Why are blood levels checked when using medications?
March 23, 2009 12:27AM
In situations where a clear dose-response relationship exists for the drug in question, monitoring drug serum levels where there is a narrow therapeutic margin helps maintain the dose in a range where adequate therapeutic benefit is seen while avoiding toxic levels. Examples of this include Dilantin for seizures, and antibiotics like gentamicin or vancomycin.
