Clamoxyl Ready-to-Use 150 mg/ml suspension for injection.


Clamoxyl Ready-To-Use 150 mg/ml suspension for injection is a sterile off-white suspension containing 150 mg/ml amoxicillin as Amoxicillin trihydrate.


Amoxicillin is a broad spectrum semi-synthetic penicillin which is bactericidal in vitro against a wide range of Gram-positive and Gram-negative bacteria including the following: Actinomyces spp; Bacillus spp; Bordetella bronchiseptica; Clostridium spp; Corynebacterium spp; Escherichia coli; Fusobacterium spp; Haemophilus spp; Leptospira spp; Moraxella spp; Pasteurella spp; Proteus spp; Salmonella spp; streptococci; staphylococci (penicillin-sensitive strains).

Clamoxyl RTU is indicated for the treatment of infections in dogs, cats, sheep, pigs and cattle, caused by amoxicillin sensitive organisms.

Dosage and administration

The recommended dosage rate is 7 mg/kg bodyweight once daily for up to 5 days by subcutaneous (dogs, cats), or intramuscular (dogs, cats, sheep, pigs, cattle) injection.

If the volume to be given is greater than 15 ml (cattle) and 5 ml (sheep and pigs), the dose should be divided and the remaining should be injected in another site.

The following is intended as a guide



weight (kg)

Dose (volume)




Store Cattle





















Dog  – large



– medium



– small








As a guide this is equivalent to 0.25 ml per 5 kg daily.

Shake the vial well to suspend the active ingredient before use. Swab the rubber septum and remove the required volume aseptically.

Massage the injection site after administration. Use a new anatomical site for repeated injections. To ensure the correct dosage, bodyweight should be determined as accurately as possible to avoid overdosing.

In common with other penicillin preparations hydrolysis takes place rapidly in the presence of water. It is important, therefore, that a dry syringe is used when extracting suspension for injection to avoid contaminating the remaining contents of the vial with drops of water.

Contra-indications, warnings, etc

Not to be used in rabbits, guinea pigs, hamsters or gerbils.

The suspension is not suitable for intravenous or intrathecal administration.

Do not use in animals with known sensitivity to the active substance.

Use of the product may result in local tissue reaction.

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 epidemiological information.

Clamoxyl RTU is not effective against beta-lactamase producing organisms.

Withdrawal periods

Meat: Cattle: 54 days.

Sheep: 47 days.

Pigs: 47 days.

Milk: Cattle: 60 hours from the last treatment.

Not to be used in sheep producing milk for human consumption.

Operator warnings

Care should be taken to avoid accidental self-injection.

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 reaction to these substances may occasionally be serious.

Do not handle this product if you know you are sensitised, or if you have been advised not to work with such preparations.

Handle this product with great care to avoid exposure, taking all recommended precautions.

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.

Wash hands after use.

Pharmaceutical precautions
