Cough Management in Hypertensive Patients

Medication Recommendations

Oral decongestants should be used with extreme caution or avoided entirely in patients with hypertension, as they can elevate blood pressure, according to the Journal of Allergy and Clinical Immunology 1
Most OTC combination cold medications are not recommended, with the exception of older antihistamine-decongestant combinations, though even these carry hypertension concerns, as stated by Chest and American Family Physician 2, 3, 4
Codeine (30 mg three times daily) or dextromethorphan (30 mg as needed) are recommended for short-term symptomatic relief in chronic bronchitis (Grade B recommendation), according to Chest 2, 3
Central cough suppressants like codeine and dextromethorphan have limited efficacy for URI-related cough and are not recommended (Grade D recommendation), as reported by Chest 2, 3
First-generation antihistamines (like diphenhydramine) combined with decongestants are recommended for acute cough from the common cold, but the decongestant component poses hypertension risk, according to American Family Physician 4
Ipratropium bromide is the only inhaled anticholinergic specifically recommended for cough suppression (Grade A recommendation for URI/chronic bronchitis), as stated by Chest 2, 3, 5

If the hypertensive patient is taking an ACE inhibitor, this is the most common medication-related cause of persistent dry cough, occurring in 5-35% of patients, according to Praxis Medical Insights 6, 7
Discontinuing the ACE inhibitor is the only uniformly effective treatment, with cough resolution expected within 1-4 weeks, as reported by Praxis Medical Insights 6, 7
The American College of Cardiology strongly recommends (Grade A) switching to an angiotensin receptor blocker (ARB) when ACE inhibitor-induced cough occurs, according to Praxis Medical Insights 6
Losartan 25 mg once daily is the most studied ARB for patients with ACE inhibitor-induced cough, with titration to 50 mg if needed for blood pressure control, as stated by Praxis Medical Insights 6

The American College of Cardiology recommends determining if the patient is on an ACE inhibitor and switching to an ARB if necessary, as reported by Praxis Medical Insights 6, 7
For symptomatic cough relief while maintaining blood pressure control, the first-line treatment is benzonatate, followed by ipratropium bromide inhaler, and then codeine or dextromethorphan, according to Chest and Praxis Medical Insights 2, 5, 6, 7
Oral decongestants and most OTC combination products should be avoided entirely, as stated by Journal of Allergy and Clinical Immunology, Chest, and American Family Physician 1, 2, 3, 4
