If the patient misses a dose, the dose can be taken when remembered. However, using too much ketotifen can cause an overdose, thus doses should not be taken too closely together or at the same time.

Patients and physicians should always communicate clearly about the use of daily medications, and patients should always inform physicians before making changes to daily medications.

These can all interact with medications such as ketotifen at various levels, depending on the dose and the patient’s medical history.
