What is SONE
The name of your medicine is SONE and is available in 5 mg and 25 mg tablet strengths.
The active ingredient is called prednisone.
Prednisone belongs to a group of medicines called corticosteroids.
Corticosteroids are used to help reduce inflammation in your body or suppress your
immune system, when a disease may be due to an auto-immune reaction (where your body
fights against itself).
What SONE is used for

Your doctor will be able to help decide if SONE is suitable for your condition.
Ask your doctor if you have any questions about why SONE has been prescribed for you.
If you have any concerns, you should discuss this with your doctor.
This medicine is only available with a doctor's prescription.
