Ulipristal Acetate is contraindicated in case of hypersensitivity to active substances and in pregnancy.

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.

Ulipristal Acetate interacts with the following drugs: Barbiturates, Carbamazepine, Phenobarbital, Rifampicin, Itraconazole, Ketoconazole etc.

Most common side-effects are headache, nausea, abdominal pain, dysmenorrhea, fatigue, dizziness, breast tenderness etc.

Experience with Ulipristal Acetate overdose is limited, in a clinical study, a single dose equivalent to four times Ulipristal Acetate was administered to a limited number of subjects without any adverse reactions.

Contraindicated in suspected or existing pregnancy. Ulipristal Acetate excretes in breast milk. So breastfeeding is not recommended for one week after intake. Extremely limited data are available on the health of the fetus/newborn exposed to Ulipristal acetate.

Existing Pregnancy: Ulipristal Acetate 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: Ulipristal Acetate is for occasional use as an emergency contraceptive. It should not replace a regular method of contraception. Repeated use of Ulipristal Acetate 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 Ulipristal Acetate 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 Ulipristal Acetate 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 Ulipristal Acetate.

Hepatic Impairment: No studies have been conducted to evaluate the effect of hepatic disease on the disposition of Ulipristal Acetate.Renal Impairment: No studies have been conducted to evaluate the effect of renal disease on the disposition of Ulipristal Acetate.
