Did you try Claritin for the Neulasta injections? It works really well. Check with your oncologist first. But it was recommended to me by my oncologist and the staff in the infusion centers. Claritin - 24 hour capsules not the Claritin-D.
My instructions were to take capsule per day of the injection and then for at least 7 days in a row…same time each day.
It’s important to receive the neulasta because with chemo the body becomes seriously immune compromised with the reduction in blood counts. Neulasta will help jumpstart the production of neutrophils so that infection risk is lowered at a considerably faster rate than waiting for the WBC to recover on its own. If it’s ok with your oncologist, you might want to give the Claritin a try.

Neulasta is not just a patch; it is an injector (needle). I was given the choice of patch or shot, and also told many people preferred the shot because they couldn't always tell if the patch injector worked. I chose the shot. I also took Claritin the day before the shot, the day of and the day after. I never had any issues. Good luck.
