I am taking omeprazole and my period is late what do I do?

I am 21 yrs old. I thought that I am the only one experiencing this since there is no study linking about delayed period effects from omeprazole. I have also digestive issues and take omeprazole for 2 weeks. I have always a regular period then, but after taking meds, my mens are very late and delayed up until now for 6 days. Researchers should take a look with this issue and make study.

Hi, I too had this issue, I am a healthy 19 year old young woman who has normal monthly cycles. Then I was put on omeprazole for stomach issues. I took my first month of dosage (directed by my doctor) and now I am late. I am not sexually active nor have I ever been. So this was concerning for me. I was a bit stressed the week I was supposed to start however it was not more than usual.

I am so relieved to see this on here! I thought I was going crazy. I am a healthy female who has had regular cycles for my entire life - like clockwork, every single 28 days. I do not take any medications but I took omeprazole for 14 days this last month. I am now 6 days late for my period and counting. This needs to be studied!

I’ve also been having irregular periods since starting omeprazole. I’m usually like clockwork. I can see a few mentions of this on online forums. It would be good to research this correlation further.

I also find my periods are late while on this medicine. I am 51 and have not started menopause yet. Nor could I be pregnant as my husband and I have taken precautions. I take the medicine as needed for EOE. When I am not taking it, my periods are like clock work. When I take it, I am significantly late and irregular. Sounds like more research is needed on this.

6 years later

I see this is 5 years ago, but I’m dealing with the same thing. 6 days late. Have had all the symptoms but no period. I’m about 95% sure it’s the medicine but can’t really find any info on this. I’ve only been on the medicine about 3 weeks.

Omeprazole doesn't appear to have known side effect, as to affecting your menstrual cycle. Could there be any other reason for your period being late?
