  • I appreciate that Zyrtec works without making me tired. I wish I had found the generic version at Costco more quickly!

  • I have multiple allergies & Zyrtec keeps them under control year-round (along with Singulaire for food allergies & Flonase for pollen.) I like it because it doesn't make me woozy the way Claritin does. Best taken right before bed.

  • Take it at night. I found that it makes me slightly drowsy for 6-8 hours, so by taking it at night, I wake up without any drowsiness. The drowsiness is minimal for me, but noticeable

  • If you have been suffering with allergies for day , you may need to take Zyrtec for a few days, even though many say it works within the first day. It does if your just getting symptoms. It will work though.

  • Unsurprisingly, zyrtec dries you out, so expect to feel that in your mouth/nose. Hydrating will help. However, this was all worth it as it really did resolve my allergy symptoms (dramatically) within a couple of hours.

  • I took Zyrtec when the drug first came out by prescription. Overall the drug made me feel better than I had felt in years. I have read where Zyrtec makes people feel like zombies makes me feel alert and more energetic.
