For common cold and cough symptoms, over-the-counter (OTC) medications are frequently used. These tablets often contain a combination of active ingredients designed to address various symptoms.
What ingredients are in cold and cough tablets?
Cold and cough tablets commonly include decongestants to relieve nasal stuffiness, antihistamines to reduce sneezing and runny nose, cough suppressants to quiet a cough, and expectorants to help loosen mucus [1]. Pain relievers like acetaminophen or ibuprofen may also be present to alleviate sore throat and body aches [1].
How do cold and cough tablets work?
Decongestants work by narrowing blood vessels in the nasal passages, reducing swelling and congestion. Antihistamines block the action of histamine, a chemical released during allergic reactions that causes sneezing and a runny nose. Cough suppressants, such as dextromethorphan, act on the brain's cough center to reduce the urge to cough. Expectorants, like guaifenesin, thin mucus, making it easier to cough up [2].
What are the risks of taking cold and cough medications?
Some cold and cough medications can cause drowsiness, dizziness, or a dry mouth. Certain ingredients, like decongestants, can increase blood pressure or heart rate, and should be used with caution by individuals with pre-existing cardiovascular conditions. Combining multiple medications containing the same active ingredients can lead to accidental overdose. It is important to read labels carefully and consult a healthcare professional if you have underlying health conditions or are taking other medications [3].
When should I see a doctor for a cold or cough?
A doctor should be consulted if symptoms are severe, persist for more than a week or two, or if you experience high fever, difficulty breathing, chest pain, or coughing up bloody mucus [4]. These could be signs of a more serious condition requiring medical attention.
Are there alternatives to cold and cough tablets?
Non-medicinal approaches for managing cold and cough symptoms include getting plenty of rest, staying hydrated by drinking fluids like water, herbal teas, and broths, and using a humidifier or taking steamy showers to ease congestion [4]. Throat lozenges or hard candies can also help soothe a sore throat [4].
