The common cold is the most frequent illness managed in general practice. Despite a long search for a cure only potential treatments for the symptoms have been established. Colds afflict most adults two to four times a year and children four to eight times a year, and the resulting hours of absenteeism from work or school have enormous economic bearings. Several viruses can cause the common cold, but rhinoviruses are by far the most common. Studies evaluating various treatments for the common cold are divided into experimentally induced and naturally occurring colds. Treatments studied included symptomatic measures, pharmacological blockers, and specific antiviral agents, as well as drugs with yet unestablished mechanism of action. A systematic, evidence based assessment of this literature is imperative for rational selection of treatment—if any—for patients with a common cold.
Alleviation of symptoms remains the only proved way to treat the common cold. First generation antihistamines, anticholinergics, and α agonists effectively reduce rhinorrhea and sneezing, but have minimal effects on other symptoms. Antitussive agents are probably of minimal benefit
Over-the-counter cold treatments are effective only in adults and adolescents
Antiviral drugs such as interferon alfa-2b are effective only if taken before symptoms develop
Zinc may reduce the duration and intensity of symptoms but a safe effective dose is not yet established
Mast cell stabilisers have shown promising results but have not been evaluated in large trials
Overuse of cold treatments by both doctors and patients is a major problem requiring education of both parties
I reviewed articles cited in Medline between 1966 and 1997 using the keywords common cold, treatment, therapy, and drug treatment. I selected well designed randomised, double blind, placebo controlled trials and authoritative review articles on specific topics in treatment of the common cold. Articles published within the past five years were selected …
