Disease interactions

5 potential interactions Applies to: 4 conditions, including Hypotension, Syncope, Liver Disease, and Alcoholism.

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.

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:

bicalutamide

Bicalutamide has a moderate potential interaction with Liver Disease.

Bicalutamide is extensively metabolized by the liver and its metabolism may be altered and/or delayed in patients with moderate to severe hepatic impairment. Therapy with bicalutamide should be administered cautiously in patients with moderate to severe hepatic impairment. Additionally there have been postmarketing reports of death or hospitalization due to severe liver injury (hepatic failure) in association with bicalutamide, so extra caution is advised in patients with hepatic impairment. Patients should be instructed to immediately report any sign or symptoms of hepatic dysfunction such as jaundice, dark urine, right upper quadrant pain, or anorexia. Clinical monitoring of hepatic function is recommended. Although hepatic abnormalities such as elevated liver transaminase levels and jaundice are usually reversible, bicalutamide therapy should be discontinued if transaminase levels exceed two times the upper normal limits.

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.
