What is can eating too many cough drops kill you?

As an AI language model, my responses are based on research and resources available to me. Here's what I found:

Cough drops typically contain menthol, which is a mild anesthetic that numbs the throat and reduces coughing. Menthol, in large amounts, can cause serious health problems like difficulty breathing, seizures, and even coma. However, to consume enough cough drops to cause such severe effects is very rare and unlikely.

Consuming excessive amounts of cough drops containing other ingredients like acetaminophen (pain reliever), dextromethorphan (cough suppressant), and antihistamines (allergy relief) may also cause serious health problems like liver damage, respiratory depression, and cardiac arrest.

Therefore, it is important to follow the recommended dosage and warnings on the label and seek medical attention if you experience any adverse effects. In general, it is unlikely that consuming a few extra cough drops will cause serious harm, but consuming a large number of them certainly can be dangerous.
