Cortisone with Birth Control
An_213750 posted:
I have been on birth control for about a year, and this week my doctor gave me a cortisone shot, supposedly to help my allergies. Will this interfere with my birth control?
Should I be worried to have protected sex after having this injection? How long will it stay in my system for?
PLEASE help!

If you don't have an answer for me, don't reply? Simple enough?

No need to get one is going to have your answer except the Dr who injected you.
Karen Luster, MD responded:

Medications that tend to decrease the potency of hormonal birth control are
· several seizure medications such as phenytoin and topiramate but not gabapentin, lamotrigine or levetiracetam.
· rifampin — this it the notorious antibiotic not the penicillin based or related ones
· And St. John's Wort.

Steroid injections are not on the list.
