[|Human|] Hi doctor, I was given ZinNat 250 mg tablets to treat bronchitis and I am also using Microgynon 30 combined pill. I am wondering if this antibiotics will affect the efficacy of Microgynon 30. I am quite worried as I have had sex recently. Please advice me on that! Thank you very much!
[|AI|]  Hello, Generally, taking antibiotics while taking oral contraception is safe. Only a few antibiotics mostly use in the treatment of tuberculosis (such as vitamin) can cause changes in the metabolism of oral contraception and reduce their effect. In your case, Final does not affect the metabolism of oral contraception and can be safely be used together. Make sure you eat a lot of plain yogurt and also take probiotics to keep your bowel flora healthy while you use antibiotics. I hope I have answered your query. Let me know if I can assist you further.
