Copying this from Meso as well, there was a good post a few years ago. Posted by Fraggle:
5) Histamine reaction
This doesn't occur as often, but is still a potential possibility. For a compound to become biologically active the ester must be cleaved from the parent molecule. This results in the formation of a carboxylic acid. Some people find that they are sensitive to one of these. This results in swelling, warmth, redness and possibly a rash at the injection site. In the worst instance the individual may have an existing allergy to the carrier oil (sessame, etc...) that can result in anaphylaxis (swelling and occlusion of the airway) in addition to localised inflammation. If any histamine reaction results, immediately discontinue use and switch to an alternate carrier oil and/or alternate ester. If anaphylaxis results, immediately seek medical attention.
