Poor Dennis is a bit grunty!

They are the same. Co Trimoxazole is septrin, which is the same as Sulfatrim. I am really confused as to what your vet is doing.
I was told that there is a Country wide shortage of Co Trimoxazole so Dennis has been given Sulfatrim instead.

The Co Trimoxazole was 40mg/200mg (says this on label of bottle) and the dosage 2ml twice a day.
The Sulftrim is 16mg/ml + 80mg/ml trimethoprim and sulfamethoxazole (says this on box, on label it says 30ml per ml) and the dosage is 0.31ml twice a day.

It's next to impossible to see the vet atm because of the Lockdown and they have also had a positive Covid test in one of the Practice nurses so I have to trust that the vet is doing what is right for Dennis
 
I hope this round of antibiotics does the trick for the lovely Dennis! Is his breathing showing some signs of improvement?

Well he isn't grunting as loud as he was and he doesn't vibrate in his throat when he's breathing which he did at the beginning. He goes in his nebuliser box twice a day too.

I'm glad he's got a bit better and I really hope the Sulfatrim does the trick xx
 
I've just left a message on PetsApp as that seems to have a quicker response time than emailing.
Heard back from the vets. A vet nurse replied saying that the dose was stronger which is why Dennis was prescribed less of it (duh! I already guessed that!) and that it was a 4-6 week course (which I had already worked out for myself!) so not really much help there! Not a very satisfactory response. I need to talk to the Organ Grinder not the Monkey!
 
Just sent this message to my vet :(
Am more than a little worried about Dennis now. Despite extra syringe feeds, antibiotics, probiotics and going in the Nebuliser box twice a day he has lost 125g in 13 days! He has pellets and forage in the morning which he shares with Betsy. He no longer wants his oats with something yummy he also has 24 hour access to hay. Not really sure what else I can do ....
 
Just caught up with this thread, hope all goes well today for Dennis. xx
 
Poor little Dennis, hope it goes well, ask about the Zithromax, it’s given a lot by Simon Maddock for stubborn infections
 
Dennis and I have just got back from the vets.

Rachel had a listen to Dennis's breathing and said it "was not nice at all". She also said that Dennis could have issues going on other than a URI and without and X-ray it would be impossible to tell. She is very relunctant to give him an X-ray as his breathing is so very bad. I mentioned trying Zithromax. Rachel has never used Zithromax on a guinea pig before but she has with rats and rabbits when Baytril and Sulfatrim haven't worked. She said that she was willing to try it if I was and warned me of the side effects (which are the usual ones with antibiotics). She couldn't find anything in her pharmaceutical books about dosage so said that she would medicate as if for a rabbit as their physiology is "quite similar" at 1ml once a day rising to 1ml twice a day if no noticeable effect after 2 days. I'm picking up the Zithromax either tomorrow or Thursday as she has had to order it in. Rachel also warned me that I was to prepare for the worst case scenario in that Dennis might be reaching the end of the road. She did say that as he seems quite bright, alert and is still moving around he is not there yet. I am a realist and I know that if Dennis does reach that stage then I know what I have to do. I have come to think the same thing over the last few days that he is tired of fighting this nasty infection.
 
Poor Denis! Paws crossed that this new medication works, your piggies must have a season ticket to the vets at the moment!

I have certainly paid alot into thier coffers since the start of Lockdown that's for sure! The only one who hasn't been seen there since March is Christian. The others have been regular visitors. Even Patsy who only arrived here in September has been several times!
 
Fingers crossed the new meds will get that nasty bug seen off and Dennis regains this cheeky self back soon x
 
Really hope the zithromax helps. Blackie was prescribed 0.6ml twice a day and she weighed around 1170 grams. I've had 2 other piggies on it in the past and it really helped with a stubborn infection x
