What is Prednisone for?

Prednisone belongs to the class of medications called glucocorticoids or steroid hormones like Hydrocortisone. It mainly works by reducing inflammation with a wide range of uses such as treating moderate to severe rheumatoid arthritis, acute asthma, exacerbations of chronic obstructive pulmonary disease, allergies and idiopathic thrombocytopenic purpura.

How to use it?

Prednisone is taken by mouth usually in the form of regular tablets. Regular release tablets are typically taken once daily in the morning. Low-dose modified-release tablets (Lodotra) are taken at bedtime and may be useful in people who have morning stiffness from rheumatoid arthritis. It is advised to take Prednisone with food or milk to reduce gastrointestinal upset. Modified-release tablets should be swallowed whole, and should not be crushed or chewed. You should take Prednisone as directed by your doctor. Long-term treatment with Prednisone is usually tapered slowly. Do not stop taking Prednisone without professional advice.


Prednisone has a wide variety of dosages and uses. The usual adult dose range may vary from 1 to 50 mg per day. Your doctor will prescribe the appropriate dose for your medical condition. Because regular prednisone tablets are only available in 5 mg tablets, it is normal to take multiple tablets per day. For example, if your dose is 30 mg daily, will need to take six 5 mg Prednisone tablets.
