Taking paracetamol for a few days, if you can tolerate it, is preferable to putting your steroid dose back up again. Paracetamol is complementary to prednisolone and will not interfere with its action. NSAIDs such as ibuprofen should not be taken when you are on steroids for GCA or PMR. But do discuss pain relief with your doctor. Don’t be a martyr to pain.
