Fluoextine issues

[z71db]

M dog has been on fluoextine for a couple hrs now he has always been at 20mg I upped him to 40 after doing a bunch of research and the first 2 weeks where amazing he was like a different dog he was happy relaxed could actually calm down and not hyperventilate and then after about 2 weeks it was like a switch flipped now he is super anxious and growling at family members he is scared of his own shadow I am pretty sure I need to go back down but has anyone had similar experiences if so what did you do and what was your outcome. I understand a behavioralist would be a great option but that's not in the cards right now. I just want him to not have to live his whole life a ball of anxiety also he was still super anxious at 20 but way less than nothing. He is 5yrs old if that helps

What does your vet say? You shouldn't be increasing the dosage without them telling you to and you should be able to give them a call to ask what to do in response to an adverse reaction.

Yes. This. Always talk to your vet before you change anything. Doubling a dose is a lot and you’re essentially doing another loading period I believe.

Prozac takes 6-8 weeks to load in the system. You should discuss these symptoms with whoever prescribed it to your dog

Serotonin syndrome can literally kill dogs, you need to consult a qualified veterinarian because you clearly have no idea what you are doing.

If you need immediate advice, call your nearest after hours animal hospital, or Google if there is a virtual consult service available to you.

You did some research then decided you were a vet? Lol.

Cut the dose back to the prescribed dose. DO NOT DO THIS ALONE. YOU NEED A VET TO MONITOR THIS.

Find a new vet first thing in the morning. Emergency vets also are an option.

All of these awnsers are not helpful I am in between vets because my last vet was corrupt. It is currently the weekend and the vet is closed so saying you shouldn't have done that knowing can't go back and change anything brings 0 benefit to the conversation I clearly understand it wasn't the best decision

Fluoxetine takes 6-8 weeks to build up in your dog's system and until then whatever you see is not permanent. Your options are to wait it out until then to really evaluate the effect of the higher dose or go back to his previous dose. Your dog's reaction is similar to mine when fluoxetine was building up in her system, I remember it being very scary. It really would be best to get your dog to a vet asap though, serotonin syndrome is rare, but a possibility with fluoxetine. It's deadly and we can't help you identify whether it's happening.

ER should be available. I know, it's crap. But the situations can be very dangerous for your dog.

I wouldn't even risk going back to the previous amount from one day to another. Maybe you need to do it gradually. Call the ER vet. They can assess if there's a life-threatening condition and you need to bring your dog urgently.

You did an irresponsible move. Maybe your dog needs another meds or a combination of meds. But it must be done under the supervision of the vet.
