Special instructions

Prescribed with caution for epilepsy and patients with thyrotoxicosis. The optimal dose is achieved gradually, with weekly increases.

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

In addition, memantine may cause a change in the reaction rate, so patients receiving treatment on an outpatient basis should take special care when driving or operating machinery.

From the body as a whole – common adverse reactions

Often Headache

Rarely Fatigue

Infections Rare Fungal infections

Mental disorders Often Drowsiness

Rare: Confusion

Rarely Hallucinations

Frequency not set

Psychotic reactions

Cardiovascular system disorders

Rarely Hypertension

Rare: Venous thrombosis/thromboembolism

Gastrointestinal disorders Common Constipation

Rarely Nausea, vomiting

Frequency not established Pancreatitis

Disorders of the central and peripheral nervous system

Often Dizziness

Rare Gait disturbance

Very rare Convulsions

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

There are isolated reports of the occurrence of these adverse reactions when using the drug in clinical practice (data obtained after the drug was marketed).

Interaction

When used simultaneously with L-dopa drugs, dopamine agonists, and anticholinergics, the effect of the latter may be enhanced.

When used simultaneously with barbiturates and neuroleptics, the effect of the latter may decrease.

When used together, it may change (increase or decrease) the effect of dantrolene or baclofen, so the doses of the drugs should be selected individually. Concomitant use with amantadine, ketamine and dexamethophan should be avoided.

Plasma levels of cimetidine, procainamide, kinidine, kinin and nicotine may increase when taken simultaneously with memantine. It is possible to reduce the level of hydrochlorothiazide when taken simultaneously with memantine.

Overdose

Symptoms: increased severity of side effects.

Treatment: gastric lavage, taking activated carbon, symptomatic therapy.
