Please advize, I was prescribed Antenol for Mitral Valve Prolapse. I am in my first semester of pregnancy. The Cardiologist said it is 100 % safe to use but I have read up on medication and it is scheduled D which means there are definite risks associated with this medicine and the fetus. Should I rather not take it. My heartbeat is irregular. I would rather feel a bit strange and keep my unborn child from harm but is this the smartest thing to do. Please help?

Dear Lala

I presume you mean atenolol, which is a betablocker.
If the atenolol was prescribed because your heartbeat is a bit irregular, possibly due to mitral valve prolapse, then I would agree with you that you should not take it during pregnancy, or ever. Minor irregularities associated with mitral prolapse are almost always harmless, even if you find them uncomfortable, and often they do not respond to atenolol. In general I think you are quite right; it is a good policy to avoid any drug in pregnancy which is not absolutely essential.

When you stop atenolol, please do it gradually. Halve the dose for a few days and then halve it again for another few days before finally stopping.

I hope your pregnancy goes well.

Best wishes, JT
