Pharmacological properties

The active components of the drug – mepregenol acetate and ethinylestradiol, by interacting with the hypothalamic-pituitary system of the animal's body, prevent the maturation of ovarian follicles and terminate the estrus. In case of unwanted mating, the components of the drug actively prevent fertilization of the egg, thereby preventing an accidental pregnancy.

Mepregenol acetate is a synthetic analogue of the natural hormone progesterone. Ethinylestradiol is an analog of the natural hormone estradiol.

Sex BARRIER drops gently and reversibly affect the hormonal system of the male cats: in 2-3 months after the drug termination, the reproductive function of the animal's body is fully restored. According to the degree of influence on the animal's body, the drug is classified as a low-risk (harmless) substance.

Usage and dosage

In order to reduce sexual activity and to eliminate aggressive behavior in female cats, it is recommended to administer the drug daily for 3-5 days during the first signs of estrus. Depending on the animal’s body weight the daily dose of the drug is as follows:

  • Up to 5 kg – 4 drops;
  • Over 5 kg – 5-7 drops.

SEX BARRIER is recommended for maintaining a calming effect in female cats. In order to ensure a low level of sexual activity of the animal, the drug is given to the female cat during sexual rest (anestrus) at a dose of 4 drops once a day, regularly every 2 weeks.

In case of accidental mating, to prevent the unwanted pregnancy, the contraceptive is given once in the amount of 8 drops within a day after accidental mating.

High quality and safety

The medicinal drug was developed and patented by LLC Research and Production Company SKiFF in 1999 under the supervision of leading experts of the Russian Academy of Sciences in Moscow. The SEX BARRIER trademark has been awarded Platinum and Gold Quality Marks of the State Standard of the Russian Federation.
