Interactions between your drugs

Moderate

ginger cangrelor

Applies to: B-Nexa (calcium / folic acid / ginger / pyridoxine) and cangrelor

MONITOR: Ginger may potentiate the effects of anticoagulants, platelet inhibitors and thrombolytic agents, possibly increasing the risk of bleeding. Limited data suggest that ginger may decrease platelet aggregation via the inhibition of thromboxane synthetase, although some studies have found no effect on platelet function or thromboxane production or activity. Nevertheless, the interaction was suspected in a 76-year-old patient stabilized on coumarin therapy who developed epistaxis following use of ginger products (pieces of dried ginger, tea from ginger powder) for several weeks. Her INR was greater than 10 (target INR 2.0 to 3.0) and partial thromboplastin time (PTT) was 84.4 seconds (normal less than 35 seconds) upon hospital admission. INR and PTT values normalized after ginger intake was stopped and vitamin K given. In contrast, an investigative study found no significant effect of ginger pretreatment for 7 days on clotting status or the pharmacokinetics or pharmacodynamics of a single 25 mg dose of warfarin in 12 healthy volunteers.

MANAGEMENT: Patients should consult a healthcare provider before taking any herbal or alternative medicine. In patients who have used ginger and ginger supplements extensively prior to receiving anticoagulation, antiplatelet or thrombolytic therapy, the potential for an interaction should be considered. Close clinical and laboratory observation for hematologic complications is recommended. Patients should be advised to promptly report any signs of bleeding to their physician, including pain, swelling, headache, dizziness, weakness, prolonged bleeding from cuts, increased menstrual flow, vaginal bleeding, nosebleeds, bleeding of gums from brushing, unusual bleeding or bruising, red or brown urine, or red or black stools.

Drug and food interactions

Moderate

folic acid food

Applies to: B-Nexa (calcium / folic acid / ginger / pyridoxine)

MONITOR: Ethanol may increase folic acid elimination and folic acid absorption is decreased in chronic alcoholics. Excessive alcohol consumption may lead to folate deficiency.

MANAGEMENT: Monitoring of patient response to folic acid supplementation if they also consume alcohol regularly may be recommended.

Moderate

calcium phosphate, tribasic food

Applies to: B-Nexa (calcium / folic acid / ginger / pyridoxine)

ADJUST DOSING INTERVAL: Administration with food may increase the absorption of calcium. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption.

MANAGEMENT: Calcium may be administered with food to increase absorption. Consider withholding calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
