Keflex (cephalexin) capsules can be opened and sprinkled onto food for easy administration if you are having problems swallowing the capsules intact. It is not recommended however, to mix the contents of the capsule with a large volume of liquid.

Mixing the contents of Keflex (cephalexin) with liquid has several disadvantages including:

  • Unpalatable taste
  • Insolubility of the medication
  • Inconsistent dosing

Not only will mixing Keflex (cephalexin) in liquid make it difficult to take based on taste alone, the powder is not soluble, meaning much of it will aggregate at the bottom of the liquid mixture, potentially resulting in you not consuming the entire dose.

Instead, it is recommended to open the capsules and sprinkle the contents on a small amount of food such as applesauce and immediately consume. Alternatively, you can empty the capsules in small amount of viscous liquid like chocolate syrup or honey.

Lastly, when removing the powder from the Keflex (cephalexin) capsules, it is important to try and not break the capsule, but instead open it by removing one half of the capsule (top or bottom). Physically breaking the capsule can result in sharp fragments which are potentially irritating if consumed.
