Query: INEFFECTIVE

I purchased this for a 10 year old with hay fever allergies.We tried the package recommendation of half of the adult dosage with no success. Not even the adult dosage helped the super itchy watery eyes and runny nose. After talking to a pharmacist, I ended up getting Zirtec and it worked!I am a big fan of natural remedies (herbal, homeopathic, etc.), but this one was a huge disappointment.
