Hello, I have surgery planned for Thursday and my doc told me not to take anything that can thin my blood a week before it. My allergies are killing me and I need to take something for them. Would Chlorpheniramine maleate or Cetirizine HCL be okay to take?
Hi, There is no problem taking these antihistamines prior to surgery. Avoid taking aspirin or other anticoagulants. Ok and take care.
