You should avoid or limit the use of alcohol while being treated with these medications. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark colored urine, light colored stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. Talk to your doctor or pharmacist if you have any questions or concerns. 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.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
ketoconazole Food/Lifestyle
Applies to: ketoconazole
You should avoid the use of alcohol while being treated with ketoconazole. Ketoconazole may cause liver damage and using it with alcohol or products containing alcohol may increase that risk. In addition, consumption of alcoholic beverages or products containing alcohol during treatment with ketoconazole may trigger a disulfiram-like reaction in some patients, with unpleasant symptoms such as flushing, palpitations, and nausea. Ketoconazole may be taken with or without food. You should avoid consumption of grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with ketoconazole unless directed otherwise by your doctor. Grapefruit juice may increase the blood levels of ketoconazole. This may increase the risk and/or severity of side effects and liver problems. You should seek immediate medical attention if you develop signs and symptoms of liver damage during treatment with ketoconazole, such as joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, light colored stools, and yellowing of the skin or eyes. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs.

Disease interactions
18 potential interactions Applies to: 16 conditions, including High Blood Pressure, Depression, Bipolar Disorder, Urinary Tract Infection, and Seizures.
Achlorhydria
Moderate:
ketoconazole
Ketoconazole has a moderate potential interaction with Achlorhydria.
Nizoral (brand of ketoconazole) tablets require acidity for proper dissolution and absorption. Therefore, the drug may not be effective in patients with achlorhydria. Taking the medication with an acidic beverage such as orange or cranberry juice may help, but an alternative antifungal agent should be considered.
Adrenal Insufficiency
Moderate:
ketoconazole
Ketoconazole has a moderate potential interaction with Adrenal Insufficiency.
Ketoconazole tablets decrease adrenal corticosteroid secretion at doses of 400 mg and higher. Adrenal function should be monitored in patients with adrenal insufficiency or with borderline adrenal function and in patients with prolonged periods of stress due to major surgery, intensive care, etc.
Arrhythmia
Moderate:
ketoconazole
Ketoconazole has a moderate potential interaction with Arrhythmia.
Some azole antifungals have been associated with prolongation of the QT interval on the ECG. Rare cases of QT prolongation and torsade de pointes have been reported during postmarketing experience; such reports usually involved seriously ill patients with multiple confounding risk factors, such as structural heart disease, electrolyte abnormalities, and concomitant medications. These drugs should be administered with caution to patients with potentially proarrhythmic conditions, such as congenital/acquired QT prolongation, cardiomyopathy (especially when heart failure is present), sinus bradycardia, and existing symptomatic arrhythmias. Concomitant use with other medications that have potential to increase the risk of cardiotoxicity should be avoided.
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.
Dehydration
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. 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.
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.
High Blood Pressure
Moderate:
duloxetine
DULoxetine has a moderate potential interaction with High Blood Pressure.
Selective serotonin and norepinephrine reuptake inhibitor antidepressants (SNRIs) have been associated with sustained increases in blood pressure. Therapy with SNRI antidepressants should be administered cautiously in patients with preexisting hypertension. Blood pressure should be assessed prior to initiating treatment and monitored regularly. The dose should be reduced or discontinued if necessary.
Hyponatremia
Moderate:
duloxetine
DULoxetine has a moderate potential interaction with Hyponatremia.
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.
Liver Disease
Major:
duloxetine
DULoxetine has a major potential interaction with Liver Disease.
Postmarketing studies have reported that duloxetine and some other SNRIs like milnacipran may aggravate preexisting liver disease. The use of duloxetine delayed-release and milnacipran should be avoided in patients with chronic liver disease or cirrhosis.
Major:
ketoconazole
Ketoconazole has a major potential interaction with Liver Disease.
Serious hepatotoxicity including cases with a fatal outcome or requiring liver transplant have been reported. Some patients had no obvious risk factors for liver disease. Liver function tests should be performed prior to initiation of therapy and regularly during treatment in patients receiving prolonged therapy with ketoconazole, particularly those with a current or past history of liver disease. Therapy should be withdrawn if persistent elevations or worsening of liver enzyme levels occur, or if the abnormalities are accompanied by symptoms of possible liver injury. Since ketoconazole is primarily metabolized by the liver, empirically reducing the dosage may also be appropriate in patients with existing liver disease. The use of oral ketoconazole tablets is contraindicated in patients with acute or chronic liver disease.
Mania
Moderate:
duloxetine
DULoxetine has a moderate potential interaction with Mania.
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.
