Diclofex DC (capsaicin / diclofenac topical) Disease Interactions

There are 2 disease interactions with Diclofex DC (capsaicin / diclofenac topical):

Major

Nsaids (Includes Diclofex DC) ↔ Asthma

Severe Potential Hazard, High plausibility

Applies to: Asthma

Approximately 10% of patients with asthma may have aspirin-sensitive asthma, characterized by nasal polyposis, pansinusitis, eosinophilia, and precipitation of asthma and rhinitis attacks after ingestion of aspirin. The use of aspirin in these patients has been associated with severe bronchospasm and fatal anaphylactoid reactions. Since cross-sensitivity has been noted between aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), therapy with any NSAID should be avoided in asthmatic patients with a history of aspirin or other NSAID sensitivity, and administered cautiously in all patients with preexisting asthma. Prior to initiating therapy with NSAIDs, patients should be questioned about previous allergic-type reactions to these agents. Salicylate salts, salsalate, salicylamide, and acetaminophen may be appropriate alternatives in patients with a history of NSAID-induced bronchospasm, since cross-sensitivity to these agents appears to be low. However, cross-sensitivity has been demonstrated occasionally with high dosages of these agents (e.g., acetaminophen >= 1000 mg), thus it may be appropriate to initiate therapy with low dosages and increase gradually. There is some evidence suggesting that COX-2 inhibitors may be safely used in patients with aspirin-sensitive asthma, although the labeling for these products contraindicate such use. If necessary, aspirin desensitization may also be attempted in some patients under medical surveillance.

Moderate

Nsaids (Includes Diclofex DC) ↔ Platelet Aggregation Inhibition

Moderate Potential Hazard, Moderate plausibility

Applies to: Coagulation Defect, Thrombocytopenia, Vitamin K Deficiency

Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients. With the exception of aspirin, the platelet effects seen with most NSAIDs at usual recommended dosages are generally slight and of relatively short duration but may be more pronounced in patients with underlying hemostatic abnormalities. Thrombocytopenia has also been reported rarely during NSAID use. Therapy with NSAIDs 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, hypoprothrombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. NSAIDs that selectively inhibit cyclooxygenase-2 (i.e., COX-2 inhibitors) do not appear to affect platelet function or bleeding time at indicated dosages and may be preferable if risk of bleeding is a concern.

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.
