-

- TREATMENT
-
- To decrease stomach irritation, you can take tocainide with a glass of
- milk or with food (unless your doctor directs you to do otherwise).
- Try to take the drug at the same time(s) every day. Tocainide works best
- when the amount of drug in your bloodstream is kept constant. This medication
- should, therefore, be taken at evenly spaced intervals day and night. For
- example, if you are to take tocainide three times per day, the doses should be
- spaced eight hours apart.
- Try not to miss any doses of tocainide. If you do miss a dose, take the
- missed dose as soon as possible. However, if the next scheduled dose is
- within four hours (if you are taking tocainide three times daily) or within
- six hours (if you are taking it twice daily), do not take the missed dose at
- all; just return to your regular dosing schedule. Do not double the next
- dose.

- should disappear as your body adjusts to this medication.
