Other symptoms which should be reported immediately include difficulty in breathing, swelling of the face, white patches in the throat, mouth, or nose, irregular menstrual periods, severe acne, and on rare occasions, behavioral changes (mostly affecting children)

Contraindications
Budesonide is contraindicated as a primary treatment of status asthmaticus or other acute episode of asthma where intensive measures are required. It is also contraindicated for patients who have hypersensitivity to budesonide. Interactions
Those taking tablets or capsules orally should avoid grapefruit and grapefruit juice and echinacea. : 160 
Grapefruit juice may double bioavailability of oral budesonide. Echinacea diminishes bioavailability.Also, high-fat meals delay absorption but do not impede absorption. Pharmacology
Budesonide is an agonist of glucocorticoid receptors. Among its effects are:

Controls the rate of protein synthesis. Depresses the migration of polymorphonuclear leukocytes and fibroblasts. Reverses capillary permeability and lysosomal stabilization at the cellular level to prevent or control inflammation. Has a potent glucocorticoid activity and weak mineralocorticoid activity. Pharmacokinetics
Onset of action: Nebulization: 2–8 days; Inhalation: 24 hours; Nasal: 10 hours
Peak effect: Nebulization: 4–6 weeks; Inhalation: 1–2 weeks
Distribution: 2.2-3.9 L/kg
Protein binding: 85% to 90%
Metabolism: Hepatic via CYP3A4 to two metabolites: 16 alpha-hydroxyprednisolone and 6 beta-hydroxybudesonide; minor activity
Budesonide is extensively metabolized in first pass, resulting in a low bioavailability and systemic effects
Bioavailability: Capsule: 9% to 21%; Nebulization: 6%; Inhalation: 6% to 13%
Half-life elimination: 2–3.6 hours
Time to peak: Capsule: 0.5–10 hours (variable in Crohns disease); Nebulization: 10–30 minutes; Inhalation: 1–2 hours; Tablet: 7.4-19.2 hours
Excretion: urine (60%) and feces as metabolites. Chemistry
Budesonide, also known as 11β,21-dihydroxy-16α,17α-(butylidenebis(oxy))pregna-1,4-diene-3,20-dione, is a synthetic pregnane steroid and non-halogenated cyclic ketal corticosteroid.
Dermatofibrosarcoma protuberans (DFSP)   is a rare locally aggressive malignant cutaneous soft-tissue sarcoma. DFSP develops in the connective tissue cells in the middle layer of the skin (dermis). Estimates of the overall occurrence of DFSP in the United States are 0.8 to 4.5 cases per million persons per year. In the United States, DFSP accounts for between 1 and 6 percent of all soft tissue sarcomas  and 18 percent of all cutaneous soft tissue sarcomas. In the Surveillance, Epidemiology and End Results (SEER) tumor registry from 1992 through 2004, DFSP was second only to Kaposi sarcoma. Presentation
Dermatofibrosarcoma protuberans begins as a minor firm area of skin most commonly about  to 1 to 5 cm in diameter. It can resemble a bruise, birthmark, or pimple. It is a slow-growing tumor and is usually found on the torso but can occur anywhere on the body. About 90% of DFSPs are low-grade sarcomas. About 10% are mixed, containing a high-grade sarcomatous component (DFSP-FS); therefore, they are considered to be intermediate-grade sarcomas. DFSPs rarely lead to a metastasis (fewer than 5% metastasize), but DFSPs can recur locally. DFSPs most often arise in patients who are in their thirties but this may be due to diagnostic delay. Location
Commonly located on the chest and shoulders, the following is the site distribution of DFPS as was observed in Surveillance, Epidemiology, and End Results (SEER) [1] database between 2000 and 2010.
