There is no effective treatment for antibiotic toxicity in guinea pigs other than general support and discontinuing the antibiotics.
Living and Management
The guinea pig that is recovering from antibiotic toxicity should be monitored carefully for a relapse of any allergic symptoms. Consult your veterinarian about your guinea pig's dietary requirements during the recovery period, as they may need to be adjusted during this time. Follow the recommendations made by your veterinarian to help your pet guinea pig to recover quickly.
In general, you should avoid giving your guinea pig any antibiotics unless you have been specifically directed to do so by a veterinarian that is familiar with your pet. If your guinea pig must take antibiotics, you will need be familiar with the signs of antibiotic toxicity, monitor its health carefully, and immediately consult your veterinarian if any abnormal symptoms arise.
