Scarleteen

I was found to have a UTI and was given Nitrofuranton (100 mg) to treat it. I've been taking my birth control pills at the same time as the meds for the last week and in a few days I will have completed all the colored pills for the first pack of birth control


So i've read that this medication can interfear with birth control. Tomorrow night I will be taking my last dosage of it but when will my birth control be effective again? Do I have to wait a week (or more?) for it to be effective again? Where can I find information? I would like to go condomless . I've also taken the birth control each day at the same time or within a 4 hour window of missing the exact hour I take it each day,.

Edit: I'll be finishing my last dose on Sunday morning. Sorry.

Thanks

The best place to find information on this or any other drug interaction is the doctor who prescribed it or the pharmacy where you picked it up; you could give either place a call to check and see what they say about when your birth control will be back to full effectiveness. Using condoms, if that isn't something you're already doing, will give you enough added protection to make up for any lessened effectiveness your pill may have.

I cant.

I got looked at in the E.R so I cant contact them again.

As Mo said before, this is something that would be better answered by the person who prescribed the medicine. If you cannot contact them anymore, you can always either back up with condoms or avoid the kinds of sex that pose a risk of pregnancy until your pill becomes fully effective again. When does it become fully effective again is a question that, because we are not doctors, cannot answer for sure.
