Drug interactions
Moderate drug interactions
Moderate:
felbamate fidanacogene elaparvovec
Applies to: felbamate and Beqvez (fidanacogene elaparvovec)
Fidanacogene elaparvovec can cause liver problems, which may make the medication less effective in treating your condition. Using other medications that can also affect the liver such as felbamate after receiving fidanacogene elaparvovec may increase that risk. Symptoms of liver problems include fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark urine, pale stools, and/or yellowing of the skin or eyes. Blood tests to monitor liver function should be performed before and after treatment with fidanacogene elaparvovec. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need more frequent monitoring to safely use both medications. 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

Disease interactions
14 potential interactions Applies to: 12 conditions, including Depression, Anemia, HIV-1 Infection, Psychosis, and Liver Disease.
Alcoholic Cirrhosis
Moderate:
Beqvez
The fidanacogene elaparvovec in Beqvez has a moderate potential interaction with Alcoholic Cirrhosis.
Fidanacogene elaparvovec, a liver-targeting gene therapy, may carry the theoretical risk of hepatocellular carcinoma development. Patients with risk factors for hepatocellular carcinoma (e.g., hepatitis B or C, non-alcoholic fatty liver disease, chronic alcohol consumption, non-alcoholic steatohepatitis, advanced age) should be monitored with regular liver ultrasound (e.g., annually) and alpha-fetoprotein testing for 5 years following treatment.
Alcoholic Liver Damage
Moderate:
Beqvez
The fidanacogene elaparvovec in Beqvez has a moderate potential interaction with Alcoholic Liver Damage.
Fidanacogene elaparvovec, a liver-targeting gene therapy, may carry the theoretical risk of hepatocellular carcinoma development. Patients with risk factors for hepatocellular carcinoma (e.g., hepatitis B or C, non-alcoholic fatty liver disease, chronic alcohol consumption, non-alcoholic steatohepatitis, advanced age) should be monitored with regular liver ultrasound (e.g., annually) and alpha-fetoprotein testing for 5 years following treatment.
Alcoholism
Moderate:
Beqvez
The fidanacogene elaparvovec in Beqvez has a moderate potential interaction with Alcoholism.
Fidanacogene elaparvovec, a liver-targeting gene therapy, may carry the theoretical risk of hepatocellular carcinoma development. Patients with risk factors for hepatocellular carcinoma (e.g., hepatitis B or C, non-alcoholic fatty liver disease, chronic alcohol consumption, non-alcoholic steatohepatitis, advanced age) should be monitored with regular liver ultrasound (e.g., annually) and alpha-fetoprotein testing for 5 years following treatment.
Anemia
Major:
felbamate
Felbamate has a major potential interaction with Anemia.
The use of felbamate is contraindicated in patients with bone marrow suppression or a current or prior history of blood dyscrasias. A marked increase in the incidence of aplastic anemia has been associated with the use of felbamate, reportedly exceeding 100 times the incidence observed in the general population (2 to 5 per million persons per year). In the few cases that have been reported in felbamate patients, the onset of clinical manifestations of aplastic anemia ranged from 5 to 30 weeks. However, the injury to bone marrow stem cells that is believed to be ultimately responsible for the anemia may occur much earlier. Currently, it is not known whether the risk is related to dose, duration of exposure, and/or concomitant use of other antiepileptic or myelotoxic drugs. Expert hematologic consultation should be available for all patients treated with felbamate. Since aplastic anemia typically develops without premonitory clinical or laboratory signs, it should be borne in mind that routine blood testing may not be reliably used to prevent development of the syndrome. However, in some cases, it may allow the detection of hematologic changes before the condition is full-blown. Felbamate therapy should be withdrawn if evidence of bone marrow depression is observed. Patients who are discontinued from the drug may remain at risk for developing anemia for a variable and unknown period afterwards and should be monitored accordingly.
Bone Marrow Depression/Low Blood Counts
Major:
felbamate
Felbamate has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
The use of felbamate is contraindicated in patients with bone marrow suppression or a current or prior history of blood dyscrasias. A marked increase in the incidence of aplastic anemia has been associated with the use of felbamate, reportedly exceeding 100 times the incidence observed in the general population (2 to 5 per million persons per year).

