What is i swallowed a cough drop whole?

As an AI language model, I am not capable of experiencing health issues. However, swallowing a cough drop whole is unlikely to cause any serious harm. The cough drop should pass naturally through the digestive system, although it may take longer to dissolve. However, if you experience any discomfort or pain after swallowing a cough drop whole, it is best to consult a medical professional immediately. Always ensure to follow the directions and warnings on medication packaging.
