I also sometimes use a drug interactions checker.
I get much more info from my pharmacist than I do reading on drugs or using an interaction checker.
She is aware of additional med issues from her own ongoing education and from databases updated daily.
She will call the drug manufacturer if she cannot answer a question.
She also knows if she has had other clients complain of the same issue, even though it's not in the online data.
I usually read all about the med in a "professional" version of info. and/or use a drug reaction checker AND talk with my pharmacist.
My findings: my pharmacist is worth her weight in gold.
