How is Mexiletine Used?
Normally, mexiletine is dispensed in capsule form. However, our pharmacy can also compound mexiletine into an oral suspension that may make it easier for your pet to ingest.
What is Mexiletine Used for?
Mexiletine is primarily used for certain types of arrhythmias in dogs, specifically premature ventricular contractions (PVCs) and ventricular tachycardia. It may also be helpful in treating myotonia congenita and other myopathies.
Mexilitene is often used in dogs with PVCs and ventricular tachycardia, especially in cases where lidocaine was ineffective. It can be given both to treat these conditions and to prevent them from occuring in the future.
