<s>[INST] I am on Lisinopril. I was just wondering if it can cause infertility. My husband and I have been trying to conceive for six months now and still have not been able to get pregnant. I was able to conceive quick with our first child- before I was put on Lisinopril. [/INST] Hello, Lisinopril can lead to weight gain and this, in turn, can decrease fertility. Your primary condition for which Lisinopril was started also may cause infertility. If you become pregnant, you will have to change over from Lisinopril as there is a risk of teratogenicity. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Noble Zachariah, Internal Medicine Specialist </s>
