Contraception
- Question
- Hello,
I (female, 18 years old) am currently taking colistin (inhalation) and co-trimoxazole (orally). I am now a bit confused as to the effects these two antibiotics may have on my contraception (NuvaRing®). Will the contraception still be fully effective, or less effective, or not at effective at all?
Furthermore, I just completed my i.v. therapy with tobramycin and ceftazidime two weeks ago; can that still have any influence?
Many thanks in advance and kind regards. - Answer
- Hello,
both antibiotics actually do not impact the effects of oral contraceptives and hence do not affect the contraceptive effect of the NuvaRing® (vaginal ring) either. Only very few antibiotics have been shown to influence the effect of the pill or similar contraceptives; these, however, you did not take. I hope I could help you with my answer.
Kind regards,
