Dapsone Disease Interactions

There are 2 disease interactions with dapsone.

Major

Dapsone (applies to dapsone) bone marrow suppression

Major Potential Hazard, High plausibility. Applicable conditions: G-6-PD Deficiency, Bone Marrow Depression/Low Blood Counts

The use of dapsone has been associated with development of agranulocytosis, aplastic anemia, and other blood dyscrasias. Blood dyscrasias are more likely to occur in patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. Patients should be instructed to report any signs of infection (sore throat, fever, local infection, bleeding, or symptoms of anemia). Monitoring for hematologic abnormalities is recommended.

Moderate

Dapsone (applies to dapsone) liver disease

Moderate Potential Hazard, Moderate plausibility.

The use of dapsone has been associated with the development of hyperbilirubinemia. Patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency are more likely to develop hyperbilirubinemia. Monitoring liver function is recommended and discontinuation of the drug may be necessary.

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.
