H2-RECEPTOR ANTAGONISTS AND QUINIDINE
Cimetidine can raise quinidine serum levels and toxicity may develop in some patients.
Be alert for changes in the response to quinidine if cimetidine is started or stopped. Ideally the quinidine serum levels should be monitored and the dosage reduced as necessary. Reductions of 25 to 35% have been suggested.
