Does amoxicillin affect the effectiveness of antkyonceptive tablets?
Good morning, I use microgynon21, after taking today's tablet on the blister there are 3 tablets left. Today the doctor prescribed me Amotax, should I take a break for bleeding? If the last tablet will be taken in the middle of antibiotic therapy, will I be able to have sex without protection after the so-called period and the start of a new blister? Is it better not to take a break for bleeding and wait 7 days after antibiotic therapy?

Amoxicillin contained in Amotaks does not affect the effectiveness of contraceptive pills. You can use the contraceptive pill according to your schedule. There is no need for an additional method of contraception when using Amotaks. A review of 29 studies on the effects of antibiotics on antibiotic efficacy found that commonly used broad-spectrum antibiotics, which include amoxicillin, do not reduce the effectiveness of contraception. So far, the only group of antibiotics that has been proven to have a negative effect on the effectiveness of hormonal contraception have been antibiotics from the rifamycin group used to treat adenoma, e.g. rifampicin. This position is shared by the m.in who (World Health Organization) and the US government agency CDC.

To @anonim:
In the described situation, the absence of pregnancy symptoms and a negative pregnancy test result after a week indicate the absence of pregnancy. The spotting that occurred may be the result of hormone fluctuations caused by the interaction with the antibiotic, but also a natural result of hormonal contraception. If the test came out negative and there are no other worrying symptoms, there is no urgent need to see a doctor before the planned check-up.
Is the amoxcillin theory also confirmed when taking Slinda? I took amotax, during which I had intercourse once, about a week after stopping taking the antibiotic, 4 days of mild spotting occurred. I took a pregnancy test at that time, it came out negative. Is it possible that I did it too early and there was an interaction between drugs and I could be pregnant? I have no other symptoms, and the follow-up visit is in a month. Should I see a doctor earlier or is it unnecessary?
