Allergic Rhinitis
"Started taking Singulair with Zyrtec 3 weeks ago for a severe allergy I developed to my 3 pet rabbits. No side effects to speak of (I did have a headache one day, but I don&#039;t think it&#039;s related) and today I held one of my bunnies for the first time in 6 months without allergy symptoms. Now I don&#039;t have to get rid of some beloved family members!"
