Treatment of premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD) that is characterized by low sexual desire that causes marked distress or interpersonal difficulty and is NOT due to a concomitant medical or psychiatric condition, relationship problems, or the effects of a medication or drug substance.

Assess sexual desire prior to and periodically during therapy.
Assess cardiovascular risk and control of BP periodically during therapy. Systolic BP ↑ 6 mmHg, diastolic BP ↑ 3 mmHg and HR ↓ up to 5 bpm transiently after dose; usually return to normal within 12 hr of dose.
Assess for focal hyperpigmentation of face, gingiva, and breasts periodically during therapy. More common in patients with dark skin or with >8 doses/month. Consider discontinuation of therapy if hyperpigmentation occurs; may not resolve with discontinuation.
Assess for nausea during therapy; may require antiemetics. Usually improves with 2nd dose; may require discontinuation.
Subcut Using auto-injector, inject into abdomen or thigh 45 min before anticipated sexual activity. Do not administer more than 1 dose/24 hr or more than 8 doses/month.
Instruct patient to take medication as directed with no more than 1 dose/24 hr or no more than 8 doses/month. Advise patient to read Patient Information before starting and with each Rx refill in case of changes.
Inform patient that increases in BP and decreases in HR may occur after each dose; usually resolve within 12 hr.
Inform patient that darkening of the skin of the face, gums, and breasts may occur, especially in patients with darker skin. Risks increase with daily use. Advise patient that changes may not resolve after stopping the medication. Contact health care professional for concerns about skin changes.
Inform patient that nausea may occur, especially after first dose, lasting 2 or more hr. May require antiemetics. Advise patient to notify health care professional if nausea is problematic.
Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications.
Rep: Advise women of reproductive potential use effective contraception during therapy and to notify health care professional if pregnancy is planned or expected or if breastfeeding.
