If you are taking this medication once a day and miss a dose, take it as soon as you remember. If you don't remember until the next day, skip the missed dose. Do not double the dose to catch up.

If you are taking this medication twice a day and miss a dose, take it as soon as you remember. If you have missed the morning dose and it is near the time of the evening dose, you may take both doses together. If you miss the evening dose, take it as soon as you remember only if you remember on the same evening.

If you are taking this medication 3 times a day (about 8 hours apart) and miss a dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up.

On the following day, continue with the regular once, twice, or three-times-daily schedule as directed by the doctor.
