Currently, there are no FDA-approved medications, pills, or creams proven to safely and permanently increase breast size. While many over-the-counter herbal supplements claim to enhance breasts, they lack scientific evidence and can cause hormonal imbalances. Some prescription hormonal drugs, like birth control, may cause temporary breast swelling as a side effect, but they are not prescribed for this purpose. The only medically proven methods for breast enhancement are surgical options, such as breast implants or fat transfer. I highly recommend consulting with a board-certified plastic surgeon to safely discuss your options.
