The median paralytic dose was 200 mg/kg body weight.

These standardized measures were constructed by first calculating median monthly dose of each drug type received in the entire study cohort during the study period.

As of March 2010, no studies on the potential neurotoxicity of mephedrone have been reported, nor is the median lethal dose known.

In animal studies with mice, the median lethal dose was found to be 8 μg tetrodotoxin per kg body weight.

The median lethal dose in mice is 289 mg/kg.

Its estimated median lethal dose is about 927.3 mg/kg in mice.

The median daily dose was 1750 mg, which is 91% of the MTD.

In healthy human hosts, the median infective dose is 132 oocysts.

Some sources quote the median lethal dose (for an average 75 kg opiate-naive individual) as being between 75 and 375 mg.

The median lethal dose is 0.28-0.33 mg/gram of mouse body weight.
