I have a 5 year old bunny who has been on SMZ/TMP (liquid)every month for a few years now. I was recently told I may be able to use a bottle of liquid SMZ/TMP even though it expired a few days ago. Is this safe for my bunny or should I just order another bottle? They seem to go bad before she can use it all. I am currently ordering the 16 oz. bottle.
I would greatly appreciate your opinion or thoughts on this matter.
Answer Dear Jennifer,
First question: Do you mean that you give the bunny SMZ/TMP once a month? That seems...odd. Please clarify, so I can give you a better answer.
What dose, and for how long each month? For what reason?
It's not a good idea to give antibiotics long-term without a really good reason. Just saying.
A medication that expired only a few days is almost certainly still fine to use, though.
I've lived with companion rabbits for more than 35 years, and consider them members of my family. I can answer any questions about the biology and health of rabbits, from the commonplace to the unusual. But please note:
RULE #1: THE INTERNET IS NOT THE PLACE TO SEEK HELP IN AN EMERGENCY.
If your rabbits is LETHARGIC
If your rabbit is NOT EATING
If your rabbit is PHYSICALLY INJURED (including broken bones)
I have been rescuing and rehabilitating domestic and wild rabbits for about 30 years.
I have written articles for many rabbit rescue publications, as well as for the veterinary journal, Exotic DVM.
