Ok I'm Not an expert... not even vet tech but from My research I know that amikacin for humans should be dosed in 15 mg/kg/day dose if she give her 1.5 cc 25mg/ml that's give us 37mg on the single dose.... for one kilo!! and i don't think that that poor spider was that big...
In side effect of this drug You can read:
.....Other manifestations of neurotoxicity may include numbness, skin tingling, muscle twitching, and convulsions.....
.....Patients developing cochlear damage may not have symptoms during therapy to warn them of developing eighth-nerve toxicity, and total or partial irreversible bilateral deafness may occur after the drug has been discontinued. Aminoglycoside-induced ototoxicity is usually irreversible.
Aminoglycosides are potentially nephrotoxic. The risk of nephrotoxicity is greater in patients with impaired renal function and in those who receive high doses or prolonged therapy.
Neuromuscular blockade and respiratory paralysis have been reported following parenteral injection,
And That's are human warning....
Maybe I'm wrong... Hope I'm wrong... But for me looks like vet make a mistake....
I'm really sorry about Your friend lose I know the feeling... I know from autopsy...![]()
