Harm Potential

Addiction & Dependence

Psychological

High

Animal studies indicate abuse potential comparable to cocaine and amphetamine, suggesting a significant risk of psychological dependence and compulsive patterns of use.

Toxicity

Lethal Dosage

One reported fatality involved blood concentrations of 21.3 mg/L with concurrent diazepam use. Doses above 15-20mg are considered dangerous.

LD50 Data
SpeciesRouteValue
mouseoral17 mg/kg
Pulmonary

Pulmonary hypertension has been associated with 4-methylaminorex use, similar to the related appetite suppressant aminorex which caused an epidemic of pulmonary hypertension.

Central Nervous System

High doses in animal studies caused reduction in tryptophan hydroxylase activity, a possible marker for serotonin neurotoxicity; the highest doses tested caused clonic seizures and some deaths in rats.

Seizure Risk

Moderate

High doses have caused clonic seizures in rat studies, with some fatalities occurring at the highest doses tested (20 mg/kg).
