Prednisone (oral steroids)

Prednisone is in a class of medicines known as corticosteroids, which are similar to the steroid hormones your body naturally makes. Prednisone is different to the steroids athletes take to build muscle (anabolic steroids).

Prednisone is used to treat many illnesses related to inflammation. For example, it's used to treat allergies, asthma, COPD, rheumatoid arthritis, gout, ulcerative colitis, Crohn's disease and other auto-immune diseases. Prednisone calms or suppresses the body's immune system to reduce inflammation anywhere in the body. This helps to reduce the symptoms associated with these conditions, especially in flare‑ups. It doesn't cure them.

Prednisone dosage

Your dose of prednisone will depend on which condition you're being treated for and how you respond.

Doses range from 5 mg to 60 mg daily. Some people may need a short course of prednisone (such as five days), while others may need to take it for longer (weeks to months).

Prednisone tablets come in different strengths. Check the strength of your tablets and your prescribed dose. Often you may need to take more than one tablet. If you're unsure about your dose or the number of tablets to take, ask your pharmacist.

Always take your prednisone exactly as your general practice team has told you. The pharmacy label on your medicine will tell you how much prednisone to take, how often to take it and any special instructions.

How to take prednisone

Special instructions

If you get sick

If you're taking 20 mg or less of prednisone daily, it's important that you increase your dose if you get sick: When people get sick or have an accident, their body usually makes more cortisol to help them recover. If someone cannot make this extra cortisol, they might go into shock or collapse unless they get extra steroids.

Possible side effects

Like all medicines, prednisone can cause side effects, although not everyone gets them. Most side effects are to do with how much prednisone you're taking and for how long.

Side effects

What to do

Trouble sleeping

Take prednisone in the morning or at least three hours before bedtime.

Headache, weak muscles, feeling tired

These are common when you first start taking prednisone and usually go away with time. Tell your general practice team if troublesome.

Fluid retention causing swollen ankles and feet

Whenever possible, sit with your feet raised. Avoid foods with high salt content. Tell your general practice team if this happens.

If you have diabetes, you may need to increase the dose of your diabetes medication to control your blood glucose. Talk to your general practice team.

Your general practice team will monitor your blood glucose levels regularly if you're at risk of getting diabetes.

You should have your blood pressure checked regularly. If it goes up, you may need treatment to bring it down.
