Symptoms: High doses of tiotropium may lead to anticholinergic signs and symptoms.
No relevant adverse events, beyond dry mouth/throat and dry nasal mucosa in a dose-dependent [10 - 40 μg daily] incidence, were observed following 14-day dosing of up to 40 μg tiotropium inhalation solution in healthy subjects with the exception of pronounced reduction in salivary flow from day 7 onwards. No significant undesirable effects have been observed in six long term studies in COPD patients when a daily dose of 10 μg tiotropium inhalation solution was given over 4 - 48 weeks.
An overdose of olodaterol is likely to lead to exaggerated effects typical of beta2-adrenergic agonists, i.e. myocardial ischemia, hypertension or hypotension, tachycardia, arrhythmias, palpitation, dizziness, nervousness, insomnia, anxiety, headache, tremor, dry mouth, muscle spasms, nausea, fatigue, malaise, hypokalaemia, hyperglycaemia and metabolic acidosis.
Therapy: Treatment with SPIOLTO RESPIMAT should be discontinued. Supportive and symptomatic treatment is indicated. Serious cases should be hospitalized. Use of cardioselective beta-blockers may be considered, but only subject to extreme caution since the use of beta-adrenergic blocker medication may provoke bronchospasm.
