How Does Cetirizine Work for Dizziness

Hi

I saw the posts on using Cetirizine for dizziness. I always keep some in the house as I have allergies and I’ve been taking it for the last few days, 10mg twice a day. I did try taking 20mg all at once but found it made me feel rather unwell. Its certainly improved some of my symptoms, less brain fog and fatigue. Im still unbalanced but its not as noticeable.

I’m curious about why it helps and is it useful in helping diagnose what is causing my symptoms, ie MAV or PPPD or something else. I’ve seen you should stop after 2 weeks. Again I just wondered why? Thanks.

Good that it is helpful!

Hi
Yes sorry about the spelling. I’m none the clearer though lol.I’m very familiar with numerous antihistamines. I’ve tried Fexafenadine in both UK strengths and I get Promethazine on prescription to help with insomnia.

And when my imbalance started, because that’s the primary symptom for me, I’ve never had dizziness in the sense of spinning or nausea. My other half had a bout of Labrynthitis a few years ago and was pretty much incapacitated by it., I can function but feel off balance, especially when I walk or move my head. Almost like being drunk (except I’m teetotal). I got Betahistine prescribed but that did nothing for me.

So in a very long winded way I guess I’m asking is why would this particular antihistamine help with the imbalance. Unless its linked to excess histamine in the body. And would other antihistamines work as well? Or does it work on the vestibular system in some way?

I’d be delighted to hear if it does. I found imbalance one of the last symptoms to go and it went all by itself whilst I was not on medication.

I’ll be very surprised if anyone can tell you why it works, but perhaps it helps even out the pressures between the middle ears?

I’m not sure even the doctors know how these meds work, they just note a positive response when they observe one, leading to the recommendations we have.

Hi

I seen antihistamines used for Eustachian tube dysfunction and I’ve often wondered if thats what I’ve got. I get the popping and clicking in my ears and brief, intermittent ear pain. When I do the Valsalva manouvre one ear will pop but not always the other. I’ve had the weird sensation of hearing my own voice in my ears recently. I didnt know if ETD could cause balance issues though.

Can’t help with the why but my vestibular rehab physio has suggested I take antihistamines with me when I travel in a few weeks to help with any possible acute symptoms. It’s obviously a thing, but I have no idea why!

Alternobaric vertigo it’s called. But then exactly the same symptoms can have a diagnosis of Secondary Hydrops too. It’s hardly ever certain.

My endo prescribed cetirizine and famotidine for MCAS (mast cell activation syndrome). Together they block both channels. Vertigo is among the symptoms of MCAS, so it must have to do with excess histamine and inflammation in the body. Once this is calmed down, you feel better. Cetirizine must just work for you.
