Abstract:
A patient who received tocolysis with nifedipine developed neuromuscular blockade after 500 mg of magnesium sulfate was administered. This reaction demonstrates that nifedipine can seriously potentiate the toxicity of magnesium. Caution should be exercised when these two tocolytics are combined.
