What is Despec Drops?
Dextromethorphan is a medicine that helps stop coughing. It works by affecting the brain signals that cause the cough reflex.
Guaifenesin is a medicine that helps clear mucus from your chest and throat, making it easier to cough it out.
Pseudoephedrine is a decongestant that narrows blood vessels in the nasal passages. When blood vessels are widened, it can lead to nasal congestion (stuffy nose).
Despec Drops is a combination medicine used to relieve cough, stuffy nose, sinus congestion, and chest congestion caused by allergies, the common cold, or the flu.
Despec Drops will not treat a cough caused by smoking, asthma, or emphysema.
Despec Drops may also be used for other purposes not mentioned in this medication guide.
