Adverse events were not observed in animal reproduction studies. No data available on whether cromolyn crosses the placenta or clinical effects on the fetus. Available evidence suggests safe use during pregnancy.
Prevents the mast cell release of histamine, leukotrienes, and slow-reacting substance of anaphylaxis by inhibiting degranulation after contact with antigens

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience diarrhea, nausea, abdominal pain, or headache. Have patient report immediately to prescriber wheezing, cough, muscle pain, muscle weakness, shortness of breath, excessive weight gain, or swelling of arms or legs (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
