Normally for prescription stated 3 times a day after meal. does that means 4 hourly or 8 hourly for the interval?

Ask Prescriber: Generally, 3 times a day means an 8 hour interval. However, if the medication is known to irritate the stomach, you may be told to take it 3 times a day with a meal meaning that you take it when you eat. Without knowing the medication, it is hard to advise you. You need to call the provider that prescribed the medication to get clarification.
