Since levetiracetam is eliminated by the kidneys when prescribing elderly patients and patients with renal insufficiency dose should be adjusted depending on the value of QC.

QC can be calculated based on the concentration of serum creatinine, according to the following formula.

QC (ml / min) = [140-age (years)] &№215; body weight (kg) / 72 &№215; serum creatinine (mg / dL)

received value x 0.85

* - on the first day of treatment with Keppra^® 750 mg saturating dose is recommended.

** - after dialysis, an additional dose of 250-500 mg is recommended.

dose adjustment of levetiracetam should be made taking into account the degree of renal failure, using the recommendations given for adults.

impaired liver function mild to moderate severity correction of the dosing regimen is not required. Have patients with decompensated liver dysfunction and renal failure the value of QC may not reflect the true degree of renal dysfunction, therefore, when QC <70 ml / min It is recommended to reduce the daily dose by 50%.

Pills should be taken orally, drinking plenty of liquid, regardless of the meal.

Dosing solution carried out using a measuring syringe with a nominal capacity of 10 ml (corresponds to 1 g of levetiracetam) and with a dividing price of 25 mg (corresponding to 0.25 ml) supplied with the product. A measured dose of the drug is diluted in a glass of water (200 ml).

To dispense the solution using a measuring syringe, open the bottle: to do this, press the cap and turn it counterclockwise. Insert the syringe adapter into the neck of the bottle, then take the syringe and place it into the adapter. Turn the bottle upside down. Fill the syringe with a small amount of solution by pulling the plunger down, then push the plunger up to remove air bubbles. Pulling the plunger, fill the syringe with a solution before dividing, corresponding to the amount of ml of solution prescribed by the doctor. Pull the syringe out of the adapter. Enter the contents of the syringe into a glass of water, pushing the piston until it stops. You should drink all the contents of the glass. Then rinse the syringe with water and close the bottle with a plastic cap.

Physiological changes in the body of a woman during pregnancy can affect the plasma concentration of levetiracetam, as well as other antiepileptic drugs. During pregnancy, a decrease in plasma concentration of levetiracetam was observed. This decrease is more pronounced in the first trimester (up to 60% of the baseline concentration in the period before pregnancy).

Treatment with levetiracetam pregnant should be carried out under special control. It should be borne in mind that interruptions in antiepileptic therapy may worsen the course of the disease, which is harmful for both the mother and the fetus.

In connection with the reported cases of suicide, suicidal intent and attempted suicide in the treatment with levetiracetam, patients should be warned about the need to immediately inform their doctor about any symptoms of depression or suicidal intentions.

Influence on ability to drive motor transport and control mechanisms

Effect of Keppra^® on the ability to drive vehicles and control mechanisms has not been specifically studied. However, due to the varying individual sensitivity to the drug on the part of the central nervous system during the period of treatment, it is necessary to refrain from driving vehicles and practicing potentially hazardous activities that require high concentration of attention and quickness of psychomotor reactions.
