Consumer:Using morphine together with mexiletine may decrease the effects of mexiletine. Contact your doctor if your condition changes. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications.

Professional:MONITOR: Opioids may reduce the rate of absorption and onset of action of oral mexiletine. The mechanism is delayed gastric emptying by the opioid. Clinical data are limited. Plasma levels of mexiletine were decreased by 31% to 50% after 3 hours in patients who had also received diamorphine or morphine, compared to patients who did not receive opioids. Subtherapeutic mexiletine levels occurred in 47% of patients who received diamorphine and in 25% of patients who received morphine.
MANAGEMENT: Monitoring for altered efficacy is advisable.
