Inhalation route (Powder)
Mannitol acts as a bronchoconstrictor and may cause severe bronchospasm. Mannitol bronchial challenge testing is for diagnostic purposes only and should be conducted only by trained professionals under a physician familiar with the test and management of acute bronchospasm (ie, testing area equipped with appropriate medications and equipment). Immediately administer a short-acting inhaled beta-agonist in the event of severe bronchospasm. Do not perform bronchial challenge testing with mannitol in a patient with asthma or very low baseline pulmonary function tests (eg, FEV1 less than 1 to 1.5 L or less than 70% of the predicted values).

For Healthcare Professionals
Applies to mannitol: compounding powder, inhalation kit, intravenous solution, irrigation solution
Cardiovascular side effects have included hypotension and tachycardia. Venous thrombosis or phlebitis extending from the injection site and hypervolemia have occurred rarely and are generally associated with the solution or technique used in administration.[Ref]
Respiratory side effects have included pulmonary congestion and rhinitis. Respiratory side effects associated with mannitol (the active ingredient contained in Bronchitol) inhalation have included cough, gagging, wheeze, and decreased forced expiratory volume.[Ref]
Metabolic side effects have included fluid and electrolyte imbalance, acidosis, and electrolyte loss.[Ref]
Nervous system side effects have included headache, convulsions, and dizziness.[Ref]
Hematologic side effects have included thrombophlebitis.[Ref]
Eight cases of mannitol (the active ingredient contained in Bronchitol) IV overdose in patients with preexisting renal failure were reviewed. Symptoms presented in the reviewed cases were CNS involvement out of proportion to uremia, severe hyponatremia, large osmolality gap, and fluid overload. Six patients were treated with hemodialysis, one patient with peritoneal dialysis, and one patient died before initiation of treatment. All patients received large doses over 1 to 3 days with a mean dose of 310 +/- 182.8 g. CNS involvement consisted of CNS depression, confusion, lethargy, stupor, and coma. Two patients recovered cerebral function and continued on lifetime dialysis, 3 patients recovered renal and cerebral function, and 1 patient recovered renal function but had severe cerebral dysfunction.[Ref]
Renal side effects have included acute renal failure.[Ref]
Local side effects have included extravasation. This effect is generally attributed to the solution or technique used in administration.[Ref]
Ocular side effects have included blurred vision.[Ref]
Immunologic side effects have included infection at the injection site and febrile response. These effects are usually attributed to solution or technique used in administration.[Ref]
A 75-year-old woman with severe major depression experienced a manic episode 30 minutes after initiation of a 20% mannitol (the active ingredient contained in Bronchitol) intravenous infusion for the treatment of acute angle closure glaucoma. The patient had been started on nortriptyline 50 mg per day for the treatment of depression ten days earlier. She received oral acetazolamide, topical pilocarpine, topical timolol, and topical dexamethasone concomitantly for the treatment of glaucoma. The mania resolved within approximately 1 hour following discontinuation of the mannitol infusion, and the patient returned to a severe depressive state. An extensive lab evaluation, toxicology screening, and medical examination failed to show additional secondary causes for mania in this patient.[Ref]
Psychiatric side effects have rarely included mania (1 case report).[Ref]
