Propranolol and Other Beta-Blockers: Coadministration of fluvoxamine maleate 100 mg per day and propranolol 160 mg per day in normal volunteers resulted in a mean five-fold increase (range 2 to 17) in minimum propranolol plasma concentrations.
If propranolol or metoprolol is coadministered with Fluvoxamine Maleate Tablets, a reduction in the initial beta-blocker dose and more cautious dose titration are recommended.
