PC: Post Cibum

Typically used in prescriptions or prescribing documents, the abbreviation PC comes from the Latin term Post Cibum, meaning after meals.

Certain medications are absorbed into the bloodstream more effectively when there is food in the stomach and gut. When these medications are prescribed, it is often advised that they are taken Post Cibum - or after meals. 

 

Are cannabis-based medications prescribed to be taken Post Cibum, or after meals?

 

Yes, cannabis-based medications may be prescribed to be taken post cibum (PC), or after meals. Here’s why:

  • Improved absorption: Taking cannabis-based medications after meals can enhance the absorption of cannabinoids. The presence of dietary fats in the stomach can increase the bioavailability of cannabinoids, making them more effective.
  •  
  • Reduced gastrointestinal side effects: Consuming these medications with food can help minimise potential gastrointestinal discomfort, such as nausea or stomach cramps, which can sometimes occur with medical cannabis administration.
  •  
  • Stabilised blood levels: Eating before taking cannabis-based medications can lead to more stable and consistent levels of cannabinoids in the bloodstream, which can be beneficial for managing symptoms effectively.
