Competing Clocks: How Alcohol Timing Quietly Undermines Dexamethasone Metabolism
Most patients on dexamethasone therapy never receive guidance on how alcohol consumption — particularly its timing relative to dosing — can meaningfully alter drug metabolism, reduce therapeutic efficacy, and amplify adverse effects. Understanding the pharmacokinetic competition at the liver's cytochrome P450 enzyme system reveals why even moderate, socially accepted drinking patterns can quietly work against corticosteroid treatment outcomes.
