What does 'tid' mean in medical terms?

  1. Two times a day

  2. Three times daily

  3. Three times a day

  4. Total integrated dose

The correct answer is: Three times a day

In medical terms, 'tid' stands for 'ter in die', which is latin for 'three times a day'. This indicates the frequency with which a specific medication should be taken. Option A and B are incorrect because they refer to 'bis in die' (twice a day) and 'ter in die' (three times a day), respectively. Option D is incorrect because it refers to a completely different medical term and concept.
