Am I a candidate for breast augmentation if I am currently taking medication for bipolar disorder?

You should be able to continue with breast augmentation despite your medication. It is important to discuss all medication that you take including prescription, over the counter and supplements with your surgeon. This is for your safety. Your surgeon will advise any medications that need to be avoided prior to your procedure.

I don't have any knowledge that this is a contraindication to surgery, but it would likely be very straightforward to make a decision about this between your plastic surgeon and psychiatrist.
