Introduction: Cannabidiol (CBD) is one of the main components of the cannabis plant that has demonstrated anti-epileptic seizure effect. Following its clinical development, in September 2019 the European Medicines Agency approved its indication for the adjunctive therapy of epileptic seizures associated with Lennox-Gastaut syndrome (LGS) and Dravet syndrome (DS), combined with clobazam (CLB), in patients of 2 years of age and older.

Aim: To establish recommendations on the use of plant-derived highly purified CBD on which Spanish experts have reached consensus for the treatment of epilepsy in patients with DS and LGS based on their clinical experience and the scientific evidence.

Development: Consensus meeting with the participation of four Spanish neurologists and neuropediatric who are experts in epilepsy secondary to DS and LGS and with clinical experience in the use and management of CBD.

They discussed on several topics, including posology (starting dose, dose escalation schema), efficacy (assessment of outcomes and indications for treatment withdrawal), and safety (evaluation, drug-drug interactions, adverse events management).

Conclusions: In order to optimise CBD treatment, a slow dose escalation (= 4 weeks) is recommended until the maximum recommended dose or the desire effect is reached.

It is also recommended that the concomitant antiseizure medications (ASMs) be reduced in case of adverse events due to interactions, and that the treatment continues for at least 6 months if it is well tolerated. The efficacy and safety of CBD must be assessed individually, considering the benefits and risks for individual patients.
