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.
LIFESTYLE AND HOME REMIDIES .
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
