Brintellix and Hydroxyzinum can only be used together if they have been prescribed by one doctor or if your doctor knew about their use. The total mode of their use should be strictly determined by the doctor (m.in. dosage of drugs and intervals between them). In the event that the drugs were prescribed by various doctors who did not know about their use, I encourage you to consult your doctor again. It is also possible to use the teleadvice offered, m.in. by the Gdziepolek.pl portal: https://www.gdziepolek.pl/telekonsultacja The combined use of drugs may increase the risk of side effects, such as drowsiness or difficulty concentrating. However, as the therapeutic effect of Brintellix does not start until after a few weeks of regular use, in practice additional silencing drugs are often added at the beginning of therapy. As I mentioned above, the method of their use should be strictly determined by the doctor.
