The name of your medicine is Prednisolone 25mg Tablets (called Prednisolone throughout this leaflet). Prednisolone is a steroid medicine. Their full name is glucocorticoids.

How Prednisolone works
  • These corticosteroids occur naturally in the body, and help to maintain health and well-being.
  • Boosting your body with extra corticosteroid (such as prednisolone) is an effective way to treat various illnesses involving inflammation in the body.
  • Prednisolone works by reducing this inflammation, which could otherwise go on making your condition worse.
  • Prednisolone also works by stopping reactions known as autoimmune reactions. These reactions happen when your body’s immune system attacks the body itself and causes damage.
  • You must take this medicine regularly to get maximum benefit from it.

Prednisolone can be used to treat:
  • Illnesses (sometimes called collagen disease) which cause inflammation of the skin, muscles or joints. These include rheumatic fever and systemic lupus erythematosus (SLE)
  • Blood problems such as anaemia and leukaemia
  • Skin and kidney problems
  • Stomach problems such as ulcerative colitis

Do not take this medicine if:
  • You are allergic to prednisolone, or any of the ingredients in these tablets (listed in section 6)
    Signs of an allergic reaction include: rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue
  • You have an infection that affects your whole body (systemic infection), which is not already being treated

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking prednisolone.

Warnings and precautions

Talk to your doctor before you take prednisolone if:

  • You have ever had severe depression or manic-depression (bipolar disorder). This includes having had depression before while taking steroid medicines like prednisolone.
  • Any of your close family has had these illnesses.
  • You have or ever had mental problems such as ‘depression’ or ‘psychoses’

If any of the above applies to you, talk to a doctor before taking prednisolone.

Mental problems while taking prednisolone

Mental health problems can happen while taking steroids like prednisolone (see also section 4)

  • These illnesses can be serious
  • Usually they start within a few days or weeks of starting the medicine.
  • They are more likely to happen at high doses.
  • Most of these problems go away if the dose is lowered or the medicine is stopped. However, if problems do happen, they might need treatment.

Talk to a doctor if you (or someone taking this medicine), show any signs of mental problems. This is particularly important if you are depressed, or might be thinking about suicide. In a few cases, mental problems have happened when doses are being lowered or stopped.

Tell your doctor before taking this medicine if you:
  • have epilepsy (fits)
  • or anyone in your family has diabetes
  • have high blood pressure
  • have kidney, liver or heart problems
  • have brittle or weak bones (osteoporosis)
  • or anyone in your family has an eye problem called glaucoma
  • have or ever had a stomach ulcer or ulceration of the gut
  • have or ever had an infection caused by a virus or fungus. This includes infections such as athlete’s foot, thrush, and cold sores
  • have or ever had tuberculosis (TB)
  • have or are suspected of having pheochromocytoma - a tumor of the adrenal gland
  • have Scleroderma (also known as systemic sclerosis, an autoimmune disorder) because daily doses of 15 mg or more may increase the risk of a serious complication called scleroderma renal crisis. Signs of scleroderma renal crisis include increased blood pressure and decreased urine production. The doctor may advise that you have your blood pressure and urine regularly checked.

If any of the above apply to you, your doctor may want to see you more often during your treatment.

Contact your doctor if you experience blurred vision or other visual disturbances.


Prednisolone can cause enlargement of the heart in premature babies. The doctor may need to monitor babies receiving this medicine.

Other medicines and prednisolone

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription, including herbal medicines.

This is because prednisolone and other medicines can affect the way each other work.

In particular, check with your doctor if you are taking any of the following medicines.

Your doctor may want to change the dose of prednisolone, or the other medicine.

  • Painkillers such as aspirin
  • Aminoglutethimide - used for some types of cancer
  • Medicines for thinning your blood (such as warfarin)
  • Medicines for diabetes
  • Medicines for epilepsy such as phenytoin or carbamazepine
  • Medicines for tuberculosis (TB) e.g. isoniazid
  • Medicines which contain oestrogens including oral contraceptives
  • Certain antibiotics such as clarithromycin, telithromycin, erythromycin, rifampicin, rifabutin
  • Barbiturates, used as a sedative or anticonvulsant, such as phenobarbital or primidone

Some medicines may increase the effects of prednisolone and your doctor may wish to monitor you carefully if you are taking these medicines:

  • some medicines for HIV such as ritonavir, cobicistat
  • some diuretics
  • a medicine called carbenoxolone which is used to treat inflammation/ulceration of the stomach or gut


If you have just had any injections or vaccinations, tell your doctor before you take prednisolone. If you are going to have any injections or vaccinations, tell your doctor or nurse you are taking prednisolone. This includes those needed for a foreign holiday.

Some vaccines should not be given to patients taking prednisolone. This is because prednisolone can affect the way some vaccines work.


If you are going to have an operation, tell your doctor or nurse you are taking prednisolone.

Muscle relaxants are sometimes used during an operation or in an intensive care unit. These and prednisolone can affect one another.

Pregnancy and breast-feeding

  • If you do come into contact with someone with these infections, you must see your doctor or pharmacist straightaway. Your doctor may want to give you a vaccination to help stop you from getting these infections.
