More severe side effects, which you should contact your doctor about right away, include:
In fact, the FDA has issued warnings to many CBD businesses for illegal practices, including those related to the marketing of their products. In some cases, actual CBD content was negligible or less than 1 percent of what the label claimed.
It is generally started at a dose of 2.5 mg/kg twice per day and increased weekly. It can be increased up to a dose of 20 mg/kg per day if needed, but increased side effects have been found to occur at the higher dose.
When used with other anti-seizure drugs, CBD can cause elevated liver enzymes, which is often a sign of liver injury.
A multitude of CBD-containing products are on the market, and some people have chosen to use them for seizure control. This trend is likely to grow, especially since the 2018 Farm Bill made hemp-derived products, including CBD, legal at the federal level.
Epidiolex comes in an oral solution (liquid form), and the recommended dose is initiated based on weight.
The side effects of CBD that have been reported in the studies when it was added to other antiseizure medications included:

Forty-seven states now allow some form of CBD. Only Idaho, South Dakota, and Nebraska ban all marijuana use. Legal details are different by state, so do your research to make sure you’re on the right side of the law.
Does It Help Psychosis?

Scientists are working to see if it might help with arthritis, and some people with HIV say it helps relieve nerve pain (also called neuropathy). There’s some evidence that it may help muscle spasms linked to multiple sclerosis, too. More research is needed to know for sure.

FDA: “Warning Letters and Test Results for Cannabidiol-Related Products,” “FDA approves first drug comprised of an active ingredient derived from marijuana to treat rare, severe forms of epilepsy.”
On June 25, 2018, the U.S. Food & Drug Administration (FDA) approved EPIDIOLEX ® (cannabidiol, CBD) oral solution for the treatment of seizures associated with two epilepsy syndromes – Lennox-Gastaut syndrome and Dravet syndrome – in people two years of age or older. Epidiolex represents a new medication option for children with these types of epilepsy. It is also the first ever FDA approved medication to treat seizures in Dravet syndrome.
The FDA approval and Drug Enforcement Administration (DEA) scheduling of Epidiolex brings to market the first plant-based drug derived from the cannabis plant in the U.S.
The safety data from the trials in people with Lennox-Gastaut syndrome and Dravet syndrome has shown similar side effects. Tiredness, diarrhea, and upset stomach are reported the most. Interestingly, people getting the placebo also reported diarrhea and upset stomach feeling as well. This may be due to both products being oil.
The 2018 Farm Bill, signed into law by President Trump in December 2018, exempts hemp and hemp-derived products, including CBD, from the Controlled Substances Act. Previously, hemp-derivatives were classified as Schedule I cannabis products, meaning they had no acceptable medical use and had a high potential for abuse. The Farm Bill lifts federal restrictions surrounding CBD and legalizes the cultivation, manufacturing, and sale of these products across the United States. However, this does not mean that all hemp-derived products, including CBD, are medically appropriate.
An Israeli study using a product that had 20 parts of CBD to 1 part of THC was performed in an open-label format for children up to age 18 years with hard to control epilepsy. A significant number of people reported seizure reduction with 7% stating seizures worsened.
