It starts with an R. I haven't had any problems but if you are too worried just use condoms or another form of back- up.
Rifampin is the antibiotic you mean.
Anyway, the birth control vs antibiotic debate has been around for years. There are no studies that show that antibiotics affect the pill, but the medical community advises women that they MIGHT as a precaution. Recent studies are indicating that using both medications doesn't result in decreased birth control effeciancy, but no PROOF has been published.
Doxycycline is one of the antibiotics that has a precaution. Whether or not to be cautious is up to you. If you choose to take the safe route, you only need to abstain/use a back up method for 7 days after taking the last doxycycline tablet.
