The Oxandrolone hormone does not carry any estrogenic related side effects. It does not aromatize and cannot lead to gynecomastia or water retention due to increases in estrogen levels. It further carries no progestin related activity, which again supports no estrogenic related side effects. Due to water retention being impossible with this steroid, this will decrease the risk of high blood pressure. Excess water retention can promote high blood pressure. Some steroids that do not aromatize can lead to high blood pressure, such as Trenbolone , but Anavar is rarely associated with this trait.
The use of antibiotics and short-acting beta-2-agonist bronchodilators in children with typical croup are rarely indicated because of the low incidence of bacterial infection (<1:1000 cases of croup) as well as for physiological reasons. An otorhinolaryngology (ORL) consultation for airway evaluation is indicated when croup symptoms are persistently severe despite treatment. Outpatient referral to ORL is recommended for children with multiple croup episodes and for those who present outside the usual age group for typical croup ( Figure 1 ).
