4 mg dexamethasone phosphate in 1 ml ampoule (4 mg/ml) for IM or IV injection or infusion

Symptomatic treatment of severe allergic and inflammatory reactions Dosage varies according to indication, reaction severity and clinical response: Child: 0.15 to 0.6 mg/kg (max. 16 mg) by IM or IV injection once daily Adult: 0.5 to 24 mg by IM or IV injection once daily Duration varies according to indication. Due to dexamethasone’s long half-life, a treatment of 1 or 2 days is usually sufficient in asthma or croup. For longer treatments, change to oral route as soon as possible. In the event of treatment longer than 10 days, decrease doses gradually to avoid adrenal suppression. Foetal lung maturation Administer to the mother: 6 mg by IM injection every 12 hours for 2 days (total dose: 24 mg)

Foetal lung maturation: after 34 weeks of gestation, corticosteroid treatment is not indicated; dexamethasone may be replaced by betamethasone: 2 doses of 12 mg by IM injection at 24- hour interval (total dose: 24 mg). 0.75 mg of dexamethasone has the same anti-inflammatory activity as 5 mg of prednisolone or prednisone and 20 mg of hydrocortisone. Dexamethasone acetate, insoluble in water, is a suspension used only for local treatment: intra- articular or peri-articular injection, epidural injection (sciatica).
