Warnings & Precautions
Existing Pregnancy
: 5X is not indicated for termination of an existing pregnancy.
Ectopic Pregnancy
: A history of ectopic pregnancy is not a contraindication to the use of this emergency contraceptive method.
Repeated Use
: 5X is for occasional use as an emergency contraceptive. It should not replace a regular method of contraception. Repeated use of 5X within the same menstrual cycle is not recommended, as safety and efficacy of repeat use within the same cycle has not been evaluated.
Fertility Following Use
: A rapid return of fertility is likely following treatment with 5X for emergency contraception. So, to prevent pregnancy on a later episode of sexual intercourse one should use the barrier method (ex. Condom).
Effect on Menstrual Cycle
: After 5X 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. 7% 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, a pregnancy test should be performed. 9% of women studied reported intermenstrual bleeding after the use of 5X.
Pharmacology & Mechanism of Action
Ulipristal Acetate is an orally-active synthetic SPRM that acts via high-affinity binding to the human progesterone receptor. The primary mechanism of action is inhibition or delay of ovulation. Data shows that even when taken immediately before ovulation is scheduled to occur, Ulipristal Acetate is able to postpone follicular rupture in some women.
