Symptoms of the common cold start gradually over several days and usually last about two weeks. Symptoms may include sneezing, a stuffy or runny nose, sore throat, cough, watery eyes, mild headache, or body aches. A cold will go away on its own without treatment. However, there are many nonprescription products that may help relieve some of the symptoms of a cold. Cold medicines often contain more than one ingredient and are used to treat more than one symptom. Read the labels and buy products that have only the ingredients that you need. If you are not sure which medicine is best, ask your pharmacist.
Decongestants reduce swelling in your nose and sinuses. They may also lessen the amount of mucus made by your nose. If you use decongestants more often than directed, your stuffy nose may get worse.
Antihistamines block the effect of histamine. Histamine is a chemical your body makes when you have an allergic reaction. Antihistamines are most often used to treat itchy or watery eyes or a stuffy or runny nose caused by an allergy. Antihistamines probably won't help a stuffy or runny nose caused by a cold because they make mucus thick and dry.
Mucolytics are medicines that make mucus thinner so that it is easier to cough up out of your throat and lungs.
Expectorants are cough medicines that may help to keep the mucus thin and bring up mucus from the lungs when you cough. This may relieve chest congestion and make it easier to breathe.
Cough suppressants (antitussives) are medicines that lessen the urge to cough. They may give relief from a dry, hacking cough. If you have a cough that is wet sounding and produces mucus, it is important for you to cough the mucus up out of your lungs. For this reason, cough suppressants are not recommended for a wet sounding cough.
Fever and pain relievers, such as acetaminophen, aspirin, or other nonsteroidal anti-inflammatory drugs (NSAIDs), are often included in cold medicine. Read labels carefully to avoid taking more medicine than you need.
If you have any questions, ask your healthcare provider or pharmacist for more information. Be sure to keep all appointments for provider visits or tests.
