The Supply Problem
GLP-1 medication shortages have affected millions of patients since 2022. Explosive demand — driven by the medications' effectiveness for both diabetes and weight loss — has repeatedly outstripped manufacturing capacity. Understanding the current situation and your options helps you avoid treatment interruptions.
Note: Shortage status changes frequently. This guide provides strategies that remain relevant regardless of which specific medications are in shortage at any given time.
Why Shortages Happen
The GLP-1 shortage is driven by a confluence of factors:
- Unprecedented demand: GLP-1 prescriptions grew over 300% between 2020 and 2025
- Manufacturing complexity: GLP-1 agonists are biologics requiring specialized production facilities
- Capacity lag: Building new manufacturing plants takes 3-5 years
- Multiple dose strengths: Each dose level requires separate production runs, and starter doses often run short as new patients begin treatment
- Off-label demand: Significant prescribing for weight loss increased demand beyond what manufacturers projected for diabetes alone
How to Check Current Shortage Status
- FDA Drug Shortage Database: The official source for current shortage information (search for semaglutide or tirzepatide)
- Your pharmacy: Call ahead before assuming your refill is available
- Manufacturer websites: Novo Nordisk and Eli Lilly publish supply updates
- Your doctor's office: They often receive advance notice of supply issues
What to Do During a Shortage
1. Don't Panic-Skip Doses
If your specific dose is unavailable, contact your doctor before skipping. Abruptly stopping GLP-1 therapy can lead to appetite rebound and blood sugar spikes. There are almost always alternatives.
2. Check Multiple Pharmacies
Shortage impact varies by region and pharmacy. If your usual pharmacy is out of stock:
- Call other local pharmacies (including grocery store and warehouse pharmacies)
- Check specialty pharmacies that may have dedicated GLP-1 supply chains
- Consider mail-order pharmacies, which sometimes have broader inventory
- Ask your doctor if they have office samples
3. Ask About Dose Substitutions
If your specific dose strength is unavailable but others are in stock:
- Lower doses: Your doctor may temporarily prescribe a lower dose rather than no dose
- Multiple pens: For some dose strengths, two lower-dose pens can be used (your doctor will advise)
- Different formulation: If Wegovy is short, Ozempic may be available (same molecule, different brand)
4. Consider Switching Medications
If semaglutide is unavailable, tirzepatide may be in stock (or vice versa). Switching between GLP-1 medications is medically straightforward:
- Semaglutide → Tirzepatide: Your doctor will select an appropriate tirzepatide dose based on your current semaglutide dose
- Tirzepatide → Semaglutide: Same process in reverse
- Brief titration: A short dose adjustment period may be recommended when switching
Discuss with your doctor — they can guide the transition to minimize side effects.
5. Compounding Pharmacies
During FDA-declared shortages, compounding pharmacies are permitted to produce semaglutide and tirzepatide preparations. Key considerations:
Potential benefits:
- Often more affordable ($200-$500/month)
- May have supply when brand-name products don't
- Some compounders offer home delivery
Important risks:
- Not FDA-approved — quality and purity are not guaranteed to the same standard
- Potency may vary between batches
- Sterility standards vary between compounding pharmacies
- FDA has taken enforcement action against some compounders as brand supply stabilizes
- When the FDA resolves a shortage, compounders lose their legal basis to produce the drug
If you use a compounding pharmacy:
- Choose a 503B-registered outsourcing facility (higher quality standards than 503A pharmacies)
- Verify the pharmacy with your state board of pharmacy
- Discuss with your doctor before switching to compounded medication
- Monitor for differences in effectiveness or side effects
Planning Ahead
Build a Buffer
If your medication is available, don't wait until the last day to refill:
- Refill as early as your insurance allows (typically when you have 7-10 days of supply remaining)
- Ask your doctor for a 90-day prescription if your plan allows it
- Some mail-order pharmacies offer auto-refill programs
Have a Backup Plan
Discuss with your doctor in advance:
- Which alternative medication you would switch to if your current one becomes unavailable
- What dose adjustments to make if only certain strengths are in stock
- Whether compounding is an acceptable backup option for you
Stay Informed
- Sign up for shortage alerts from your pharmacy
- Follow manufacturer supply updates
- Join patient communities where shortage information is shared in real time
The Manufacturing Response
Both Novo Nordisk and Eli Lilly have invested billions in expanding manufacturing capacity:
- New production facilities in the US, Europe, and Asia
- Expected to significantly increase supply through 2026-2027
- Additional dose forms (higher-dose oral semaglutide) may distribute demand more evenly
Frequently Asked Questions
Will GLP-1 shortages end?
Manufacturing capacity is expanding rapidly. Both manufacturers have made massive investments in new facilities. Supply is expected to improve substantially through 2026-2027, though spot shortages of specific dose strengths may continue to occur.
Can I stockpile my medication?
Insurance typically limits you to a 30 or 90-day supply. Some plans allow early refills. Stockpiling beyond what your insurance covers would require paying cash, which is expensive. A modest buffer (refilling early when allowed) is reasonable.
Is compounded semaglutide safe?
Compounded medications are legal during declared shortages but carry more risk than FDA-approved products. Quality depends heavily on the compounding pharmacy. Choose 503B-registered facilities and discuss with your doctor. When the shortage resolves, compounders may no longer legally produce the medication.
What happens if I miss doses due to a shortage?
Missing a week or two is unlikely to cause lasting harm, but you may experience some appetite return. If you miss more than 4 weeks, your doctor may recommend restarting at a lower dose to minimize side effects when you resume.
Can my doctor give me samples?
Some doctors receive manufacturer samples. Ask — especially during shortages. Samples are typically starter doses, which can bridge a gap while you wait for your pharmacy to restock.
Should I switch to a different GLP-1 to avoid shortages?
If your current medication is frequently unavailable, switching to a more reliably supplied alternative is reasonable. Your doctor can help assess which option is most consistently available in your area.
