Storage Guide

Storage depends on the exact molecule, dosage form, container, preservative and manufacturer. Use the current label or stability documentation for that product; do not transfer instructions between products.
What to record
A usable storage record includes unopened temperature, in-use temperature, light protection, freezing restrictions, excursion limits, discard window and the source version.
- Keep temperature excursions documented.
- Do not use a product that was frozen when its label says not to freeze.
- Inspect for label-described changes in color, clarity, particles or container damage.
- Use the shortest applicable discard limit when requirements conflict.
Travel
Plan around the product's labeled excursion range. Avoid direct contact with ice unless the label explicitly permits freezing, and retain identifying packaging and instructions.
