Contraindications

• Moderate or strong cytochrome P450 3A4 (CYP3A4) inhibitors
• Hepatic impairment
• Known hypersensitivity to ADDYI or any of its components. Reactions, including anaphylaxis, reactions consistent with angioedema, pruritus, and urticaria have been reported. 

Warnings and Precautions

• Hypotension and Syncope Due to an Interaction with Alcohol:  Taking ADDYI within two hours after consuming alcohol increases the risk of severe hypotension and syncope. To reduce this risk, counsel patients to wait at least two hours after drinking one or two standard alcoholic drinks before taking ADDYI at bedtime. Patients who drink three or more standard alcoholic drinks should skip their ADDYI dose that evening. After taking ADDYI at bedtime, advise patients to not use alcohol until the following day.
• Hypotension and Syncope with CYP3A4 Inhibitors: Moderate or strong CYP3A4 inhibitors significantly increase ADDYI concentrations, which can lead to hypotension and syncope. Concomitant use of ADDYI with a moderate or strong CYP3A4 inhibitor is contraindicated. Concomitant use of multiple weak CYP3A4 inhibitors that may include herbal supplements (e.g., ginkgo, resveratrol) or non-prescription drugs (e.g., cimetidine) could also lead to clinically relevant increases in flibanserin concentrations that may increase the risk of hypotension and syncope.
• Central Nervous System (CNS) Depression (e.g., Somnolence, Sedation):  Can occur with ADDYI alone and is exacerbated by other CNS depressants including alcohol, and in settings where flibanserin concentrations are increased such as CYP3A4 inhibitors. The risk of CNS depression is also increased if ADDYI is taken during waking hours. Patients should avoid activities requiring full alertness (e.g., operating machinery or driving) until at least six hours after each dose and until they know how ADDYI affects them.
• Hypotension and Syncope with ADDYI Alone:  The use of ADDYI – without other concomitant medications known to cause hypotension or syncope – can cause hypotension and syncope. The risk of hypotension and syncope is increased if ADDYI is taken during waking hours or if higher than the recommend dose is taken. Consider the benefits of ADDYI and the risks of hypotension and syncope in patients with pre-existing conditions that predispose to hypotension. Patients with pre-syncope should immediately lie supine and promptly seek medical help if symptoms do not resolve. Prompt medical attention should also be obtained for patients who experience syncope.
• Syncope and Hypotension in Patients with Hepatic Impairment: Any degree of hepatic impairment significantly increases flibanserin concentrations, which can lead to hypotension and syncope. ADDYI is contraindicated in patients with hepatic impairment.
• Hypersensitivity Reactions: Reactions including anaphylaxis, reactions consistent with angioedema, pruritus, and urticaria have been reported with ADDYI. Immediately discontinue ADDYI and initiate appropriate treatment if hypersensitivity reaction occurs. 

Drug Interactions

• Alcohol: coadministration of ADDYI with alcohol increased the risk of hypotension, syncope, and CNS depression compared to the use of ADDYI alone or alcohol alone. Patients should wait at least two hours after consuming one or two standard alcoholic drinks before taking ADDYI at bedtime or to skip their ADDYI dose if they have consumed three or more alcoholic drinks that evening.
• CNS Depressants: (i.e., diphenhydramine, opioids, hypnotics, benzodiazepines, etc.) Concomitant use with ADDYI may increase the risk of CNS depression compared to use of ADDYI alone.
• Moderate or Strong CYP3A4 Inhibitors: ADDYI is contraindicated in women taking moderate (e.g., fluconazole, etc.) or strong (e.g., ketoconazole, etc.) CYP3A4 inhibitors
• Oral Contraceptives and Other Weak CYP3A4 Inhibitors:  In combination with ADDYI may increase the risk of adverse reactions
• Strong CYP2C19 Inhibitors: (i.e., proton pump inhibitors, SSRI’s, benzodiazepines, antifungals, etc.) Increase flibanserin exposure which may increase risk of hypotension, syncope, and CNS depression
• CYP3A4 Inducers: (i.e., carbamazepine, phenobarbital, etc.) Concomitant use substantially decreases flibanserin exposure compared to the use of ADDYI alone and is not recommended.
• Digoxin or other P-glycoprotein (P-gp) substrates:  Increases digoxin concentration, which may lead to digoxin toxicity. Increase monitoring of drugs transported by P-gp that have a narrow therapeutic index.

Most Common Adverse Reactions

• Most common adverse reactions (ADDYI incidence ≥2% and higher than placebo) are dizziness, somnolence, nausea, fatigue, insomnia, and dry mouth.
