Symptoms and Treatment of Overdose: Overdose after incorrect topical application or due to accidental ingestion for products containing salicylates and menthol can be associated with a number of symptoms which can include: nausea, vomiting, severe abdominal pain, sweating, tinnitus, vertigo, deafness, dizziness, ataxia, headache, confusion, drowsiness and coma. As nonivamide is insoluble systemic exposure from ingestion is unlikely.
In the event of overdose, supportive care may be required. Further management should be as clinically indicated or as recommended by the national poisons center, where available.
