Allergic to Ativan after 30 days?

Patient: I have been taking Ativan for 1 month approx. I first started taking 0.5 mg then increased to 1mg 2 times a day then went back to 0.5 mg …I am now weening myself off of it and have noticed I am breaking out in rashes. could this be because I’m allergic to ativan or is it because I am weening myself off?

Symptoms: Rashes
