These ranges are per kg. Enter your guinea pig's weight to get the precise dose and draw-up volume — unit and concentration math done for you.
Irreversibly binds 30S ribosomal subunit, inhibiting bacterial protein synthesis. Concentration-dependent killing with post-antibiotic effect.
Highly nephrotoxic. Monitor renal values. Maintain hydration. Ototoxic. Avoid in dehydrated patients. Neuromuscular blockade risk. Extended-interval dosing preferred.
Species-specific contraindications and adverse-reaction reports for guinea pigs may differ from canine / feline reference data — consult the primary citations listed with each rule.
