Arrows on a birth control pill blister


Why do they put arrows on blisters of birth control pills even when all 21 pills in a blister are the same? I see a lot of people online are confused and think these pills are different and you have to take them following the arrows on a blister. The leaflets included with the pills often don’t specify that all the pills in a blister are exactly the same.


Hello @pig

I think it is just to help you check whether you have missed a pill. The arrows combined with the days of the week marked on the pill packets mean that you can check whether you have taken your pill that day.

Many thanks
