Clinical information

Vetrimoxin 50 mg/g Premix for Medicated Feeding Stuff for Pigs — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

In weaned piglets: in herds where infection has been confirmed; treatment of infections
caused by susceptible to amoxicillin.

For oral administration only after incorporation in feed.In-feed use at the final dose 15 mg
amoxicillin/ kg b.w./ day, during 14 consecutive days.
In the case of an altered feed intake (clinical status, weight class, age, environment),
adjust the incorporation rate in order to guarantee an intake of 15 mg amoxicillin/kg
b.w./day.
According to the recommended dose, the number and animals weight to be treated, the
exact dose of medicinal product to be incorporated in the feed should be calculated using
the following formula:
0.3 g of medicinal product X Average bodyweight of treated animals (kg) / day
=
kg Vetrimoxin/ton of feed Daily feed intake (kg)
During the granulation, mixture should not reach a temperature above 60ºC.
Body weight should be evaluated accurately to avoid underdosing.
Feed intake depends on the clinical condition of the animal, thus the concentration in the
feed should be adjusted to assure the correct dosage. Mix well to ensure homogeneous
distribution.
The medicated feed should be the only source of feed during the 14 days of treatment,
which represents the maximum period of treatment with the product.
A manufacturer who is approved to incorporate directly at any concentration, veterinary
medicinal products or premixtures containing such products must be responsible for
mixing when incorporation is less than 2 kg per tonne for final feed.

Do not use in cases of hypersensitivity to penicillins, to other β-lactams or to the excipient.
Do not use orally to rabbits, guinea pigs, hamsters and horses since the amoxicillin, like all
the aminopenicillins, has adverse impact on caecal microflora population.Do not use in the
presence of ß-lactamase-producing bacteria.

In very rare cases, the following adverse reactions may occur:
- Hypersensitivity reactions, the severity varying from skin rash to anaphylactic shock.
- Gastrointestinal symptoms (vomiting, diarrhoea).
- Haematology disturbances and colitis.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated reports)

Sick animals may have reduced feed intake and consequently, may require parenterally
administered medication instead.
The intake of medicated feed depends on the clinical condition of the animals. In order to
obtain the correct dosage the concentration of amoxicillin has to be adjusted accordingly.

Special precautions for use in animals
Official, national and regional antimicrobial policies should be taken into account when the
product is used.
Use of the product should be based on susceptibility testing of the bacteria isolated from
the animal. If this is not possible, therapy should be based on local (regional, farm level)
epidemiological information about susceptibility of the target bacteria.
Use of the product deviating from the instructions given in the SPC may increase the
prevalence of bacteria resistant to the amoxicillin and may decrease the effectiveness of
the treatment.
The prolonged or repeated use should be avoided by e.g. improving management
practices, proper cleaning and disinfection. Particular attention should be paid to
improvement of farming practices to avoid any stress condition.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Persons handling this product should avoid inhalation of any dust and contact with skin.

a non-disposable respirator to European Standard to EN140 with filter EN143 when mixing
or handling this product.
Rubber gloves should be worn when mixing or handling this product. Hands and exposed
skin should be washed thoroughly after use.
Do not smoke, eat or drink while handling the product.
Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection,
inhalation, ingestion or skin contact. Hypersensitivity to penicillins may lead to cross
reactions to cephalosporins and vice versa. Allergic reactions to these substances may
occasionally be serious.
1. Do not handle this product if you know you are sensitised, or if you have
been advised not to work with such preparations.
2. Handle this product with great care to avoid exposure, taking all
recommended precautions.
3. If you develop symptoms following exposure such as a skin rash, you should
seek medical advice and show the doctor this warning. Swelling of the face,
lips or eyes or difficulty with breathing, are more serious symptoms and
require urgent medical attention.

Do not use simultaneously with neomycin since it blocks the absorption of oral penicillins.
Do not use jointly with antibiotics that inhibit the bacterial protein synthesis since they can
antagonise the bactericidal action of penicillins.

This veterinary medicinal product does not require any special storage conditions.
