone (brand: Amitiza) went generic after its patents expired in 2024–2025. While this was good news for pricing, the transition created new availability challenges: only a handful of manufacturers make generic Lubiprostone, and not every pharmacy stocks it regularly. Large chains tend to order based on local demand, so if your area doesn't have many Lubiprostone prescriptions, your pharmacy might not keep it on hand at all.

Step 1: Use medfinder to Check Pharmacy Availability

The fastest way to find Lubiprostone near you is to use medfinder. medfinder calls pharmacies in your area to check which ones actually have your medication in stock — so you don't have to spend your afternoon on hold. You provide your medication, dose, and location, and medfinder handles the pharmacy calls. Results come back to you by text.

Step 2: Call Independent Pharmacies First

When a chain pharmacy like CVS or Walgreens is out of Lubiprostone, your next best bet is an independent local pharmacy. Independent pharmacies often work with multiple drug wholesalers, giving them access to inventory that chains don't have. They also tend to be more flexible — they can sometimes order from a different distributor and have it within 24–48 hours.

To find independent pharmacies near you, search Google for "independent pharmacy near me" or ask your doctor's office for recommendations. Many independent pharmacists will check their wholesaler's stock before you even drive over.

Step 3: Ask Your Current Pharmacy to Order It

If your usual pharmacy is out but you don't want to switch, ask them to order it. Most pharmacies can place a special order with their wholesaler. This typically takes 1–3 business days. The key is to ask before you completely run out — don't wait until the last pill. Calling a week ahead gives your pharmacy time to source the medication without leaving you without it.

Step 4: Consider Mail-Order Pharmacy

Mail-order pharmacies — including those affiliated with major insurance plans like CVS Caremark and Express Scripts — often have more reliable inventory than retail locations. They also ship 90-day supplies, which reduces how often you need to refill. If your insurance plan has a mail-order option, this can be a game-changer for medications with inconsistent local availability.

Step 5: Ask for a 90-Day Prescription

If you've been getting 30-day prescriptions, ask your doctor to write for 90 days instead. This does two things: it reduces how often you need to go through the search process, and it gives you a larger buffer before you risk running out. Many insurance plans and mail-order pharmacies offer 90-day supplies at a lower per-unit cost as well.

Step 6: Check Whether Brand or Generic Is Available

When you call a pharmacy, ask specifically about both brand Amitiza AND generic Lubiprostone. Sometimes one is in stock when the other isn't. Generic Lubiprostone is therapeutically equivalent to brand Amitiza — same active ingredient, same dose. In most cases, you can switch between them without any clinical difference, though you should confirm with your doctor or pharmacist first.

Step 7: Be Specific About Your Dose

Lubiprostone comes in two doses: 8 mcg and 24 mcg. The 24 mcg dose is used for CIC and OIC; the 8 mcg dose is used for IBS-C. When calling pharmacies, always specify which dose you need. A pharmacy might have 24 mcg in stock but not 8 mcg (or vice versa), so being specific saves time.

What If You Still Can't Find It?

If you've exhausted these options and still can't find Lubiprostone, it's time to talk to your doctor. There are effective alternatives in the same therapeutic space — Linzess (linaclotide), Trulance (plecanatide), and Motegrity (prucalopride) are all options your provider might consider.
