No. It does not. Nor will it ever. That is a complete myth. The only ones you need to worry about, are ones like Fresca which contain REAL grapefruit juice. Grapefruit is known to interact with many drugs, including Birth Control. Grapefruit slows down your body's ability to eliminate the estrogen from your pills which leaves it circulating in your system longer which then greatly increases all of the risks that birth control carries. You can still drink it, (I do) but sparingly and not often.
There are no known drug interactions between ketorolac (toradol) and combined or progestin-only birth control pills.
No Singulair (montelukast) has no effect on birth control pill. It can be taken at the same moment (or in the same day) regularly.
antibiotics are one of the most common medicines that counter the effects of birth control. there could be others. you should speak to your doctor.
No, x-rays do not lower the effectiveness of birth control pills. However, if you experience any vomiting or diarrhea following an x-ray, it could potentially interfere with the absorption of the pill and reduce its effectiveness. It is advisable to use additional contraception in such cases.
While a few antibiotics can reduce the effectiveness of birth control pills, they don't have any significant effect on whether or not you get pregnant if you are not on the pill.
I have also wondered this question and with the research that I have done, it says that neither affects the effectiveness of birth control pills
It is known to reduce the effect of birth control pills
Yes, normally birth control pills will reduce the number of days of bleeding.
If your birth control pills give you a "sugar pill" for the last week of your cycle, it is OK to skip them, assuming you start back up after the right amount of days, usually after your period has come. However, not all birth control pills have sugar pills for those days. Some just have a lower dose pill, and skipping them could reduce the effectiveness.
Fluconazole 150mg can reduce the efficiency of hormonal birth control pills. You should speak with you doctor to find out whether you should practice an alternate method of birth control.
Antibiotics will completely eliminate the usefulness of a birth control pill. A secondary source, such as condoms, should be used while on antibiotics to continue the prevention of pregnancy. Usually the medical information on the birth control package states which medicines will interfere with the product.
Taking more than the prescribed amount of birth control pills doesn't increase effectiveness, but does increase cost and the risk of side effects.
