Over-the-Counter Medications for Cold and Cough Relief
Many over-the-counter (OTC) medications are available to help manage the symptoms of cold and cough. These include antitussives, decongestants, antihistamines, expectorants, and non-steroidal anti-inflammatory drugs (NSAIDs) Edwards2023Simasek2007Kim2009+2 MORE. The choice of medication depends on the specific symptoms and the age of the patient.
Antitussives and Cough Suppressants
Dextromethorphan is commonly recommended for treating cough in adults, but its effectiveness in children and adolescents is not well established Edwards2023Simasek2007. Codeine and hydrocodone are not recommended for coughs caused by the common cold due to lack of evidence and potential risks . Plant-derived substances like menthol and eucalyptus, found in some OTC remedies, may help reduce cough and irritation by acting on specific receptors in the airways .
Decongestants for Nasal Symptoms
Pseudoephedrine and phenylephrine are effective decongestants for relieving nasal congestion in adults and adolescents, but should be used for no more than three days to avoid rebound symptoms Edwards2023Simasek2007Fashner2012. Inhaled ipratropium can also help with nasal symptoms in older children and adults Simasek2007Fashner2012.
Antihistamines and Combination Therapies
First-generation antihistamines can help with symptoms, especially if cold symptoms interfere with sleep, but they may cause drowsiness Edwards2023Simasek2007. Combination antihistamine/decongestant products can modestly improve symptoms in adults, but newer nonsedating antihistamines are not effective for cough . In children, antihistamines are not recommended for cold symptoms due to lack of benefit and potential harm Fashner2012Summerlin2025.
Expectorants and Herbal Remedies
Guaifenesin is widely used as an expectorant, but recent evidence questions its effectiveness in relieving upper respiratory symptoms . Some herbal products, such as ivy leaf extract and combinations of thyme and primrose root, have shown benefits for productive cough, while others are supported mainly by traditional use . Buckwheat honey and Pelargonium sidoides (geranium) extract may also help improve symptoms in children .
NSAIDs and Analgesics
NSAIDs like ibuprofen can relieve pain, headache, and muscle aches associated with the common cold, but do not significantly reduce cough or nasal discharge Kim2009Fashner2012. They are useful for managing discomfort but do not shorten the duration of the illness .
Safety Considerations, Especially in Children
OTC cough and cold medications can pose significant risks to children, especially those under four years old. Serious adverse effects, including toxicity and even fatalities, have been reported with improper use or accidental overdose Diantini2024Summerlin2025. The FDA does not recommend the use of antihistamine or decongestant-containing products in children younger than two years . Non-pharmacologic therapies, such as humidified air, fluids, and honey (for children over one year), are safer alternatives for young children Simasek2007Fashner2012Summerlin2025.
Complementary and Alternative Therapies
Most complementary therapies, such as Echinacea and vitamin C, are not recommended for treating cold symptoms, though vitamin C may modestly reduce the duration of illness if taken regularly Simasek2007Fashner2012. Prophylactic use of zinc and probiotics may reduce the incidence of colds in children .
Single-Symptom vs. Multi-Symptom Medications
There is debate over whether multi-symptom, multi-component OTC products are better than single-symptom treatments. The best approach depends on the patient’s specific symptoms and medical history .
Conclusion
OTC medications for cold and cough can help relieve symptoms, but their effectiveness varies by ingredient, age group, and symptom type. Dextromethorphan and pseudoephedrine are commonly recommended for cough and nasal congestion in adults, while first-generation antihistamines may help with sleep. NSAIDs are useful for pain relief. In children, caution is needed due to safety concerns, and non-drug therapies are often preferred. Herbal remedies and plant-derived substances may offer additional symptom relief, but evidence varies. Always consider patient age, symptoms, and safety when choosing a treatment.
