Medicines – What are they for? Updated July 2017


Ever wonder what all the meds your vet gives you for your bunny are and what they do? Well I sure wondered when I came home with a bunch of different ones recently. So I thought I would post what I know about these drugs and what they are for.

Oxbow Critical Care – this is a supplement made up for ground up hay that you can get from your vet. You can use this to put meds into and then feed by syringe or as a food supplement when your bun has stopped eating.  You should have a bag of this in your fridge at all times as you never know when you will need it. I’ve seen it in a few different flavors.  Plain,  and apple with banana. You normally have to get this from your vet. The expiration is usually pretty far out if bought when fresh. If your batch is about to go bad, mix it with water and plop by the teaspoonful onto a pc  of waxed paper – let them dry out and you have instant bunny treats!

Enrofloxacin  – a liquid, which is an antibiotic to treat a variety of bacteria.

Metronidazole – a liquid, an antibiotic to treat a variety of bacteria.

Pro-Bi (probiotics) – a liquid, which helps promote good bacteria in the intestines. Usually given 1 week longer that antibiotic and other drugs.

Cisapride – a liquid,  used to treat GI Stasis by promoting mobility in the cecum.

Metoclopramide – (Reglan) – a liquid, that is a prokinetic agent that is used to stimulate upper GI mobility during GI Stasis.

Meloxican (Metacam) – a liquid, that is a non-steroidal anti-inflammatory drug (NASAID) that is used to treat pain and inflammation. This seems to be the favorite pain med given for pain to rabbits. But it might not be enough.

Cholestyramine Powder – a powder that binds bile and endotoxins in the GI tract to prevent reabsorption. I put this into critical care.

Infant Gas-X – a liquid, purchased at your local drug store, used to reduce bloating and discomfort or pain associated with gas trapped in the GI tract.

Meclazine – a tablet that helps with vertigo/unbalance.  Can be ground up and put into critical care.

Ciprofloxacin Opthalmic Drop – an eye drop which is an antibiotic.

Triple Antibiotic Ointment – an eye antibiotic ointment. We put a small amount on the inside lower eye lid. Bunny had a eye infection.

Baytril/Banamine/Synotic – a liquid that is an ear drop that is an anti-inflammatory medication.

Buprenorphine/Buprenex – a liquid, used for pain. Its a controlled substance and is in the Opioid family.  This is used when Metacam does not seem to be giving enough relief. I used it along with Metacam and Gabapentin  to control Dino’s pain after dental surgery (see below).

SMZ-TMP (Septra/Bactrim) -a liquid anitbiotic that was given to Dino after a culture was done on an infection in his mouth. It was to treat a very specific bacteria/infection that he had.

Gabapentin is a pain killer not widely used by vets for rabbits but we were in dire straits in trying to treat Dino after dental surgeries for multiple teeth extractions.  Once you give it you can’t just stop  cold turkey or the bunny can have seizures. The bun must be weaned off the drug slowly over a few days.  After a major dental surgery Dino was on Gabapentin, Buprenorphine and Metacam.  Without finding Gabapentin to control his pain, I would have lost him – I know I would have. It was this trifecta of meds that gave him some quality of life and extended his life for us.

Famotidine is an antacid in liquid form.

Panacur (Fenbendazole) is a liquid anti-parasitic that seems to be the new drug of choice to treat  E. Cunniculi. Previously my buns were on something else for e.c. but now this seems to be the drug for treatment as others have confirmed this also.

As I come across new meds, I will try to post about them here.

To see how we gave Dino 14 different meds by mouth using a syringe,  go to this page.

NOTE:  Dino had several pain even after a routine tooth trim. After 3 years of monthly dentals, Metacam was not strong enough. We then added Buprenorphine and eventually Gabapentin to control his pain.

If you have a rabbit that requires a dental surgery or trim, please ask your vet what plan B is if the Metacam does not work.  KNOW what other pain meds can be used and you might even want to have one or both on hand in case you need then. I know there were times when Dino was in pain after a surgery or procedure and I didn’t have the right pain killers. ASLO ask what the MAX dose is in case you need to increase the dosage.
