WARNINGS AND PRECAUTIONS Cystitis and Pyelonephritis: Avoid use in women with a history of recurrent UTI or urinary tract abnormalities ( 5.1 ) 5.1 Cystitis and Pyelonephritis Among 2804 subjects who received PHEXXI in Studies 1 and 2, 0.36% (n=10) reported adverse reactions of cystitis, pyelonephritis, or other upper urinary tract infection (UTI). Of these, one case of pyelonephritis was considered serious and required hospitalization. Avoid use of PHEXXI in females of reproductive potential with a history of recurrent urinary tract infection or urinary tract abnormalities .

ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Cystitis and Pyelonephritis [see Warnings and Precautions (5.1) ] Most common adverse reactions (≥2%) were vulvovaginal burning sensation, vulvovaginal pruritus, vulvovaginal mycotic infection, urinary tract infection, vulvovaginal discomfort, bacterial vaginosis, vaginal discharge, genital discomfort, dysuria, and vulvovaginal pain.

The safety of PHEXXI (pre-filled applicator with 5-gram dose) has been evaluated in two clinical trials (Study 1 and Study 2) in 2804 subjects (over 19,000 cycles of exposure) . The racial/ethnic distribution was 66% White, 27% Black or African American, 2% Asian, 1% American Indian or Alaska Native, 0.3% Native Hawaiian or Pacific Islander, and 5% other; 32% of the study population was Hispanic. Study 1 included a one-year extension phase where 342 U.S. subjects were exposed to PHEXXI for 13 cycles. Hypersensitivity Reaction Of the 2804 PHEXXI-treated subjects in Studies 1 and 2, one subject reported a suspected drug hypersensitivity. Avoid PHEXXI use in females of reproductive potential with suspected hypersensitivity to the ingredients in PHEXXI. The most common adverse reactions (≥10%) in the U.S. population in Studies 1 and 2 (n = 2480) were: vulvovaginal burning sensation (18.0%) and vulvovaginal pruritus (14.5%). The majority of these adverse reactions were mild and few led to discontinuation. Table 1 summarizes the most common adverse reactions (≥2%) reported by subjects using PHEXXI in the U.S. Table 1. Adverse Reactions that Occurred in ≥ 2% of Subjects Who Used PHEXXI to Prevent Pregnancy (Studies 1 and 2 – U.S. population only) Adverse Reaction PHEXXI (N=2480) (%) Vulvovaginal Burning Sensation 18.0 Vulvovaginal Pruritus 14.5 Vulvovaginal Mycotic Infection Includes preferred terms (PT) vulvovaginal mycotic infection and vulvovaginal candidiasis. 9.1 Urinary Tract Infection Includes PTs urinary tract infection, streptococcal urinary tract infection, Escherichia urinary tract infection, and urinary tract infection bacterial. Does not include PTs cystitis, kidney infection, and pyelonephritis [see Warnings and Precautions (5.1)]. 9.0 Vulvovaginal Discomfort 9.0 Bacterial Vaginosis 8.4 Vaginal Discharge 5.5 Genital Discomfort 4.1 Dysuria 3.1 Vulvovaginal pain 2.1 Among subjects who used PHEXXI in Studies 1 and 2, 1.6% discontinued from the clinical trials due to an adverse reaction. The most common adverse reactions leading to study discontinuation were vulvovaginal burning sensation (0.7%); and vulvovaginal pruritus and vulvovaginal discomfort (0.1% each). Adverse Reactions in Male Partners Among male partners of subjects who used PHEXXI for contraception in Study 2, 9.8% (131 of 1330) reported symptoms of local discomfort (burning, itching, pain, and "other"). Of these local discomfort symptoms, 74.7% were mild, 21.4% were moderate, and 3.9% were severe. Two subjects discontinued participation in the study due to male partner symptoms.
