From my understanding it’s the loratadine in the Claritin that makes it effective for the histamine response after Neulasta. Zyrtec has a different formulation. Anyway…thankfully the Claritin works…cheap and easy!

Honestly, that was the worst pain I had throughout my entire cancer odyssey…the bone pain after Neulasta. Fortunately it happened while I was in the hospital for a neutropenic fever. I woke up from a nap with this nagging back pain. Felt like I was in labor. 🤣 Those days were long gone!
I tried to dismiss it by moving around, lying in different positions. I’m a tough old bird but it became unbearable. Finally pushed the call button for the nurse. My favorite chemo nurse came in and figured it out! So she gave me a shot of morphine and then some Claritin. Phew… The morphine had my toes talking to me but worked until the Claritin kicked in. Then I took that for several more days.

Amazing what our bodies have gone through and recover from. ☺️
