When the symptoms of sneezing and runny nose appear, the first thing to do is to clarify whether it is caused by cold or allergy. If the sneezing and runny nose is caused by allergy, you can use antihistamines to relieve the symptoms, such as cetirizine and loratadine. If the sneezing and runny nose is caused by a cold, you can take a combination cold medicine containing decongestants or antihistamines to relieve it.
