Does Sulfaphenazole Interact with Meloxicam?
Sulfaphenazole and Meloxicam have a unknown drug interaction according to U.S. FDA drug labeling data. Thus concomitant usage of CYP2C9 inhibitors (such as amiodarone, fluconazole, and sulphaphenazole) may lead to abnormally high plasma levels of meloxicam due to reduced metabolic clearance [see Use in Specific Populations (8.8); and Clinical Pharmacology ( 12.3 , 12.5 ) ]. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This information is based on official FDA drug labeling sourced from OpenFDA and the NIH National Library of Medicine.

If you are taking Sulfaphenazole and your doctor is considering prescribing Meloxicam (or vice versa), make sure to:
- Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
- Ask whether the benefits of combining these medications outweigh the risks for your specific situation
- Ask what symptoms to watch for that would indicate the interaction is causing problems
- Never stop or change either medication without first consulting your healthcare provider
