Closely monitor blood pressure every 15 minutes initially, then adjust frequency based on patient response and stability. Target a gradual reduction, not a rapid drop.
Continuously assess for hypotension; this is the most common adverse effect. Prepare to manage it with intravenous fluids and possibly vasopressors.
Observe for signs of hyperkalemia, including muscle weakness, fatigue, and arrhythmias. Regularly check serum potassium levels.
Monitor renal function with serum creatinine and BUN measurements, especially in patients with pre-existing renal impairment. Adjust dosage accordingly.
Assess for angioedema, characterized by facial swelling. Immediately discontinue captopril and initiate appropriate management if this occurs.
Document all vital signs, lab results, and any adverse reactions meticulously. This detailed record aids in effective treatment and risk mitigation.
Consider continuous electrocardiogram (ECG) monitoring in high-risk patients, particularly those with cardiac arrhythmias or pre-existing kidney disease.
Educate the patient about potential side effects and the importance of reporting any unusual symptoms promptly to healthcare providers.
