Neurotoxin Storage Requirements
Temperature, shelf life, and handling rules for every FDA-approved neurotoxin — from delivery to disposal.
Most neurotoxins must be refrigerated at 2–8°C (36–46°F) before and after reconstitution. Two exceptions: Daxxify can be stored at room temperature before reconstitution, and Xeomin can remain at room temperature for up to 36 months unopened. All reconstituted neurotoxins must be used within 24 hours — no exceptions. Never freeze reconstituted product. Proper storage prevents potency loss and protects your investment in high-value inventory.
Storage requirements by product
| Product | Manufacturer | Unopened Storage | Room Temp OK? | After Reconstitution | Notes |
|---|---|---|---|---|---|
| Botox | AbbVie/Allergan | Refrigerate 2–8°C | No | 24 hours, refrigerated | Do not freeze reconstituted product |
| Dysport | Galderma | Refrigerate 2–8°C | No | 24 hours, refrigerated | Protect from light |
| Xeomin | Merz | Refrigerate 2–8°C | Yes — up to 36 months | 24 hours, refrigerated | Longest shelf life flexibility |
| Jeuveau | Evolus | Refrigerate 2–8°C | No | 24 hours, refrigerated | Standard cold chain |
| Daxxify | Revance | Room temperature OK | Yes | 24 hours | Peptide stabilizer enables room temp |
| Letybo | Hugel/Evolus | Refrigerate 2–8°C | No | 24 hours, refrigerated | Newest product — standard storage |
Why storage matters for your bottom line
Neurotoxins are among the most expensive products in an aesthetic practice — typically $5–7 per unit at cost, $10–18 per unit at retail. A single 100-unit vial of Botox represents $500–700 in cost and $1,000–1,800 in potential revenue. Improper storage doesn't just risk patient safety — it destroys inventory value.
Temperature excursions — even brief periods outside the recommended range — can reduce product potency. A vial that sat on a counter overnight, a mini-fridge that lost power over a weekend, or a shipment that arrived warm can all result in product that's less effective or unusable.
Expiration mismanagement is the other major storage-related cost. Practices that order too much, don't rotate stock (first-in, first-out), or lose track of expiration dates regularly write off hundreds to thousands of dollars in expired product.
The 24-hour rule: no exceptions
Once any neurotoxin is reconstituted, the clock starts. All six FDA-approved neurotoxins must be used within 24 hours of reconstitution. After that window, unused product must be discarded.
This is why proper labeling matters. Every reconstituted vial should be marked with:
- Product name
- Date and time of reconstitution
- Expiration (24 hours from reconstitution time)
- Injector's initials
Example label: "Botox — Mixed 3/26/26 0830 — Exp 3/27/26 0830 — JM"
Practices that reconstitute at the start of a busy day and don't use all the product face a choice: use it on the next morning's first patient (if within 24 hours) or write it off. This is where inventory tracking systems earn their ROI — by alerting you to reconstituted product approaching its expiration window.
Cold chain: receiving and storing shipments
When neurotoxin shipments arrive, proper handling from the moment of delivery matters.
- Inspect on arrival. Check that cold packs are still cold and the packaging is intact. If the shipment feels warm or has been sitting in the sun, document it and contact the vendor before using.
- Refrigerate immediately. For all products except Daxxify, get them into the refrigerator within minutes of arrival — not hours.
- Verify lot numbers and expiration dates. Log these into your inventory system at the time of receipt, not later.
- Rotate stock. First-in, first-out (FIFO). Place new vials behind existing inventory so older product gets used first.
- Separate products. Keep Botox, Dysport, Xeomin, Jeuveau, Daxxify, and Letybo clearly separated in storage. Color-coded bins or labeled shelves prevent confusion.
- Monitor refrigerator temperature. A thermometer inside your storage fridge — checked daily — catches temperature drift before it damages product. Digital thermometers with alerts are ideal.
Room temperature storage: Daxxify and Xeomin
Two neurotoxins break from the standard cold-chain requirement, which has practical inventory implications:
Daxxify
Daxxify uses a novel peptide stabilizer (instead of human albumin), which allows unopened vials to be stored at room temperature. This simplifies logistics — no cold shipping required, no refrigerator space needed for backup stock. After reconstitution, Daxxify follows the same 24-hour rule as every other product.
Xeomin
Xeomin's "naked" formulation (no complexing proteins) gives it exceptional stability. Unopened vials can be stored at room temperature for up to 36 months — the longest shelf life flexibility of any neurotoxin. This makes Xeomin a practical choice for practices that want to keep backup stock without worrying about refrigerator capacity.
If refrigerator space is limited, consider keeping Daxxify and Xeomin as your room-temperature backup stock. This frees up cold storage for products that require it — Botox, Dysport, Jeuveau, and Letybo.
Expiration management best practices
Expiration-related waste is one of the most preventable sources of inventory loss. These practices minimize write-offs:
- Set alerts at 90, 60, and 30 days before expiration. 90 days gives you time to plan. 30 days creates urgency.
- Review expiring inventory weekly. Make it part of your Monday routine.
- Transfer before it expires. If one location has slow-moving product, transfer it to a busier location where it will get used.
- Order smaller quantities more frequently. Larger orders get better per-unit pricing but increase expiration risk. Find the balance.
- Track expiration write-offs in dollars. "We expired 3 vials" is abstract. "$1,500 in expired product this quarter" gets attention.
