About & Sources
Baytara is a veterinary drug database that brings together active ingredients, animal species, withdrawal periods, and adverse effects in a single, easy-to-browse reference.
Our vision
We believe reliable veterinary drug information should be available in clear language and with verifiable sources. Many good veterinary references are scattered across government databases and product leaflets, making them hard for the busy vet, student, or breeder to reach quickly. Baytara brings this information together in one organized place without compromising its scientific accuracy or hiding its source.
Who is this site for?
For veterinarians
A quick reference for active ingredients, their drug classes, withdrawal periods, and known class-level interactions — to support clinical decisions, not replace them.
For students
Simplified articles and reviews explaining mechanisms of action and drug classes in clear language, with terms linked back to their original sources.
For breeders and animal owners
Practical calculators in one place: a dose calculator, and a withdrawal-period calculator to find the safe date to slaughter an animal or consume its milk and eggs after treatment, plus a drug interactions checker — to protect food and animal safety.
Data sources
Withdrawal periods — UK Veterinary Medicines Directorate (VMD)
Withdrawal periods (meat, milk, and eggs) are drawn from the Summary of Product Characteristics (SPC) published in the UK directorate's product database. Each value is linked to its original product with a link to its official leaflet for verification.
VMD product database ↗Adverse effects — openFDA (veterinary)
Adverse effects are drawn from the open veterinary drug-event reports in openFDA. The numbers shown represent the report count per ingredient/species, not a severity rate or incidence.
openFDA veterinary API ↗Methodology
- Data is collected automatically from the government sources above, and active ingredients are linked to products, animal species, and their periods.
- Names and terms are standardized to their medical form, while keeping the original English name for reference.
- Active ingredients are classified manually into drug classes based on their actual names; what is hard to classify accurately is placed in an "Other" class rather than forced.
- No numbers are fabricated: if a leaflet does not clearly state a withdrawal period, it is left blank rather than guessed.
Important notice
This site is an educational guidance reference and not a substitute for specialized veterinary consultation. Registered products, their formulations, and their periods may differ between countries.
