Betamethasone is a moderate-potent glucocorticoid steroid with anti-inflammatory and immunosuppressive abilities, used especially where water retention is undesirable. It is applied as a topical cream, ointment, foam, lotion or gel to treat itching (e.g. from eczema).
It is available as a number of esters: Dipropionate (branded as Diprosone, Diprolene and others), Sodium Phosphate and Valerate (branded as Betnovate, Celestone and others).
Betamethasone sodium phosphate is sometimes prescribed as an intramuscular
injection (I.M) for itching from various ailments including allergic reactions to
Indications
Betamethasone is a corticosteroid used to stimulate fetal lung maturation, and to decrease the incidence and mortality from intracranial hemorrhage in premature infants.
It is also used as a topical cream to relieve skin irritation.
0.05% Betamethasone cream appears effective in treating phimosis in boys, and often averts the need for circumcision.
Betamethasone sodium phosphate is used orally and via injection with the same indications as other steroids.
Fetal risk
As it crosses the placenta, which is required for its beneficial effects, it may also be associated with complications, such as hypoglycemia and leucocytosis in newborns exposed in utero.
