Into joints (e.g., rheumatoid arthritis, osteoarthritis, pain relief)
- 0.25 to 2 mL
Into the skin (eg skin lesions, psoriasis)
- not more than 1 mL at weekly intervals
How long it is given
Your doctor will decide how long you need to have this medicine. If you have been receiving it for some time, the dose will be reduced gradually before stopping.

A single overdose of Celestone Chronodose is unlikely to cause serious side effects.
Repeated use of high doses may result in more severe side effects, as listed under Side Effects below.

While you are using Celestone Chronodose
Things you must do
If you become pregnant while being treated with Celestone Chronodose, tell your doctor immediately.
If you are having emotional or physical stress such as serious infection, surgery or injury, tell your doctor. This may affect the dose of Celestone Chronodose you need.
Check with your doctor about drinking alcohol. If you drink alcohol while receiving Celestone Chronodose, the risk of ulcers is increased.
Tell all doctors, dentists and pharmacists who are treating you that you are being treated with Celestone Chronodose.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are being treated with Celestone Chronodose.
Things you must not do
While you are being treated with Celestone Chronodose, and even after you stop it, do not have any vaccinations without your doctor's approval.
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.
All medicines have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
When this medicine is used for short periods of time, side effects are usually rare.
Ask your doctor or pharmacist any questions you may have.
