Side effects are minimized by taking the lowest doses possible (that still yields positive results) and following doctor's orders. It is important to avoid self-regulation of the dosage, either by adding more or stopping the drug without a schedule. After prolonged use, steroids must be gradually reduced to permit the adrenal glands to resume natural cortisol production. Eliminating doses too quickly can result in glucocorticoid withdrawal symptoms, worsening of underlying inflammatory disease (rebound effect), or rarely, adrenal crisis (a life-threatening state caused by insufficient levels of adrenal steroids).
The original brand name of oxandrolone was Anavar, which was marketed in the United States and the Netherlands .   This product was eventually discontinued and replaced in the United States with a new product named Oxandrin, which is the sole remaining brand name for oxandrolone in the United States.   Oxandrolone has also been sold under the brand names Antitriol ( Spain ), Anatrophill ( France ), Lipidex ( Brazil ), Lonavar ( Argentina , Australia , Italy ), Protivar, and Vasorome ( Japan ) among others.     Additional brand names exist for products that are manufactured for the steroid black market.
