Betamethasone is a potent glucocorticoid steroid with anti-inflammatory and immunosuppressive properties. Unlike other drugs with these effects, betamethasone does not cause water retention. It is applied as a topical cream, ointment, foam, lotion or gel to treat itching. Betamethasone sodium phosphate is sometimes prescribed as an intramuscular injection (I.M) for itching from various ailments, including allergic reactions to poison ivy and similar plants.
Betamethasone is available in a number of compound forms:
betamethasone dipropionate (branded as Diprosone, Diprolene, Celestamine, Procort in Pakistan and others), sodium phosphate (branded as Bentelan in Italy ) and [1 ] valerate (branded as Betnovate, Celestone, Fucibet, and others). In the United States and Canada, betamethasone is mixed with clotrimazole and sold as Lotrisone and Lotriderm. It is also available in combination with salicylic acid for using in psoriatic skin conditions.
Indications [ edit ]
Betamethasone is a
corticosteroid used as a topical cream to relieve skin irritation, such as itching and flaking from eczema. It is used as a treatment for local psoriasis, as betamethasone dipropionate and salicylic acid, or as the combination betamethasone/calcipotriol. Betamethasone sodium phosphate is used orally and via injection with the same indications as other steroids.
In a randomized controlled trial Betamethasone was shown to reduce some of the ataxia symptoms associated with
Ataxia Telangiectasia (A-T) by 28-31%. [2 ]

Bethamethasone is also used prior to delivery of a
preterm baby to help prepare the lung for breathing.
Side Effects [ edit ]
Skin irritation, e.g. itching, burning, stinging. Thinning of the skin. Changes in skin pigmentation. Stretch marks (striae). Groupings of fine blood vessels becoming prominent under the skin (telangiectasia). Excessive hair growth (hypertrichosis). Prolonged use of this medicine on extensive areas of skin, broken or raw skin, skin folds or underneath airtight dressings may on rare occasions result in enough corticosteroid being absorbed to have side effects on other parts of the body, for example a decrease in the production of natural hormones by the adrenal glands.
A cream with 0.05% betamethasone appears effective in treating
phimosis in boys, and often averts the need for circumcision. [3 ] [4 ] It has replaced circumcision as the preferred treatment method for some physicians in the [5 ] British National Health Service. [6 ] [7 ]
Betamethasone is also used to stimulate fetal lung maturation (
prevention of IRDS), and to decrease the incidence and mortality from intracranial hemorrhage in premature infants.
As it crosses the placenta, which is required for its beneficial effects, it may also be associated with complications, such as
hypoglycemia and leukocytosis in newborns exposed . in utero [ ] citation needed
