7 days on Bactrim URI Symptoms not going away

[HarlowDarling]

Hello, well my guinea pig has been on Bactrim for 7 days now for his URI. He started off sneezing and having a runny nose (only slightly) but his cage mate didn't have any of the symptoms at all. Anyway both of the boys were given Bactrim to take for 10 days (twice a day).
My boy who was sneezing now seems to have an even runnier nose than he had to begin with! And it's really weird, it seems to be completely on and off! Is this normal? I expected that the symptoms would have gone by 5 days... His friend shows no symptoms at all though. Both boys are eating and acting normal.
Should I take him to the vets if his nose is still runny, or should I wait out until he has finished the full course of antibiotics...?

Has this happened to anyone else before? I am starting to think it is allergy related? I live in Australia and it is spring here...When he is indoors he actually seems quite alright, but I just went and put the boys in their outside enclosure on the grass and he did a big sneeze.

Please always finish a course of antibiotics if prescribed, just as you would for yourself or else they are ineffective. It may be that his infection is not responding to that particular antibiotic and another one may have better effect but you need to discuss that with your vet. It is also possible that he is having issues with something in his environment.

Does changing his bedding material to something else help? Maybe trial them on something different for a few days to see if he improves....

Also make sure they are getting enough Vitamin C as in addition to other problems a lack of it does give a piggy a runny nose and eyes.

You could also try phoning your vet for some advice, they may suggest a different anti-biotic but as MerryPip says please finish the course
