Management of Common Cold

Pharmacological Treatment

Paracetamol (acetaminophen) is recommended for relieving nasal obstruction, rhinorrhea, and pain in patients with common cold, with a dosage of 500-1000mg every 4-6 hours (max 4000mg daily), as suggested by the American Academy of Otolaryngology 1
Antihistamines, such as diphenhydramine (Benadryl), have limited short-term benefit (days 1-2) for overall symptoms in patients with common cold, but may cause drowsiness, especially first-generation antihistamines 1
Decongestants, such as xylometazoline (Otrivin), have a small positive effect on nasal congestion in patients with common cold, but should be used for ≤3 days to avoid rebound congestion, as recommended by the American Academy of Otolaryngology 1
Ipratropium bromide nasal spray (Ipravent) is recommended for relieving rhinorrhea in patients with common cold, as suggested by the European Rhinologic Society 1, 2
NSAIDs like ibuprofen (Brufen) are recommended as an alternative for headache, ear pain, muscle/joint pain in patients with common cold, with significant benefits, as suggested by the American College of Physicians and the European Rhinologic Society 1, 3
Dextromethorphan-containing products (Benadryl DR) are recommended for short-term relief of dry cough in patients with common cold, as suggested by 4
Zinc lozenges (zinc acetate or gluconate) at ≥75 mg/day started within 24 hours of symptom onset significantly reduce cold duration, as recommended by the European Rhinologic Society 1

Nasal saline irrigation, adequate hydration, and rest are recommended as adjunctive treatments for common cold, as suggested by the American Academy of Otolaryngology and the European Rhinologic Society 1, 3, 5
Honey is recommended for cough in patients with common cold older than 1 year, as suggested by the American Academy of Otolaryngology 1
Regular, moderate-intensity exercise may help prevent common colds, as suggested by 1
Probiotics may be beneficial for prevention, though evidence quality is low, as suggested by 1

Antibiotics have no benefit for viral common cold and increase the risk of adverse effects, according to the American College of Physicians, the European Rhinologic Society, and the European Society of Clinical Microbiology and Infectious Diseases 3, 1, 5
Exceeding recommended dosages, particularly with paracetamol, can cause liver damage, as warned by the American Academy of Otolaryngology 1
Prolonged decongestant use (>3 days) can lead to rebound congestion, as warned by the American Academy of Otolaryngology 1
Overlooking combination ingredients can risk duplicate dosing, and over-the-counter cold medications should not be used in children younger than four years, as warned by the American Academy of Otolaryngology 1

Patients should seek medical attention if they experience signs of bacterial complications or if symptoms persist beyond 2 weeks, develop high fever after the first few days of illness, severe facial pain or headache, shortness of breath or wheezing, or complete voice loss or severe hoarseness persisting more than 2-3 weeks, as advised by the American College of Physicians 3, 6
Patient education about the viral nature of the illness and expected duration of symptoms is crucial to manage patient expectations and reduce unnecessary antibiotic use, as emphasized by the American Academy of Family Physicians and the American College of Physicians 3, 1
The common cold is self-limiting and typically resolves within 7-10 days, though symptoms can last up to 2 weeks, as stated by the American College of Physicians and the American Academy of Family Physicians 3, 3
