Zepbound has changed lives for many tackling weight loss. This tirzepatide injection curbs hunger and boosts results with healthy habits. But supply issues have frustrated users since its launch.
Backorders mean delays at pharmacies, even when overall stock improves. In 2025, the picture looks better, but local spots still face hiccups. Patients often wait days or weeks for their dose.
This guide dives into the latest on how long is Zepbound on backorder. You’ll learn the history, current status, and steps to get your supply smoothly.
The Roots of Zepbound’s Supply Challenges
Zepbound hit the market in late 2023 amid huge buzz for GLP-1 drugs. Demand soared as stories of 20% weight loss spread. Eli Lilly, the maker, couldn’t keep up right away.
Shortages kicked off in early 2024, with the FDA listing tirzepatide as in short supply by April. Pens for doses like 5 mg and 10 mg vanished from shelves. This forced many to hunt or switch meds.
The issue stemmed from production limits. Making injectable pens takes time, and raw materials ran low. By mid-2024, backorders stretched weeks, hitting patients hard.
Timeline of Shortages and Improvements
The FDA flagged the tirzepatide shortage in December 2022, before Zepbound’s full rollout. It worsened in 2023 with 130,000 weekly prescriptions. By spring 2024, some doses faced months-long waits.
August 2024 brought good news—all doses showed as available on FDA lists. Eli Lilly ramped up factories, adding billions in investments. But pharmacies reported “choppy” stock into fall.
December 19, 2024, marked the official end. The FDA declared no shortage, ending allowances for compounded versions. This cleared the way for steady supply in 2025.
Current Backorder Status in September 2025
As of September 22, 2025, Zepbound is not on national backorder. Eli Lilly confirms all doses—2.5 mg to 15 mg—are shipping without limits. The FDA’s database lists full availability.
Local pharmacies might still delay fills by 2 to 10 days due to distribution lags. High-demand areas like urban centers see more spot shortages. But overall, waits are short now.
Vials for lower doses, launched in 2025, help ease pen bottlenecks. Users report easier access than last year. Check Lilly’s supply site for real-time updates.
Why Backorders Linger Despite No Shortage
Even without a formal shortage, demand outpaces some supply chains. Pharmacies order in batches, and popular doses like 7.5 mg go fast. Weather or logistics can add delays.
Insurance hurdles slow things too. Approvals take time, pushing backorders. Compounded alternatives faded post-2024, funneling more to brand-name Zepbound.
Eli Lilly warns of occasional “empty-handed” visits. But new plants in North Carolina, opened late 2024, boost output by millions of doses monthly.
Dose-Specific Backorder Insights
Not all strengths face equal pressure. Starter 2.5 mg and 5 mg vials stay stocked best, thanks to the new format. Higher 12.5 mg and 15 mg pens see brief holds in busy chains.
In March 2025, a minor wave hit 10 mg at CVS, lasting a week. Most resolved quickly with transfers. Vials cut waits for low doses to under 48 hours.
Track your dose on apps like GoodRx. They flag local stock before you drive.
Regional Differences in Availability
Urban spots like New York or LA face tighter supply from sheer volume. Rural areas might wait longer for deliveries. Chains like Walmart restock faster than independents.
Canada saw similar issues in early 2025, but imports stabilized by summer. Europe reports full stock since spring. U.S. leads in demand, so it fluctuates most.
Call ahead or use drive-thru apps. Some states, like California, have shortage trackers online.
Eli Lilly’s Efforts to Fix Supply
Lilly poured $9 billion into manufacturing in 2024. The Concord facility alone adds 1.6 million doses weekly. They shifted to vials for starters, freeing pen lines.
Partnerships with telehealth like Ro offer direct ships, skipping pharmacy queues. LillyDirect platform shows stock and ships in days. This cut backorders by 70% in 2025.
Future plans include AI-optimized production. By 2026, they aim for zero delays.
What to Do If Your Dose Is Backordered
First, ask your pharmacist to check other locations. Chains transfer easily. Lilly suggests calling 2-10 days early for refills.
Switch to an available dose temporarily, like 5 mg if on 7.5 mg. Your doctor can adjust safely. Avoid gaps—consistency matters for results.
Use Lilly’s portal to order direct. It guarantees stock if prescribed.
Alternatives During Short Delays
If waits drag, consider Mounjaro—same drug for diabetes, often stocked better. Wegovy or Saxenda work similarly but differ in action. Compounded tirzepatide ended in 2025, so stick to approved options.
Your doc might pause and restart later. Diet tweaks bridge short gaps without losing progress.
Here’s a quick list of swaps:
- Mounjaro: Tirzepatide for blood sugar, off-label for weight.
- Wegovy: Semaglutide weekly shot, strong appetite control.
- Oral Rybelsus: Daily pill version of semaglutide.
Weigh pros with your provider.
Impact on Patients and Progress
Backorders stress users out. One missed week can spike hunger, stalling loss. Studies show consistent dosing yields 21% drop over a year.
In 2025, fewer disruptions mean steadier paths. But early-year waits cost some 5-10 pounds regained. Mental toll adds up—plan buffers.
Support groups share tips. Many stock extra when possible.
Comparing Zepbound Shortages to Competitors
Zepbound’s issues mirror Wegovy’s. Novo Nordisk faced years of lows, resolved in August 2024. Ozempic shortages linger for diabetes priority.
Mounjaro, Zepbound’s twin, stocks better due to insurance. All saw 2024 peaks from off-label use.
