Left ventricular failure with labetalol.
  1. M. A. Frais,
  2. T. J. Bayley


    A patient treated for hypertension with labetalol developed left ventricular failure. When the drug was withdrawn and the BP controlled with 2 other agents, the signs of heart failure regressed. The ill effects in this case could have been because the beta-blocking effects of labetalol are 4 to 6 times greater than the alpha-blocking effects. Caution should be exercised when prescribing this drug for patients with heart failure or with previous symptoms.
