Can Roswera be taken together with Depakine and Velaxin?

Yes, you can. There are no contraindications to the simultaneous use of Roswery together with Depakine and Velaxin.

According to the current medical literature, in some cases, the simultaneous use of Depakine and Velaxin may cause excessive sedation, impaired consciousness, drowsiness, and difficulty performing the intended movements. In the case of such a combination, you should also avoid driving or performing other activities that require increased psychomotor activity. The combination of these medicinal products may be therapeutically beneficial, and the patient should be closely monitored for any symptoms of concern during the combination of treatment.
