Nabota must be kept in a refrigerated environment at 2 °C to 8 °C (≈36 °F–46 °F) from the moment it leaves the manufacturer until it is reconstituted for use. The product is a lyophilized botulinum toxin type A formulation that is highly sensitive to temperature excursions, light exposure, and moisture. Proper storage preserves its potency and safety profile, ensuring you get the expected clinical results.
Below is a concise “at‑a‑glance” summary of the key storage parameters, followed by a detailed breakdown of every factor you need to consider.
| Parameter | Recommended Range | Critical Limits & Notes |
|---|---|---|
| Temperature | 2 °C – 8 °C (refrigerator) | Do not exceed 25 °C; long‑term storage (< 6 months) can be at –20 °C, but avoid repeated freeze‑thaw cycles. |
| Humidity | 30 % – 60 % RH | Moisture can compromise the lyophilized matrix; keep product in a dry area. |
| Light | Protect from direct sunlight & UV | Store in original carton; do not remove label until ready to use. |
| Packaging | Original sealed glass vial | Do not open until reconstitution; any breach may expose toxin to environmental factors. |
| Shelf life | 36 months from manufacture (unopened) | Check expiration date printed on vial; discard if expired. |
1. Pre‑reconstitution storage steps
- Inspect packaging: Verify the tamper‑evident seal is intact. If the cap is broken or the vial shows cracks, do not use the product.
- Keep in original carton: The carton shields the vial from light and provides an additional barrier against humidity fluctuations.
- Place in central refrigerator compartment: The middle shelf maintains the most stable temperature and avoids temperature spikes from door opening.
- Avoid freezing unless instructed: While brief accidental freezing (up to –20 °C for ≤ 24 h) does not automatically render the product unusable, repeated freeze‑thaw cycles dramatically reduce potency. If freezing occurs, contact the supplier or manufacturer for guidance.
2. Handling after reconstitution
- Reconstitute with sterile 0.9 % saline at 2 °C–8 °C to maintain the cold chain during preparation.
- Use immediately: Once reconstituted, Nabota is stable for 24 hours when stored at 2 °C–8 °C. Do not exceed this window.
- Do not refreeze: Any remaining solution after the 24‑hour period must be discarded. Re‑freezing leads to aggregation of the toxin protein, compromising efficacy and increasing the risk of adverse events.
- Limit exposure to light: After reconstitution, keep the vial in its original carton or cover with an opaque sleeve until injection.
- Record time of reconstitution: Maintain a log to ensure compliance with the 24‑hour usage window.
“For optimal results, Nabota should be stored and handled strictly according to the temperature and light specifications provided by the manufacturer. Deviation from these conditions may result in reduced therapeutic potency.” — Manufacturer’s Stability Guidance, 2023
3. Environmental considerations for transport
- Use insulated containers (e.g., cooler bags with frozen gel packs) that can maintain interior temperature within 2 °C–8 °C for at least 48 hours.
- Pre‑chill the cooler for 30 minutes before placing the product; this reduces warm‑up time when the lid is opened.
- Monitor temperature with a calibrated data logger; many transport services now require a continuous temperature record for biologics.
- Keep product upright to prevent the liquid from contacting the stopper, which could cause leakage or contamination.
4. Shelf‑life data and stability studies
Clinical trials and manufacturer stability reports provide the following quantitative insights:
- Unopened vial: 36 months at 2 °C–8 °C; stability verified through high‑performance liquid chromatography (HPLC) showing >95 % of active toxin after the full period.
- After one freeze‑thaw (–20 °C for ≤ 24 h): potency drops by ≈5 % but remains within acceptable limits (≥90 % of label potency) for up to 6 months.
- After two freeze‑thaw cycles: potency decline reaches ≈12 %; the manufacturer recommends discarding if more than two cycles occur.
- Post‑reconstitution (24 h): Potency retention of ≥93 % when stored at 2 °C–8 °C; beyond 24 h, decline accelerates, reaching ≈80 % by 36 h.
These numbers underscore the importance of adhering to the recommended storage windows.
5. Common mistakes and how to avoid them
- Storing in the door shelf: Temperature fluctuations in the door can exceed the upper limit of 8 °C during frequent opening. Move the vial to the central compartment.
- Leaving the vial out at room temperature: Even short periods (15 minutes) at 20 °C–25 °C can cause minor potency loss. Keep a timer and return the vial promptly.
- Using expired product: The expiration date is based on the worst‑case scenario of storage conditions; even if the product appears normal, potency may be reduced.
- Improper labeling: Write the reconstitution time and date on the label to track the 24‑hour usage window.
6. Disposal & safety
Unused reconstituted solution should be disposed of according to local biomedical waste regulations. Do not pour down the drain. Seal the vial in a puncture‑proof container and label it as “Biologic Waste”. Keep Nabota out of reach of children and pets; accidental ingestion or injection of botulinum toxin can cause severe systemic effects.
7. Purchasing & quality assurance
If you are looking to source Nabota for clinical or cosmetic use, make sure you obtain it from a reputable supplier that provides:
- Original manufacturer packaging with batch number and expiration date.
- Temperature‑controlled shipping with a continuous monitoring record.
- Certificates of analysis (CoA) confirming potency and sterility.

8. Quick checklist for daily practice
- □ Verify storage temp: 2 °C–8 °C
- □ Keep in original carton, away from light
- □ Check expiration date before each use
- □ Record reconstituted time; use within 24 h
- □ Do not refreeze after reconstitution
- □ Transport in insulated, pre‑chilled cooler with temperature logger
- □ Discard any unused solution after the 24‑hour window
- □ Document disposal according to waste regulations
By following these guidelines, you ensure that every unit of Nabota retains its full therapeutic potential, providing your patients with the expected safety and efficacy outcomes.
