Indications & Uses

Pulmicort is indicated for:

Pharmacology

Budesonide is a synthetic corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity. It has roughly 200 times greater affinity for the glucocorticoid receptor and about 1000 times greater topical anti-inflammatory potency than cortisol. Corticosteroids have been shown to have a wide range of inhibitory effects against multiple cell types (such as mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (such as histamine, eicosanoids, leukotrienes, and cytokines) involved in allergy related inflammation.

Cautions & Contraindications

Warnings & Precautions

Pulmicort nasal spray should be used carefully in patients who have active or dormant tuberculosis, an untreated fungal, bacterial, or systemic viral infection, or ocular herpes simplex. It should not be used by patients who have had a recent nasal septal ulcer, nasal surgery, or nasal injury.

Contraindications

Budesonide should not be used for acute breathlessness or status asthmaticus. For these conditions, short-acting β-sympathomimetics and other bronchodilators are the medicines to use.

Pregnancy & Breastfeeding

Pregnancy: The FDA has placed inhaled budesonide in pregnancy category B. In animal studies, high inhaled doses have not shown the drug to be teratogenic. Even with those animal findings, the chance of fetal harm looks remote when the inhaled form is used during pregnancy. Still, because human studies cannot fully rule out risk, inhaled budesonide should be used in pregnancy only when it is clearly needed.

Lactation: Only minute amounts of inhaled budesonide pass into breastmilk, so an infant's exposure is negligible. Reviewers and an expert panel regard inhaled corticosteroids as acceptable to use while breastfeeding. Taken by mouth, budesonide has an oral bioavailability of only about 9%, so any budesonide that reaches the breastmilk is likely to be absorbed by the infant at a similarly low level.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Use in Special Populations

Children using budesonide are at risk of slowed growth, so their growth should be monitored.

Overdose

As with other corticosteroids given into the nose, a sudden overdose of budesonide is unlikely, because the bottle holds only a small total amount of the active ingredient. Even if someone used the whole bottle at once, by mouth or into the nose, clinically significant systemic side effects would most likely not occur. Long-term overdosage is a different matter, and it may lead to signs and symptoms of hypercorticism.

⚠️ In an emergency call 999 or go to the nearest hospital emergency department.

Storage

Store Budesonide below 30°C, and keep it away from light and moisture. Keep it out of the reach of children.
