Ayurvedic Principles

Dosage Frequency: Frequency of Taking Medicine

How often you should take any medicine is called frequency in respect of medication. For example, your doctor may ask you to take medicine once a day or twice a day.

Your doctor may write this in abbreviations:

The doctor should not use abbreviations for advising frequency of taking medicine. The most of health organizations prohibit it for safe medical practice and better understanding for patients.
