From the side of the central nervous system: tremor, coma, ataxia, impaired consciousness.
From the gastrointestinal tract: nausea, vomiting, constipation or diarrhea, pancreatitis , hepatitis.
On the hematopoiesis side: neutropenia, thrombocytopenia, anemia, lowering of fibrinogen level, leukopenia, reduction of platelet aggregation.
On the part of the reproductive system: secondary amenorrhea , violation of the menstrual cycle.
Allergic reactions: itching, skin rash, erythema multiforme, photosensitivity, Stevens-Johnson syndrome.
Other: creatinemia, hyperammonemia, weight gain, hair loss.
Regular monitoring of transaminase activity, checking the level of bilirubin, amylase and blood platelets should be performed.
Valproic acid suppresses platelet aggregation, this increases the risk of increasing blood clotting during bleeding. It is necessary to take into account the complications associated with bleeding in the postoperative period in patients taking this medication.
In the case of prolonged use of Valparin XP, spontaneous bleeding and bruising may occur. It is necessary to immediately cancel the medication.

The drug enhances the effect of antidepressants, anticonvulsants and antipsychotics. Valparin XP differs from other anticonvulsants in that it does not affect the induction of hepatic enzymes. Due to this property, it does not reduce the effectiveness of oral contraceptives.
Joint taking of warfarin leads to its reduced binding to blood plasma proteins.
Sodium valproate affects the concentration of lamotrigine and phenytoin in the blood plasma.
Parallel reception of derivatives of acetylsalicylic acid and anticoagulants increases the antiaggregant effect.
Pregnancy and lactemia
