dalteperin injection sites

I am a nurse and have a question about where Dalteparin can be given. I have researched most of the sites giving any info on the drug. Is it acceptable to give Dalteparin in the fatty area on the back of the arm? I am aware as long as its given subcutaneously and not intramuscularly but was wondering if there was any contr-indication to giving it in the fat on the back of the arm. Thank you.
