There is no clinical syndrome associated with an overdosage of cromolyn sodium. Acute toxicity testing in a wide variety of species has demonstrated an extremely low order of toxicity for cromolyn sodium, regardless of whether administration was parenteral, oral or by inhalation. Parenteral administration in mice, rats, guinea pigs, hamsters and rabbits demonstrated an LD₅₀ in the region of 4000 mg/kg. Intravenous administration in monkeys also indicated a similar order of toxicity. The highest dose administered by the oral route in rats and mice was 8000 mg/kg and at this dose level no deaths occurred. By inhalation, even in long term studies, it proved impossible to achieve toxic dose levels of cromolyn sodium in a range of mammalian species.

Nasal Solution: Cromolyn sodium nasal solution is contraindicated in those patients who have shown hypersensitivity to any of the ingredients.
