Dosage and Administration
Prednisolone acetate or sodium phosphate is applied topically to the eye. Care should be taken to avoid contamination of the tip of the ointment tube or dropper when the drug is used ophthalmically.
Potency of some sodium phosphate preparations is expressed in terms of prednisolone phosphate.
For use in the eye, 1 or 2 drops of prednisolone acetate ophthalmic suspension or prednisolone sodium phosphate ophthalmic solution may be instilled into the conjunctival sac every hour during the day and every 2 hours during the night for initial therapy in severe cases. In mild or moderate inflammation or when a favorable response is attained in severe cases, dosage may be reduced to 1 or 2 drops every 3-12 hours.
Alternatively, prednisolone sodium phosphate ophthalmic ointment may be instilled into the conjunctival sac 3 or 4 times daily initially, and once or twice daily thereafter. The ointment also may be used at night in conjunction with daytime use of a suspension or solution to reduce the frequent applications required with the liquid dosage forms.
The lowest effective concentration should be used and, if improvement does not occur within several days, the drug should be discontinued and other therapy begun. The duration of treatment depends on the type and severity of the disease and may range from a few days to several weeks; long-term therapy should be avoided. When the drug is discontinued, dosage should be gradually tapered to avoid exacerbation of the disease.
