Clinical information

Huvamox 800 mg/g Powder for Use in Drinking Water for Chickens, Turkeys, Ducks and Pigs — SPC Details

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

In chickens, turkeys and ducks: Treatment of infections caused by bacteria
susceptible to amoxicillin.
In pigs: For the treatment of pasteurellosis caused by Pasteurella multocida
susceptible to amoxicillin.
Do not use in horses, rabbits, guinea pigs, hamsters, gerbils or any other small
herbivore given that amoxicillin, as for all aminopenicillins, has a deleterious effect on
caecal bacteria.
Do not use in ruminants.

Revised: May 2024
AN: 03034/2022Page 2 of 8
Do not use in animals with hypersensitivity to penicillins or other ß-lactam antibiotics
or to any of the excipients.
Do not administer to animals with renal disease including anuria or oliguria.
Do not use in the presence of ß-lactamase-producing bacteria.
Chickens, ducks, turkeys and pigs:
Undetermined frequency
(cannot be estimated from the
available data)
Hypersensitivity reaction (varying from allergic
skin reaction to anaphylactic shock) Digestive
tract disorders (vomiting, diarrhoea)
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system.
The veterinary medicinal product is not effective against beta-lactamase producing
organisms.
Cross-resistance has been shown between amoxicillin and other penicillins, in
particular amino-penicillins in bacteria susceptible to amoxicillin. Use of the veterinary
medicinal product/amoxicillin should be carefully considered when susceptibility
testing has shown resistance to penicillins because its effectiveness may be reduced.
The uptake of medication by animals can be altered as a consequence of illness. In
case of insufficient water uptake, animals should be treated parenterally instead
using a suitable injectable veterinary medicinal product prescribed by the
veterinarian.

Special precautions for use in animals
Use of the veterinary medicinal product should be based on susceptibility
testing of the target pathogen(s). If this is not possible, therapy should be based
on epidemiological information and knowledge of susceptibility of the target
pathogens at farm level or at local/regional level. Use of the veterinary
medicinal product should be in accordance with official, national and regional
antimicrobial policies. Use of the veterinary medicinal product deviating from the
instructions given in the SPC may increase the prevalence of bacteria resistant
to amoxicillin and may decrease its effectiveness and the effectiveness of
treatment with other penicillins, due to the potential for cross-resistance.
Narrow spectrum antibiotic therapy with a lower risk of antimicrobial resistance
selection should be used for first line treatment where susceptibility testing
suggests the likely efficacy of this approach.
The antimicrobial should not be used as part of heard health programmes.
Not for use for prophylaxis.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
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.
People with known hypersensitivity to beta-lactam antibiotics should avoid
handling the veterinary medicinal product.
Handle this veterinary medicinal product with great care to avoid exposure,
taking all recommended precautions.
Avoid inhalation of dust. Wear either a disposable half-mask respirator
conforming to European Standard EN149 or a non-disposable respirator to
European Standard EN140 with a filter to EN143.

Wear gloves during preparation and administration of medicated water or liquid
feed.
Wash hands after use. Wash any exposed skin after handling the veterinary
medicinal product or medicated water or feed.
In the event of eye or skin contact, rinse the affected area with large amounts of
clean water.
Do not smoke, eat or drink while handling the veterinary medicinal product. In
case of accidental ingestion, immediately rinse the mouth with water and seek
medical advice.
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.
Special precautions for the protection of the environment
Not appliable
Other precautions
Not applicable
The veterinary medicinal product should not be administered with antibiotics that
have a bacteriostatic mode of action, such as tetracyclines, macrolides,
sulphonamides as they can antagonise the bactericidal effect of penicillins.
Do not use simultaneously with neomycin since it blocks the absorption of oral
penicillins.
