Is it possible to combine Amantadine with Biomentin, or is it better to set aside for a week?

The above medicinal substances mentioned in the question - Amantadine and Memantine are prescription-only drugs, so the legitimacy and need for their combined use in therapy is assessed by the doctor. Do not use these preparations without consulting a doctor. Amantadine and Memantine belong to the group of NMDA antagonists. Their parallel use should be avoided, as they act on the same receptor system, which may increase the incidence and severity of side effects (mainly from the CNS). In this case, there is a risk of developing pharmacotoxic psychosis. Discontinuation of Biomentin is also not a solution, since the drug lasts quite a long time in the body - the half-life is 60-100 hours, this means that the drug will be completely removed from the body after 5-8.3 days. In this case, I encourage you to consult the attending physician, who will recommend the appropriate therapeutic treatment for the patient.
