Can I Start Tri-sprintec On Any Day?

Posted this as a reply by accident to another post. Here is my question:

I had my period last week from roughly Tuesday-Friday. I was just prescribed Tri-Sprintec today (the Wednesday after my period finished). I have taken it before in the past but didn't keep up with it.

I know that it says to start either the Sunday or the first day of my period so my OBGYN said to start it on my next period. Would I be ok to start it now? My main concern presently is not the birth control aspect, but getting used to the hormones ASAP for personal reasons.

Is there any harm to starting the pill on what is kind of an arbitrary start date and this much after my period? What might be the side effects? Also- in case it IS ok to start it whenever, when will I be protected (and this is the birth control part) from getting pregnant? Will it be after my next period?

Thanks so much.

No, there's not harm in it at all.

The reason they tell you to start on the first day of your menstrual cycle is because if you do that, then you are protected immediately from pregnancy.

So, what you need to know if you start it now is that you won't be protected until you have taken a full 7 days of the active pills, thus for that first week, you'll need to use some other form of contraception if you engage in sexual activity.

So, yes you can start whenever you want, but you will not be protected from pregnancy until the 8th day of taking them....and make sure you don't miss any pills or you'll basically need to start all over since you're new to taking them.

Are there any other questions or comments?

You should double check all information with your doctor to be certain, though. :-)
