Cannabis and Lanreotide

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS

Why this applies to Lanreotide

Lanreotide falls under CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS — the group Cannabis interacts with.

Theoretically, CYP3A4 inhibitors might increase the levels and adverse effects of cannabis.
Delta-9-tetrahydrocannabinol (THC), an active constituent of cannabis, is a substrate of CYP3A4 enzymes.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the interesting twist with this pairing: the concern isn't really about your lanreotide (Somatuline) changing. It's the other way around. THC, one of the main compounds in cannabis, is partly broken down by a liver enzyme called CYP3A4, and lanreotide can act as a mild blocker of that enzyme. So in theory, lanreotide could slow how fast your body clears THC, letting it build up a bit and making cannabis feel stronger (more drowsiness, dizziness, a faster heartbeat, or feeling more impaired).

I want to be honest about how soft this one is. It's theoretical, based on how the drugs work on paper, not on real patient reports. Lanreotide is also a fairly weak enzyme blocker, so any effect is likely small. Still, if you use cannabis, mention it to your doctor or pharmacist so they can keep an eye on things.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

From our pharmacist’s overview on the Lanreotide page

“Every supplement on this page interacts with lanreotide (Somatuline) in the same basic way. Lanreotide, injected to treat acromegaly and certain neuroendocrine tumors, can slow CYP3A4, a liver enzyme that many herbal ingredients depend on to be cleared from the body.”

About Cannabis

What is Cannabis?

Cannabis
  • Chronic pain
  • Nausea and vomiting from chemotherapy
  • Muscle spasticity (e.g., multiple sclerosis)
  • Anxiety and stress
  • Sleep problems
  • Appetite stimulation

Cannabis contains many active compounds, mainly THC (which causes a 'high') and CBD (which does not). Some uses, such as chemotherapy-related nausea, certain seizure disorders, and muscle spasticity, have meaningful evidence, while many other popular uses are not well proven. It can cause real side effects and impairment, so talk to your doctor or pharmacist and follow your local laws before using it.

About Lanreotide Injection

What Is Lanreotide Injection Used For?

Brand name: Somatuline

Lanreotide Injection is used for the long-term treatment of acromegaly (a condition where the body produces too much growth hormone) in patients who have not responded adequately to surgery or radiation, or who cannot have those treatments. The goal is to bring growth hormone and IGF-1 levels back to normal.

It is also used to treat adults with unresectable, well- or moderately-differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) to help slow tumor progression, and to treat adults with carcinoid syndrome, where it reduces how often short-acting rescue medications are needed. If a patient is already receiving Lanreotide Injection for GEP-NETs, no additional dose is given for carcinoid syndrome.
