Does Antibiotics like Zrytec prevent Birth control from working???

Certain antibiotics can interact with birth control pills, making the birth control pills less effective and pregnancy more likely. Spotting - or ‘mid-cycle’ bleeding - may be the first sign that an antibiotic is interfering with the effectiveness of your birth control pills. \nAntibiotics that have been shown to interact with birth control pills include rifampin (brand name Rifadin), penicillin (Veetids), amoxicillin (Amoxil), ampicillin (Omnipen), cotrimoxazole (Septra or Bactrim), tetracycline (Sumycin), minocycline (Minocin), metronidazole (Flagyl), and nitrofurantoin (Macrobid or Macrodantin). \n\nTo help women avoid pregnancy while taking an antibiotic - and for at least one week afterward - doctors generally recommend they use a condom or spermicide as a back-up method of birth control. If you are taking both antibiotics and birth control pills, be sure to check with your doctor about how long you should continue to use a back-up method. Also, discuss any other questions you may have about this information. \n\nSources:\nDickey, R.P. Managing Contraceptive Pill Patients. EMIS Inc.,1998. \nHansten, P.D, J.R. Horn.

even on the pill and using condoms you can still get pregnant and std's (herpes, warts)\n\n(the pill does not start working for at least a month)

It sounds like you have a yeast infection which is often caused by your antibiotics throwing off the balance in your vagina.  Go to the grocery store and buy some Monistat.  It will give you relief in one day.

Your doctor should have told you that... but some birth control pills take up to a month to fully work! Talk to your doctor or a pharmacist!

I'd be very careful.  Meaning, I wouldn't rely 100% on the pill for BC.  I'd use some sort of back up just to be sure.  You could probably check one of the drugstore websites to see if it does or not.  \n\nAre you having any luck w/ the phentermine??  Is it helping you?  Just wondering if it worked or not.

lol..the only birth control that is 100% effective is castration and hysterectomies!\n\n:-)

Chlamydia is easily curable with antibiotics.  Yes you can get pregnant if you HAVE it or you've HAD it.\n\n:)

I take Marvelon. I was using another brand before but, switched. I've been on 'the pill' for over a year. I have not become pregnant and I do use it as my only form of birth control unless I've been on antibiotics. \n\nIf you are worried about the effectiveness of the pill, talk to your girlfriend, research and use condoms if you are still worried. There's nothing wrong with that. Good luck!

They shouldn't. Oral antibiotics only effect BCPs by making it harder for them to be absorbed in the stomach, therefore increasing chances of ovulation and spotting because the artificial hormones are not absorbed into the body. That's also why oral antibiotics don't effect BCs like the Patch or the Nuvaring. You can call your pharmacist and check if there is a drug interaction. There is also a drug interaction checker onlne but I don't know how good it is.

Registered Nurse here;  Hi:), well I just spent 10 minutes reading about this anti-fungal medication.  I wanted to make sure I was correct prior to posting, after reading the other answers, and especially the one from the pharmacy tech.  As I initially thought, this medication has absolutely no effect what so ever on birth control.  This medication treats candidacies (a yeast infection).  It is frequently given to all females with yeast infection.  Teenagers, Adults, non-pregnant and pregnant.  If you have any further questions or to verify this answer, call your pharmacist, make sure you speak with a pharmacist.\nThanks for the opportunity to address this most important and well worder question regarding your health, and the interaction of medications.

Antibiotics - Can kill the good bacteria allowing yeast to take over.  If your taking antibiotics eating yogurt can help.  \nClothing - Always wear lose fitting cotton underwear.\nChemicals - Douches and even some perfumed toilet papers are irritants.\nDiet - Some people feel that cutting down on foods that contain yeast helps lessen the intensity or frequency of yeast infections.  People with uncontrolled diabetes are more prone to infection. \nSexual Transmission - Yeast infections can be transmitted between people by direct contact.  \nHormones - Pregnant women are particularly prone to yeast infections. Many women taking contraceptive pills experience regular yeast infections as their hormone levels fluctuate.\nYeast infections are treated with antifungal drugs, such as clotrimazole or miconazole. There are creams and tablets used in the vagina, skin ointments, and pills. \n\nAntifungal drugs usually work well to treat a vaginal yeast infection. But infections that do not respond to treatment are becoming more common. Taking antifungal drugs when they are not needed can help make yeast resistant to the drugs. For this reason, you should not use antifungal drugs unless you are sure that you have a yeast infection. \n\nIf you are sure that you have a yeast infection, you can buy over-the-counter products to treat the infection. Be sure to follow the directions for using the product. If you are not sure whether you have a yeast infection or another type of infection or problem, you should see your health care provider. You should also see your health care provider if you have recurring yeast infections.

Absolutely!! Alcohol makes antibiotics neutral-meaning it counteracts their effectiveness. Gonna drink?  don't take the antibiotics-it's a waste of a good pill. Save it til the booze is out of your system.

depending on the type of infection the OTC may not work.  if you have insurance they should over the RX - the dr may have to call them for the authorization/override though!

Have you tried birth control pills? they are really helpful in regulating your cycles... Also, has your OB-GYN done all the needed tests? a sonogram, blood work, hormone levels...?

The pills do not work.\nPersonally, I have implants, and love them, but it wasn't a decision that I made on a whim or took lightly.  I made sure that I was all done having children, and researched it for over a year before I made my final decision.\nThis website really helped me in my decision making:  http://allaboutplasticsurgery.com/

No.  There is a blood-testes barrier that makes it really hard for antibiotics to penetrate the testis.  Semen levels of any drug are negligible.\n\nUrine, on the other hand, has significant breakdown products and some amount of the actual drug (in the case of Levaqin).  It has not been shown to be in significant enough amounts to kill vaginal bacteria and cause a Yeast infection.
