1. What Memantine is and what it is used for

Dosage in patients with impaired kidney function
If you have impaired kidney function, your doctor will decide upon a dose that suits your condition. In this
case, monitoring of your kidney function should be performed by your doctor at specified intervals.
Method of administration
Memantine should be taken orally once a day. To benefit from your medicine you should take it regularly
every day at the same time of the day. The tablets should be swallowed with some water.
The tablets can be taken with or without food.
Duration of treatment
Continue to take Memantine as long as it is of benefit to you. Do not stop taking the tablets unless told to
do so by your doctor. If you stop taking this medicine, the benefits of your treatment will gradually fade
away. Your doctor should assess your treatment on a regular basis.
If you take more Memantine than you should
• In general, taking too much Memantine should not result in any harm to you. You may experience
increased symptoms as described in section 4. ”Possible side effects”.
• If you take a large overdose of Memantine, contact your doctor or get medical advice, as you may
need medical attention.
If you forget to take Memantine
Do not take a double dose to make up for a forgotten dose. If you find you have forgotten to take your
dose of Memantine, wait and take your next dose at the usual time.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.

How does Memantine work
Memantine belongs to a group of medicines known as anti-dementia medicines.
Memory loss in Alzheimer’s disease is due to a disturbance of message signals in the brain. The brain
contains so-called N-methyl-D-aspartate (NMDA)-receptors that are involved in transmitting nerve
signals important in learning and memory. Memantine belongs to a group of medicines called NMDAreceptor antagonists. Memantine acts on these NMDA-receptors improving the transmission of nerve
signals and the memory.
What is Memantine used for
Memantine is used for the treatment of patients with moderate to severe Alzheimer’s disease.
2. What you need to know before you take Memantine

In general, the observed side effects are mild to moderate.
However, Alzheimer’s disease in itself has been associated with depression, suicidal ideation and suicide.
These events have been also reported in patients treated with Memantine. You must tell your doctor
immediately if you notice that you are depressed or have thoughts about harming yourself.
Common side effects (may affect up to 1 in 10 people):
• Headache, sleepiness, constipation, elevated liver function tests, dizziness, balance disorders,
shortness of breath, high blood pressure and drug hypersensitivity
Uncommon side effects (may affect up to 1 in 100 people):
• Tiredness, fungal infections, confusion, hallucinations, vomiting, abnormal gait, heart failure and
venous blood clotting (thrombosis/thromboembolism)

Do not take Memantine
if you are allergic to memantine hydrochloride or any of the other ingredients of this medicine (listed
in section 6).

Very Rare side effects (may affect up to 1 in 10,000 people):
• Seizures

Warning and precautions
Talk to your doctor or pharmacist before taking Memantine:
if you have a history of epileptic seizures
if you have recently experienced a myocardial infarction (heart attack), or if you are suffering from
congestive heart failure or from an uncontrolled hypertension (high blood pressure).

If you get any side effects, talk to your doctor or pharmacist. This includes any side effects not listed in
this leaflet.

In these situations the treatment should be carefully supervised, and the clinical benefit of Memantine
reassessed by your doctor on a regular basis.
If you suffer from renal impairment (kidney problems), your doctor should closely monitor your kidney
function and if necessary adapt the memantine doses accordingly.
The use of medicinal products called amantadine (for the treatment of Parkinson’s disease), ketamine (a
substance generally used as an anaesthetic), dextromethorphan (generally used to treat cough) and other
NMDA-antagonists at the same time should be avoided.
You should inform your doctor if you have recently changed or intend to change your diet substantially
(e.g. from normal diet to strict vegetarian diet) or if you are suffering from states of renal tubulary
acidosis (RTA, an excess of acid-forming substances in the blood due to renal dysfunction (poor kidney
function)) or severe infections of the urinary tract (structure that carries urine), as your doctor may need
to adjust the dose of your medicine.
Children and adolescents
Memantine is not recommended for children and adolescents under the age of 18 years.

dantrolene, baclofen
