Summary
Nonprescription hemp extract may cause severe liver dysfunction in children. Healthcare providers should monitor liver enzymes in patients using these products and conduct further safety research.
Area of Science:
- Hepatology
- Pediatric Gastroenterology
- Pharmacovigilance
Background:
- Nonprescription cannabis products, including hemp extract, are increasingly accessible for various health concerns.
- The safety profile of these products, particularly non-psychoactive phytocannabinoids, beyond their psychoactive effects, remains under-researched.
- While high doses of recreational tetrahydrocannabinol (THC) and cannabidiol (CBD) are linked to liver issues, data on nonprescription phytocannabinoids is limited.
Observation:
- A 2-year-old unimmunized male with refractory epilepsy was incidentally diagnosed with severe liver dysfunction and elevated coagulation markers.
- The child's parents were administering nonprescription phytocannabinoids (hemp extract) for his neurological condition.
- Liver enzymes normalized after discontinuing the phytocannabinoid product, with the World Health Organization-Uppsala Monitoring Centre classifying the event as a probable adverse reaction.
Findings:
- This case suggests a potential link between nonprescription phytocannabinoid ingestion and severe liver dysfunction in pediatric patients.
- Phytocannabinoids may play a role in the pathophysiology of drug-induced liver injury, even in nonprescription formulations.
- The absence of clinical signs of liver failure despite severe laboratory abnormalities highlights the insidious nature of this adverse reaction.
Implications:
- Increased awareness among healthcare providers and caregivers regarding the potential for life-threatening liver injury from over-the-counter phytocannabinoid products is crucial.
- Routine monitoring of liver enzymes is recommended for pediatric patients using hemp-derived products.
- Further research is urgently needed to elucidate the safety profile of various phytocannabinoids and their impact on different organ systems.

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

Drug Dosing: Infants and Children
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
Pharmacokinetics in Pediatric Patients: Drug Distribution
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
Pharmacokinetics in Pediatric Patients: Drug Metabolism
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...
Pharmacokinetics in Pediatric Patients: Drug Excretion
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
