Case 11

Because Rintu's tremors are moderate, your initial plan is to administer an intravenous dose of methocarbamol (44 mg/kg). A higher dose of methocarbamol (55 to 220 mg/kg), as well as intravenous diazepam (0.5 to 1 mg/kg) may be given initially if the tremors are severe. Methocarbamol dosing may be repeated if tremors persist, but the total dose should not exceed 330 mg/kg/day. If injectable methocarbamol is not available, oral methocarbamol can be dissolved in water and given rectally. Diazepam, barbiturates, or inhalant anesthesia may be needed in patients with seizures. Diazepam provides poor control of tremors, but after methocarbamol is given, diazepam may reduce hyperesthesia.

If you have a suspected case of toxicosis and are unsure how to proceed, remember you can call the National Animal Poison Control Center (888-426-4435) or the Pet Poison Helpline (800-213-6680); a consultation fee will be charged.

After you administer the methocarbamol, Rintu's muscle tremors are greatly reduced and he appears much more relaxed.
