How should epinephrine be stored before use?

Epinephrine should be stored at room temperature to maintain its effectiveness and safety for administration. Storing it at room temperature prevents the potential for temperature variations that could degrade the medication, ensuring it remains potent when needed.

Refrigeration can lead to precipitation or changes in the formulation of epinephrine, which might affect its strength and efficacy. Freezing is also detrimental, as it can cause the solution to become unstable and render it ineffective for use when it is needed in emergency situations. Furthermore, storing epinephrine in direct sunlight can result in degradation of the compound, reducing its effectiveness.

Thus, keeping epinephrine at room temperature, away from light and moisture, is the best practice to ensure its reliability for use in emergencies.
