Interaction report

Cannabis and Aspirin, Ethoheptazine, Meprobamate

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Cannabis interacts with whole categories of medication. Aspirin, Ethoheptazine, Meprobamate falls into 2 of those categories, so it can interact with Cannabis in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Aspirin, Ethoheptazine, Meprobamate

Aspirin, Ethoheptazine, Meprobamate falls under CNS DEPRESSANTS — the group Cannabis interacts with.

Theoretically, cannabis might have additive effects if used with other CNS depressants.
Cannabis can have CNS depressant effects. Combining cannabis with other CNS depressants might result in additive or synergistic effects. A small clinical trial in healthy adults shows that inhaling a high-grade cannabis (Bedrocan International B.V., Veendam, The Netherlands) 100 mg, containing delta-9-tetrahydrocannabinol 21.8% and cannabinol 0.1%, modestly increases subjective feelings of sedation when compared with cannabis alone.
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 explains PharmD, Clinical Pharmacist

Here's the part to keep an eye on with Equagesic: it contains meprobamate, a tranquilizer that calms the central nervous system. Cannabis does much the same thing, especially the THC in it. When you stack two things that both slow down the brain, the drowsiness can add up. You may feel more sedated, foggy, dizzy, or slow to react than either one would cause on its own.

Honestly, this is a theoretical concern based on how these substances behave, not strong proof from big studies, so don't panic. But the practical takeaway is real: avoid driving or anything needing sharp focus until you know how the mix hits you, and check in with your doctor or pharmacist before combining them.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Aspirin, Ethoheptazine, Meprobamate also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, cannabis might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In vitro research shows that the cannabis constituents delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) inhibit platelet aggregation.
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

Equagesic combines three medicines, and the one that matters most here is the aspirin. Aspirin already thins your blood by keeping platelets from clumping together to form clots. Lab studies suggest that cannabis compounds (THC and CBD) can also make platelets a bit less sticky, so using both at once could, in theory, add up and raise your bleeding risk slightly.

To be clear, this is a theoretical concern based only on test-tube research, not on solid human studies, so it is far from certain. Still, it is worth watching for things like easy bruising, nosebleeds, bleeding gums, or stomach upset. The meprobamate in this product can also add to cannabis drowsiness. Please check with your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Aspirin, Ethoheptazine, Meprobamate page

“Equagesic combines aspirin with two sedating pain relievers, ethoheptazine and meprobamate, which means supplements can go wrong in two directions at once, and this list earns genuine care before you mix in any of them. Most of the entries add to aspirin's blood-thinning effect and raise bleeding risk, while a large second group deepen…”

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.
