Hi, I had my first infusion of Ontruzant, the biosimilar of Herceptin on Friday and today I’ve got a very red sore rash on my back and inner arms. Just wondered if anyone has had similar side effects and how long they lasted. Thank you.

I saw my oncologist who has taken me off the new drug because its an allergic reaction and put me on Herceptin subcut injections after 10 yrs of Herceptin IV.
