Loratadine 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?"

Loratadine 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."

Loratadine 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 "I purchased Claritin NON-DROWSY (yeah right) this morning. I took one at 10 am, and within an hour, my symptoms all stopped. I felt exhausted and spaced out, and by 4 pm, I started to feel like I was on speed and wired. I felt like I was in slow motion, saying, 'What the heck is going on with this?' It’s nearly midnight as I’m typing this, and I feel tired but wired. I can’t wait till morning, being it’s a 24-hour dose for this to leave my body, but it did stop my coughing, all day wheezing, sniffling, and sneezing, but these side effects are not worth it. Anyone have any recommendations for another allergy med, as I can’t take a decongestant due to the ingredient causing worse fatigue."

Loratadine 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."

For Allergic Rhinitis "This drug is very useful because it works well without any dizziness/fogginess. Works well with my eye allergies."
