Hi krysse,
Just a few additional comments above what has been said so far:
-avoid any beverage containing quinine, Schweppes, for example,
-pred lowers potassium in blood, some supplement (bananas, nuts...) is advised but not to much as potassium may interfere with cardiac functions,
-cortisone interferes also with calcium absorption and may lead to osteoporosis, calcium + vitamine D3 supplements are thus welcome...
-pred should be taken in the morning, preferably during breakfast to avoid sleep disturbances.
Take good care of your in-law!
Maurice.
