I don't think the allergy medicines could affect it, and I don't really think the viactiv (that's just calcium, right?) would at all.

However, it's never difficult to give a quick call to the pharmacist.... I always check when I want to take something.

no only antibiotics will interact with birthcontroll ..i know this because i work at a pharmacyy so dont worry u can take anything as long as its not antibiotics and u will be fine

I don't think that's true-

antibiotics, steroids, St. John's wort, anticonvulsants, (as well as those used for mental health purposes) can all have effects. And certain painkillers (tylenol) can be less effective on certain types of birth control.

Like I said, you're probably fine but it never hurts to call a doc.

I have a friend in her third year of pharmacy school who also works as a pharmacy tech and she looks these things up in a database for me. You should always check to be sure. It is not just antibiotics.

Okay, thanks for the info! I'm pretty sure I asked the Planned Parenthood person about Benedryl and Advil when I first went on the pill, and I think she said it was fine...it was just a while ago now, and my memories of that day and what specifically we talked about are a little fuzzy...

I think you are right...it is probably fine...but I think I will follow your advice and put a call in anyway...

Thanks again!

Just to clear something up for anyone finding this page from a search or something... I had to call my pharmacist and ask because I couldn't find anything online. Barbituate anticonvulsants interfere with birth control, but benzodiazepines (i.e. klonopin, xanax) do not.

Thanks for the info...
