• Assess hydration status. Increase patient's fluid input to help moisten secretions.
• Advise patient to avoid irritants, such as smoking, dust, and fumes. Suggest use of humidifier to filter air pollutants.
• Inform patient that treatment aims to decrease coughing frequency and intensity without completely eliminating protective cough reflex.
• Instruct patient to contact health care provider if cough lasts more than 7 days.
• As appropriate, review all other significant adverse reactions and interactions, especially those related to the drugs and behaviors mentioned above.
