Which of the following is NOT associated with liquid oral antibiotics that require refrigeration?

  1. Penicillin VK

  2. Bactrim

  3. Amox/clav

  4. Ampicillin

The correct answer is: Bactrim

Liquid oral antibiotics that require refrigeration are usually suspensions that contain water and therefore are more prone to degradation and bacterial growth at room temperature. Bactrim is not one of the antibiotics that require refrigeration as it is a stable, oral suspension that can be stored at room temperature. Penicillin VK, Amox/clav, and Ampicillin are examples of liquid oral antibiotics that require refrigeration to maintain their stability and efficacy.
