"Taking steroid tablets with other medicines, food or alcohol
Some medicines interfere with the way steroid tablets work. Tell your doctor if you take any other medicines, including herbal remedies and supplements, before starting steroid tablets.
If you're already taking steroid tablets, ask your doctor or a pharmacist for advice before taking any other medicines, remedies or supplements.
You can usually drink alcohol while taking steroid tablets, but do not drink too much as this may irritate your stomach.
You can also eat most foods while taking steroid tablets. Do not eat liquorice while taking prednisolone, however, as this can increase the amount of the medicine in your body."
