Hay fever medicine

Hi all!

I'm an airline pilot suffering from hay fever and therefor I require medicines. Unfortunately some medicines make me a little weary.
I just wanted to know if there are any pilots here using hay fever medicines which work for you?

In that way I can discuss with my doctor the proper medicin!

Thank you in advance.

For me Ceterezine or Loratidine work. Own brand daily hay fever tablets from any well known supermarket. If really bad, Beconase or similar.

For what it’s worth, cetirazine is on the FAAs unacceptable list because it is considered a sedating antihistamine.

Google away. The question was ‘what works for you?’ I’m not in FAA land so have no knowledge of that, my AME is happy as empirically it doesn’t make me sleepy. This from the NHS: ‘Cetirizine is known as a non-drowsy antihistamine. It's much less likely to make you feel sleepy than some other antihistamines.’.

I’ve always used Loratadine or Cetirizine. My AME also said Fexofenadine is fine (if it’s really bad) but in the U.K, you can only get it on prescription so I haven’t used it. The list of approved medicines is reviewed regularly and will also depend who your regulator is. Don’t ask on PPRuNe, ASK your AME and make sure you declare it on your medical each renewal.

Weirdly this year I’ve had no symptoms whatsoever. Either the grass pollen season is late or I’m magically cured! I’m just off to have my annual class 1 renewal and usually I’m a bit of a sniffling mess at this time of year.

Though I only reached the heights of a PPL, my AME was happy with Clarityn as it's non-drowsy

Am I reading it correctly where it says only occasional use and no flying for 5 half lives after last dose?

This class of drugs has half lives from 8 to 28 hours so that means 2 days to a week. If correct it basically grounds you during the high pollen season.....

The mean half life of Cetirizine is 8.3 or so hrs. So that’s presumably where the feds came up with the mandatory 48 hr wait. On the other hand, the non-sedating antihistamines are pretty much unrestricted if they are tolerated and not taken daily. The other thing they really want to make sure of is that the airman doesn’t have any issues with blocked eustacian tubes or sinuses that could cause an in-flight issue.

I generally suggest either Claritin or Allegra, (both OTC in the US) but there are certainly other options

I've had really good luck with Claritin - there is something that blooms around here in June that can knock me for a loop (the rest of the year isn't generally a problem).
I've not had any issues when using Claritin (and I'm fairly sensitive to that sort of thing in medications), although I'd try it on a couple of off-days before using it when you're going to be doing that pilot thing to see how it affects you.
