Can a delayed or no period be a side effect of Tabex?

I can't find information that products containing cytisine (such as Tabex) can induce menstrual disorders. Such an adverse reaction is not listed in the drug documentation. However, it cannot be completely excluded that such an action may have the stress associated with quitting smoking. In the case of prolonged absence of menstrual bleeding, pregnancy should be excluded (if you are sexually active). Long-term absence of a period is an indication for contact with a gynecologist. Since not all side effects can be known and recognized, it is worth reporting a suspected side effect: https://www.gdziepolek.pl/artykuly/jak-i-dlaczego-zglaszac-dzialania-niepozadane I enclose additional information: https://www.gdziepolek.pl/kategorie/rzucanie-palenia https://www.gdziepolek.pl/kategorie/leki-na-rzucanie-palenia
