The common cold, or upper respiratory tract infection, usually is caused by one of several respiratory viruses, Common colds are mild infections of the nose and throat, which are very common in young children (and in adults who are around them), and are caused by many different viruses. There are around 200 cold viruses, including over 100 rhinoviruses.

Sign and Symptoms

Treatment There's no cure for the common cold. Antibiotics are of no use against cold viruses.Treatment should focus on symptom relief.The most commonly used treatments include over-the-counter, antihistamines, decongestants, cough suppressants, and expectorants. These treatments can be used alone or in combination.


Pain relievers (symptomatic treatment).For fever, sore throat and headache, many people turn to acetaminophen (Tylenol, others) or other mild pain relievers.Keep in mind that acetaminophen can cause liver damage, especially if taken frequently or in larger than recommended doses. Don't give acetaminophen to children under 3 months of age.

Decongestant nasal spraysAdults shouldn't use decongestant drops or sprays for more than a few days because prolonged use can cause chronic rebound inflammation of mucous membranes. And children shouldn't use decongestant drops or sprays at all.Example: pseudoephedrine, phenlyepherine

Cough syrupsthat dextromethorphan provides a modest clinical benefit.Studies showed a reduction in the frequency and severity of cough for persons 18 years or older without significant adverse effects.Example:Codeine, dextromethorphan
