If patients are taking any of these drugs, alternate therapy, dosage adjustment, and/or special test may be needed during the treatment.
- For missed doses, patients should be told to take the missed dose as soon as they remember. If it is almost time for the next dose, the missed dose should be skipped and the medicine taken at the next regularly schedule time. Patients should not take an extra dose to make up for the missed dose.
