The most common adverse reactions are nausea and vomiting.
This drug has a rather wide list of side effects, but they are quite rare. If you follow a special diet, do not drink alcohol and monitor the level of drug concentration in the blood plasma, then the danger is over.

Overdose is diagnosed in the case when the concentration of the active substance in the blood is more than 150 µg / ml.
Symptoms of intoxication include lethargy, depression, and the side effects listed above.
In case of intoxication, it is necessary to immediately clear the stomach by taking a couple of tablets of activated charcoal. The patient, as a rule, is sent to intensive care for procedures for cleansing the cardiovascular and respiratory systems of the body.
If the expectant mother will take Suksilep during pregnancy, then there is a chance of detecting malformations in the child. Constant monitoring of the state of the mother’s body is necessary.
If there is an urgent need, the medication should be administered in individual doses for the patient on certain days of pregnancy. The safest period of drug use during pregnancy is the period between the twentieth and the fortieth day.
