Special Instructions

Patients with moderate to severe dementia with Alzheimer’s disease usually have impaired ability to drive vehicles and operate complex machinery.

In addition, memantine may cause changes in reaction speed, so patients treated as outpatients should use extra caution when driving or operating machinery.
