What to Do If You Can't Find Your Medication

Immediate Steps

1. Call multiple pharmacies — supply varies by location
2. Check specialty pharmacies — may have better access
3. Use the Eli Lilly locator — search for pharmacies with stock
4. Ask about mail-order options through your insurance

If Your Dose Is Unavailable

• Consult your provider about temporarily adjusting doses
• Don't skip doses without medical guidance
• Don't use someone else's medication
• Don't purchase from unverified online sources

Alternative Options During Shortage

• Ask about other GLP-1 medications as a temporary bridge
• Consider authorized specialty pharmacies

Avoiding Counterfeit Products

The high demand has led to counterfeit tirzepatide products. Protect yourself:

• Only purchase from licensed US pharmacies
• Be wary of prices that seem too good to be true
• Don't buy from social media or unverified websites
• Check for proper FDA labeling and lot numbers
• Report suspected counterfeits to FDA MedWatch
