Interactions with other medicines

• Medicines that affect the CYP2D6 and CYP1A2 liver enzymes, such as propafenone and fluvoxamine, can change the amount of Mexiletine in your blood. Your doctor may increase the dose slowly.
• Combining Rhymex with lidocaine or tocainide may increase side effects involving the nervous system.
• Combining it with other antiarrhythmic medicines such as quinidine, procainamide or disopyramide may have additive effects, and your doctor may need to adjust the dose.
• Medicines that speed up liver enzymes, such as phenytoin, rifampicin and phenobarbital, can lower the level of mexiletine. Your doctor may need to change your dose when these medicines are started or stopped.
• Cimetidine may change how much mexiletine is absorbed. Your doctor will monitor you for side effects.
• Mexiletine may raise theophylline levels, which can cause nausea, vomiting and tremor. Your doctor may monitor theophylline levels and lower the dose.
• Narcotic pain relievers, anticholinergic medicines, and antacids containing magnesium hydroxide or aluminium hydroxide may delay the absorption of mexiletine. No change in dose is usually needed.
• Cardiac glycosides, diuretics and blood thinners (anticoagulants) have been used with mexiletine without serious problems, but your doctor may adjust doses if needed.
• Medicines or diets that significantly change the acidity of your urine can change how quickly mexiletine leaves the body. Avoid these unless your doctor advises otherwise.
• Mexiletine may cause false-positive results on some rapid urine drug screens, particularly for amphetamines. Tell the lab or your doctor you are taking it.
