Question: what is the best over the counter medicine for runny nose and sneezing?
Answer: Runny Nose, Watery Eyes, and Sneezing When you have a cold, your body makes chemicals called histamines. That leads to sneezing, a runny nose, and watery eyes. Over-the-counter antihistamines such as chlorpheniramine and diphenhydramine block this process and can relieve those symptoms.
