I was a nervous wreck and had a headache the day of. My blood pressure was 186/85. However, It all went very well. I was scheduled to be in the infusion room (very crowded) for one hour. The LPN got the needle in the vein very quickly with not much pain. She then ordered the zometa from the pharmacy. I am not sure what went wrong at that point but it did not come. She had to order again which extended my stay. I am not complaining because some people were there for two hours getting infusion. I do not think I had any side effects from the actual infusion but I did not feel well the next day (headache etc from the stress). I think I will be more relaxed next time (although it was not a great experience and I doubted my decision at times and wished I had taken Prolia instead). I am okay with it now. Time will tell. I guess it is possible to switch these osteo meds? Not sure though.
