What is Betamethasone for?
Betamethasone belongs to a class of medications called glucocorticoids or steroid hormones. It mainly works by reducing inflammation with a wide range of uses, including:
– Short-term local treatment of inflammation
– Eczemas unresponsive to less potent corticosteroids
– Suppression of inflammatory and allergic disorders
– Oral ulceration
How to use it?
You can take Betamethasone by mouth as tablets or capsules. It is more commonly used as cream or ointment by directly applying sparingly to the affected skin areas. If you are taking it orally, the usual daily dose ranges from 0.5 to 5 mg for adults. If you are using creams or ointments, apply sparingly to the affected areas 1-2 times a day.
What are the side effects of Betamethasone?
When used as a cream or ointment, minimise the period of time you use Betamethasone as long-term use can cause skin thinning. When Betamethasone is taken by mouth for long-term use, it can have more serious side effects such as anxiety, cataracts, cognitive impairment, fat redistribution (moon face and buffalo hump), fluid retention, gastrointestinal discomfort, headache, impaired wound healing, high blood pressure, increased risk of infection, menstrual cycle irregularities, and osteoporosis.
Who should not take Betamethasone?
– People allergic to Betamethasone or any component of the formulation
– Patients with bacterial, fungal or viral skin lesions, acne or rosacea
– Patients with systemic fungal infections or herpes simplex of the eye
– Betamethasone is a moderately potent corticosteroid. Use the lowest dose possible for the shortest period of time (particularly on the face). Long term oral use can suppress the hypothalamus-pituitary gland-adrenal gland axis.
– Do not use topical Betamethasone on broken or inflamed skin.
– Apply thinly onto the affected areas. Usually one fingertip unit (from the very end of the finger to the first crease in the finger) of topical steroid (the tube is assumed to have a 5 mm nozzle) is enough for a skin area twice the size of an adult’s hand (the flat side) with all fingers together.
– Avoid contact with eyes and mucous membranes.
– Report signs of new or worsening infections
– After long-term use of this drug, contact your doctor/pharmacist if you notice fatigue, weight gain, or thinning of skin that bruises easily.
Common dosing schedule:
You can take oral Betamethasone with or without food.
Do not use topical Betamethasone more than 2 times each day.
This schedule is for reference only, adjustments may be made according to individual needs.
