01Infection can stay quiet on a 20 mg course

Corticosteroids may mask some signs of infection. New infections may appear during their use. Persons on immunosuppressive doses are more susceptible to infections than healthy individuals. Chickenpox and measles can have a more serious or even fatal course in non-immune patients. A 20 mg tablet is one labelled strength used in that course.
