Since these symptoms point to a common cold, which is a viral infection, antibiotics will not work, as they only treat bacterial infections. For relief, you can use over-the-counter generic medications: an antihistamine (such as cetirizine or loratadine) to help with the runny nose, sneezing, and watery eyes; a cough suppressant (such as dextromethorphan) for the dry cough; and a mild pain reliever (such as paracetamol or ibuprofen) for general discomfort. Remember to get plenty of rest and stay hydrated. If your symptoms worsen or do not improve after 10 days, please consult a healthcare professional.
