Concomitant use with barbiturates, neuroleptics may decrease their effect.

Concomitant use may change (increase or decrease) the effect of dantrolene or baclofen; therefore the doses of the drugs should be adjusted individually. Concomitant administration with amantadine, ketamine and dexamethorphan should be avoided.

With caution is prescribed in epilepsy, patients with thyrotoxicosis. The optimal dose is reached gradually, with weekly increases.

In patients with Alzheimer’s disease at the stage of moderate to severe dementia the ability to drive vehicles and operate complex mechanisms is usually impaired.

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

Contraindications

With caution:

Side effects

Adverse reactions are classified according to clinical manifestations (according to the involvement of certain organ systems) and by frequency of occurrence:

In the body as a whole – general adverse reactions

/p>

Hallucinations have been observed mainly in patients with Alzheimer’s disease at the stage of severe dementia.

There have been anecdotal reports of these adverse reactions when the drug is used in clinical practice (data obtained after the drug was commercially available).
