Prednisolone is a man-made form of a natural substance (corticosteroid hormone) made by the adrenal gland. It is used to treat conditions such as arthritis, blood problems, immune system disorders, skin and eye conditions, breathing problems, cancer, and severe allergies. It decreases your immune system's response to various diseases to reduce symptoms such as pain, swelling and allergic-type reactions.

Take this medication by mouth, with food or milk to prevent stomach upset, exactly as directed by your doctor. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

There are many brands, strengths, and forms of liquid prednisolone available. Read the dosing instructions carefully for each product because the amount of prednisolone may be different between products. See also Precautions and Storage sections.

Follow the dosing schedule carefully. The dosage and length of treatment are based on your medical condition and response to treatment. Your doctor may direct you to take prednisolone 1 to 4 times a day or take a single dose every other day. To help you remember, mark your calendar with a reminder.

Do not stop taking this medication without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Your dose may need to be gradually decreased.

If you suddenly stop using this medication, you may have withdrawal symptoms (such as weakness, weight loss, nausea, muscle pain, headache, tiredness, dizziness). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used prednisolone for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal. See also Precautions section.

Tell your doctor if your condition lasts or gets worse.

Nausea, heartburn, headache, dizziness, menstrual period changes, trouble sleeping, increased sweating, or acne may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
