What are some drugs that interfere with the effectiveness of oral birth-control, specifically Yaz?
I know antibiotics lower its effectiveness, but I recently heard that b-12 will, as well as St. John’s Wart, this got me wondering as I take various vitamins at different times, so do you know of any that are bad for the effectiveness of birth control pills, or where I could find that info? I looked on the Yaz website and couldn’t find much outside of how great it is for ya! Thanks!

P.S.-I’m married and just wanna put of kids for a few years, please don’t go off into a abstinence discussion! Thanks!
Oh, guess I should have specified that I’m already on it and have been for 5 months now, those symptoms are terrible, but I didn’t have any of that, my breasts were a little sore for the first 2 months, not bad tho, and I had a bigger tendency to get headaches for the 1st couple months as well, but nothing major and now I feel as if I’m back to normal, no major symptoms at all!

Answer by My Opinion: You ASKED for it!
According to the patient summary (I use YAZ too), it says:

“Drospirenon may increase potassium. Therefore, you should not take YAZ if you have Kindey, liver, or adrenal disease because this could cause serious heart or health problems.
Other drugs may increase potassium. If you are currently on a daily, long-term treatment for a chronic condition with any of the medications below, you should consult your health care provider about whether YAZ is right for you, and during the first month that you take YAZ, you should have a blood test to check your potassium level.
* NSAIDs (ibuprofen (motrin), naprosyn (aleve)…when taken long-term and daily for treatement of arthritus and other problems)
* Potassium-spraring diuretics (spironolactone)
* Potassium supplements
* ACE inhibitors (Capoten, Vasotec, Zestril)
* Angiotension-II receptor antagonists (Cozaar, Diovan, Avapro)
* Heparin
* Aldosteron antagonists”

Of course these listed drugs are in addition to the ones that are commonly known…antibiotics and yes, now Saint John’s Wort. I’ve never heard anything about B-12; its a necessary nutrient in the human diet. If you’re concerned, you might want to contact your pharmacist and consult them.

BE CAREFUL about taking Yaz – I wouldn’t recommend it. I took it for 2 1/2 months and suffered from nausea, diarrhea, lack of hunger, SEVERE mood swings, anxiety, depression, thoughts of suicide, breathing difficulties, DAILY migraines, sleeplessness….I could go on for days talking about how miserable I was. Seriously, it nearly destroyed my relationship AND my life. Don’t take it – the risks definitely outweigh the benefits. I stopped taking it mid-cycle because it was that bad! I almost lost my boyfriend because it was making me THAT crazy.
Find another BCP!!
