BENZODIAZEPINES AND CALCIUM-CHANNEL BLOCKERS - MIDAZOLAM OR TRIAZOLAM

The serum levels and effects of midazolam are markedly increased by diltiazem or verapamil. This also occurs with triazolam and diltiazem, and is predicted to occur with triazolam and verapamil.
Monitor the outcome of concurrent use. Consider using a lower initial dose of midazolam or triazolam.
