DS13 severe hay-fever. Fexofenadine not working

[SplendidPendips]

DS13 is suffering from horrendous hay-fever, as he does every year. Horrendous blocked/runny nose that prevents him from sleeping is his worse symptom. But he also gets itcy eyes and it triggers asthma attacks. GP prescribed fexofenadine two years ago, he could only have the 60mg tablets the first year but since last year has been allowed 120mg. We make sure to start taking them before hay-fever season kicks off, take them daily, use nasal spray, shower every night and have an air purifier in his room. It's just not working. He's been up all night with horrible symptoms. What can we do? I am so so worried about gcses in a few years time. He can barely sleep or function.

DS has found sodium cromoglicate eye drops really effective (and nasal rinsing)

A smear of Vaseline under the nostrils helps too apparently

Such a shame for him, allergies are awful

I'd add nasal rinsing into his routine but also enquire about getting the allergy shots. The shots you'll likely have to go private for but have been a game changer for DD.

Just coming back to say thanks for the advice. I gave him an extra fexofenadine before bed for two nights in a row and that has helped (the nurse at the GP Surgery told us this would be OK for short periods, if desperate, when we saw her last year). Pollen count is supposed to be lower for the rest of the week so will go back to the normal dose until we see the GP. I have made a list of all the suggestions to talk through with him/her to see if we need to switch nasal spray etc.
