Moderate drug interactions

Moderate:

clopidogrel enzalutamide

Applies to: clopidogrel and enzalutamide

Talk to your doctor before using enzalutamide together with clopidogrel. Combining these medications can significantly increase the blood levels and effects of enzalutamide.

This may increase the risk and/or severity of side effects such:

  • seizure
  • tiredness
  • weakness
  • diarrhea
  • muscle or bone pain
  • hot flushes
  • swelling
  • tingling or prickling sensation
  • headache
  • dizziness
  • insomnia
  • anxiety
  • high blood pressure

You may need a dose adjustment or more frequent monitoring by your doctor 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

No alcohol/food interactions were found. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.

Disease interactions

9 potential interactions Applies to: 8 conditions, including Seizures, Head Injury, Liver Disease, Bleeding Disorder, and Brain Tumor.

Bleeding Disorder

Major:

clopidogrel

Clopidogrel has a major potential interaction with Bleeding Disorder.

Clopidogrel is contraindicated in patients with active pathological bleeding such as peptic ulcer or intracranial hemorrhage.

Brain Tumor

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with Brain Tumor.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

CNS Infection

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with CNS Infection.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

Head Injury

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with Head Injury.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

History - Cerebrovascular Disease

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with History - Cerebrovascular Disease.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

Liver Disease

Moderate:

clopidogrel

Clopidogrel has a moderate potential interaction with Liver Disease.

The pharmacokinetic disposition of clopidogrel in patients with liver disease has not been established. Clopidogrel undergoes biotransformation to an active metabolite that has not yet been isolated and an inactive form that represents approximately 85% of circulating clopidogrel. The metabolic and therapeutic activity of clopidogrel may be altered in patients with hepatic impairment and should be administered cautiously in patients with severe hepatic dysfunction. Clinical monitoring of hepatic function and bleeding activity is recommended.

Renal Dysfunction

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with Renal Dysfunction.

Enzalutamide has not been assessed in patients with severe renal impairment or end-stage renal disease. Caution is advised if used on these patients. No initial dosage adjustment is required on patients with mild to moderate renal impairment.

Minor:

clopidogrel

Clopidogrel has a minor potential interaction with Renal Dysfunction.

Clopidogrel is partially eliminated by the kidney. Approximately 50% of clopidogrel is excreted in the urine and 45% in the feces. Plasma concentrations of the inactive metabolite and the degree of platelet inhibition are reduced in patients with severe renal impairment (creatinine clearance of 5-15 mL/min). However, bleeding times in patients with severe renal impairment did not differ from those with normal renal function. No dosage adjustment is recommended for patients with compromised renal function.

Seizures

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with Seizures.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
