Drug Interactions between fluvoxamine and meloxicam / rizatriptan

Using fluvoxaMINE together with rizatriptan can increase the risk of a rare but serious condition called the serotonin syndrome, which may include symptoms such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, blurred vision, muscle spasm or stiffness, tremor, incoordination, stomach cramp, nausea, vomiting, and diarrhea. Severe cases may result in coma and even death. You should seek immediate medical attention if you experience these symptoms while taking the medications. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with CYP450 2C9 inhibitors may increase the plasma concentration of meloxicam, which has been shown to be primarily metabolized by this isoenzyme. In a study of healthy volunteers, voriconazole, a weak CYP450 2C9 inhibitor increased the systemic exposure of meloxicam by 47% and prolonged the average meloxicam half-life by 51%.

MANAGEMENT: The potential for an interaction should be considered during concomitant use. If coadministration is required, monitor patients for NSAID-related side effects and toxicity including gastrointestinal bleeding or perforation. Dose adjustment of meloxicam may be warranted.
