Any medication has the potential to cause undesirable symptoms (“side effects”). In some cases, these symptoms may appear to include disequilibrium. It is not always straightforward to figure out whether the symptom of disequilibrium arises because of a specific medication; we discuss medication side effects elsewhere. When this question arises, undertaking a screening otovestibular workup is reasonable, and if this does not reveal a more convincing explanation, then it is reasonable to suspect the medication as the source of the symptom of disequilibrium, and the physician who prescribed that medication may consider reducing the dose, stopping it, or substituting it with another medication.
