Cough OTC

It’s the time of year where we get more questions on cold and cough. Usually coughs are treated with over the counter products and many patients don’t know which product to choose. There are a few reasons we should send these patients to the doctor. Some examples of exclusion criteria include: cough for more than 7 days, fever, production of green/thick mucus, or chest pain. Codeine is one of the most effective drugs at decreasing cough, but some pharmacies don’t readily offer these formulations over the counter. Dextromethorphan is in many combination products and is available OTC. This product is recommended for patients with a non-productive cough and works by suppressing the cough. Diphenhydramine can also be used to help with cough. This can especially benefit patients with other cold-like symptoms or if they are having trouble sleeping. Guaifenesin is an expectorant and should be used for patients with a productive cough. It loosens and thins secretions, making it easier to cough out the mucus and clear the lungs. Staying hydrated, using lozenges, and using a humidifier are some non-drug methods you can suggest to patients who have a cough.
