For 2 days he has been using drugs Dulsevia and Neurotop Retard. I feel a very strong "spinning" when I close my eyes, as well as after opening them. Is this normal?

Dizziness is a common side effect of both Dulsevia and Neurotope Retard. In addition, the combined use of these drugs may enhance this effect. It is important to avoid, for example, driving a car or working with heavy equipment during increased "spinning". Adverse effects should disappear over time, but in very rare cases they may persist for a longer period of time. In each of these situations, it is worth meeting a doctor and reporting the occurrence of side effects: https://www.gdziepolek.pl/artykuly/jak-i-dlaczego-zglaszac-dzialania-niepozadane as well as consulting further treatment if it will cause discomfort in everyday functioning.
