 One of the advantages of linezolid is its high bioavailability ( close to 100 % ) when given by mouth : the entire dose reaches the bloodstream , as if it had been given intravenously . This means that people receiving intravenous linezolid may be switched to oral linezolid as soon as their condition allows it , whereas comparable antibiotics ( such as vancomycin and <unk> / <unk> ) can only be given intravenously . Taking linezolid with food somewhat slows its absorption , but the area under the curve is not affected .
