2 months post herceptin

I’m about 2 month post herceptin and pertuzimab ((18 rounds)). I’m still experiencing a runny nose ( I know there are worse problems to have) but there are days when it’s just non stop and it’s so annoying! Just wondering if anyone else had this and how long after finishing treatment did it stop?
thanks Sadye 

Hello, It takes a while but in the meantime take an antihistamine. I took one or two everyday but I had aches and pains more often that a runny nose and it definitely helped with that.
