Answer #6 - That’s where the diary comes in and also when a patient goes to a Dr.'s office and patients are asked for medications that they are taking. It is a very common problem for patients not to include over-the-counter medications on that list. It is extremely important for patients to tell them that they are taking Tylenol or Advil and exactly how much they are taking and if they are forced to document that in a diary. It is even better to do it that way.
