- TREATMENT
-

- for a recommendation.
- Try to take disopyramide at the same time(s) each day. This medication
- works best if the amount of the drug in your bloodstream is kept at a constant
- level. It is best, therefore, to take this medication at evenly spaced
- intervals day and night. For example, if you are to take it three times per
- day, the doses should be spaced eight hours apart.
- Try not to miss any doses of this medication. If you do miss a dose and
- remember within two hours, take the missed dose as soon as possible. If more
- than two hours have passed, do not take the missed dose; just wait for your
- next scheduled dose. Do not double the next dose.

- atenolol, betaxolol, carteolol, esmolol, labetalol, metoprolol, nadolol,
- penbutolol, pindolol, propranolol, and timolol) can have additive negative
