Greetings all!

My 14 yr old female aussie suddenly got very woozy last night, has had trouble walking with confidence, and has thrown up thrice last night and this morning. My guess is that this is geriatric vestibular disorder. She did something like this...vertigo-like symptoms plus nausea...a few weeks ago, but that time it only last a number of hours. She is drinking water okay, and is not in any pain that I can detect. Resting comfortably at my feet at present.

It is Sunday now, and I plan to take her to the vet tomorrow (Monday), but I do happen to have some Bonine/meclizine in the house that I see is often recommended for this kind of disorder (or for car sicknness). It expired in 2015, but I doubt that would make much difference to its potency. Any thoughts/experiences re the administation of this otc medication? I saw a recommendation online of 25mg/day...does that sound about right for a 50 lb dog?

Thanks!

I wouldn't give any meds to an undiagnosed dog, look up the possible side effects of each medication. If she ends up diagnosed with one of the side effect, then it could exacerbate the situation.

I second not giving her meds, until you check with your Vet. I do know that meclizine at least in humans will cause extreme drowsiness, and I don't know if its even safe for dogs.

Does indeed sound like a typical case of vestibular syndrome (called such because it has no known cause). As for Meclizine usage, I have never had it help but it also is very unlikely to cause any harm. The correct dosage is vague, though, and often is listed as 1/2 to 2 tablets 2x a day (but leaves the weight of the patient out, which makes it a pretty broad dosage). One source lists a more accurate dosage, but also admits there is no research backing it up.

For vomiting due to vestibular disease, a drug like Cerenia is far more effective than is Meclizine anyway (but it is not over the counter- needs a script). Nothing I know of seems to help the dizziness, but in 95% of all cases, it resolves on its own (the other 5% may be caused by something like a brain tumor, infection etc.- SOMETHING that is never discovered in the majority of cases... which could explain why those few dogs do not improve). Time for resolution varies a lot from dog to dog, some improved in just a half hour while others take weeks to be able to stand up again.
