Things to be careful of
If Celestone Chronodose is injected into one of your joints, you should be careful not to put too much stress or strain on that joint for a while, even if it begins to feel better. Make sure your doctor has told you how much you are allowed to move this joint while it is healing.
If redness or swelling occurs at the place of injection, and continues or gets worse, check with your doctor.
Always check with your doctor as soon as possible if you notice any signs of a possible infection, such as sore throat, fever, sneezing or coughing. Celestone Chronodose may lower your resistance and make any infection you do get harder to treat.
If you are having any laboratory tests, tell your doctor. Celestone Chronodose may give false results in skin tests.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using Celestone Chronodose.
