i was in the er in the beginning of the second week of august for treatment of a bad bacterial infection and they gave me iv rocephin there and 10 days worth of 2000mg of keflex to take. my period, which I had just gotten, lasted another 2 and a half weeks (until the 1st of sept), albeit I was spotting the last 2 weeks of it and its generally light anyways bec. of the iud.
just wondering if anyone knows if either of those 2 drugs could interfere with the effectiveness of mirena.
