Parkinsonism unmasked by verapamil.
We report the case of a 55-year-old man who had a parkinsonian syndrome unresponsive to levodopa for 5 years and had been taking verapamil during the past 8 years. Parkinsonian signs improved markedly after withdrawal of verapamil, suggesting its role in unmasking the parkinsonism. To our knowledge, this side effect of verapamil has not been described previously.
