Alternatively, after a baseline plasma cortisol determination, 1 mg may be given at 11 pm and plasma cortisol determined at 8 am the next morning. Plasma cortisol and urinary output of 17-OHCS are depressed after dexamethasone admin in normal individuals but remain at basal levels in patients with Cushing's syndrome.
Acute exacerbations in multiple sclerosis
Adult: 30 mg daily for 1 wk followed by 4-12 mg daily for 1 mth.

Lactation: Drug excreted in breast milk; not recommended
Pregnancy-Lactation
Pregnancy
Corticosteroids readily cross the placenta
Adverse developmental outcomes including orofacial clefts (cleft lip with or without cleft palate), intrauterine growth restriction, and decreased birth weight have been reported with maternal use of corticosteroids during pregnancy
Pregnancy testing is recommended for females of reproductive potential before initiating treatment
Contraception
Use effective contraception during treatment and for at least 1 month following final dose
Infertility in males
Steroids may increase or decrease motility and number of spermatozoa in some patients
In animals, dexamethasone affects male spermatogenesis
Lactation
Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects
Advise women not to breastfeed during treatment and for 2 weeks after the last dose
Interactions
Increased risk of hypokalaemia when used concurrently with potassium-depleting drugs such as amphotericin B and loop diuretics. Reduces efficacy of isoniazid, salicylates, vaccines and toxoids. Increased activity of dexamethasone and cyclosporin when used together. Concurrent use with aspirin or ethanol may lead to increased GI side effects.
Potentially Fatal: Reduced efficacy in combination with ephedrine, cholestyramine, phenytoin, phenobarbital and rifampicin.
