312 Libre

Well we had quite a night. I gave a very small increase yesterday at breakfast and last night she dove (on the Libre). It stopped reading for 2 hours then it shut down (as it was reading in the LO range
It was a new Libre which I installed the day before (since she somehow got her prior one to be unattached, my little wizard)

Sooo at midnight last night I heard the dreaded sound that the Libre had failed. By 12:30 am a new one was installed and scanned, giving data by 1:30 am.

I ear pricked her before the install and she was 166 on the Contour meter (but Libre earlier read her as LO).

Need her to be in decent numbers but not so low she shuts down the darned sensors.

We are at day 5 or her last B12 shot, next shot due on Thursday. Hoping she stays steady until Thursday.

Question about Cereina...I am currently giving her 16 mg daily (since July when her GI episode began). When I search our site (FDMB) there seems to be conflicting information on dosing.
Maybe she doesn't need such a large dose???

I see 1 mg/lb and I see 1mg/kg in various posts here

She is about 14.5 lbs (6.6 kg) at this time,

Based on 1 mg/kg that would be around 12 mg dose daily (Vetlens.com)
Cerenia for Cats: Dosage, Uses & Side Effects (2026 Guide)
or (Innovet.com) says about 1/2 of 16 mg pill (8 mg)
Cerenia for Cats: How to Use and When It Won’t Help

2 references with different dose information

Any thoughts?

I am going to stop her Ondansetron today as I don't "think" she is nauseated. She's eating great (I started it last Wednesday when she had a GI bout again a day before her B12 shot was due last Thursday. Paws crossed and anti jinx).

Keeping Mirataz in place (every time I get rid of that all hell breaks loose with her bowels).

Hope you are all having a calm day!


Waiting for dinner

Hi Staci, so glad Ivy is eating well! I am sorry you lost two sensors the last few days. This must be so frustrating! I just looked up how much Cerenia I gave to Binie. She was a little bit heavier than Ivy (around 7 kg) and the vet prescribed 8 mg daily. We also had the 16 mg tablets, so half a tablet. I checked on the German websites and they all say 1mg/kg, so 8 mg was even slightly overdosed. I hope you get some further insights. I learned over time that the American recommendations sometimes vary and usually they seem to give bigger doses with some meds. Good luck with the new libre!

 

[Connie & Parker & Moonie]

That sounds like a tough evening Staci - I’m sorry that you lost two Libres in such a short span of time. Hopefully you’ll get some good advice - I’m thrilled that Ivy seems to be doing much better and may be able to come off or dial back on some of these meds soon

Ivy looks beautiful and very impatient for dinner in that photo!

Thank you Heike! I had a feeling it may be that kind of dosing. I am not sure how I ended up giving 16 mg. Of course now since she's so shaky I am afraid to change anything (like halve her dose) right before the end of her B12 cycle. She's due for the next shot on Thursday.

So 1 mg/lb (would be around 14-15 mg of Cerenia/mariopant pill) correct??? (would then be the 16 mg pill per day?)

Thank you Connie, another day in paradise over here! Just me fighting with more sensors

The dose for Cerenia pills (for dogs, because there isnt any "official" dose for cats with the pills) is 2mg/kg (0.9mg/lb) Ive hardly ever used the full dose. Karamelle doesnt take Cerenia on a regular basis. Shes on Ondansetron but when she does, I give her 4mg (shes 11.7lbs). But my cat Oscar also gets 4mg. I give it to him e/o day. He just weighed in at 17.7lbs at the vet. I know its working because Ive tried to cut back more and he doesnt do as well. He does also have CKD however.

Sorry about the low numbers shutting the LIbre down. I hope you can balance everything out to keep her eating and in good numbers. Sending prayers.

Thanks Jo. I’m not sure how I ended up using 16 mg dose. I reduced it to 8 mg this morning (and I’m really hoping I don’t upset her system by doing that since she’s die got B12 tomorrow. I don’t want her crashing today before it’s due )

Thanks for sharing your experience with me

Hi Staci, I looked up the study Wendy mentioned and after that study 14,5 mg (so almost a full pill) would be correct for Ivy. To be honest, I am a bit sceptical because I never found such a high dose for cats anywhere else. But I am not a vet. I wonder if the recommendations in Germany are a bit "conservative" because Cerenia is still off-label use here (don't know about the US). 2mg/kg is the recommendation for dogs here. I keep my fingers crossed, 8 mg (half pill) is doing the job for Ivy!

I hope I didn’t mess her up by cutting her dose in half to 8 mg

I hope not. I would give 8 mg anyway because it seems to be a safe dose.

Should I stay with 16 mg pill?

 

[Wendy&Neko]

If she doesn't need the full dose, no need to give it all. But she can go up to that dose if needed.

I’m not sure how to know if she needs it or not. I’ve been giving that dose over a month now.
A little afraid to reduce (I did give 8 mg today and hoping it’s not a mistake).
How can I tell if she needs the full dose?

 

[Wendy&Neko]

She would start vomiting or show signs of nausea.

Ok, that makes sense.
It’s just hard with her lately with all going on.

She had that last week (same symptoms with diarrhea) but I suspect it was the B12 shot wearing off a day before it was due to be given again.
I had given 16 mg dose as usual, so it wasn’t a Cerenia dose issue.
Thanks Wendy

 

[JoM]

I reduced it to 8 mg this morning

Good luck with the new dose. I hope she still does well. You can always raise it back tomorrow if she seems off. Or you could even try alternating 8mg - 16mg - 8mg for a while.
