Drug interactions
Moderate drug interactions
Moderate:
dextromethorphan osilodrostat
Applies to: Iophen DM NR (dextromethorphan / guaifenesin) and osilodrostat
Osilodrostat may increase the blood levels and effects of dextromethorphan. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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:
dextromethorphan Food/Lifestyle
Applies to: Iophen DM NR (dextromethorphan / guaifenesin)
Alcohol can increase the nervous system side effects of dextromethorphan such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with dextromethorphan. Do not use more than the recommended dose of dextromethorphan, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
Disease interactions
8 potential interactions Applies to: 8 conditions, including Heart Failure, Arrhythmia, Hypokalemia, Adrenal Insufficiency, and Liver Disease.
Adrenal Insufficiency
Moderate:
osilodrostat
Osilodrostat has a moderate potential interaction with Adrenal Insufficiency.
Osilodrostat lowers cortisol levels and can lead to hypocortisolism and sometimes life-threatening adrenal insufficiency. Patients should be evaluated for precipitating causes of hypocortisolism. Serum/plasma cortisol, 24-hour urine free cortisol, and patient's signs/symptoms should be monitored periodically during treatment. Osilodrostat should be decreased or temporarily discontinued if urine free cortisol levels fall below the target range, there is a rapid decrease in cortisol levels, and/or patients report hypocortisolism symptoms. Therapy should be stopped and exogenous glucocorticoid replacement therapy should be administered if serum/plasma cortisol levels are below the target range and patients have symptoms of adrenal insufficiency. Osilodrostat should be restarted at a lower dose when urine free cortisol and serum/plasma cortisol levels are within the target range, and/or patient symptoms have resolved.
Arrhythmia
Moderate:
osilodrostat
Osilodrostat has a moderate potential interaction with Arrhythmia.
The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds. Hypokalemia and hypomagnesemia should be corrected before initiating treatment and monitored regularly during treatment. Electrolyte abnormalities should be corrected if indicated. Care should be exercised when using this agent in patients with risk factors for QT prolongation and more frequent ECG monitoring should be considered.
Electrolyte Abnormalities
Moderate:
osilodrostat
Osilodrostat has a moderate potential interaction with Electrolyte Abnormalities.
The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds. Hypokalemia and hypomagnesemia should be corrected before initiating treatment and monitored regularly during treatment. Electrolyte abnormalities should be corrected if indicated. Care should be exercised when using this agent in patients with risk factors for QT prolongation and more frequent ECG monitoring should be considered.
Heart Failure
Moderate:
osilodrostat
Osilodrostat has a moderate potential interaction with Heart Failure.
The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds. Hypokalemia and hypomagnesemia should be corrected before initiating treatment and monitored regularly during treatment. Electrolyte abnormalities should be corrected if indicated. Care should be exercised when using this agent in patients with risk factors for QT prolongation and more frequent ECG monitoring should be considered.
Hypokalemia
Moderate:
osilodrostat
Osilodrostat has a moderate potential interaction with Hypokalemia.
The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds. Hypokalemia and hypomagnesemia should be corrected before initiating treatment and monitored regularly during treatment. Electrolyte abnormalities should be corrected if indicated. Care should be exercised when using this agent in patients with risk factors for QT prolongation and more frequent ECG monitoring should be considered.
Liver Disease
Moderate:
osilodrostat
Osilodrostat has a moderate potential interaction with Liver Disease.
Dosage adjustment of osilodrostat is required for patients with moderate to severe liver dysfunction. The recommended starting dose for patients with moderate liver dysfunction is 1 mg orally twice a day, and for patients with severe liver dysfunction is 1 mg orally once a day in the evening. No dose adjustment is required in patients with mild liver dysfunction. More frequent monitoring of adrenal function may be needed during dose titration in all patients with liver dysfunction.
Magnesium Imbalance
Moderate:
osilodrostat
Osilodrostat has a moderate potential interaction with Magnesium Imbalance.
The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds. Hypokalemia and hypomagnesemia should be corrected before initiating treatment and monitored regularly during treatment. Electrolyte abnormalities should be corrected if indicated. Care should be exercised when using this agent in patients with risk factors for QT prolongation and more frequent ECG monitoring should be considered.
Renal Dysfunction
Moderate:
osilodrostat
Osilodrostat has a moderate potential interaction with Renal Dysfunction.
No dosage adjustment of osilodrostat is required for patients with impaired renal function. However, in patients with moderate to severe renal dysfunction, urinary free cortisol (UFC) levels should be interpreted with caution due to reduced UFC excretion.
