Do preparations for aphthous ulcers reduce the effectiveness of contraceptive pills?

The components contained in preparations for aphthous ulcers do not reduce the effectiveness of contraceptive pills, protection against pregnancy is preserved. We wrote about what drugs affect the effectiveness of contraception in the following article: https://www.gdziepolek.pl/artykuly/jakie-leki-oslabiaja-skutecznosc-antykoncepcji

So despite the fact that for a few days I use it for 3 times a day and each time I swallow a little bit of this preparation, nothing happens

To @Gabriela:

Efficacy remains preserved.

If I use canker sores dent max forte for several days and 3 times a day, if I always swallow a little of this product, because lubricating the wound always some amount is swallowed every time when lubricating, can it reduce the effectiveness?

For @Gabriela: Aftadent can be used for a period of 7-14 days.

And how many days can I use aphthadent for canker sores?

Even if swallowed a little?

For @Gabriela: AftaDent Max Forte does not reduce the effectiveness of Vines tablets. https://www.gdziepolek.pl/produkty/117891/aftadent-max-forte-zel-na-afty-zel/apteki

And won't AftaDent max forte also reduce the effectiveness of vines?

You can use Sachol with Vines tablets without fear.
