A corticosteroid with a mainly glucocorticoid action and moderate anti-inflammatory effects (ATC D07AB), slightly higher than that of prednisolone (ATC D07AA). Indicated inhaled use in the treatment of inflammatory diseases of the respiratory system: bronchitis, asthma, rhinitis, etc. This comment is about inhaled triamcinolone. Since the last update we have not found published data about its excretion in breast milk. After inhaled administration, the bioavailability is 25% (Argenti 1999) and the plasma levels reached are clinically insignificant (Zaborny 1992). There is consensus among experts that, in general, neither systemic corticoids nor inhaled ones present a breastfeeding contraindication (National Asthma Education 2004). Corticoids are of commonally used in pediatrics and have no side effects when they are used in isolation or in short-term treatments. See below the information of these related products:
