Ampicillin (Generic) Capsules for Dogs, Cats, & Horses, 250 mg or 500 mg

Ampicillin Capsules are a foundational veterinary broad-spectrum penicillin antibiotic formulated for oral administration to treat susceptible bacterial infections across canine, feline, and equine patients. Containing the active aminopenicillin bactericidal compound, this professional-grade therapeutic preparation inhibits bacterial cell wall synthesis to combat a wide variety of respiratory, urinary, gastrointestinal, and soft tissue pathogens. Because effective antimicrobial therapy requires accurate diagnosis and proper dosing intervals, administration must be guided by veterinary clinical oversight.

What Are Ampicillin Capsules?

Ampicillin is a specialized veterinary beta-lactam antibiotic compound formulated for oral delivery under professional veterinary supervision.

Active Ingredients and Formulation

• Active Component: Ampicillin trihydrate or anhydrous ampicillin equivalent to 250 mg or 500 mg per capsule. It acts as a bactericidal antibiotic that penetrates bacterial cell walls and halts peptidoglycan synthesis in susceptible Gram-positive and select Gram-negative organisms.

• Vehicle and Presentation: Supplied as oral gelatin capsules packaged in containers of 100 or 250 counts designed for convenient dosing across small and large animal veterinary practices.

What Are They Used For?

Primary Veterinary Indications

• Respiratory Tract Infections: Routinely prescribed by veterinarians to treat bacterial pneumonia, bronchitis, and upper respiratory infections caused by susceptible streptococci or staphylococci.

• Genitourinary Tract Infections: Utilized to manage bacterial cystitis, urethritis, and secondary urinary tract infections in dogs and cats.

• Soft Tissue and Skin Infections: Indicated for wound infections, abscesses, and superficial pyoderma resulting from susceptible bacterial pathogens.

Administration and Dosage Considerations

Route and Dosing

• Route of Administration: Administered orally, typically given on an empty stomach (or with a minimal amount of food if gastrointestinal upset occurs) to optimize systemic absorption.

• Standard Dosage Reference:

  • Canine and Feline Oral Dosage: Typically administered at 10 mg to 20 mg per lb (22 mg to 44 mg per kg) of body weight administered every 8 to 12 hours, or as directed by your veterinarian.

  • Equine Oral Dosage: In foals or small equines, dosed strictly according to veterinary protocol (note: oral penicillins can disrupt normal hindgut microflora in adult horses and must be used with extreme caution).

• Veterinary Supervision: Treatment duration and precise dosing intervals must be determined exclusively by a licensed veterinarian based on culture and sensitivity testing where appropriate.

Important Safety Information

• Contraindications: Do not administer to animals with a known history of severe hypersensitivity or allergic reactions to penicillins or cephalosporins. Do not use orally in adult horses or rabbits due to the risk of severe, fatal antibiotic-induced colitis.

• Side Effects and Precautions: Generally well tolerated, but can occasionally cause mild gastrointestinal disturbances such as vomiting, diarrhea, or loss of appetite. Prolonged antimicrobial use can lead to secondary or superinfections with resistant organisms.

• Withdrawal Periods: Observe mandatory meat and milk withdrawal intervals established by regulatory authorities if treating food-producing livestock or equines intended for human consumption.

• Professional Guidance: Due to its systemic antimicrobial profile and the importance of responsible stewardship, use must be managed under direct veterinary clinical oversight.

Storage and Handling

• Store at controlled room temperature between 15°C and 30°C (59°F to 86°F), protected from moisture, excessive heat, and direct sunlight.

• Keep the container tightly sealed when not in use to protect the capsules from humidity.

• Keep securely out of reach of children, unauthorized individuals, and animals at all times.
