| ===CONTRAINDICATIONS===
| |
| | |
| Verapamil hydrochloride injection is contraindicated in:
| |
| | |
| 1. Severe [[hypotension ]]or [[cardiogenic shock]].
| |
| | |
| 2. [[Second-|Second-degree AV block]] or [[third-degree AV block]] (except in patients with a functioning artificial ventricular pacemaker).
| |
| 3. [[Sick sinus syndrome]] (except in patients with a functioning artificial ventricular [[pacemaker]]).
| |
| | |
| 4. Severe [[congestive heart failure]] (unless secondary to a supraventricular tachycardia amenable to verapamil therapy).
| |
| | |
| 5. Patients receiving intravenous[[ beta blockers|beta-adrenergic blocking ]]drugs (e.g., [[propranolol]]). Intravenous verapamil and intravenous beta-adrenergic blocking drugs should not be administered in close proximity to each other (within a few hours), since both may have a depressant effect on myocardial contractility and AV conduction.
| |
| | |
| 6. Patients with[[ atrial flutter]] or [[atrial fibrillation]] and an accessory bypass tract (e.g., [[Wolff- Parkinson-White]], Lown-Ganong-Levine syndromes) are at risk to develop ventricular [[tachyarrhythmia ]]including [[ventricular fibrillation]] if verapamil is administered. Therefore, the use of verapamil in these patients is contraindicated.
| |
| | |
| 7. Ventricular tachycardia: Administration of intravenous verapamil to patients with wide-complex [[ventricular tachycardia]] (QRS ≥ 0.12 sec) can result in marked hemodynamic deterioration and ventricular fibrillation. Proper pretherapy diagnosis and differentiation from wide-complex [[supraventricular tachycardia ]]is imperative in the emergency room setting.
| |
| | |
| 8. Known [[hypersensitivity ]]to verapamil hydrochloride.<ref name="dailymed.nlm.nih.gov">{{Cite web | last = | first = | title = VERAPAMIL HYDROCHLORIDE INJECTION, SOLUTION [CARDINAL HEALTH] | url = http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=0c27c868-7eae-4b3e-babf-e89404ea27b7#nlm34090-1 | publisher = | date = | accessdate = }}</ref>
