Egg allergy and botox/Azzalure. Is there a risk?

I have an egg allergy and have been prescribed an adrenalin pen 6 months ago after a nasty reaction to egg. Ihad always eaten eggs but developed this allergy 5 years ago which has gradually got worse. I had botox 1 year ago and was fine loved the results but am now nervous to have it again as lots of sites say not to if you have an egg allergy. There is so much conflicting information should I avoid azzalure and Botox ?
