Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known major interaction flagged in FDA labeling, attributed to current medical studies do not show a clear way these two drugs interfere with each other when used for heart attacks.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
