Hi Percy,  
I’m Rachel- Lead Nurse here at Anthony Nolan. Apologies not to reply to this sooner, I assume you have spoken to the hospital team and received clarification on your query now but I wanted to reassure you that the GCSF/Lenograstim injections would not have any interactions with the listed medications you already take.

Its likely you have completed the course of injections and given your stem cell donation by now- it’s an amazing thing you have done, thank you! I hope you are feeling OK following the GCSF injections and donation, please do get in touch again if you need any further advice.  
Kind regards  
Rachel
