Special precautions to be taken by the person administering the veterinary medicinal product to animals

Care should be taken to avoid contact with the skin. Wash hands after use.

Sulphonamides may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to sulphonamides may lead to cross reaction with other antibiotics. Allergic reaction to these substances may occasionally be serious.

1. Do not handle this product if you know you are sensitive to sulphonamides.

2. If you develop symptoms following exposure such as a skin rash, you should seek medical advice and show the doctor this warning.

4.6 Adverse reactions (frequency and seriousness)

Chronic usage of oral neomycin may result in bacterial or fungal superinfections.

4.7 Use during pregnancy, lactation or lay

The product is intended for use in calves only.

Do not use in lactating cows.

4.8 Interaction with other medicinal products and other forms of interaction

There is interaction and antagonism between sulphonamides and the Vitamin B Complex. Do not use local anaesthetics of the procaine group during treatment, as they are antagonistic to the sulphonamide component.

4.9 Amounts to be administered and administration route

Shake the bottle well before use.

Administration is by oral drench.

4 ml per 10 kg bodyweight twice daily for a maximum period of 5 days. This equates to 60 mg/kg Sulfadiazine and 10 mg/kg Neomycin twice daily. To ensure correct dosage, body weight should be determined as accurately as possible to avoid underdosing.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Antidiarrheals, intestinal anti-inflammatory/antiinfective agents, intestinal antiinfectives, antibiotics

ATCvet code: QA07AA51

5.1 Pharmacodynamic properties

Sulphadiazine is a broad spectrum antimicrobial agent. It acts by interfering with the biosynthesis of folic acid in bacterial cells, competitively preventing para-aminobenzoic acid (PABA) from incorporation into folic acid molecule.

Neomycin is the isomeric mixture of Neomycin Band C. It has a rapid dose related bactericidal action on susceptible microorganisms. The antibacterial action is directed primarily against aerobic gram negative bacteria.

5.2 Pharmacokinetic particulars

Sulfadiazine is rapidly absorbed from the gastrointestinal tract and widely distributed to all tissues and body fluids. The sulphonamides are eliminated by a combination of renal excretion and biotransformation.

Neomycin is poorly absorbed from the gastrointestinal tract, has a short half-life and is nearly all excreted unchanged from the gastrointestinal tract.
