Intal (cromolyn sodium) is an anti-inflammatory drug indicated in the management of patients with bronchial asthma. Intal is available as a generic drug. Common side effects of Intal include throat irritation or dryness, unusual or unpleasant taste in your mouth, cough, wheezing, nausea, heartburn, stomach pain, sneezing, stuffy or itchy nose, watery eyes, burning or bleeding of your nose, urinating more or less than usual, dizziness, drowsiness, or headache.
Intal inhaler delivers about 800 mcg per inhalation. For management of bronchial asthma in adults and pediatric patients (5 years of age and over), the usual starting dosage is two metered inhalations four times daily at regular intervals. This dose should not be exceeded. Effective Intal Inhaler therapy is dependent upon its administration at regular intervals, as directed. Intal may interact with other medicines in a nebulizer. Tell your doctor all medications and supplements you use. Intal Inhaler should be used during pregnancy only if clearly needed. Adverse effects of this drug could become apparent only after many years; a benefit/risk consideration of the long-term use of the Intal Inhaler is particularly important in pediatric patients.
