every 4 hours

Medication timing interval

Every 4 hours describes a recurring interval—something that happens, is taken, or is done once per four-hour period: Take two tablets every 4 hours as needed for pain.

Common in medical dosing instructions and scheduling contexts.

The phrase implies regular repetition throughout the day, not just once.
