If you have diabetes, be aware that corticosteroids may decrease glucose tolerance and raise blood sugar.

If you have hypercoagulation disorder (increased blood clotting), note that corticosteroids can increase blood coagulation and cause blood clots.

Corticosteroids can cause or worsen psychiatric problems, including depression, euphoria, mood swings, and personality changes.

Corticosteroids can worsen strongyloides infection.

If you are pregnant, planning to become pregnant, or may be pregnant, note that the health of your baby may be at risk if you take a corticosteroid during the first trimester. It is not known whether corticosteroids are safe for pregnant women in later trimesters.

Oral corticosteroids can limit growth in children. They should be taken at the lowest effective dose. The child's growth should be monitored during treatment.

Corticosteroids can be passed into breast milk. They may not be good options for breastfeeding women.

  • tuberculosis or a positive TB screening test
  • heart failure
  • herpes infection of the eye
