This medication is used to treat a certain bowel condition (ulcerative colitis). While budesonide does not cure this condition, it may decrease symptoms such as pain and diarrhea. Budesonide is an anti-inflammatory drug (corticosteroid hormone). It works by decreasing the body's natural defense response (immune response).

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This medication may also be used for Crohn's disease.

Read the Patient Information Leaflet if available from your pharmacist before you start taking budesonide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once daily in the morning. Swallow this medication whole with a full glass of water (8 ounces/240 milliliters) unless your doctor directs you otherwise. Do not crush or chew the tablets. Doing so can release all of the drug at once, increasing the risk of side effects.

The dosage and length of treatment are based on your medical condition and response to treatment.

Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.

If you are regularly taking a different corticosteroid by mouth (such as prednisone), you should not stop taking it unless directed by your doctor. Some conditions (such as asthma, allergies) may become worse when the drug is suddenly stopped. If you suddenly stop taking the drug, you may also have withdrawal symptoms (such as weakness, weight loss, nausea, muscle pain, headache, tiredness, dizziness). To help prevent withdrawal, your doctor may slowly lower the dose of your old medication after you begin taking budesonide. Tell your doctor or pharmacist right away if you have withdrawal. See also Precautions section.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.

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.

Tell your doctor if your condition does not get better or if it gets worse.

This medication usually has fewer side effects than other corticosteroids because budesonide works in the gut and only small amounts are absorbed into the body. Nausea, abdominal pain, or headache may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Because this drug works by weakening the immune system, it may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as sore throat that doesn't go away, fever, chills). This medication may sometimes cause oral thrush or a new yeast infection. Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.
