Absence of fever, tachypnoea and chest signs rule out the risk of complications, the BTS has said.
Chest radiography should be recommended if a child has an acute-onset cough that fails to resolve in two to three weeks. The possibility of an inhaled foreign body and suspicions of pneumonia also warrant referral for chest X-ray.
The BTS reiterated that over-the-counter antihistamines and antihistamine-decongestant combinations were no more effective than a placebo.
Antibiotics and bronchodilators are also not recommended for common head colds.
