ASSESSMENT
Primary Diagnosis: ACE inhibitor-induced cough 1, 2
Rationale:
- Temporal relationship between lisinopril initiation (6 weeks ago) and cough onset (3 weeks ago) strongly suggests ACE inhibitor-induced cough, which can develop within hours to months after starting therapy 2
- Classic presentation: dry, non-productive cough with throat tickling, worse at night 2, 3
- Female gender and non-smoking status are established risk factors (females have 37.9% incidence vs. 15.5% in males) 5
- Physical examination and history exclude other common causes of chronic cough (upper airway cough syndrome, asthma, GERD) 1
- Per ACCP guidelines, ACE inhibitor should be discontinued regardless of temporal relationship, as the original cause of cough may have resolved and persisting cough could be due to the drug 1
Secondary Diagnosis: Essential hypertension, currently controlled 4
PLAN
1. ACE Inhibitor-Induced Cough Management
Immediate Action:
- Discontinue lisinopril immediately, as this is the only uniformly effective treatment (ACCP Grade B recommendation) 1, 2
- Switch to valsartan 80 mg PO daily (ACC/AHA Class I, Level A recommendation for patients intolerant to ACE inhibitors due to cough) 2, 6
- Counsel patient that cough typically resolves within 1-4 weeks after ACE inhibitor cessation, though may take up to 3 months in some patients 1, 2
Critical Pitfalls to Avoid:
- Do not attempt dose reduction of lisinopril—cough is not dose-dependent and will persist at any dosage 2
- Do not switch to alternative ACE inhibitor—cough is a class effect and will recur with any ACE inhibitor 2
- Allow at least 36 hours between last lisinopril dose and starting valsartan to minimize risk of adverse effects 2
2. Hypertension Management
Medication Changes:
- Start valsartan 80 mg PO daily (provides comparable antihypertensive efficacy to lisinopril with significantly lower cough incidence: 19.5% vs. 68.9%) 6, 7
- Target blood pressure: <130/80 mmHg
Monitoring:
- Check blood pressure, renal function (serum creatinine), and potassium levels within 1-2 weeks after starting valsartan 2
- Monitor for cough resolution at 2-week follow-up 2
3. Patient Education
- Explain that ACE inhibitor-induced cough occurs in 5-35% of patients and is a well-documented class effect 2
- Reassure that switching to ARB (valsartan) maintains cardiovascular protection with significantly lower cough risk 1, 6
- Advise to report any persistent cough beyond 4 weeks, as this may indicate alternative etiology requiring further evaluation 1
- Instruct to avoid taking any ACE inhibitor in the future 1
4. Follow-Up
- Return to clinic in 2 weeks to:
- If cough persists beyond 4 weeks on valsartan, consider alternative diagnoses (UACS, asthma, GERD) and proceed with systematic evaluation per chronic cough algorithm 1
5. Prescriptions
- Valsartan 80 mg PO daily #30, refills × 3
- Discontinue lisinopril
6. Orders
- Basic metabolic panel (BMP) in 1-2 weeks 2
