Purethal should be refrigerated (2–8°C) in the original packaging to ensure the stability of the preparation. Transferring it to a ziploc bag may expose it to light or moisture, which can affect its effectiveness.

Alternatively, the original Purethal packaging can be placed in a ziplock bag. The pouch can further protect the medication from moisture and accidental damage.
