Expected symptoms[edit | edit source]

The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of any of the symptoms listed under ADVERSE REACTIONS, eg, seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats per minute, arrhythmias, nervousness, headache, tremor, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, and insomnia.

Abuse and treatment of Proventil HFA[edit | edit source]

Hypokalemia may also occur. As with all sympathomimetic medications, cardiac arrest and even death may be associated with abuse of Proventil HFA Inhalation Aerosol. Treatment consists of discontinuation of Proventil HFA Inhalation Aerosol together with appropriate symptomatic therapy. The judicious use of a cardioselective bete-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of Proventil HFA Inhalation Aerosol. Return to top

Lethal dosing[edit | edit source]

The oral median lethal dose of albuterol sulfate in mice is greater than 2000 mg/kg (approximately 6800 times the maximum recommended daily inhalation dose for adults on a mg/m2basis and approximately 3200 times the maximum recommended daily inhalation dose for children on a mg/m2basis). In mature rats, the subcutaneous median lethal dose of albuterol sulfate is approximately 450 mg/kg (approximately 3000 times the maximum recommended daily inhalation dose for adults on a mg/m2basis and approximately 1400 times the maximum recommended daily inhalation dose for children on a mg/m2basis). In young rats, the subcutaneous median lethal dose is approximately 2000 mg/kg (approximately 14,000 times the maximum recommended daily inhalation dose for adults on a mg/m2basis and approximately 64000 times the maximum recommended daily inhalation dose for children on a mg/m2basis). The inhalation median lethal dose has not been determined in animals. Return to top
