Summary

What this interaction means in plain words
Calcium carbonate and Prednisolone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Calcium carbonate belongs to Gastrointestinal Tract; Prednisolone belongs to Endocrine.
Why it happens
