Meta Information
ID:glucosamine
Name:
Schema Version:AIM-2.0
Interactions
Target id:
/class/anticoagulants-antiplatelets
Target name:
Anticoagulants and Antiplatelets (e.g., Warfarin)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Glucosamine may enhance the anticoagulant effect of drugs like warfarin, increasing the International Normalized Ratio (INR) and elevating the risk of bleeding.
Actionable advice:
Avoid using glucosamine if you are taking warfarin or other blood thinners unless approved and closely monitored by your doctor.
Target id:
/condition/shellfish-allergy
Target name:
Shellfish Allergy
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Most glucosamine supplements are derived from the shells of shellfish (e.g., shrimp, crab, lobster), which can trigger a severe allergic reaction in susceptible individuals.
Actionable advice:
Avoid completely if you have a shellfish allergy; seek out vegetarian (corn-derived) sources of glucosamine instead.
Target id:
/class/chemotherapy-radiation
Target name:
Chemotherapy (Topoisomerase II Inhibitors)
Severity:
major
Interaction type:
diminishing
Nature:
absolute
Temporal spacing:
null
Description:
Some laboratory and animal studies suggest that glucosamine may interfere with the effectiveness of certain chemotherapy drugs like etoposide, doxorubicin, and teniposide, potentially reducing their cancer-fighting ability.
Actionable advice:
Avoid taking glucosamine during chemotherapy, especially with topoisomerase II inhibitors, unless specifically cleared by your oncologist.
Target id:
/condition/diabetes-mellitus
Target name:
Diabetes Mellitus
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
As an amino sugar, glucosamine can potentially affect glucose metabolism and insulin resistance, possibly leading to increased blood sugar levels in some individuals with diabetes.
Actionable advice:
If you have diabetes, monitor your blood glucose levels closely when starting or stopping glucosamine and consult your doctor.
Target id:
/class/antidiabetic-medications
Target name:
Diabetes Medications
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
By potentially increasing blood glucose levels, glucosamine may counteract the effects of medications intended to lower blood sugar, requiring possible dose adjustments.
Actionable advice:
Consult your doctor before use; you may need to monitor blood sugar more frequently and adjust your medication dosage.
Target id:
/condition/glaucoma
Target name:
Glaucoma
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Some research indicates that glucosamine supplementation may increase intraocular pressure (IOP), which could worsen glaucoma.
Actionable advice:
Avoid glucosamine if you have glaucoma, or use only under the supervision of an ophthalmologist with regular eye pressure monitoring.
Target id:
/dietary/meal
Target name:
Any Caloric Meal
Severity:
moderate
Interaction type:
requirement
Nature:
temporal
Temporal spacing:
Hours before target:
0
Hours after target:
0
Description:
Glucosamine can cause gastrointestinal side effects such as nausea, heartburn, or stomach upset in some individuals when taken on an empty stomach.
Actionable advice:
Always take glucosamine with a meal or a snack to improve tolerance and minimize digestive discomfort.
Target id:
/intervention/chondroitin-sulfate
Target name:
Chondroitin Sulfate
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Temporal spacing:
null
Description:
Glucosamine and chondroitin are both structural components of cartilage and are thought to work together to support joint health, with some studies showing a combined effect superior to either alone.
Actionable advice:
Consider taking glucosamine and chondroitin together for potentially enhanced joint support benefits.
Target id:
/condition/pregnancy
Target name:
Pregnancy
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
There is insufficient reliable data on the safety of glucosamine supplementation during pregnancy.
Actionable advice:
Avoid using glucosamine during pregnancy due to a lack of safety information.
Target id:
/condition/lactation
Target name:
Breastfeeding (Lactation)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
It is not known whether glucosamine is excreted in human breast milk or what its effects might be on a nursing infant.
Actionable advice:
Avoid using glucosamine while breastfeeding due to a lack of safety information.
Target id:
/condition/asthma-copd
Target name:
Asthma
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
There are isolated case reports suggesting a possible link between glucosamine supplementation and the exacerbation of asthma symptoms.
Actionable advice:
Use with caution if you have asthma and discontinue use if you notice a worsening of your respiratory symptoms.
Target id:
/intervention/acetaminophen
Target name:
Acetaminophen (Paracetamol)
Severity:
minor
Interaction type:
diminishing
Nature:
absolute
Temporal spacing:
null
Description:
Some research suggests that taking glucosamine and acetaminophen together might reduce the effectiveness of both substances, though the clinical significance is unclear.
Actionable advice:
Be aware that the pain-relieving effects of either substance may be slightly reduced if taken concurrently.
Target id:
/class/diuretics
Target name:
Diuretics (Water Pills)
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Theoretically, glucosamine sulfate contains sodium or potassium salts which could interact with diuretics, although this is not well-documented in clinical practice.
Actionable advice:
Use with caution and consult your doctor, particularly if you are on a potassium-sparing diuretic or have kidney issues.
Target id:
/biomarker/fasting-glucose
Target name:
Fasting Glucose
Severity:
minor
Interaction type:
assay_interference
Nature:
temporal
Temporal spacing:
Hours before target:
12
Hours after target:
0
Description:
Because glucosamine can influence glucose metabolism, taking it before a blood test may slightly alter the results, potentially causing a falsely elevated reading.
Actionable advice:
Avoid taking your glucosamine dose on the morning of a scheduled fasting blood glucose test for the most accurate result.
