Drug interactions
Major drug interactions
Major:
palonosetron etrasimod
Applies to: palonosetron and etrasimod
Before starting etrasimod, let your doctor know if you are currently receiving treatment with palonosetron. Using etrasimod in this situation can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect.
You may also be more susceptible if you have:
- a heart condition called congenital long QT syndrome
- other cardiac diseases
- conduction abnormalities
- electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting)
Talk to your doctor if you have any questions or concerns.
You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether together or alone.
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.

Moderate food/lifestyle interactions
Moderate:
etrasimod Food/Lifestyle

Grapefruit juice may increase the blood levels of etrasimod.
You should avoid grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with etrasimod unless directed otherwise by your doctor.
Talk to your doctor if you have any questions or concerns.
Contact your doctor if your condition changes or you experience increased side effects, such as fever, high temperature or flu-like symptoms, severe headache, confusion, seizures, dizziness, tiredness, lightheadedness, chest pain, shortness of breath, or irregular or abnormal heartbeat, blurriness or shadows in the center of your vision, and nausea, vomiting, abdominal pain, anorexia, or jaundice and/or dark urine.

Disease interactions
8 potential interactions Applies to: 7 conditions, including Heart Disease, Liver Disease, Skin Cancer, Infection, and Cardiovascular Conditions and Disorders.
Cardiovascular Conditions and Disorders
Major:
etrasimod
Etrasimod has a major potential interaction with Cardiovascular Conditions and Disorders.
Etrasimod is contraindicated in patients who have experienced in the last 6 months myocardial infarction, unstable angina pectoris, stroke, transient ischemic attack, decompensated heart failure requiring hospitalization, and Class III or IV heart failure. It is also contraindicated in patients with history of Mobitz type II second or third-degree atrioventricular (AV) block, sick sinus syndrome, or sino-atrial block, unless the patient has a functioning pacemaker. Advice from a cardiologist should be sought if treatment is being considered in patients with significant QT prolongation, arrhythmias requiring treatment with Class Ia or Class II anti-arrhythmic drugs or QT prolonging drugs, unstable ischemic heart disease, Class I or III heart failure, history of cardiac arrest, cerebrovascular disease, uncontrolled hypertension, resting heart rate less than 50 beats per minute, symptomatic bradycardia, recurrent cardiogenic syncope, severe untreated sleep apnea, history of Mobitz type I second degree AV block, unless the patient has a functioning pacemaker.
Heart Disease
Major:
etrasimod
Etrasimod has a major potential interaction with Heart Disease.
Etrasimod is contraindicated in patients who have experienced in the last 6 months myocardial infarction, unstable angina pectoris, stroke, transient ischemic attack, decompensated heart failure requiring hospitalization, and Class III or IV heart failure. It is also contraindicated in patients with history of Mobitz type II second or third-degree atrioventricular (AV) block, sick sinus syndrome, or sino-atrial block, unless the patient has a functioning pacemaker. Advice from a cardiologist should be sought if treatment is being considered in patients with significant QT prolongation, arrhythmias requiring treatment with Class Ia or Class II anti-arrhythmic drugs or QT prolonging drugs, unstable ischemic heart disease, Class I or III heart failure, history of cardiac arrest, cerebrovascular disease, uncontrolled hypertension, resting heart rate less than 50 beats per minute, symptomatic bradycardia, recurrent cardiogenic syncope, severe untreated sleep apnea, history of Mobitz type I second degree AV block, unless the patient has a functioning pacemaker.
Infection
Moderate:
etrasimod
Etrasimod has a moderate potential interaction with Infection.
Etrasimod increases the risk of infections as it decreases the peripheral lymphocyte counts. Treatment initiation should be delayed in patients with an active infection until the infection is resolved. Patients without a confirmed history of varicella (chickenpox), or without documentation of a full course of vaccination against varicella zoster virus, should be tested for antibodies before initiating treatment. Avoid the use of live attenuated vaccines during and for up to 5 weeks after treatment.
Liver Disease
Moderate:
etrasimod
Etrasimod has a moderate potential interaction with Liver Disease.
Elevations of transaminases have been reported in patients receiving etrasimod. Additionally, this drug undergoes extensive hepatic metabolism, and its exposure was found increased in subjects with severe hepatic dysfunction (Child-Pugh C). The use of etrasimod is not recommended on these patients. No dosage adjustment is needed in mild to moderate hepatic dysfunction.
Moderate:
palonosetron
Palonosetron has a moderate potential interaction with Liver Disease.
No dosage adjustment for palonosetron is necessary for patients with mild to moderate hepatic impairment (Child-Pugh score 5 to 8). Limited data are available in patients with severe hepatic impairment (Child-Pugh score greater than 9). It is recommended to avoid use of palonosetron in patients with severe hepatic impairment.
Renal Dysfunction
Moderate:
palonosetron
Palonosetron has a moderate potential interaction with Renal Dysfunction.
Mild to moderate renal impairment does not significantly affect palonosetron pharmacokinetic parameters. However, total systemic exposure increased approximately 28% in patients with severe renal impairment. Additionally, the pharmacokinetics of palonosetron have not been studied in patients with end-stage renal disease. Caution is advised.
Skin Cancer
Moderate:
etrasimod
Etrasimod has a moderate potential interaction with Skin Cancer.
Cases of malignancies, including skin malignancies have been reported in patients treated with some sphingosine -1-receptor (S1P) receptor modulators. Skin examinations are recommended prior and during treatment in all patients, particularly in those with risk factors for skin cancer. Suspicious skin lesions should be promptly evaluated, and patients at increased risk should wear protective clothing and use sunscreen with high protection factor.
Vaccination
Moderate:
etrasimod
Etrasimod has a moderate potential interaction with Vaccination.
Etrasimod increases the risk of infections as it decreases the peripheral lymphocyte counts. Treatment initiation should be delayed in patients with an active infection until the infection is resolved. Patients without a confirmed history of varicella (chickenpox), or without documentation of a full course of vaccination against varicella zoster virus, should be tested for antibodies before initiating treatment. Avoid the use of live attenuated vaccines during and for up to 5 weeks after treatment.
