Although Metronidazole may weaken the effectiveness of tablets, this is a purely theoretical situation, so there is no reason to worry – especially since you are already using an implant at the same time.
Such a combination provides full control and metronidazole has no right to weaken it.

So in the case of a possible treatment - there are no concerns about the contraceptive continuity of the implant? Even despite the weakening of the protection from the pills? I continue to take Vibin Mini to make a milder transition to the implant and for the sake of a few days of travel (to prevent possible spotting). These were the recommendations of the gynaecologist after implantation.
