There are many cold medicines and treatments that soothe miserable cold symptoms, but there is nothing that cures a cold. Still, some cold treatments can give you much-needed relief to help you wait it out until the cold is gone. Cold medicines and treatments attack the cold symptoms, not the specific cold viruses. They don't cure the cold, but they can bring relief, lighter symptoms, or maybe even shorten your cold. For example - If you have nasal or sinus congestion, then a decongestant cold medicine can be helpful. Also, there's no one perfect cold medicine. What works for your symptoms may not help other's cold symptoms.
Often, doctors believe that a cough from a cold should not be treated unless it is keeping you up at night or interfering with your activities. Also the type of cough medicine that needs to be taken also varies and needs to be prescribed by doctors.
