Great question! The combination of trastuzumab (Herceptin) and pertuzumab (Perjeta) is available as an injectable form called Phesgo. Clinical trials have shown that the injectable version is just as safe and effective as the IV infusion — so no major differences in how well it works.
In terms of side effects, the safety profile is considered similar between the two methods. The big win with the injection is convenience — it takes just a few minutes compared to hours in an infusion center. Some MyBCTeam members have shared their experiences with Herceptin-based treatments, including side effects like:
- Whole body numbness, aching, and weakness
- Unusual sensations
- Heart-related concerns (regular heart monitoring is strongly recommended during treatment)
It's worth having a conversation with your oncology team about whether Phesgo is right for you. Your oncology nurse is also a fantastic resource for managing any side effects along the way — no suffering in silence! 💪
