Drug interactions

Moderate drug interactions

Moderate:

flibanserin rucaparib

Applies to: flibanserin and rucaparib

Rucaparib may increase the blood levels of flibanserin.

In some cases, this may increase the risk of side effects such as 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, or you may need a dose adjustment or 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.

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.

Disease interactions

7 potential interactions Applies to: 6 conditions, including Hypotension, Syncope, Liver Disease, Alcoholism, and Renal Dysfunction.

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.

Bone Marrow Depression/Low Blood Counts

Moderate:

rucaparib

Rucaparib has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.

Cases of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) have been reported with the use of rucaparib. Rucaparib should not be started until patients have recovered from hematological toxicity caused by previous chemotherapy (grade 1 or less). It is recommended to monitor complete blood counts for cytopenia at baseline and monthly thereafter for clinically significant changes during therapy. For hematologic toxicities exceeding 4 weeks, rucaparib should be interrupted or the dosage reduced according to the manufacturer product information; blood counts should be monitored weekly until recovery. If levels have not recovered to grade 1 or less after 4 weeks or if MDS/AML is suspected, the patient should be referred to a hematologist for further investigations (including bone marrow analysis and blood sample for cytogenetics). If MDS/AML is confirmed, rucaparib should be discontinued.

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.

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:

rucaparib

Rucaparib has a moderate potential interaction with Liver Disease.

No dose adjustment is recommended for patients with mild to moderate liver dysfunction (total bilirubin up to 3 times the upper limit of normal [3 x ULN] or AST greater than ULN). Caution should be exercised when using this agent in patients with severe liver dysfunction (total bilirubin greater than 3 x ULN and any AST) as rucaparib has not been studied in these patients.

Renal Dysfunction

Moderate:

rucaparib

Rucaparib has a moderate potential interaction with Renal Dysfunction.

No dose adjustment is recommended for patients with mild to moderate renal dysfunction (CrCl between 30 and 89 mL/min [as estimated by Cockcroft-Gault method]). Caution should be exercised when using this agent in patients with severe renal dysfunction (CrCl less than 30 mL/min) or patients on dialysis as rucaparib has not been studied in these patients.

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.
