If a child has allergies, can we use a product similar to those used for adults?

. Hello, how long has your son been experiencing these symptoms and is this his first episode? Is he already taking any medication regularly? Does he have any known allergies to medications? Does he have any other health problems? Based on the symptoms you have described, I think it would be reasonable to try Claritin. The dose for children his age is 5mg to be taken once a day. Please check the package to ensure the correct dosage. You should also monitor the evolution of the symptoms, as an improvement should be visible in the first few days of taking it. If he has a fever, if his general condition worsens, or if he has breathing difficulties, please refer him back to a pharmacist or a doctor. Additionally, some non-pharmacological tips to reduce his symptoms would be to avoid going outside during windy periods, not to dry your clothes outside, and to keep your windows closed if possible to avoid the entry of allergens in your home.
