I’d ask at a pharmacy for the best medications.

Claratyne works for me and there is a child version for kids too.

My hubby always have Clarityne, it works for him.

I have been using Nasonex and the results vary.

I have been on allergy tablets for many years , on and off. You just need to be careful as you can get addicted ( like any drugs I guess ). Also I was advised to switch brands now and then eg Telfast, Zytec, Chemist brands etc.. so that you don’t get used to the one . In summer are the worst as get the itchy eyes . throat etc. Also stay away from pollen and vaccum your house regulary to get rid of dust .

NAsonex is good but you need to use it continually to build up your resistance.
