4% of people taking EPIDIOLEX 20 mg/kg/day (compared with 0% of people taking placebo) reported no drop seizures. In another study, 4% of people taking EPIDIOLEX 10 mg/kg/day and 7% who took EPIDIOLEX 20 mg/kg/day (compared with 1% of people taking placebo) reported no drop seizures.

Substantial reduction in drop seizures

3x more people living with LGS saw a substantial reduction of 75% or greater in their drop seizures with EPIDIOLEX 10 mg/kg/day (11%), compared with placebo (3%).

Three individuals

More than 500 participants

More than 500 people with LGS and Dravet syndrome took part in 3 clinical studies—the largest placebo-controlled, clinical study program of these conditions to date. Even after these trials were completed, the majority of people continued taking EPIDIOLEX for more than a year.

Included patients who failed on several medicines

EPIDIOLEX clinical trials included people who had typically failed on 4-6 prior antiseizure medicines. These people were typically also taking 3 antiseizure medicines at the time, but their seizures were still uncontrolled.

Most common side effects

The most common side effects of EPIDIOLEX include increase in liver enzymes, sleepiness, decreased appetite, diarrhea, fever, vomiting, feeling very tired and weak, rash, sleep problems, and infections.

Common questions

At 20 mg/kg/day doses, there was a somewhat greater reduction in seizure rates than with 10 mg/kg/day doses; however, there was also an increase in EPIDIOLEX side effects.

*The S/CGIC is a 7-point scale that ranges from “Very Much Improved” to “Very Much Worse,” evaluating patient or caregiver assessment of the patient’s overall condition from the beginning of the study to the end of the study.

Patients who stayed on EPIDIOLEX after the initial trial maintained seizure reduction in a 3-year open-label phase.

Three individuals

More than 200 participants

More than 200 people with TSC took part in a clinical trial to determine if EPIDIOLEX reduced the rate of seizures associated with TSC. After this trial was completed, almost all patients continued taking EPIDIOLEX as part of an extension of the study.

Two pills stacked on top of each other

Included patients who failed on several medicines

People with TSC in the EPIDIOLEX clinical trial had typically failed on 4 prior antiseizure medicines. They were also taking an average of 3 antiseizure medicines at the time of the study, but their seizures were still uncontrolled.

Most common side effects

The most common side effects of EPIDIOLEX include increase in liver enzymes, sleepiness, decreased appetite, diarrhea, fever, vomiting, feeling very tired and weak, rash, sleep problems, and infections.

Common questions

EPIDIOLEX can be used in combination with many commonly prescribed antiseizure medicines. In this study, the most common antiseizure medicines patients had taken, while also taking EPIDIOLEX, were valproate, vigabatrin, levetiracetam, and clobazam.

Patients who stayed on EPIDIOLEX after the initial trial maintained seizure reduction in a 3-year open-label phase.

REDUCTIONSEIZURE

*TSC-associated seizures included different types of partial onset (focal) seizures and generalized seizures.

Common EPIDIOLEX cannabidiol side effects and interactions

Common EPIDIOLEX side effects and interactions

EPIDIOLEX may cause liver problems. Your doctor may order blood tests to check your liver before you start taking EPIDIOLEX and during treatment. In some cases, EPIDIOLEX treatment may need to be stopped. Call your doctor right away if you start to have any of these signs and symptoms of liver problems during treatment with EPIDIOLEX:

  • loss of appetite, nausea, vomiting
  • fever, feeling unwell, unusual tiredness
  • yellowing of the skin or the whites of the eyes (jaundice)
  • itching
  • unusual darkening of the urine
  • right upper stomach area pain or discomfort

Your doctor may order blood tests to monitor for other EPIDIOLEX side effects.

EPIDIOLEX may cause you to feel sleepy, which may get better over time. Other medicines (e.g., clobazam) or alcohol may increase sleepiness. Do not drive, operate heavy machinery, or do other dangerous activities until you know how EPIDIOLEX affects you.

Like other antiepileptic drugs, EPIDIOLEX may cause suicidal thoughts or actions in a very small number of people, about 1 in 500. Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • attempt to commit suicide
  • new or worse depression
  • new or worse anxiety
  • feeling agitated or restless
  • panic attacks
  • trouble sleeping (insomnia)
  • new or worse irritability
  • acting aggressive, being angry, or violent
  • acting on dangerous impulses
  • an extreme increase in activity and talking (mania)
  • other unusual changes in behavior or mood

How can I watch for early symptoms of suicidal thoughts and actions?

  • Pay attention to any changes, especially sudden changes in mood, behaviors, thoughts, or feelings
  • Keep all follow-up visits with your healthcare provider as scheduled

Do not stop taking EPIDIOLEX without first talking to your healthcare provider. Stopping a seizure medicine such as EPIDIOLEX suddenly can cause you to have seizures more often or seizures that do not stop (status epilepticus).

Call your healthcare provider between visits as needed, especially if you are worried about symptoms.

Do not take EPIDIOLEX if you are allergic to cannabidiol or any other ingredients in EPIDIOLEX.

  • The most common side effects include increase in liver enzymes, sleepiness, decreased appetite, diarrhea, fever, vomiting, feeling very tired and weak, rash, sleep problems, and infections
  • Across studies in LGS, Dravet syndrome, and TSC, EPIDIOLEX was found to have a consistent safety profile in both children and adults
  • In the LGS and Dravet syndrome studies, the rate of discontinuation (patients who stopped taking the medicine) for any side effect was 1% for patients taking placebo and 3% for patients taking EPIDIOLEX 10 mg/kg/day. For patients taking EPIDIOLEX 20 mg/kg/day, the rate of discontinuation for any side effect was 12%
  • In the TSC study, the rate of discontinuation for any side effect was 3% for patients taking placebo and 11% for patients taking EPIDIOLEX 25 mg/kg/day
  • The most frequent causes of discontinuation were increase in liver enzymes and sleepiness in the LGS and Dravet syndrome studies, and rash in the TSC study
  • EPIDIOLEX can cause weight loss
  • Your doctor may also order blood tests to look out for other side effects
  • These are not all of the possible EPIDIOLEX side effects. For more information, ask your healthcare provider or pharmacist

EPIDIOLEX may interact with some antiseizure medicines or other medicines you are taking. Do not start or stop other medicines without talking to your doctor. Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, herbal supplements, and cannabis-based products.
