Intermenstrual bleeding (spotting) has also been observed. The possibility of pregnancy should be considered if menstruation is delayed for >7 days of the expected menstrual period. In the treatment of uterine fibroids with Fibristal [Canadian product], a significant reduction in menstrual blood loss or amenorrhea is usually observed within 10 days of initiation; menses generally returns within 4 weeks after discontinuation. Endometrial thickening: Endometrial thickening has been observed with use of Fibristal [Canadian product] in the treatment of uterine fibroids; effects are reversible following discontinuation of therapy. Persistent endometrial thickening (>3 months after discontinuation of therapy and return of menses) should be further evaluated. Changes in endometrial tissue observed with use are referred to as progesterone receptor modulator-associated endometrial changes (PAEC); may be mistaken for endometrial hyperplasia. Pathologists should be informed of ulipristal therapy when submitting endometrial tissue for histologic evaluation. Disease related concerns: Asthma: Fibristal [Canadian product] is not recommended in patients with severe uncontrolled asthma. Special populations: Pediatric: Not for use prior to menarche. Postmenopausal women: Not indicated for use in postmenopausal women. Concurrent drug therapy issues: Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information. Other warnings/precautions: Appropriate use: Not intended for routine contraception. Repeated use within the same menstrual cycle is not recommended. Ectopic pregnancy: A history of ectopic pregnancy is not a contraindication to use in emergency contraception. The possibility of ectopic pregnancy should be considered in patients if pregnancy occurs after treatment or in patients with lower abdominal pain after administration of ulipristal. Fertility: A return of fertility is likely to be rapid following treatment of ulipristal for emergency contraception. Efficacy of hormonal contraception may be decreased; hormonal contraception should not be initiated until 5 days after emergency contraception and barrier contraception is recommended immediately following use of ulipristal; barrier contraception should be continued throughout the same menstrual cycle. Any nonhormonal contraceptive may be started immediately after uliprstal (Curtis 2016a). A nonhormonal method of contraception is recommended for women receiving Fibristal [Canadian product] for the treatment of uterine fibroids. HIV infection protection: Does not protect against HIV infection or other sexually-transmitted diseases. Pregnancy: Use is contraindicated in patients known or suspected to be pregnant. Exclude pregnancy prior to therapy via history, physical exam or pregnancy testing; not indicated for terminating an existing pregnancy. Monitoring Parameters Evaluate for pregnancy or ectopic pregnancy if expected menses is delayed for 1 week following emergency contraception, or if lower abdominal pain (3 to 5 weeks after administration) or persistent irregular bleeding develops. A pregnancy test is recommended if withdrawal bleeding does not occur within 3 weeks following use as an emergency contraceptive (Curtis 2015a). Fibristal [Canadian product]: Rule out pregnancy prior to therapy initiation; periodic monitoring of the endometrium; unexpected or persistent irregular bleeding Pregnancy Risk Factor X Pregnancy Considerations Adverse events have been observed in some animal reproduction studies. Exclude pregnancy prior to therapy; not indicated for terminating an existing pregnancy. A rapid return of fertility is expected following use for emergency contraception; routine contraceptive measures should be initiated or continued following use to ensure ongoing prevention of pregnancy. Barrier contraception is recommended immediately following emergency contraception and throughout the same menstrual cycle; efficacy of hormonal contraceptives may be decreased. The manufacturer labeling suggests that hormonal contraceptives may be less effective in females with BSA >30 kg/m 2 . When ulipristal is used for treatment of uterine fibroids (Canadian labeling; not in US labeling) a nonhormonal method of contraception is recommended. Health care providers are encouraged to enroll women who were exposed to ulipristal during the cycle pregnancy started or anytime during pregnancy in the Ellipse II study (forms available at www.ellipse2.com ). Patient Education Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?) Patient may experience headache, dizziness, loss of strength and energy, menstrual pain, menstrual irregularities, or hot flashes. Have patient report immediately to prescriber severe abdominal pain, abnormal vaginal bleeding, or groin or pelvic pain or edema (HCAHPS). Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions. Intended Use and Disclaimer: Should not be printed and given to patients.
