Nursing Considerations for Generic Drugs
• Administer intravenous verapamil with compatible solutions, including Ringer's injection, D5W, or normal saline solution.
• Maintain continuous electrocardiogram monitoring and keep emergency resuscitative equipment and drugs readily available during intravenous therapy.
• Assess patient with hypertrophic cardiomyopathy or idiopathic hypertrophic subaortic stenosis for early development of hypotension and pulmonary edema because second-degree atrioventricular block and sinus arrest can result.
• Assess for bradycardia and hypotension, and notify prescriber if heart rate or blood pressure declines significantly.
• Disopyramide or flecainide shouldn't be given within 48 hours before or 24 hours after verapamil because additive negative inotropic effects can result.
• Institute measures to prevent constipation, including a high-fiber diet and a stool softener, as prescribed.
