<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I am 29 years old and I took Zanocin 200mg for 4 days and half 9 tablets. Before this I did a pregnancy test and it was negative. I also went to a doctor and told me nothing about a pregnancy. After 4 days, while I was taking Zannocin I repeted the pregnancy test. And surprise: Pozitive. I went again to another doctor and he told me that I am pregnant in 5 weeks. My question: Could Zanocin affect my baby? Thank you very much .  <response>: HI, I understand your concern. You had taken Cancan . A short course. While you were in early weeks of pregnancy. No human tests are available for effect of Lanolin on fetus. . In animal studies a tenfold doze showed miner effects of skeletal development of fetuses. I feel you should stop taking avoid further use of medicine ask for a safer substitute to your doctor. Follow fetal development with USG scanning as advised by embryologist. Thanks.
