Sex Barrier for Cats

Sex Barrier is a hormonal contraceptive used to stop or prevent sexual activity in cats. Astrapharm developed a separate formula for females and males. Compared to similar hormonal medications, Sex Barrier is considered safe. When used correctly, any potential negative effects on the animal are minimized.

General description

The hormonal medication is available in both drops and tablet form, allowing owners to choose the most convenient option based on their pet's personality. The active ingredients in both are similar, meaning their effects and properties are identical.

Please note! Sex Barrier is available in two versions – for male and female cats. The only difference is the concentration of active ingredients. Please be careful when purchasing this medication. Do not use the product intended for males on female cats, as it can cause an overdose.

The drops are produced as a clear, light-yellow solution. They are typically packaged in polymer bottles with dropper tips. These droppers make it easy to measure the required amount of medication. They contain not only hormonal components but also olive oil, which contains vitamins F, A, and E. Olive oil promotes better absorption of the active ingredients, and the vitamins have an antioxidant effect, helping to detoxify the body.

The oval-shaped tablets are pink on one side and white on the other. They are packaged in blisters, each containing 10 tablets. They contain potato starch, lactose, and other excipients.

Regardless of dosage form, the medication should be stored at a temperature above freezing, but no higher than 25˚C. The solution may be frozen briefly during transportation. After thawing, it retains its pharmacological properties.

Action and properties

Sex Barrier has a pronounced contraceptive effect due to the combination of two components: water-soluble mepregenol acetate and ethinyl estradiol. These synthetic hormones complement each other, providing a comprehensive effect on the body.

The medication's contraceptive effect is achieved by its active ingredients influencing the production of hormones responsible for follicle maturation. This results in ovulation being stopped. Furthermore, the viscosity of cervical mucus increases, leading to changes in the endometrium. Due to its thickening, the fertilized egg cannot implant.

The drug is also capable of correcting behavior, as it has the following effects:

• has a calming effect on the nervous system;
• eliminates excessive aggressiveness;
• stops the animal's desire to mark its territory;
• allows you to get rid of other unpleasant symptoms of sexual desire.

By the second or third day of treatment, the animal stops screaming, marking its territory, and otherwise expressing its desire to mate with a male of the opposite sex. The pet's behavior quickly returns to normal.

When to apply

According to the instructions, Sex Barrier for cats is used for the following purposes:

• delay of estrus, regulation of the sexual cycle;
• cessation of estrus;
• correction of behavior during sexual hunting;
• pregnancy prevention.

Using the drug for cats allows you to suppress their sexual activity and get rid of unpleasant symptoms:

• marking territory;
• loud meowing;
• vagrancy;
• other violations of habitual behavior.

Sometimes the Sex Barrier is used as a sedative during transport or when visiting a place with many other animals (for example, when participating in shows and competitions, visiting a pet hotel, or visiting a veterinary clinic). Contact with other pets can cause excessive agitation, aggression, and other problems, and the Sex Barrier helps prevent these.

How to apply

The use of the drug depends on several factors:

• goals (behavior correction, delay or termination of estrus);
• dosage form (drops or tablets);
• weight of the animal.

Before starting the course, consult your veterinarian. They will correctly calculate the dosage based on your pet's specific needs.

Many cat owners prefer Sex Barrier drops for their ease of use. The solution can be placed in the mouth or nose (the animal will lick it off). For more assertive cats, the medication can be placed on a piece of meat, a small piece of dry food, or another treat. Typically, administration is straightforward. The tablets should be placed on the tongue or crushed into a powder and mixed with a small amount of food.

Doses and regimens may be as follows:

1. To maintain calm and prevent the onset of estrus, a hormonal medication is administered during the female's resting period. The treatment course lasts 3 days and should be repeated once a month. The daily dosage is independent of weight. Four drops or one tablet should be given daily.
2. If a female cat experiences unwanted heat, administer the medication daily to stop it in the following doses: 4 drops or 1 tablet for cats up to 5 kg; 5-7 drops or 1-2 tablets for females over 5 kg. The medication should be administered for 3-5 days until the heat symptoms completely disappear. It is important to begin administering the hormonal medication within the first 2 days of the onset of heat symptoms. Failure to begin administration promptly may result in its ineffectiveness.
3. If pregnancy needs to be prevented, the cat is given 8 drops or 2 tablets of Sex Barrier within 24 hours of mating. In this case, the medication is taken once and does not require re-application.

To stop sexual activity in male cats, the medication is administered once daily for 4-6 days. The dosage is calculated based on weight:

• for pets weighing less than 5 kg – 4 drops or 1 tablet;
• for animals weighing more than 5 kg – 5-7 drops or 1-2 tablets.

To control a cat's behavior during sexual arousal, a course of treatment should be started at the first sign of arousal. To prevent males from going into heat, the hormonal medication is administered in three-day courses every month. The daily dose is 4 drops or 1 tablet, regardless of the animal's weight or age. Courses should be administered during periods of sexual inactivity.

If the medication is planned for use as a sedative, it is preferable to use a solution. The medication is administered 24 hours before the expected stressful event in the following doses:

• if weight is less than 5 kg - 4 drops;
• if more than 5 kg – 5-7 drops.

When banned

According to the instructions for use, Sex Barrier for cats should not be used in the following cases:

• for urolithiasis;
• in pathologies of the reproductive system;
• in diabetes mellitus;
• in case of an allergic reaction to the components.

Please note: Use this medication with caution in young animals, as it is contraindicated for pets that have not yet reached sexual maturity.

Because the drug affects the hormonal system, it should not be used during pregnancy or lactation. Contraceptive use should also be discontinued if you have breast tumors, as they may accelerate their growth.

If the manufacturer's recommended dosages are followed, the risk of side effects is virtually zero. If an allergic reaction occurs due to intolerance to the components, further use of the hormonal medication is discontinued, the animal is given antiallergic medications, and symptomatic therapy is administered if necessary. If the dosage is exceeded or the medication is used for a longer period (more than 18 months without interruption), the hormonal medication may provoke the development of reproductive system pathologies or cause serious behavioral problems.

What is the price

The price of Sex Barrier for cats depends on the release form:

• drops, 2 ml – about 330 rubles;
• tablets, 10 pcs. – about 240 rubles.

When purchasing, pay attention to whether the medication is intended for females or males. In addition to this information being provided on the packaging, you can also distinguish the medications by their color. The box containing the medication for female cats is red, while the box containing the medication for male cats is blue.

Owner reviews

Elena, owner of a 6-year-old cat:

"We've been using Sex Barrier tablets for our cat for several years now. After 2-3 doses, she becomes calm, stops running outside, and stops doing her business in inappropriate places. There are no side effects. It's a great option for owners who are hesitant about surgery."

Marina, owner of a British cat:

"Sex Barrier was a real lifesaver for us during our Margo's last heat. She became so aggressive that I began to fear for my children. Before, she'd just purr constantly. We used to put drops on her nose, and she'd lick them off easily. The medication was effective, but after what we went through, we decided to spay her."

Veterinarian Reviews

Olga, a veterinarian with 12 years of experience:

"The manufacturer claims Sex Barrier is safe. However, I want to warn pet owners that there are no safe hormonal medications. Try to avoid using this medication if your pet's health is important to you."

Vladimir, a veterinarian with 7 years of experience:

"An effective contraceptive. Unlike herbal remedies, it always helps stop a dog's heat cycle and calms the animal, but it shouldn't be overused, as it contains hormones. It should only be used in emergency situations. For those who don't want kittens, I recommend surgery to avoid subjecting your pet to chemicals for the rest of its life."
