Why is it so hard to find Mounjaro in stock?

There are several reasons that Mounjaro is difficult to find. We'll try to keep this overview brief but informative.

Unprecedented demand

Mounjaro has experienced some of the highest demand of any medication in recent history. Originally approved by the FDA in 2022 for type 2 diabetes, Mounjaro quickly gained widespread attention for its significant weight loss effects. The combination of diabetes patients, off-label weight loss prescriptions, and growing public awareness has created demand that far exceeds what Eli Lilly, the manufacturer, can produce.

Manufacturing complexity

Unlike a simple pill, Mounjaro is a biologic injectable medication that requires highly specialized manufacturing facilities. Producing injectable pens at the scale needed to meet current demand requires enormous investment in manufacturing infrastructure. Eli Lilly has invested billions in expanding production capacity, but scaling up biologic manufacturing takes years, not months.

Supply chain constraints

Even when Mounjaro is being manufactured, the supply chain from factory to pharmacy is complex. The medication requires cold chain storage and careful handling throughout distribution. Each dose strength requires its own production run, and pharmacies may receive limited allocations from their wholesalers, meaning they can only order a certain amount each month regardless of patient demand.

Pharmacy economics

When you pick up a medication that is covered by your insurance, your pharmacy sends out a claim to your insurance company, and your insurance company pays the pharmacy a pre-negotiated rate for that medication that is specific to your health plan.

For high-cost specialty medications like Mounjaro, the economics can be complicated. Pharmacies need to invest significant capital to keep these medications in stock, and reimbursement timelines from insurance companies can be slow. Some pharmacies may limit how much Mounjaro they keep on hand simply because of the financial risk involved in stocking an expensive medication that requires refrigeration.

Insurance and prior authorization delays

Many insurance plans require prior authorization before covering Mounjaro, which can create additional delays. Even when a pharmacy has the medication in stock, patients may face weeks of back-and-forth between their doctor and insurance company before the prescription can actually be filled.

Final thoughts

We know navigating pharmacies is complicated, and we're here to be your guide! Simply put, these are the on-going reasons Mounjaro is hard to find:

  1. Unprecedented demand driven by both diabetes treatment and weight management.
  2. Complex biologic manufacturing that takes years to scale up.
  3. Supply chain constraints and limited pharmacy allocations from wholesalers.
  4. Pharmacy economics and the high cost of stocking specialty injectable medications.
  5. Insurance hurdles including prior authorizations and coverage restrictions.
