Tablet: The initial dosage of Hydrocortisone Tablets may vary from 20 mg to 240 mg of hydrocortisone per day depending on the specific disease entity being treated. In situations of less severity, lower doses will generally suffice, while in selected patients higher initial doses may be required. The initial dosage should be maintained or adjusted until a satisfactory response is noted. If after a reasonable period of time there is a lack of satisfactory clinical response, Hydrocortisone Tablets should be discontinued and the patient transferred to other appropriate therapy. 

It should be emphasized that dosage requirements are variable and must be individualized on the basis of the disease under treatment and the response of the patients. After a favorable response is noted, the proper maintenance dosage should be determined by decreasing the initial drug dosage in small decrements at appropriate time intervals until the lowest dosage which will maintain an adequate clinical response. It should be kept in mind that constant monitoring is needed in regard to drug dosage. If, after long-term therapy the drug is to be stopped, it is recommended that it be withdrawn gradually, rather than abruptly.
