Hi Julie, Don't worry, if your child's levels have been consistantly good then it sounds like you have a good pharmacy. I am sure he is using the Cortef tablet to make the suspension. Alot of pharmacists will be crushing the tablets and compounding their own suspension now . If you are at all still concerned, ask the pharmacist where he got the "compounding stability data". Perhaps Upjohn provided the info when it first went off the market. Good Luck,
