Temporarily relieves sore throat pain, mouth irritation, and suppresses cough associated with common colds, flu, or minor throat infections. Often used when swallowing is painful due to throat inflammation.
Benzocaine blocks nerve signals in the affected area to produce numbness; dextromethorphan acts on the cough center in the brain to reduce cough reflex; menthol triggers cold-sensitive receptors creating a cooling effect that distracts from pain and soothes irritation.
Not suitable for children under specified age limits due to risk of serious side effects from dextromethorphan. Avoid use before eating if numbness impairs swallowing ability. Do not exceed recommended doses. Consult a healthcare provider if symptoms persist beyond 7 days or are accompanied by high fever, as this may indicate a more serious condition requiring different treatment.
