Prednisone & late period?
2

I had about a week of a pretty high dosage of prednisone and 5 days of an antibiotic for a sinus infection and bad asthma flare up last month.
I finished all meds a little over 2 weeks ago.
I'm 9 days late. I took a pregnancy test when I was just a couple days late - not too worried (condoms) but had one in the house. Negative.
I've had some cramping and my breasts are very sore. I'm wondering PMS or should I take another test?
Does anyone know how common it is for prednisone or the antibiotic to cause this? I've had both of these before & don't remember the same thing happening.
Thanks.

Hello! I was on prednisone for a bad case of poison ivy and it delayed my period by 7 days. I called my doctor to see if predisone can cause that type of side affect and the answer was 'yes'. It's nasty stuff...I hope I never have to go on it again.

I hope that helps. Have a great day. :)

Hi there! I think just being sick or ill in general can delay your period. So, it's definitely possible. Try testing again in a few days if still no AF, but you should probably check with a doctor/pharmacist to see how common of a side effect that might be. Good luck! Hope everything works out like you hope! :)
