Does Trastuzumab Cause a Runny Nose?

Yes! I have been on Perjeta & Herceptin since December and one of my side effects is a runny nose. It gets worse when I am outside or in bright lights

Same thing happened to me while on the traz ! I was on it for one year. I’m happy to report that my nose eventually did stop running after treatment was complete.

Thank you both for your input 😊

My nose runs all the time and not in the same treatment 🤷‍♀️ maybe it’s related to all other meds we take ?

I have not been on this med but I did have the constant runny nose with another chemo med I was on, probably lasted about a month - good luck

I’m on the herceptin with taxol both weekly. My nose runs all the time but I was told it’s from the chemo and haven lost nasal hair.

Runny nose can be an unexpected side effect that some patients experience with various cancer treatments. It's thoughtful to reach out and ask others about their experiences, as fellow patients often have valuable insights about managing side effects. Consider mentioning this symptom to your healthcare team during your next appointment, as they can best assess whether it's related to your treatment and suggest appropriate management strategies.
