ELLA- ulipristal acetate tablet
RPK Pharmaceuticals, Inc.
ella is a progesterone agonist/antagonist emergency contraceptive indicated for prevention of pregnancy following unprotected intercourse or a known or suspected contraceptive failure. ella is not intended for routine use as a contraceptive.
Instruct patients to take one tablet orally as soon as possible within 120 hours (5 days) after unprotected intercourse or a known or suspected contraceptive failure.
The tablet can be taken with or without food.
If vomiting occurs within 3 hours of ella intake, consideration should be given to repeating the dose.
ella can be taken at any time during the menstrual cycle.
The ella tablet is supplied as a white to off-white, round, curved tablet containing 30 mg of ulipristal acetate and is marked “ella ” on both sides.
ella is contraindicated for use in the case of known or suspected pregnancy. [See Use in Specific Populations (8.1).]
ella is not indicated for termination of an existing pregnancy
A history of ectopic pregnancy is not a contraindication to use of this emergency contraceptive method. Healthcare providers, however, should consider the possibility of ectopic pregnancy in women who become pregnant or complain of lower abdominal pain after taking ella. A follow-up physical or pelvic examination is recommended if there is any doubt concerning the general health or pregnancy status of any woman after taking ella.
ella is for occasional use as an emergency contraceptive. It should not replace a regular method of contraception. Repeated use of ella within the same menstrual cycle is not recommended, as safety and efficacy of repeat use within the same cycle has not been evaluated.
A CYP3A4 inducer, rifampin, decreases the plasma concentration of ella significantly. ella should not be administered with CYP3A4 inducers [see Drug interactions (7.1) and Clinical Pharmacology (12.3)].
A rapid return of fertility is likely following treatment with ella for emergency contraception.
After use of ella , a reliable barrier method of contraception should be used with subsequent acts of intercourse that occur in that same menstrual cycle.Because ella and the progestin component of hormonal contraceptives both bind to the progesterone receptor, using them together could reduce their contraceptive effect. After using ella , if a woman wishes to use hormonal contraception, she should do so no sooner than 5 days after the intake of ella , and she should use a reliable barrier method until the next menstrual period [see Drug Interactions (7.1 and 7.3) and Clinical Pharmacology (12.2) ].
After ella intake, menses sometimes occur earlier or later than expected by a few days. In clinical trials, cycle length was increased by a mean of 2.5 days but returned to normal in the subsequent cycle. Seven percent of subjects reported menses occurring more than 7 days earlier than expected, and 19% reported a delay of more than 7 days. If there is a delay in the onset of expected menses beyond 1 week, rule out pregnancy.
Nine percent of women studied reported intermenstrual bleeding after use of ella.
ella does not protect against HIV infection (AIDS) or other sexually transmitted infections (STIs).
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
ella was studied in an open-label multicenter trial (Open-Label Study) and in a comparative, randomized, single-blind, multicenter trial (Single-Blind Comparative Study). In these studies, a total of 2,637 (1,533 + 1,104) women in the 30 mg ulipristal acetate groups were included in the safety analysis. The mean age of women who received ulipristal acetate was 24.5 years and the mean body mass index (BMI) was 25.3. The racial demographics of those enrolled were 67% Caucasian, 20% Black or African American, 2% Asian, and 12% other.
The most common adverse reactions (≥ 10%) in the clinical trials for women receiving ella were headache (18% overall) and nausea (12% overall) and abdominal and upper abdominal pain (12% overall). Table 1 lists those adverse reactions that were reported in ≥ 5% of subjects in the clinical studies (14).

Adolescents: the safety profile observed in adolescents aged 17 and younger in studies and post-marketing is similar to the safety profile in adults [see Pediatric Use (8.4)].
The following adverse reactions have been identified during post-approval use of ella: Skin and Subcutaneous Tissue Disorders: AcneBecause these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
