Methasol Ophthalmic Solution

Short-term treatment of steroid responsive in inflammatory conditions of the eye after clinical exclusion of bacterial, viral or fungal infections. Non-infected inflammatory conditions of the ear or nose.

Corticosteroids bind to the glucocorticoid receptor, inhibiting pro-inflammatory signals, and promoting anti-inflammatory signals. Betamethasone phosphate has a short duration of action as it is rapidly hydrolyzed to betamethasone. Corticosteroids have a wide therapeutic window as patients may require doses that are multiples of what the body naturally produces. Patients taking corticosteroids should be counselled regarding the risk of hypothalamic-pituitary-adrenal axis suppression and increased susceptibility to infections.

Eye: 1 or 2 drops to each affected eye every 1 or 2 hours until control is achieved, then the frequency may be reduced.
Ear: 2 or 3 drops to each affected ear every 2 or 3 hours until control is achieved, then the frequency may be reduced.
Nose: 2 or 3 drops instilled into each nostril 2 or 3 times daily.
