Cold, cough, and allergy symptoms often show up together. This can happen because of a viral infection, allergies, dust, changes in the weather, or irritation in your nose and throat. You might notice sneezing, a runny nose, watery eyes, throat irritation, a mild fever, or a cough that is either dry or has mucus. The right medicine depends on whether your symptoms are caused by allergies, a virus, or if your chest is involved. Doctors usually recommend antihistamines for sneezing and a runny nose, and may suggest different cough syrups depending on the type of cough. Simple home remedies like steam inhalation, drinking warm fluids, saltwater gargles, and staying away from dust or smoke can also help soothe your throat and nose. Some cold medicines can make you sleepy or cause dryness, especially if they have several ingredients. Most of the time, antibiotics are not needed for a regular viral cold unless there is a strong reason to think you have a bacterial infection. If you have a high fever, trouble breathing, chest pain, wheezing, thick yellow mucus, or if your symptoms last for many days, you should consult a doctor for a closer check.
