Hi and thank you so much for this query. I am so sorry to hear about this flare up. Prednisolone is a good drug to contain flare up. It is relatively safe and most side effects would only set in should you use it for longer periods. None of the medications used is without side effects. Other drug alternatives include sulfasalazine, mesalamine, azathioprine, etc. Talk to your doctor about the concerns with steroids and let me hi if other alternatives would make a better choice. I hope you find this useful. I wish you well. Feel free to request for more information and ask ore questions should need be. Thanks.
