Drug interactions
Major drug interactions
Major:
crizotinib flibanserin
Applies to: crizotinib and flibanserin
Using flibanserin together with crizotinib is not recommended.
Combining these medications can significantly increase the blood levels of flibanserin, which may cause excessive drowsiness and decreases in blood pressure that can lead to:
- dizziness
- lightheadedness
- fainting
- accidental injury
You should take flibanserin at bedtime to minimize the risk of these effects.
Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact.
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
Major food/lifestyle interactions
Major:
crizotinib Food/Lifestyle
Applies to: crizotinib
Do not consume grapefruit or grapefruit juice during treatment with crizotinib unless directed otherwise by your doctor.
Grapefruit juice can increase the blood levels of crizotinib to dangerous levels and cause an irregular heart rhythm that may be serious.
You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or fast or pounding heartbeats during treatment with crizotinib.
You may take crizotinib with or without food, but take it the same time each day.
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.
Major:
flibanserin Food/Lifestyle
Applies to: flibanserin
Do not use alcohol too close to the dosing time of flibanserin. Doing so can cause excessive drowsiness and decreases in blood pressure, which may lead to:
- dizziness
- lightheadedness
- fainting
- accidental injury
What to do: Take flibanserin at bedtime to minimize the risk of these effects. It is recommended that you stop drinking alcohol at least two hours before taking flibanserin; otherwise, you should just skip the flibanserin dose that evening. Alcohol should not be consumed until at least the morning after taking flibanserin at bedtime.
Because grapefruit juice can significantly increase the blood levels of flibanserin, you should also avoid the consumption of grapefruit and grapefruit juice during treatment.
Talk to your healthcare provider 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.

Severe, life-threatening, or fatal interstitial lung disease (ILD)/pneumonitis can occur with crizotinib. Care should be exercised when using this drug in patients with preexisting pulmonary impairment. Patients should be monitored for pulmonary symptoms indicative of ILD/pneumonitis. Crizotinib should be permanently discontinued in patients diagnosed with drug-related ILD/pneumonitis if no other potential causes of ILD/pneumonitis have been identified.
Liver Disease
Major:
flibanserin
Flibanserin has a major potential interaction with Liver Disease.
Flibanserin may accumulate in patients with hepatic impairment. Therapy with flibanserin is contraindicated in patients with compromised hepatic function.
Moderate:
crizotinib
Crizotinib has a moderate potential interaction with Liver Disease.
Crizotinib concentrations increased in patients with preexisting moderate (any AST and total bilirubin greater than 1.5 to 3 times the upper limit of normal [1.5 to 3 x ULN]) or severe (any AST and total bilirubin greater than 3 x ULN) liver dysfunction; a reduced dosage of crizotinib is recommended in these patients. Caution is recommended in patients with moderate or severe liver dysfunction. No dose adjustment is recommended in patients with preexisting mild liver dysfunction (AST greater than ULN and total bilirubin up to 1 x ULN or any AST and total bilirubin greater than 1 to 1.5 x ULN).
Cases of drug-induced hepatotoxicity with fatal outcomes have been reported with the use of crizotinib. It is recommended to monitor liver function tests (including ALT, AST, total bilirubin) every 2 weeks during the first 2 months of therapy, then once a month, and as clinically indicated, with more frequent repeat testing for increased liver transaminases, alkaline phosphatase, or total bilirubin in patients who develop increased transaminases. It is recommended to withhold, reduce dose, or permanently discontinue crizotinib for hepatotoxicity as recommended.
Pulmonary Impairment
Moderate:
crizotinib
Crizotinib has a moderate potential interaction with Pulmonary Impairment.
Severe, life-threatening, or fatal interstitial lung disease (ILD)/pneumonitis can occur with crizotinib. Care should be exercised when using this drug in patients with preexisting pulmonary impairment. Patients should be monitored for pulmonary symptoms indicative of ILD/pneumonitis. Crizotinib should be permanently discontinued in patients diagnosed with drug-related ILD/pneumonitis if no other potential causes of ILD/pneumonitis have been identified.
Renal Dysfunction
Moderate:
crizotinib
Crizotinib has a moderate potential interaction with Renal Dysfunction.
The exposure to crizotinib is increased in patients with preexisting severe renal dysfunction (CrCl less than 30 mL/min [calculated using the modified Cockcroft-Gault equation for adult patients and the Schwartz equation for pediatric patients]) not requiring dialysis; a reduced dosage of crizotinib is recommended in these patients. Care should be exercised when using this drug in patients with severe renal dysfunction not requiring dialysis. No dose adjustment is recommended in patients with mild to moderate renal dysfunction (CrCl 30 to 89 mL/min).
Syncope
Major:
flibanserin
Flibanserin has a major potential interaction with Syncope.
The use of flibanserin can cause hypotension and syncope. The benefits and risks of therapy should be considered in patients with preexisting conditions that predispose to hypotension. Flibanserin should be used with caution in these patients.
Visual Defect/Disturbance
Moderate:
crizotinib
Crizotinib has a moderate potential interaction with Visual Defect/Disturbance.
Cases of optic atrophy and optic nerve disorder leading to vision loss have been reported with the use of crizotinib. Assessment of visual symptoms for all patients is recommended monthly during therapy; new visual symptoms should be reported to an eye specialist. For pediatric and young adult patients with anaplastic large cell lymphoma or inflammatory myofibroblastic tumor, baseline and follow-up ophthalmologic examinations (including retinal examination) should be obtained within 1 month of starting crizotinib and every 3 months thereafter. The ophthalmological evaluation should consist of best corrected visual acuity, retinal photographs, visual fields, optical coherence tomography (OCT), and other evaluations as appropriate. Crizotinib should be permanently discontinued for grade 3 or 4 ocular disorders or severe visual loss (best corrected vision less than 20/200 in 1 or both eyes) unless another cause is identified. There is insufficient information to characterize the risks of resumption of crizotinib in patients who develop visual symptoms or visual loss; a decision to resume treatment with crizotinib should consider the potential benefits versus risks to the patient.
