What is prednisolone used for?

Prednisolone is used to treat many different conditions, including:

• severe allergies
• asthma
• arthritis
• skin problems
• inflammatory diseases of the bowel
• autoimmune diseases, where your immune system mistakenly attacks normal cells in your body.

It helps reduce inflammation in your body.

Symptoms of inflammation may include swelling, redness, pain, tenderness or itching in any part of your body.

How does prednisolone work?

Prednisolone enters the cells that cause inflammation and blocks the body’s inflammatory reaction. It reduces the symptoms of some conditions, but is not a cure.

What forms of prednisolone are available?

Prednisolone is the name of the active ingredient. It is available in many different brands, which have different:

• names
• appearances (size, shape or colour)
• forms (tablets, liquid, eye drops and suppositories)

No matter which brand you are prescribed, prednisolone works in the same way to treat your condition.

Risk and benefits of prednisolone

Prednisolone helps most people who take it, but some people experience side effects.

Generally, the risk of side effects is low if you take prednisolone for a short time. Your risk increases if you take high doses of prednisolone for a long time.

Common side effects of prednisolone, especially with high doses for long periods, include:

• fluid retention, which can lead to heart problems
• trouble sleeping
• bloating of the face and swelling of the abdomen
• weight gain
• irregular periods
• muscle cramps
• thin skin with easy bruising and acne

Less common side effects of prednisolone include:

• headaches
• diarrhoea or constipation
• nausea, vomiting or anorexia
• cataracts
• increased frequency or severity of infections
• reduced thyroid function

Some side effects can only be picked up by your doctor. If you take prednisolone for long periods of time, you should have regular check-ups.

See your doctor immediately or go to the emergency department of your nearest hospital if you experience any of these serious side effects:

• severe stomach or gut pain
• epileptic fits
• sudden changes in your vision
• symptoms such as severe dizziness, fainting, weakness, chest pain or irregular heart beat
• mental disturbances

It is important to take prednisolone as prescribed. Talk with your doctor if you would like to lower your dose or stop taking prednisolone. Stopping it suddenly might cause side effects.

For more information, read the Consumer Medicines Information (CMI) for the brand of prednisolone you are taking.
