Food/lifestyle interactions
Major food/lifestyle interactions
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.

Disease interactions
12 potential interactions Applies to: 11 conditions, including Hypotension, Fever, Heart Disease, Diabetes Mellitus, and Syncope.
Alcoholism
Major:
flibanserin
Flibanserin has a major potential interaction with Alcoholism.
The use of flibanserin is contraindicated along with the ingestion of alcohol, as it increases the risk of hypotension and syncope. It is important to assess the likelihood of the patient abstaining from alcohol, taking into account the current and past drinking behavior.
Bleeding Disorder
Moderate:
dabrafenib
Dabrafenib has a moderate potential interaction with Bleeding Disorder.
The use of dabrafenib may increase the chance of hemorrhagic events. Care should be exercised when using this drug in patients who have had bleeding problems or who plan to have surgery, dental, or other medical procedures. Dabrafenib should be permanently discontinued for all grade 4 hemorrhagic events and for any grade 3 hemorrhagic events that do not improve. Dabrafenib should be withheld for grade 3 hemorrhagic events; if improved, this drug should resume at the next lower dose level.
Dermatitis, Drug-Induced
Moderate:
dabrafenib
Dabrafenib has a moderate potential interaction with Dermatitis, Drug-Induced.
The use of dabrafenib may result in severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome and drug reaction with eosinophilia and systemic symptoms (DRESS), which can be life-threatening or fatal. Care should be exercised when using this drug in patients at risk of skin toxicities. Patients should be monitored for new or worsening serious skin reactions. Dabrafenib should be permanently discontinued for SCARs. For other skin toxicities, dabrafenib should be withheld for intolerable or severe skin toxicity and should resume at a lower dose upon improvement or recovery within 3 weeks. Dabrafenib should be permanently discontinued if skin toxicity has not improved within 3 weeks.
Diabetes Mellitus
Moderate:
dabrafenib
Dabrafenib has a moderate potential interaction with Diabetes Mellitus.
In clinical trials, patients with a history of diabetes who received dabrafenib required more intensive hypoglycemic therapy. Care should be exercised when using this drug in patients with preexisting diabetes or hyperglycemia. Serum glucose levels should be monitored at the start of therapy and as clinically indicated in these patients. Antihyperglycemic medications should be started or optimized as clinically indicated.
Fever
Moderate:
dabrafenib
Dabrafenib has a moderate potential interaction with Fever.
Serious febrile reactions and fever of any severity complicated by rigors/chills, hypotension, dehydration, and/or renal failure have been observed with the use of dabrafenib. The incidence and severity of pyrexia are increased when this drug is administered in combination with trametinib compared with dabrafenib as a single agent. It is recommended to withhold therapy for temperature of 38C (100.4F) or higher; in case of recurrence, therapy can be interrupted at first symptom of pyrexia. Patients should be evaluated for signs/symptoms of infection, and it is recommended to monitor serum creatinine and other evidence of renal function during and after severe pyrexia. Antipyretics should be administered as secondary prophylaxis when resuming therapy for patients with prior episode of severe febrile reaction or fever associated with complications. Corticosteroids (e.g., prednisone 10 mg/day) should be administered for at least 5 days for second or subsequent pyrexia if temperature does not return to baseline within 3 days of pyrexia onset, or for pyrexia associated with complications, and there is no evidence of active infection. Upon resolution of pyrexia, dose reduction and/or permanent therapy discontinuation may be required.
G-6-PD Deficiency
Moderate:
dabrafenib
Dabrafenib has a moderate potential interaction with G-6-PD Deficiency.
Dabrafenib contains a sulfonamide moiety. Care should be exercised when using this drug in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency as it may increase the risk of hemolytic anemia. Patients with G6PD deficiency should be monitored for signs of hemolytic anemia while taking dabrafenib.
Heart Disease
Moderate:
dabrafenib
Dabrafenib has a moderate potential interaction with Heart Disease.
Cardiomyopathy (defined as a reduction in left ventricular ejection fraction [LVEF] at least 10% from baseline and below the institutional lower limit of normal [LLN]) has been reported with the use of dabrafenib in combination with trametinib. Caution should be exercised when using this drug in patients with heart problems. It is recommended to assess LVEF by echocardiogram or multigated acquisition (MUGA) scan before starting therapy, 1 month after starting, and then every 2 to 3 months while on treatment. Dabrafenib should be withheld for symptomatic cardiomyopathy or asymptomatic left ventricular dysfunction of greater than 20% from baseline that is below institutional LLN. Dabrafenib should resume at the same dose level upon recovery of cardiac function to at least the institutional LLN for LVEF and absolute decrease up to 10% compared to baseline.
Hypotension
Major:
flibanserin
Flibanserin has a major potential interaction with Hypotension.
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.
Infection
Moderate:
dabrafenib
Dabrafenib has a moderate potential interaction with Infection.
Serious febrile reactions and fever of any severity complicated by rigors/chills, hypotension, dehydration, and/or renal failure have been observed with the use of dabrafenib. The incidence and severity of pyrexia are increased when this drug is administered in combination with trametinib compared with dabrafenib as a single agent. It is recommended to withhold therapy for temperature of 38C (100.4F) or higher; in case of recurrence, therapy can be interrupted at first symptom of pyrexia. Patients should be evaluated for signs/symptoms of infection, and it is recommended to monitor serum creatinine and other evidence of renal function during and after severe pyrexia. Antipyretics should be administered as secondary prophylaxis when resuming therapy for patients with prior episode of severe febrile reaction or fever associated with complications. Corticosteroids (e.g., prednisone 10 mg/day) should be administered for at least 5 days for second or subsequent pyrexia if temperature does not return to baseline within 3 days of pyrexia onset, or for pyrexia associated with complications, and there is no evidence of active infection. Upon resolution of pyrexia, dose reduction and/or permanent therapy discontinuation may be required.
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:
dabrafenib
Dabrafenib has a moderate potential interaction with Liver Disease.
Hepatic metabolism and biliary secretion are the primary routes of elimination of dabrafenib and its metabolites; thus, patients with moderate (bilirubin greater than 1.5 to 3 times the upper limit of normal [1.5 to 3 x ULN] and any AST) or severe (bilirubin greater than 3 to 10 x ULN and any AST) liver dysfunction may have increased exposure. An appropriate dosage has not been established for patients with moderate or severe liver dysfunction; care should be exercised when using dabrafenib in these patients. Dose adjustment is not recommended for patients with mild liver dysfunction (bilirubin up to ULN and AST greater than ULN or bilirubin greater than 1 to 1.5 x ULN and any AST).
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.
