For Allergic Rhinitis "First symptoms were congestion in my nose and vertigo from fluid in my ears. After a visit to an ENT, I was told to take Claritin and Flonase along with Azelastine. Worked wonders for my congestion but started to feel really foggy in my head. Back to the ENT and had a hard time describing my symptoms other than being 'off.' This brought on anxiety, did not want to drive, or leave the house. Never felt like this before. After reading the comments on here, I stopped all medication and felt better less than 48 hours after. Not 100% but headed in the right direction. Anyone else feel this way?"

For Allergic Rhinitis "I took this for some time and never realized until coming here and reading reviews that it could be responsible for my racing heart, palpitations, brain fog, and on top of all that, it didn't work well at all."

For Allergic Rhinitis "Honestly, I am very sensitive to medications, so I should have felt some sort of relief, and I felt nothing but side effects. Dizziness, fog brain, and overall, it made my head feel strange. I will be discontinuing this medicine and trying something else."

For Allergic Rhinitis "This stuff did very little for my allergies. It made me feel tired and spaced out and gave me minor heart palpitations. Benadryl works much better but has some dangers if taken long term. Nasacort has few side effects for me but only limited help. Some homeopathic nasal sprays work better than most OTC stuff."
