What does 'pc' indicate regarding the timing of medication?

The abbreviation 'pc' stands for "post cibum," which is Latin for "after meals." This term is commonly used in medical settings to indicate that a medication should be taken after a meal. The timing is important because taking medications with or after food can influence their absorption in the body or mitigate potential gastrointestinal side effects.

The other options provide different timings related to medication administration. "Hour of sleep" refers to medications taken at bedtime, "before meals" indicates medications that should be taken prior to eating, and "as needed" refers to medications that can be taken at the patient's discretion, rather than at scheduled times. Understanding these distinctions is crucial for proper medication management and adherence to prescribed treatment plans.
