For Allergic Rhinitis "I started taking Allegra D when I moved to North Carolina, where pollen is abundant. I began getting headaches that felt like migraines. I went to several sinus and allergy experts, even a neurologist. I had several C-scans and X-rays, but no doctor could find the problem. Recently, one sinus doctor did. It was an inflammation of the tissue lining in the sinuses. She told me to stop using Allegra D and gave me a prescription for a liquid steroid to mix with saline solution twice a day in a special plastic squeeze bottle with a curved nozzle. It has been a lifesaver. I will never take Allegra D again! Inflammation of the sinus tissue is mentioned as a rare side effect for Allegra D, but it should be stressed more."

For Allergic Rhinitis "This medication works great for allergies. My mom takes it, and she loves it. However, as soon as I take it, I start feeling all those crazy side effects: dizziness, nausea, pain everywhere, headaches, crying spells, etc. I personally won’t ever take it again because it is definitely NOT for me, but it is for people like my mom. So I don’t know. Maybe it just depends on your body because everyone is different."

For Allergic Rhinitis "Do NOT take this medicine. It should be illegal. I took it for 3 days, and all 3 days I felt nauseous, dizzy, unmotivated, and depressed. The worst part is I haven’t slept more than 2-3 hours a night. This medication will disrupt your life. I usually take Zyrtec D but decided to try Allegra out - my allergies have gotten exponentially worse on it. I have had severe sinus pressure, a cough, and headaches in addition to all the other symptoms."

For Allergic Rhinitis "So Allegra D seems to work on decongesting my sinuses, but this cough I got with it too is horrible. And the cough causes a headache. I'd rather be stuffed up than coughing with a headache."
