Major:
ondansetron DULoxetine
Applies to: ondansetron and duloxetine
Using ondansetron together with DULoxetine 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.

19 potential interactions Applies to: 17 conditions, including High Blood Pressure, Depression, Bipolar Disorder, Heart Failure, and Urinary Tract Infection.
Arrhythmia
Major:

ECG changes including QT interval prolongation have been observed in patients receiving ondansetron. Additionally, there have been some postmarketing reports of Torsade de Pointes cases. The use of ondansetron should be avoided in patients with congenital long QT syndrome. ECG monitoring is recommended in patients with electrolyte abnormalities such as hypokalemia or hypomagnesemia, patients with congestive heart failure, bradyarrhythmias, or patients taking other medicines that could lead to QT prolongation.
Bipolar Disorder
Major:
duloxetine
DULoxetine has a major potential interaction with Bipolar Disorder.
Adult and pediatric patients with depression and other psychiatric disorders may experience worsening of their symptoms and may have the emergence of suicidal thoughts and behavior. Patients should be monitored appropriately and observed closely for worsening of their symptoms, suicidality or changes in their behavior, especially during the first few months of treatment, and at times of dose changes. Discontinuing the medication should be considered if symptoms are persistently worse, or abrupt in onset. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
duloxetine
DULoxetine has a moderate potential interaction with Bipolar Disorder.
Therapy with SNRI antidepressants can cause activation of mania and hypomania and should be used with caution in patients with personal or family history of mania, hypomania, bipolar disorder, and other mood disorders.

Moderate:
duloxetine
DULoxetine has a moderate potential interaction with Dehydration.
Treatment with SNRI antidepressants can cause hyponatremia. Caution should be used when treating patients with hyponatremia or at greater risk of hyponatremia such as the elderly, patients taking diuretics or who are volume depleted.
Depression
Major:
duloxetine
DULoxetine has a major potential interaction with Depression.
Adult and pediatric patients with depression and other psychiatric disorders may experience worsening of their symptoms and may have the emergence of suicidal thoughts and behavior.

Diabetes Mellitus
Moderate:
duloxetine
DULoxetine has a moderate potential interaction with Diabetes Mellitus.
In clinical trials, treatment with duloxetine delayed-release worsened the glycemic control in some patients with diabetes. Caution should be used when using duloxetine in diabetic patients and their glycemic levels should be checked regularly.
Glaucoma, Narrow Angle
Moderate:
duloxetine
DULoxetine has a moderate potential interaction with Glaucoma, Narrow Angle.
SNRI antidepressants cause pupillary dilation that may trigger an angle closure attack in patients with anatomically narrow angle without iridectomy.
Heart Failure
Major:

Liver Disease
Major:
duloxetine
DULoxetine has a major potential interaction with Liver Disease.

Moderate:
ondansetron
Ondansetron has a moderate potential interaction with Liver Disease.
Ondansetron is extensively metabolized by the liver. The plasma clearance of ondansetron may be substantially decreased and the half-life prolonged in patients with impaired hepatic function. During clinical trials in patients receiving concomitant chemotherapy, transient elevations of serum transaminases and isolated cases of jaundice have been reported. Therapy with ondansetron should be administered cautiously at reduced dosages in patients with liver disease. The manufacturer recommends a maximum daily dosage of 8 mg in severe hepatic impairment.
