Does It Matter What Time You Take Your Medicine?

The timing of when we take medications could matter in ways that go beyond managing side effects, according to Garret FitzGerald, MD, FRS, a professor of Systems Pharmacology and Translational Therapeutics. “In the last 30 or 40 years, we’ve known that the time of dosing can influence substantially the drug exposure, the drug levels that were attained in blood after giving a drug at different times of day. And yet that’s influenced practice almost not at all,” he said.
