When can I take off my steri strips? 4 weeks post breast lift/augmemtation.

I am 4 weeks post breast augmentation/breast lift. My doctor informed me my stitches should dissolve around the 3 week mark. All of my steri strips are still around my nipples - is it safe to take off the steri strips? Or should I wait until they fall off on their own? There's not much sign of them falling off on their own any time soon.
