Dairy Cattle Prescription Medications
Every quarter counts on a dairy. When mastitis shows up or it's time to dry off a cow, you need the right tube on hand and a clear idea of when that milk can ship again. Valley Vet Supply was started in 1985 by two veterinarians who treated cattle, horses, and pets out of a mixed-animal clinic in Marysville, Kansas, so dairy work is familiar ground for us. This collection carries the dairy cattle prescription medication your herd veterinarian prescribes, from lactating cow tubes to dry cow therapy.
Common Dairy Rx Categories
Lactating cow tubes treat clinical mastitis while the cow stays in the milking string. Today (Cephapirin Sodium) One-Day Treatment Lactating Cows delivers 200 mg of cephapirin per 10 ml syringe. Infuse each infected quarter right after milking and repeat 12 hours later. Spectramast LC Lactating Cow Formula for Dairy Cattle uses 125 mg of ceftiofur in a cottonseed oil base, given once a day for 2 days, and its label allows once-daily extended therapy for up to 8 days in a row.
Dry cow therapy goes in at drying off. Tomorrow (Cephapirin Benzathine) Dry Cow Mastitis Treatment pairs 300 mg of cephapirin per syringe with a peanut oil gel and an Opti-Sert protective cap for partial or full insertion. Use one syringe per quarter, no later than 30 days before calving.
Ordering and Using Dairy Rx Medication
Working with Your Herd Veterinarian
Every product here requires a valid prescription. You'll be asked for animal and veterinarian details at checkout, and our pharmacy team works with your vet to verify the prescription before the order ships. A written mastitis protocol from your herd veterinarian, covering which tube to use for which case, makes ordering faster and keeps everyone on the milking crew consistent.
Milk Withdrawal Times and Treatment Records
Withdrawal periods differ by product, so write them down. Log the cow ID, quarter treated, product, date, and the day her milk can go back in the tank. Mark treated cows with leg bands or tail chalk so nobody milks them into the bulk tank by mistake. Need a broader lineup of dairy cow antibiotics? Browse Livestock Antibiotics.
Frequently Asked Questions
Do I need a prescription for mastitis treatment?
For the intramammary antibiotics in this collection, yes. Each listing is marked Valid Prescription Required, and cephapirin tubes like Today and Tomorrow moved from over-the-counter to prescription status when the FDA's GFI 263 took effect in June 2023. Spectramast LC was already a prescription product before that change.
How long is the milk withdrawal after antibiotic treatment?
It depends on the product. The Today label says not to use milk for 96 hours after the last treatment, while Spectramast LC calls for 72 hours. Tomorrow is a dry cow product, so its 72-hour milk withhold is counted from calving. Always confirm the milk withdrawal time on the label and in your vet's protocol.
Can I order dairy Rx medication online?
Yes. Add the product to your cart and enter your animal and veterinarian information at checkout. Each listing shows an estimated ship time, so order ahead of your dry-off dates. Auto-Ship can also keep tubes you use every month from running short.
