(amoxicillin tablets)

For use in DOGS only.

Approved by FDA under NADA # 065-492


BIOMOX® (amoxicillin tablets) are a broad-spectrum, semisynthetic antibiotic which provides bactericidal activity against a wide range of common gram-positive and gram-negative pathogens. Amoxicillin chemically is D-(-)α-amino-p-hydroxybenzyl penicillin trihydrate.

Inactive Ingredients

Dibasic Calcium Phosphate Dihydrate, Magnesium Stearate, Microcrystalline Cellulose and Sodium Starch Glycolate.


Amoxicillin has bactericidal activity against susceptible organisms similar to that of ampicillin. It acts by inhibiting the biosynthesis of bacterial cell wall mucopeptides. Most strains of the following gram-positive and gram-negative bacteria have demonstrated susceptibility to amoxicillin, both in vitro and in vivo: nonpenicillinase-producing staphylococci, alpha- and beta-hemolytic streptococci, Enterococcus faecalis, Escherichia coli and Proteus mirabilis. Amoxicillin does not resist destruction by penicillinase; therefore, it is not effective against penicillinase-producing bacteria, particularly resistant staphylococci. Most strains of Enterobacter and Klebsiella and all strains of Pseudomonas are resistant.

Amoxicillin may be given without regard to meals because it is stable in gastric acid. It is rapidly absorbed following oral administration and diffuses readily into most body fluids and tissues. It diffuses poorly into the brain and spinal fluid except when the meninges are inflamed. Most of amoxicillin is excreted in the urine unchanged.

Biomox Tablets Indications

BIOMOX® (amoxicillin tablets) are indicated in the treatment of the following infections in dogs when caused by susceptible strains of organisms:

BACTERIAL DERMATITIS due to Staphylococcus aureus, Streptococcus spp., Staphylococcus spp., and Escherichia coli.

SOFT TISSUE INFECTIONS (abscesses, wounds, lacerations) due to Staphylococcus aureus, Streptococcus spp., Escherichia coli, Proteus mirabilis, and Staphylococcus spp.

With all antibiotic therapy, appropriate in vitro cultures and sensitivities should be conducted prior to treatment.


The use of amoxicillin is contraindicated in animals with a history of an allergic reaction to penicillin.

Adverse Reactions

Amoxicillin is a semisynthetic penicillin and, therefore, has the potential for producing allergic reactions. Epinephrine and/or steroids should be administered if an allergic reaction occurs.


For use in dogs only.


Until adequate reproductive studies are accomplished, BIOMOX® (amoxicillin tablets) should not be used in pregnant or breeding animals.

Biomox Tablets Caution

Federal law restricts this drug to use by or on the order of a licensed veterinarian.

Dosage and Administration

The recommended dosage is 5 mg per pound of body weight administered twice daily for 5 to 7 days or 48 hours after all symptoms have subsided. If no improvement is noted in 5 days, the diagnosis should be reconsidered and therapy changed.
