No: For a 2 yr old , you do't give any treatment must be seen by his pediatrician , for treatment.

Allergies: Has a doctor prescribed the claritin, singulair and nasonex (mometasone) for your 2 yr old child?? If so, discuss with your treating doctor. If not, stop immediately. These medications should only be used under careful medical attention for patients ages 2-6. Claritin is not cleared for under 6 unless under doctor's care. Absolutely no decongestant. Please do not risk your child's health, see your doctor.

Not advised: The FDA does not sanction it, but I think that you can do it.

Not recommended: Claritin-D relieves your allergy symptoms, including nasal congestion, but not for eyes. Always consult your pediatrician for OTC medicine given to children 2 years and under.
