Kidneys and liver
  • Xyzal (Levocetirizine) is processed by the kidney. If you have kidney problems, you may need a different dose to prevent increased risk for side effects. Don't use Xyzal (Levocetirizine) if you have end-stage renal disease or are on hemodialysis. Children ages 6 months to 11 years with kidney problems shouldn't use Xyzal (Levocetirizine).
Sleep
  • Can cause drowsiness.
  • Xyzal (Levocetirizine) can cause dizziness or drowsiness. Don't drink alcohol or take other allergy medications while on this.
  • Take at night to avoid potential sleepiness. Might affect my sleeping habits.
  • Doesn't really cause drowsiness, I had more drowsiness with Zyrtec than with this one! It actually helps my anaphylaxis even to the point that taking a pill at the beginning of an episode can cause the attack to stop progressing and diminish quickly after the medicine starts to kick in.
