What issue is noted in relation to the storage of Cephalexin suspension?

Cephalexin suspension needs to be shaken well before each use to ensure that the medication is evenly distributed. This is important because suspensions contain solid particles that settle at the bottom over time. Shaking the bottle before administration redistributes these particles, providing the correct dosage of the active ingredient in each dose.

Storing Cephalexin in a certain temperature range is crucial, but it does not necessarily require refrigeration, and it should not be stored in a dark place nor mixed with a sweetener for safe use. These factors do not pertain to the need for ensuring proper dosage and effectiveness of the medication. The requirement to shake the suspension ultimately contributes to the medication's efficacy and safety during treatment.