Patients who are discontinued from the drug may remain at risk for developing anemia for a variable and unknown period afterwards and should be monitored accordingly.
Depression
Moderate:
felbamate
Felbamate has a moderate potential interaction with Depression.
Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.
History of Blood Dyscrasias
Major:
felbamate
Felbamate has a major potential interaction with History of Blood Dyscrasias.
The use of felbamate is contraindicated in patients with bone marrow suppression or a current or prior history of blood dyscrasias. A marked increase in the incidence of aplastic anemia has been associated with the use of felbamate, reportedly exceeding 100 times the incidence observed in the general population (2 to 5 per million persons per year).

HIV-1 Infection
Moderate:
Beqvez
The fidanacogene elaparvovec in Beqvez has a moderate potential interaction with HIV-1 Infection.
There is limited information on the safety and effectiveness of fidanacogene elaparvovec in patients with HIV infection. Perform HIV testing prior to infusion, and do not administer this product to patients with either CD4+ cell count less than 200 mm3 or viral load equal to or greater than 20 copies/mL in case of serological evidence of HIV-1 or HIV-2 infection.
Infectious Hepatitis
Moderate:
Beqvez
The fidanacogene elaparvovec in Beqvez has a moderate potential interaction with Infectious Hepatitis.
Fidanacogene elaparvovec, a liver-targeting gene therapy, may carry the theoretical risk of hepatocellular carcinoma development. Patients with risk factors for hepatocellular carcinoma (e.g., hepatitis B or C, non-alcoholic fatty liver disease, chronic alcohol consumption, non-alcoholic steatohepatitis, advanced age) should be monitored with regular liver ultrasound (e.g., annually) and alpha-fetoprotein testing for 5 years following treatment.
Liver Disease
Major:
felbamate
Felbamate has a major potential interaction with Liver Disease.
The use of felbamate is contraindicated in patients with a history of hepatic impairment. A marked increase in the incidence of hepatic failure, some resulting in fatality, has been associated with the use of felbamate relative to that expected in the general population (approximately 2000 cases per year). Currently, it is not known whether the risk is related to dose, duration of exposure, and/or concomitant use of other antiepileptic or hepatotoxic drugs. All patients treated with felbamate should have serum transaminase and bilirubin levels checked prior to initiating therapy and at 1- to 2-week intervals while treatment continues. Felbamate therapy should be withdrawn if abnormal liver function tests occur.
Moderate:
Beqvez
The fidanacogene elaparvovec in Beqvez has a moderate potential interaction with Liver Disease.
Fidanacogene elaparvovec has not been studied in patients with liver dysfunction. Furthermore, administration of this product can lead to liver transaminase elevations and hepatocyte injury. Patients should undergo a liver health assessment prior to treatment, which includes liver function tests, screening for active hepatitis B or C, and elastography and/or ultrasound to assess liver fibrosis. This product should not be administered to patients with current liver-related coagulopathy, hypoalbuminemia, persistent jaundice, or cirrhosis, portal hypertension, splenomegaly, hepatic encephalopathy, hepatic fibrosis, or active viral hepatitis.
Psychosis
Moderate:
felbamate
Felbamate has a moderate potential interaction with Psychosis.
Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.
Renal Dysfunction
Major:
felbamate
Felbamate has a major potential interaction with Renal Dysfunction.
Felbamate is partially eliminated by the kidney as unchanged drug (approximately 40% to 50% of absorbed dose). The plasma clearance of felbamate may be decreased and the half-life prolonged in patients with impaired renal function. Therapy with felbamate should be administered cautiously in patients with renal impairment.
Moderate:
Beqvez
The fidanacogene elaparvovec in Beqvez has a moderate potential interaction with Renal Dysfunction.
Fidanacogene elaparvovec has not been studied in patients with renal dysfunction.
