Safe Use of Cough and Cold Medicines
WHAT YOU NEED TO KNOW:
What do I need to know about cough and cold medicines?
Over-the-counter (OTC) cough and cold medicines contain 1 or more ingredients used to decrease cough and cold symptoms. OTC cough medicine may contain an antitussive, expectorant, or both. Antitussives decrease cough by blocking your cough reflex. Expectorants thin your mucus to help clear it from your airway. Cold medicines may have any combination of a cough medicine, antihistamine, decongestant, and pain medicine. Antihistamines may help reduce runny nose and sneezing. Decongestants may help to reduce nasal congestion (stuffiness). Pain medicines also help to decrease a fever.
Who should not take OTC cough and cold medicines?
People with certain medical conditions should talk to their healthcare provider before taking OTC cough or cold medicines. Examples include high blood pressure, irregular heartbeat, or liver disease. Decongestants, antihistamines, and medicines high in sodium (salt) can raise blood pressure. If you are pregnant or breastfeeding, ask your healthcare provider if you can take these medicines.
How do I safely take OTC cough and cold medicines?
- Read the directions on the label to learn how much medicine you should take and how often to take it. Do not take more than the recommended amount. Choose medicine that decreases the symptoms you have.
- Do not combine cough and cold medicines together or with pain medicine. Different cold medicines may contain the same ingredient. For example, cold medicines may contain acetaminophen. When you take more than one type of medicine, you may take too much of the same ingredient.
