3.9.1 Cough suppressants

Prescribing Notes

• Patients with acute cough should be advised that most coughs go away on their own within 3 weeks and to see a GP if the cough persists for more than 3 weeks. For more information refer to nidirect.
• Cough may be a symptom of an underlying disorder (e.g. asthma, COPD, GORD, rhinitis) which should be addressed.
• Cough may be a side effect of a drug (e.g. ACE inhibitors), or it can be associated with smoking or environmental pollutants.
• Cough can also have a significant habit component.
• There is little evidence to support the use of cough suppressants in COPD and asthma.
• Cough suppressants are available to purchase over the counter.
