When patients present with respiratory illnesses, pharmacists must assess factors such as comorbidities, symptoms and symptom control, medication history, and adverse effects. The first question they should ask is, “Does this patient have a known respiratory diagnosis?” While investigating accessible health records, including the patient’s pharmacy profile, in search of a diagnosis, it is important to keep an eye out for comorbidities that can affect treatment choice.

Next, pharmacists can evaluate the patient’s respiratory symptom control. If the symptoms are controlled, the pharmacist should review medication doses and ensure that the patient is on the lowest dose necessary to control symptoms. If the patient lacks adequate symptom control, however, the pharmacist can evaluate the patient’s understanding of the medication regimen and ability to use devices, if the regimen requires them.

If the patient is adherent to a medication regimen, the pharmacist can suggest an OTC medication or reach out to the health care provider and suggest a step-up of therapy or a dose increase.

If the patient is nonadherent, the pharmacist can assess the reason and counsel on proper medication use and techniques to help with adherence.

Finally, a pharmacist can ask patients if they are experiencing adverse effects or adverse drug reactions and suggest changes in therapy when necessary.

A cough is a nonspecific symptom that may signify a number of potential health concerns. A cough can be classified based on its duration. If the cough lasts for up to 3 weeks, it is considered acute; 3 to 8 weeks, subacute; and more than 8 weeks, chronic.

An acute cough has many potential causes, and the patient’s symptoms and medical history may serve as clues (table 1

The common cold is the most frequent cause of an acute cough. This mild upper respiratory viral illness is usually caused by rhinovirus. Adults average 2 to 3 colds annually, while children average more.

 Symptoms can be alleviated with OTC medications (figure 1

). Patients can also use nonpharmacological options, including avoiding irritants such as smoke, drinking water, instilling saline drops or spray in the nose, and using a cool vaporizer or a humidifier. If the cough lingers, a comorbidity may be the cause (table 2

Asthma and chronic obstructive pulmonary disease (COPD) are the most common chronic respiratory illnesses. In 2016, 26.5 million Americans had active asthma.

 Chronic lower respiratory disease, primarily COPD, was the third-leading cause of death in the United States in 2014.

 Pharmacists must assess patients’ symptom control and counsel patients on proper inhaler technique and regimen adherence, as described above.

Certain red flags suggest serious health concerns (figure 2

). When speaking with patients, always look for these concerning symptoms and know when to suggest a visit to the doctor or emergency department.
