Information for Patients
To help avoid stomach upset, it is recommended that the drug be taken after meals.
If a single daily dose is prescribed, it may be preferable to take it in the morning to minimize the effect of
increased frequency of urination on nighttime sleep.
If a dose is missed, the patient should not take more than the prescribed dose at the next dosing interval.
