How many Furaginum Teva pills per day can I take so that they do not reduce the effectiveness of Vines contraceptive pills?

To @Gabriela: No, the duration of therapy does not matter here.

And if I could do two weeks and I had to take 3 tablets every day, wouldn't they reduce the effectiveness due to the fact that it's so long

For @Gabriela: Without consulting a doctor, treatment can last up to 2 weeks. If after this time the symptoms do not go away, you should consult a doctor.

And for how long should you take the pills to work (I take 3 days but so far my bladder still hurts) and not to do it too long so that they do not affect the effectiveness of vines

To @Gabriela: You can continue Furaginum Teva therapy without any worries while using contraceptive pills, as we have already written about in other threads, e.g. https://www.gdziepolek.pl/opinie-i-pytania/74248/vines-co-moge-zastosowac-na-zapalenie-pecherza-jesli-biore-tabletki-antykoncepc https://www.gdziepolek.pl/opinie-i-pytania/74342/jaki-odstep-czasu-zachowac-pomiedzy-furagina-a-vines Yes, if you have 100 mg tablets, you should take 1 tablet 3 times a day.

So if I have tables of 100mg it means that I have to take one tablet 3 times a day. And whether I can use them for more than one day because I take them for 3 days and whether it will still not reduce the effectiveness of tablets

Furaginum Teva tablets taken according to the recommended dosage should not reduce the effectiveness of Vines contraceptive pills. According to the manufacturer's leaflet, it is recommended for adults to take 100 mg (2 tablets of 50 mg) 4 times a day on the first day. The following days (100 mg) (2 tablets of 50 mg) 3 times a day. Treatment should usually last 7-10 days.
