Prednisolone is a corticosteroid that may be used to reduce inflammation and calm down an overactive immune system. It works by mimicking the effects of cortisol, a hormone released by the adrenal glands (located on top of the kidneys) that regulates metabolism and stress. Prednisolone prevents the release of substances in the body that cause inflammation.

Prednisolone is used to treat many different inflammatory conditions such as arthritis, lupus, psoriasis, ulcerative colitis, allergic disorders, gland (endocrine) disorders, and conditions that affect the skin, eyes, lungs, stomach, nervous system, or blood cells.

Prednisolone has predominantly glucocorticoid activity, which means it mainly affects our immune response and reduces inflammation, rather than affecting the body's balance of electrolytes and water (this is called mineralocorticoid activity).

Prednisolone was FDA approved in 1955.

You should not use prednisolone if you have a fungal infection anywhere in your body.

Prednisolone comes as a tablet, an orally disintegrating tablet (tablet that dissolves quickly in the mouth), a solution (liquid), and as a suspension (liquid) to take by mouth with food. Your doctor will probably tell you to take your dose(s) of prednisolone at certain time(s) of day every day. Your personal dosing schedule will depend on your condition and on how you respond to treatment. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take prednisolone exactly as directed. Do not take more or less of it or take it more often or for a longer period of time than prescribed by your doctor.

To take the orally disintegrating tablet, use dry hands to peel back the foil packaging. Immediately take out the tablet and place it on your tongue. The tablet will quickly dissolve and can be swallowed with or without water. Do not chew, split, or break the tablet.

Your doctor may change your dose of prednisolone during your treatment to be sure that you are always taking the lowest dose that works for you. Your doctor may also need to change your dose if you experience unusual stress on your body such as surgery, illness, infection, or a severe asthma attack. Tell your doctor if your symptoms improve or get worse or if you get sick or have any changes in your health during your treatment.

If you are taking prednisolone to treat an ongoing condition, this medication may help control your condition but will not cure it. Continue to take prednisolone even if you feel well. Do not stop taking prednisolone without talking to your doctor. If you suddenly stop taking prednisolone, your body may not have enough naturally produced steroids to function normally. This may cause symptoms such as extreme tiredness, weakness, slowed movements, upset stomach, weight loss, changes in skin color, sores in the mouth, and craving for salt. Call your doctor if you experience these or other unusual symptoms while you are taking decreasing doses of prednisolone or after you stop taking the medication.

Take prednisolone exactly as prescribed by your doctor. Your doctor may occasionally change your dose. Do not use prednisolone in larger or smaller amounts or for longer than recommended.

Prednisolone is sometimes taken every other day. Follow your doctor's dosing instructions very carefully.

Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

You may need to shake the oral suspension (liquid) well just before you measure a dose. Follow the directions on your medicine label.

Keep prednisolone disintegrating tablets in their blister pack until you are ready to take the medicine. Open the package using dry hands, and peel back the foil from the tablet blister (do not push the tablet through the foil). Remove the tablet and place it in your mouth. Allow the disintegrating tablet to dissolve in your mouth without chewing. Swallow several times as the tablet dissolves. If desired, you may drink liquid to help swallow the dissolved tablet.

Your dose needs may change if you have unusual stress such as a serious illness, fever or infection, or if you have surgery or a medical emergency. Tell your doctor about any such situation that affects you.

Prednisolone can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using prednisolone.

You should not stop using prednisolone suddenly. Follow your doctor's instructions about tapering your dose.

Wear a medical alert tag or carry an ID card stating that you take prednisolone. Any medical care provider who treats you should know that you take steroid medication.

If you need surgery, tell the surgeon ahead of time that you are using prednisolone. You may need to stop using the medicine for a short time.

Store prednisolone at room temperature away from moisture and heat.

You should not use prednisolone if you are allergic to it, or if you have:

• a fungal infection anywhere in your body.

Prednisolone can weaken your immune system, making it easier for you to get an infection. Steroids can also worsen an infection you already have, or reactivate an infection you recently had. Tell your doctor about any illness or infection you have had within the past several weeks.

To make sure prednisolone is safe for you, tell your doctor if you have ever had:

• active tuberculosis;

• a thyroid disorder;

• herpes infection of the eyes;

• stomach ulcers, ulcerative colitis, or diverticulitis;

• depression, mental illness, or psychosis;

• liver disease (especially cirrhosis);

• high blood pressure;

• osteoporosis;

• a muscle disorder such as myasthenia gravis; or

• multiple sclerosis.

Also tell your doctor if you have diabetes. Steroid medicines may increase the glucose (sugar) levels in your blood or urine. You may also need to adjust the dose of your diabetes medications.

It is not known whether prednisolone will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether prednisolone passes into breast milk or if it could affect the nursing baby. Tell your doctor if you are breast-feeding.

Call your doctor for instructions if you miss a dose of prednisolone.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

An overdose of prednisolone is not expected to produce life threatening symptoms. However, long term use of high steroid doses can lead to symptoms such as thinning skin, easy bruising, changes in the shape or location of body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from light, excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Your doctor may instruct you to follow a low-salt, high potassium, or high calcium diet. Your doctor may also prescribe or recommend a calcium or potassium supplement. Follow these directions carefully.

Do not receive a "live" vaccine while using prednisolone. The vaccine may not work as well during this time, and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.

Do not receive a smallpox vaccine or you could develop serious complications.

Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chickenpox or measles. These conditions can be serious or even fatal in people who are using steroid medication.

Get emergency medical help if you have signs of an allergic reaction to prednisolone.: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Prednisolone may cause serious side effects. Call your doctor at once if you have:

• shortness of breath (even with mild exertion), swelling, rapid weight gain;

• bruising, thinning skin, or any wound that will not heal;

• severe depression, changes in personality, unusual thoughts or behavior;

• new or unusual pain in an arm or leg or in your back;

• bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds;

• severe pain in your upper stomach spreading to your back, nausea and vomiting;

• a seizure (convulsions); or

• low potassium--leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination, numbness or tingling.

Steroids can affect growth in children. Tell your doctor if your child is not growing at a normal rate while using prednisolone.

Common side effects of prednisolone may include:

• fluid retention (swelling in your hands or ankles);

• dizziness, spinning sensation;

• changes in your menstrual periods;

• headache;

• muscle pain or weakness; or

• stomach discomfort, bloating.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Other drugs may interact with prednisolone, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your body's response to prednisolone.

If you are having any skin tests such as allergy tests or tuberculosis tests, tell the doctor or technician that you are taking prednisolone.

If you have diabetes, prednisolone may increase your blood sugar level. If you monitor your blood sugar (glucose) at home, test your blood or urine more frequently than usual. Call your doctor if your blood sugar is high.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
