Heparin
For an informed discussion with your doctor or pharmacist. This information collection is not a clinically validated interaction checker. Missing data do not establish safety. Do not change or stop prescribed medicines on the basis of this information. The findings apply to the specific conditions studied; laboratory and animal studies cannot be directly extrapolated to humans.
Active substance: Heparin
Examples of brand names: Liquemin [DE]
ATC code: B01AB01
Main use (for orientation): Anticoagulation
Documented research summary
No direct cannabinoid-pair finding. Heparin is not equated with warfarin, low-molecular-weight heparins or combination products.
Uncertainties and limitations
Corrected to intravenous unfractionated heparin sodium in NaCl. NOT Defencath taurolidine catheter lock, NOT low-molecular-weight heparins.
Shared enzymes must not be equated with clinical evidence of an interaction; CBD/THC findings cannot be extrapolated to other cannabinoids.
Research is limited to the specified date and protocol; it is not globally exhaustive. Brand names and authorisations do not constitute a complete current market overview.
Structured assessment
Category: Drug context
Cannabinoid scope: 28 register names in the documented search family; neither 28 individual clinical trials nor a blanket assessment of all cannabinoids.
Evidence status: Insufficient pair-specific data
Mechanism / drug context: Unfractionated heparin: saturable cellular elimination, additional renal involvement.
Type of supporting material: Medicine information and documented individual review; no positive pair trial
Clinical interpretation: Requires individual assessment by a doctor or pharmacist. Lack of evidence does not establish safety; no dosage or discontinuation advice is provided.
Drug context and gaps in search results are not measured interactions. The source role below describes which statement the source actually supports.
Source role [V2_LABEL_D0017_Heparin]: Drug context
Statement supported: Supports dosage form, metabolism and/or known risks; alone, it does not substantiate a cannabinoid–drug pair finding.
Source: Heparin Sodium in Sodium Chloride Injection, intravenous [V2_LABEL_D0017_Heparin]
Scope of review: Individual research with documented title/abstract screening and targeted review of original sections. This is not exhaustive evidence that interactions are absent.
Unresolved source question: The complete stored individual review, label review, literature screening, conclusion and uncertainties were read. Targeted sections of original information were rechecked; no claim is made that all product information or full texts were completely revalidated.
Separately recorded findings
No separately substantiated finding for this drug–cannabinoid pair is recorded within the documented scope of review. This does not prove that no such study exists anywhere or that the combination is safe.
