In
medicine, a course of
medication is a period of continuous treatment with a drug, sometimes with variable dosage. Treatment with some drugs should not end abruptly. Instead, their course should end with a tapering dosage.
AntibioticsTaking the full course of antibiotics is important to prevent reinfection and/or development of drug-resistant bacteria.
SteroidsFor both short-term and long-term steroid treatment, when stopping treatment, the dosage is tapered rather than abruptly ended. This permits the
adrenal glands to resume the body's natural production of
cortisol. Abrupt discontinuation can result in
adrenal insufficiency; and/or steroid withdrawal syndrome — a rebound effect in which exaggerated symptoms return.
