For Allergic Rhinitis "This is the 2nd time in a month that I have suffered from dizziness and fatigue after taking Claritin. My blood pressure has dropped to 96/58, which is low even for me. I have always had lower than normal blood pressure. I last took Claritin on Thursday morning, and this is Monday, and I can finally stand up without feeling dizzy."

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 took Claritin for congestion due to allergies. Day 1, I felt a bit tired after taking it, but the congestion began to clear. Day 2, I felt fine for a few hours with the exception of dry mouth, all of a sudden, I became severely dizzy and felt like I was going to fall out of my chair. Checked all my vitals: BP, oxygen, sugar, etc., and they are perfect. The only new medicine I took was Claritin. I am lying on my back right now, writing this review while I am recovering from the effects."

"I ran out of Zyrtec and did not have a lot of money, so I opted for 2 one-packs of Claritin non-drowsy 24 hr. I have severe anxiety and moderate depression that I’ve been regulating on my own for the past 3 years. So the first night I took it, and the next day I could barely get out of bed without feeling nauseous and dizzy. I also noticed that my anxiety in the car was heightened, and I almost had to pull over because I felt so sick. I didn’t take the pill the next day, and within the next day my anxiety went away. This morning my allergies were so bad I took the 2nd pill knowing what could happen, and I’m dealing with the worst anxiety I think I’ve ever had. I couldn't get into the car without feeling like I was going to pass out. So ultimately I will not be taking Claritin anymore because, like others have reviewed also, it affected them mentally and caused anxiety and a weird head feeling. Also, it did nothing for my allergies compared to my Zyrtec."
