Is her sexual desire diminished?

Is it causing her distress?

Ask her!1

PrADDYI® (flibanserin) is indicated for the treatment of premenopausal and naturally postmenopausal women ≤ 60 years of age with acquired, generalized hypoactive sexual desire disorder (HSDD), as characterized by low sexual desire for a minimum of 6 months, which occurs 75-100% of the time, that causes marked distress or interpersonal difficulty and is NOT due to:2

  • a co-existing medical or psychiatric condition,
  • problems within the relationship, or
  • the effects of a medication or other drug substance.

“Acquired”: HSDD in patients who previously had no problem with sexual desire.

“Generalized”: HSDD that occurs regardless of the type of stimulation, situation or partner.

Limitations of use2

  • ADDYI is not indicated for use in men.
  • ADDYI is not indicated to enhance sexual performance.

ADDYI is the FIRST and ONLY medication indicated for acquired, generalized HSDD in pre and naturally postmenopausal women ≤60 years of age in Canada3*

HSDD is a condition that has been medically recognized for nearly half a century. It is the most common form of female sexual dysfunction, but frequently undiagnosed.1

For more information about HSDD history, diagnosis and treatment, please refer to the (SOGC) Female Sexual Health Consensus Clinical Guidelines.4

The Conversation Begins With a Validated Screener

As her healthcare provider, it’s important for you to lead the dialogue relating to her concerns about her hypoactive sexual desire. Screening for HSDD can be done in a timely way using the Decreased Sexual Desire Screener (DSDS). This is a validated medical questionnaire with just 5 questions.5

Once the diagnosis has been established, and the patient has expressed a desire for treatment, it is important to evaluate whether ADDYI is suitable for the patient. The Prescriber’s Checklist facilitates this. The pharmacy can confirm the patient’s eligibility for treatment by using The Pharmacist’s Checklist.

Adverse Reactions2

Most common adverse reactions occurring in ADDYI clinical studies in premenopausal women

Placebo (n=1,905) ADDYI (n=1,543)
Dizziness 2.2% 11.4%
Somnolence 3.1% 11.2%
Nausea 3.7% 10.4%
Fatigue 5.0% 9.2%

Adapted from the ADDYI product monograph.2

The majority of these adverse reactions emerged in the first 14 days of treatment and were of mild to moderate intensity.

In five 24-week, double-blind, placebo-controlled, randomized studies (including the 3 studies above), the discontinuation rate due to adverse reactions was 13% among patients taking ADDYI vs. 6% among patients taking placebo. The adverse reactions most commonly causing discontinuation of ADDYI were dizziness (1.7%), nausea (1.2%), insomnia (1.1%), somnolence (1.1%), anxiety (1.0%) and fatigue (0.9%). Serious adverse reactions were reported in 0.8% of ADDYI-treated patients and 0.5% of placebo-treated patients.

Most common adverse reactions occurring in ADDYI clinical studies in postmenopausal women

Placebo (n=849) ADDYI (n=843)
Dizziness 3.3% 8.4%
Somnolence 1.8% 7.9%
Nausea 3.8% 6.5%
Insomnia 3.3% 6.4%
Headache 5.5% 5.7%

Adapted from the ADDYI product monograph.2

The majority of these adverse reactions emerged in the first 4 weeks of treatment and were of mild to moderate intensity.

In two double-blind, placebo-controlled, randomized studies, the discontinuation rate due to adverse events in patients treated with ADDYI (n=843) was 9.1% compared to 5.2% in placebo-treated patients (n=849). The adverse events most commonly causing discontinuation of ADDYI were insomnia (1.5%), and anxiety (1.2%). Serious adverse events were reported in 1.4% of ADDYI-treated patients and 0.8% of placebo-treated patients.

Dosing2

ADDYI comes in the form of a 100 mg pill. The recommended dose is 100 mg, taken orally, once daily at bedtime.

Bedtime dosing is important. ADDYI taken at a time other than bedtime can increase the risk of hypotension, syncope, and CNS depression (such as somnolence and sedation). If a dose of ADDYI is missed at bedtime, instruct the patient to take the next dose at bedtime on the next day, and not to double the next dose.

Discontinue treatment after 8 weeks if the patient does not report an improvement in sexual desire and/or a reduction in associated distress.

Using ADDYI before or after moderate or strong CYP3A4 inhibitors:

  • Start the moderate or strong CYP3A4 inhibitor 2 days after the last dose of ADDYI. When the benefit of initiating a moderate or strong CYP3A4 inhibitor within 2 days of stopping ADDYI clearly outweighs the risk of flibanserin exposure-related severe hypotension and syncope, carefully monitor the patient for signs of hypotension and syncope.
  • Start ADDYI 2 weeks after the last dose of the CYP3A4 inhibitor.

Please see the Product Monograph for complete dosing and administration instructions.

Overdosing2

Overdosage may cause an increase in incidence or severity of any of the reported adverse reactions. Acute overdosage has also been associated with seizure-like activity, hypertension, unresponsiveness to pain, mydriasis, slurred speech and fever.

Treatment should address the symptoms and supportive measures as needed. There is no known antidote specific for flibanserin.

IMPORTANT SAFETY INFORMATION

Clinical use:
Special diagnostic considerations

  • There is no normative age- or gender-related data on frequency or degree of sexual desire. Therefore, the diagnosis must rely on clinical judgment based on the individual’s characteristics, interpersonal determinants, life context and cultural settings.
  • The clinician may need to assess both partners when discrepancies in sexual desire prompt the call for professional attention.
  • When making the diagnosis, it is recommended to use the ADDYI Prescriber’s Checklist.

The safety and efficacy of ADDYI have not been established in patients >55 or <18 years of age.

Contraindications:

  • Patients taking a moderate or strong CYP3A4 inhibitor (e.g. ketoconazole, itraconazole, fluconazole, ritonavir, or clarithromycin)
  • Patients with hepatic impairment
  • Patients who are pregnant or breastfeeding
  • Patients with resting systolic blood pressure <110 mmHg or diastolic blood pressure <60 mmHg and who are using alcohol

Most serious warnings and precautions:

Use of ADDYI and alcohol can cause severe hypotension and syncope. Patients taking ADDYI should do so at bedtime and immediately lie supine if they feel they are about to pass out. The use of ADDYI and alcohol together close in time increases the risk of severe hypotension and syncope.

ADDYI can cause CNS depression (e.g., somnolence, sedation). Patients should not drive or engage in other activities requiring full alertness after taking ADDYI until they know how ADDYI affects them. The concomitant use of ADDYI with CNS depressants may increase the risk of CNS depression (e.g., somnolence) compared to the use of ADDYI alone.

The concomitant use of ADDYI with moderate or strong inhibitors of CYP3A4 or in patients with hepatic impairment causes a significant increase of flibanserin concentration which may be associated with severe hypotension and syncope.

Other relevant warnings and precautions:

  • Hypotension and syncope
  • Tachycardia and palpitations
  • Increase monitoring for adverse reactions in patients who are CYP2C19 poor metabolizers
  • Concomitant use of multiple weak CYP3A4 inhibitors
  • Central nervous system depression
  • Use in patients taking antidepressants
