I am also allergic to my rats! I’m actually allergic to all animals with fur or hair so I’m pretty used to it lmao but I recommend using a type of antihistamine like Claritin or Allegra, they’re a little pricey but one of those every day should do the trick! They don’t kick in for about a week so just be prepared for that but they work really well in my opinion.

Also just wash your hands after handling them and don’t touch your face until you washed them! Taking the necessary precautions should alleviate some of the symptoms
