Have the exact product ready
Have the brand, the strength, the device (pen or injection) and the quantity from your prescription. A pharmacy can carry one strength of Mounjaro and be out of the next, so ask about yours specifically.

Find Mounjaro in stock
Shortage status, strengths and how to find Mounjaro at a pharmacy.
To find Mounjaro in stock, call pharmacies with the exact product on your prescription (Mounjaro, your strength, and the device it comes in) and ask whether it's in stock today and when the next delivery is due. Because Mounjaro comes in step-up strengths, a pharmacy can have one and be out of the next. Once a pharmacy confirms your strength, ask your prescriber to send the prescription there.

Is Mounjaro in shortage?
As of October 14, 2026, the FDA's drug shortage database has no current shortage listing for tirzepatide sold as Mounjaro. That is national manufacturer supply. A pharmacy can still be out of a particular strength on a given day.
FDA's tirzepatide listings name the brand in each package description, so this checks only Mounjaro packages. See FDA's listing.
How to find Mounjaro in stock
Ask whether the problem is stock or coverage
A stock problem and a coverage problem can look the same at the counter, and many plans require prior authorization for these medicines. Ask: "Is the problem that you don't have it, or that the claim was rejected?"
Ask your pharmacy about the next delivery
Ask whether your strength is in stock today, whether it is on order, and when the next delivery is due. A pharmacist may also know which strengths they can usually get.
Name the strength and the device
Mounjaro's strengths step up, and RxNorm lists more than one device for each. Give the pharmacy the strength and device on your prescription so they check the right product, and don't accept a different strength or device without your prescriber's OK.
Call other pharmacies
Check chains, grocery-store pharmacies and independents, and say you need the FDA-approved brand product as prescribed. How to ask a pharmacy if a medication is in stock has a ready-to-read script.
Have your prescriber send it where it's in stock
Once a pharmacy confirms it has your strength, ask your prescriber's office to send the prescription there. Please don't split a dose, combine strengths or stretch a pen to bridge a gap. Call your prescriber, who decides any change to your dose or medicine.
Or let Needle make the calls
Needle phones pharmacies for you, using AI voice agents and human callers, asks for your exact Mounjaro strength and form, and reports which pharmacies said they have it. Its database covers 60,000+ US pharmacies, and pay-as-you-go searches cost $1.00 per pharmacy call (credits roll over). Start a search.
Mounjaro strengths and forms
NIH RxNorm, the National Library of Medicine's standard drug vocabulary, lists Mounjaro in these forms and strengths as of October 14, 2026. A listed strength isn't a promise any pharmacy stocks it, and only your prescriber can change yours.
| Form | Strengths |
|---|---|
| Auto-injector pen |
|
| Pen injector |
|
| Injection |

Single-dose products are shown as total dose and volume (for example, 2.5 mg/0.5 mL). Multi-dose pens are shown by concentration and pen volume, as RxNorm records them; your prescription and pharmacy label give the dose per injection.
What is Mounjaro?
Mounjaro is Eli Lilly's brand of tirzepatide. MedlinePlus lists tirzepatide injection to control blood sugar in certain people with type 2 diabetes; tirzepatide for weight loss and obstructive sleep apnea is sold under a different brand, Zepbound. RxNorm lists Mounjaro in several devices (auto-injector pens, 0.5 mL single-dose injections and multi-dose pens), each in several strengths. RxNorm lists tirzepatide only under the Mounjaro and Zepbound brands, so there is no generic to ask for. FDA declared the tirzepatide shortage resolved on December 19, 2024.

Frequently asked questions
Is Mounjaro in shortage right now?
No. As of October 14, 2026, the FDA's drug shortage database has no current shortage listing for tirzepatide sold as Mounjaro. A pharmacy can still be out of a particular strength on a given day, so ask about yours.
What strengths does Mounjaro come in?
NIH RxNorm lists Mounjaro as auto-injector pens in 2.5 mg/0.5 mL, 5 mg/0.5 mL, 7.5 mg/0.5 mL, 10 mg/0.5 mL, 12.5 mg/0.5 mL and 15 mg/0.5 mL, pen injectors in 4.17 mg/mL × 2.4 mL, 8.33 mg/mL × 2.4 mL, 12.5 mg/mL × 2.4 mL, 16.7 mg/mL × 2.4 mL, 20.8 mg/mL × 2.4 mL and 25 mg/mL × 2.4 mL and injections in 2.5 mg/0.5 mL, 5 mg/0.5 mL, 7.5 mg/0.5 mL, 10 mg/0.5 mL, 12.5 mg/0.5 mL and 15 mg/0.5 mL. Your prescription names your strength and form, and only your prescriber can change them.
Is Mounjaro the same as Zepbound?
Both are tirzepatide from Eli Lilly, but they are separate brands with different approved uses. A pharmacy can't fill a Mounjaro prescription with Zepbound or the other way around; only your prescriber can change your medicine.
Is there a generic Mounjaro?
No. RxNorm lists tirzepatide only under the Mounjaro and Zepbound brands. FDA says compounded drugs are not FDA-approved and are not reviewed for safety, effectiveness or quality before they're marketed, so ask your prescriber and pharmacist before accepting any substitute.
Why can't I find my Mounjaro strength if it isn't in shortage?
A shortage ruling is about national supply. A pharmacy still has to order the exact strength and device from its wholesaler, so a gap in one strength can leave a prescription unfilled for a while. FDA notes that when a drug is out of stock at a pharmacy, it is often a local and temporary problem.
