Every held source for this drug and species, as printed. Where they differ, both are shown — the choice is yours, not ours.
The sources disagree for this combination. The ranges below do not overlap on a comparable route. This is not an error in one of them — published veterinary references differ, and reconciling them for a particular patient is a clinical judgement.

Enhances GABA-A receptor activity, increasing chloride conductance. Provides anxiolysis, sedation, muscle relaxation, and anticonvulsant effects.
May cause paradoxical excitement in healthy dogs when used alone. Water-soluble (less painful IM than diazepam). Respiratory depression at high doses. Flumazenil is the reversal agent.
Species-specific contraindications and adverse-reaction reports for green iguanas may differ from canine / feline reference data — consult the primary citations listed with each rule.
Midazolam dose ranges in green iguanas, with cited source references: IM 2 mg/kg single dose; IM 2 mg/kg single dose (sedation); no repeat interval stated. Reference ranges from cited sources — verify against current literature before clinical use.

These are general warnings for Midazolam across species; consult the green iguana dosing table above for species-specific guidance. May cause paradoxical excitement in healthy dogs when used alone.

Why a species-specific page? Midazolam pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in green iguanas — the rules above are the citations specific to this species, not generic recommendations.
