Hello @shonnie, Welcome to Connect. I've had various teas when my PMR was active and I was taking prednisone but I wasn't aware of any drug interactions. The Rheumatoid Arthritis Foundation has some information on the topic here -- What Teas can you have while on Prednisone?: https://www.helpfightra.org/teas-while-on-prednisone/. The article does recommend talking with your doctor. Your pharmacist may be the best source for any drug interactions with prednisone. I did a check on Drugs.com and found no interactions but I would still talk with my doctor -- https://www.drugs.com/interactions-check.php?drug_list=1936-0,2284-10628

If your doctor doesn't have an answer, can you ask your pharmacist?
