- BRAND NAME (Manufacturer)
-
- Mexitil (Boehringer Ingelheim)
-
- TYPE OF DRUG
-
- Antiarrhythmic
-
- INGREDIENT
-
- mexiletine
-
- DOSAGE FORM
-
- Capsules (150 mg, 200 mg, and 250 mg)
-
- STORAGE
-
- Mexiletine should be stored at room temperature in a tightly closed
- container. It should not be exposed to high temperatures.
-
- USES
-
- Mexiletine is used to treat arrhythmias (irregular heart rhythms). This
- medication works through the suppression of irregular heartbeats and the
- establishment of a more normal rhythm.
-
- TREATMENT
-
- Mexiletine can be taken with meals or an antacid to decrease stomach
- irritation.
- Try to take mexiletine at the same times each day. This medication is
- most effective when the amount of the drug in your bloodstream is kept at a
- constant level. Mexiletine should, therefore, be taken at evenly spaced
- intervals day and night. For example, if you are supposed to take mexiletine
- three times per day, the doses should be spaced eight hours apart. Your
- doctor can determine the best dose of mexiletine for you by measuring the
- amount in your blood. You may need periodic blood tests for this reason.
- If you miss a dose of this medication and remember within four hours (if
- you are taking it three times per day) or within six hours (if you are taking
- it two times per day), take the missed dose and then return to your regular
- dosing schedule. If more than that time has passed, do not take the missed
- dose; just return to your regular dosing schedule. Do not double the next
- dose.
-
- SIDE EFFECTS
-
- Minor.
-
- Abdominal pain, altered taste, changes in appetite, constipation,
- diarrhea, dizziness, dry skin, fatigue, fluid accumulation, headaches,
- heartburn, hiccups, hot flashes, light-headedness, nausea, nervousness,
- sleeping problems, slowed heart rate, sweating, vomiting, or weakness. These
- side effects should disappear as your body adjusts to the medication.
- You may experience constipation when taking this drug. To relieve
- constipation, increase the amount of fiber in your diet (fresh fruits and
- vegetables, salads, bran, and whole-grain breads), exercise, and drink more
- water (unless your doctor directs you to do otherwise).
- If you become dizzy, sit or lie down for a while; get up slowly from a
- sitting or reclining position, and be careful on stairs.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- black or tarry stools, chest pain, confusion, coordination difficulties,
- depression, difficult or painful urination, fainting, fever, hair loss,
- impotence, palpitations, psychological changes, rash, ringing in the ears,
- seizures, shortness of breath, speech difficulties, tingling or numbness in
- the hands or feet, trembling of the hands, or visual disturbances.
-
- INTERACTIONS
-
- Mexiletine interacts with several other types of medications:
- 1. Acetazolamide, sodium bicarbonate, or high doses of antacids can
- decrease the elimination of mexiletine from the body, which can increase the
- risks of side effects.
- 2. Cimetidine can increase the blood levels of mexiletine, which can
- increase the risks of side effects.
- 3. Phenytoin, rifampin, and phenobarbital can decrease the blood levels
- of mexiletine, which can decrease its effectiveness.
- Before starting mexiletine, BE SURE TO TELL YOUR DOCTOR about any
- medications you are currently taking, especially any of those listed above.
-
- WARNINGS
-
- * Tell your doctor about any unusual or allergic reactions you have had
- to any medications, especially to mexiletine.
- * Before taking mexiletine, tell your doctor if you now have or if you
- have ever had heart block, heart failure, liver disease, low blood pressure,
- or seizures.
- * If this drug makes you dizzy or light-headed, do not take part in any
- activity that requires alertness, such as driving a car.
- * Before having surgery or any other medical or dental treatment, be sure
- to tell your doctor or dentist that you are taking mexiletine.
- * Do not take any over-the-counter (nonprescription) asthma, allergy,
- sinus, cough, cold, or diet preparation without first checking with your
- pharmacist or doctor.
- * Do not stop taking this drug without first consulting your doctor.
- Stopping antiarrhythmics abruptly may cause a serious change in the activity
- of your heart. Your doctor may, therefore, want to reduce your dosage
- gradually.
- * Be sure to tell your doctor if you are pregnant. Although mexiletine
- appears to be safe in animals, studies in pregnant women have not been
- conducted. Also, tell your doctor if you are breast-feeding an infant. Small
- amounts of mexiletine pass into human breast milk.
