Composition and release form of the drug
The main active ingredients of the drug are synthetic hormones (analogues of the natural hormones estrogen and gestogen) ethinyl estradiol and acetobumedone. The latter has an effect on the pituitary gland, preventing the production of follicle-stimulating (FSH) and luteinizing hormones (LH). Ethinyl estradiol changes the internal structure of the uterus and the structure of the endometrium.
The drug Contrasex regulates sexual heat in cats.
Available in the form of a solution, packaged in special dropper bottles, 3 ml in volume, or in the form of tablets, 10 pieces in a blister. Both the bottle with the solution and the tablets are packaged in cardboard boxes with an instruction insert. Additional substances in the tablets are milk sugar, starch, calcium stearate and dye. Soybean oil, flavoring and coloring are added to the drops.
General description and properties
Acetobumedone interferes with the production of FSH and LH, hormones responsible for the formation of follicles in the ovaries and their subsequent ovulation. Ethinyl estradiol (artificial estrogen) is a female sex hormone that, in large quantities, can change the structure of the uterus and make vaginal mucus more viscous. And this, in turn, prevents sperm from penetrating into the uterine cavity, reduces their motility and prevents the fertilized egg from settling in the endometrial layer.
Both ethinyl estradiol and acetobumedone are quickly absorbed in the intestine, processed in the liver and completely excreted from the cat’s body in urine within two days.

Instructions for use and dosage for cats
The drug should be given only at the very beginning of the cat’s estrus or sexual activity in the cat. There is no point in using it later - it will not help. The dosage depends on the weight, age and gender of the animal. For cats weighing up to 5 kg, 4 drops of Contrasex once a day, an hour before meals, is enough. If we are talking about the tablet form, then give one tablet once a day.
It is recommended to give cats weighing from 5 to 10 kg 6-8 drops or 2 tablets, with the same interval. For cats whose weight does not reach 5 kg, the dosage will be 8-10 drops per dose or 2 tablets, and for cats weighing up to 15 kg - 12-15 drops or 3 tablets. The course of treatment for cats will be 3-4 days, and for cats – 4-5 days.
To consolidate the effect, the instructions for use recommend extending the use of the drug for another day. If more than 2 days have passed since the start of estrus, then Contrasex cannot be used. It is also not worth using it more than 2 times a year, as this can lead to dire consequences. As a preventive measure, you can give the medicine once every 2 weeks, 4 drops per dose.
General information
The result is complete suppression of arousal and the impossibility of pregnancy. The drug is excreted from the liver in a few days along with urine, the general condition improves, and the symptoms of aggression and anxiety decrease. If the drug is discontinued, reproductive function is restored within 3-4 months. Contrasex is suitable for cats, male cats, and female dogs.
The drug is produced in 2 forms: drops (3 ml bottle), and tablets (10 pieces). Acetobumedone prevents the production of hormones responsible for the formation of follicles and subsequent ovulation. Ethinyl estradiol is a hormone, a large amount of which changes the uterine structure and prevents the penetration of sperm into the uterine cavity.
The hormonal drug “Contrasex” in both forms is sold in cardboard packaging, each with instructions. It states that it makes sense to give the drug at the very beginning of a cat’s sexual activity or the cat’s estrus. Using it later won't do anything. The dosage indicates that it depends on weight, age and gender.
For a five-kilogram cat, 4 drops per day once before meals (an hour and a half before it) will be enough. Or one tablet according to a scheme similar to drops. If the cat's weight is between 6-10 kg, double the dose. In this case, the reception also remains one-time. The course of using “Contrasex” is up to days. Cats require more drops and tablets, with a weight within 5 kg - drop 8-10 drops or 2 tablets, over 6, but less than 15 kg - 3 tablets or 12-15 drops.
Give the drug for up to 5 days. To consolidate the effect of the drug, you can give it one more day; it is not recommended to use contrasex more than 2 times a year. Prevention can be carried out according to the scheme of 4 drops every two weeks. You cannot give a cat “contrasex” for more than one and a half years. No drug overdoses have been identified.
Contraindications in the instructions include cats that are nursing, pregnant, with pathologies of the uterus, mammary glands, acute and chronic diseases. With prolonged use of Contrasex, there is a risk of endometritis, pyometra, formations, both benign and malignant, in the mammary glands and uterus.

Reviews about the drug
Inna. I gave my cat Contrasex drops for a year. The cat became calm, I did not observe any side effects. I have heard many different opinions about hormonal contraceptives. But I believe that if you strictly follow the instructions, then everything will be fine. I have no complaints about the drug.
Cat owners believe that using Contrasex according to the instructions will not harm the animal.
Elena. When my cat first started screaming at night and marking his territory, I turned to my veterinarian for advice. He recommended using Contrasex tablets. I gave my cat 2 tablets a day at one time, before feeding. The cat became absolutely calm and stopped marking furniture and walls. True, I began to eat more, but within normal limits. In my opinion, it is an excellent drug with no side effects.
Contraceptives CounterSex drops for cats and bitches
It all started at the very end of the 90s of the last century. In terms of veterinary medicine, these are wild times in our province—one might say the real Middle Ages. There are no traces of normal veterinary clinics; various kinds of drugs for four-legged animals have just begun to appear on the market.
And then my then very young cat begins her “concerts”, demanding a friend for body and soul, so to speak. An animal that is already emotional, my cat simply turned into some kind of fury, screaming as if driven day and night, giving none of the household members any peace or sleep. Now this problem is solved by sterilization - in a civilized manner and forever. At that time this concept existed somewhere among legends, in the field of fantasy.
But it was already quite possible to purchase hormonal drugs for animals. This is what I did on the advice of a friend who had been “calming” her cat in this way for more than one year (!)
At first everything went fine. The first heats were stopped, the subsequent ones became easier and easier. In total, I didn’t use “Countersex” in relation to my animal for too long - about a year (all according to the instructions!). When, a few years later, the kitty took up her old routine with the same enthusiasm, I already knew about the existence of a much more gentle drug “Cat Bayun” and gave my cat only it.
As time went. I knew that taking hormones, even if not very long-term, would not turn out to be anything good for my cat, but I hoped for the best. However, in the 10th year of the cat’s life, we were faced with consequences - it turned out that my beauty had oncology.
By that time, the city already had good veterinary clinics with decent specialists, so we fought the disease for 5 years, persistently and desperately. Four operations, supportive therapy, a lot of nerves and money spent on treatment... And, alas, the natural ending.
I hate to think about it, but I myself became an indirect cause of my cat’s death. The cat was of “noble” origin, with good heredity and no congenital health problems. If there were no hormonal drugs in her life, with a high degree of probability she would have lived several more years beyond her 14th birthday. Forgive me, my dear, if you can...
I want to appeal to all animal owners. Please be humane - do not feed your pets “Countersex” and other poisons! The effectiveness and safety of such drugs is just an appearance! Sooner or later you will have to pay for everything!
How can I recommend this?!!!
