Is it possible to combine Prokit, Helcid and Slinda? Do these drugs reduce the effectiveness of birth control pills?

If Prokit was taken only while taking placebo pills, it has no effect on the effectiveness of contraception.

Thank you very much for your reply 🙂 Will the use of Prokit while taking placebo pills not affect the effectiveness of hormonal contraception? All intercourse 7 days before taking placebo tablets and 7 days ahead will be protected if there was no additional protection in the form of a condom?

Additional protection should be used for the duration of the treatment and 7 days after its completion. It cannot be excluded that, despite the 3-hour interval, the absorption of the tablet will be disturbed.

So it is enough to protect yourself additionally throughout the treatment period with Prokit? You don't have to protect yourself for the next pack of "Slinda" birth control pills? If I have to take Helicid also before dinner, and I take it at 18.00 and I take Slinda at 21.00, will it affect the effectiveness and action of "Slinda"?
