Lower Maintenance CBD Doses Accompanied More Adverse Events in an Epilepsy Series
In the adult epilepsy series, patients with adverse events had lower achieved maintenance CBD doses. That observational association did not establish that lower doses caused more adverse effects or that higher doses were safer.
The reported dose was the achieved regimen
The study compared maintenance dosing in patients with and without recorded adverse events. The median was 7 mg/kg/day in the adverse-event group and 12.5 mg/kg/day in the other group, with a significant comparison. Maximum-dose differences did not reach statistical significance.
Treatment adjustment can reverse the apparent direction
An adverse event can lead clinicians to reduce or limit a dose. Thus, the achieved maintenance amount may partly be a consequence of tolerability rather than a randomly assigned exposure that caused the event. The retrospective comparison cannot isolate which direction explains the observed association.
The result does not justify dose escalation
The cohort did not establish a protective higher-dose strategy. Other antiseizure medicines changed, patients differed in clinical circumstances, and there was no randomized dose comparison. A careful account names the achieved-dose variable and the timing problem. This preserves a clinically informative treatment pattern while avoiding the mistaken conclusion that a statistically significant inverse association establishes a safer or more effective personal dose.
