Bismarex (bismuth subsalicylate) Disease Interactions

There are 2 disease interactions with Bismarex (bismuth subsalicylate):

Major

Salicylates (Includes Bismarex) ↔ Reye's syndrome

Severe Potential Hazard, High plausibility. Applies to: Influenza, Varicella-Zoster

The use of salicylates, primarily aspirin, in children with varicella infections or influenza-like illnesses has been associated with an increased risk of Reye's syndrome. Although a causal relationship has not been established, the majority of evidence to date seems to support the association. Most authorities, including the American Academy of Pediatrics Committee on Infectious Diseases, recommend avoiding the use of salicylates in children and teenagers with known or suspected varicella or influenza and during presumed outbreaks of influenza. If antipyretic or analgesic therapy is indicated under these circumstances, acetaminophen may be an appropriate alternative. The same precautions should also be observed with related agents such as salicylamide or diflunisal because of their structural and pharmacological similarities to salicylate.

Moderate

Salicylates (Includes Bismarex) ↔ coagulation

Moderate Potential Hazard, Moderate plausibility. Applies to: Bleeding, Coagulation Defect, Thrombocytopathy, Thrombocytopenia, Vitamin K Deficiency

All salicylates can interfere with the action of vitamin K and induce a dose-dependent alteration in hepatic synthesis of coagulation factors VII, IX and X. At usual recommended dosages, a slight increase in prothrombin time (PT) may occur. Therapy with salicylates, especially if given in high dosages, should be administered cautiously in patients with significant active bleeding or a hemorrhagic diathesis, including hemostatic and/or coagulation defects associated with hemophilia, vitamin K deficiency, hypoprothombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. The same precaution should also be observed with the use of related agents such as salicylamide because of their structural and pharmacological similarities to salicylate.

There are 271 drug interactions with Bismarex (bismuth subsalicylate)

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
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 information available.

Do not stop taking any medications without consulting your healthcare provider.
