Overdoses after oral use of other alpha2-agonists have been reported to cause symptoms such as hypotension, asthenia, vomiting, lethargy, sedation, bradycardia, arrhythmias, miosis, apnoea, hypotonia, hypothermia, respiratory depression and seizure.
Treatment of an oral overdose includes supportive and symptomatic therapy; a patent airway should be maintained.
No cases of overdose after cutaneous use of Mirvaso were reported during the clinical development program.
Paediatric population: Serious adverse reactions following inadvertent ingestion of Mirvaso by two young children of one clinical study subject have been reported. The children experienced symptoms consistent with previously reported oral overdoses of alpha2-agonist in young children. Both children were reported to have made a full recovery within 24 hours.
