Ceftriaxone is an effective and powerful antibiotic that is used not only for cats, but also for humans. The main feature is the widest spectrum of action, but if improperly dosed or used, it can cause serious adverse reactions, even death, therefore it is strictly forbidden to use it without a doctor’s prescription.
Ceftriaxone is available as a white or yellowish powder. For its packaging, glass bottles are used, which are sealed with rubber stoppers and closed with aluminum caps. They allow you to maintain the tightness of the drug. Since the drug is used in the form of injections, the powder is diluted with water for injection or novocaine before use. 0.25, 0.5, 1 or 2 g of ceftriaxone sodium salt are placed in vials.
Powder containers are packed in cardboard boxes of 10 pieces, but in many pharmacies they are sold individually. The shelf life of closed vials is 3 years from the date of production, provided that they are stored away from sunlight at a temperature of 15 to 25 degrees Celsius. The prepared solution cannot be stored.
Important! The antibiotic cannot be used after the expiration date, therefore always pay attention to the date on the package.
How it works and when applied
Ceftriaxone is a third-generation antibiotic from a number of cephalosporins. The principle of its action is that it interferes with the synthesis of cell membranes in pathogenic microorganisms. As a result of this action, microbes die. The antibiotic begins to act 2-3 hours after administration to the body. Together with the bloodstream it spreads throughout the body, and is excreted in most of the kidneys.
The drug is effective against various bacterial infections:
- E. coli;
- Salmonella et al.
Ceftriaxone treatment for cats is recommended in the following cases:
- with otitis media;
- with sepsis;
- with bronchitis, pneumonia and other infectious diseases of the respiratory tract;
- with cystitis and other bacterial inflammation of the genitourinary system;
- with infections of the liver and biliary tract;
- with chladimiosis;
- with meningitis;
- with osteomyelitis and other pathologies of bones of bacterial origin;
- with infectious inflammation of the soft tissues;
- with gastrointestinal infections;
- with other pathologies caused by antibiotic-sensitive microorganisms.
Also, the medicine is prescribed in the postoperative period to prevent complications in the form of bacterial infections.
Dosage and administration
Medicinal powder is used to prepare the solution. It is usually administered intramuscularly. Usually injections are made in the back thigh, where a large number of muscles are located. It is allowed to administer the medicine to animals and intravenously, but at home it is difficult to do. The procedure can only be performed by a qualified doctor.
Note! It is strictly forbidden for cats to inject Ceftriaxone subcutaneously.
The powder can be diluted with water for injection or 1% novocaine. The second option is more preferable if the animal is not allergic to anesthetic, since antibiotic injections are very painful. But lidocaine for breeding an antibacterial powder should not be used, because in cats it often causes serious allergic reactions, including anaphylactic shock. In addition, lidocaine is able to greatly reduce blood pressure, which is why it is deadly for animals with cardiovascular diseases.
The dosage of the antibiotic is calculated taking into account the weight of the pet. According to the instructions for use, the dose of Ceftriaxone for cats is 20-40 mg per 1 kg of weight. To calculate how much solution is needed, you need to take into account the content of the antibacterial substance in the bottle. For cats, it is advisable to buy 0.25 g vials. If you add 3.5 ml of novocaine or water for injection in such a bottle, then for animals up to 2 kg 0.5 ml will be needed, and for larger pets - 1 ml. If 3.5 ml of dilution liquid is added to the vial with 0.5 g of medicinal powder, then 0.14-0.16 ml of solution is needed per 1 kg of weight.
Important! The ratio of the dilution liquid and the powder, as well as the dose of the prepared solution, should be calculated by the doctor. Do not self-medicate, as this can be fatal to the animal.
Injections are done once a day. At the first application, it is important to monitor the condition of the animal or to begin an allergy test before starting treatment. The course usually lasts 5-10 days, but is determined solely by the veterinarian, depending on the condition of the animal and the symptoms. If the condition of the pet does not improve in 2-3 days, you should choose another antibiotic.
How to give injections?
To prepare the solution, you must perform the following steps:

- Quickly insert the needle at an angle of 45 ° somewhere 1 cm into muscle tissue.

Maria, mistress of a purebred cat:
"Our beauty I picked up on the street. My health left much to be desired. The examination revealed sinusitis (mucus flowed from the nose with pus and blood). The doctor prescribed Ceftriaxone. The injections are very painful, but after the second injection the cat became much better, and after 7 -day course and completely recovered. "
Julia, mistress of a 7-year-old cat:
"This antibiotic nearly killed my cat. Now there are serious kidney problems and it is not known whether we can get out. We were prescribed Ceftriaxone to treat pancreatitis. Later we found out that the dose was almost doubled (we did everything according to the doctor’s recommendations). I think that it’s better to choose a safer drug, even if the treatment will be longer. "
Marina, a veterinarian with 12 years of experience:
"Ceftriaxone is a good antibiotic. In many cases, the hope is for a full recovery, but it should be used carefully. Only the doctor should calculate the dose. In my practice, there was a case when we tried to save the cat from an overdose, but, alas, our efforts were in vain. This drug definitely not suitable for self-medication. "
Michael, a veterinarian with 8 years of experience:
"Ceftriaxone is an inexpensive but effective antibacterial agent. Quite often, it is prescribed to both cats and dogs. Owners are advised to breed the powder with novocaine. Like most antibiotics, it can cause side effects (there have even been cases of pet death), but I think that the drug has advantages still more. "
