For Allergic Rhinitis "This is the only allergy medicine I use after trying multiple ones. It works best for me without any side effects except very slight drowsiness. I also have an anxiety disorder, but this medicine doesn’t affect it at all, if anything, it helps. I take it as needed and sometimes daily if my allergies are bad or if my asthma kicks in. I’ve used it on and off for the last 7 years. My allergist recommended it and said it works the best for me after allergy skin tests."

For Allergic Rhinitis "My child cannot swallow pills, so the chewable Zyrtec is wonderful. Quick tip: to avoid drowsiness the next morning, take your dosage by early evening (don't wait until bedtime). By doing so, you'll get a comfortable night's sleep while breathing easily, too."

For Allergic Rhinitis "I'd rather suffer with the allergies than fight the sleepiness. My dr said it would not cause drowsiness, well, that's not so."

For Allergic Rhinitis "After a week using it, all symptoms were gone. If I miss it 3 to 5 days, symptoms returned. No drowsiness is the best part."
