After mixing, how should a prescription for BenzaClin be stored?

1. Refrigerator

2. Freezer

3. Room temperature

4. Warm and moist environment

The correct answer is: Room temperature

After mixing, a prescription for BenzaClin should be stored at room temperature. This is important because storage conditions significantly affect the stability and efficacy of the medication. BenzaClin, which combines clindamycin and benzoyl peroxide, is typically formulated to remain effective when kept in a cool, dry place, away from extreme temperatures. Storing BenzaClin at room temperature prevents degradation that could occur if left in a refrigerator or freezer, where moisture can condense and affect the formulation. Additionally, a warm and moist environment, such as a bathroom, can cause an adverse reaction or significantly reduce the shelf-life of the product. Thus, keeping it at room temperature maintains its quality and therapeutic effectiveness.
