Bleeder Stop Vitamin Combo (Vitamin C + L-Histidine + L-Arginine + L-Lysine + Vitamin B-6) Paste

Paste medications are thick and sticky, usually given by mouth using a syringe or tube. They’re often used for dewormers or other oral meds in horses, dogs, and cats. The key is to aim for the back of the mouth so your pet swallows the paste instead of spitting it out.

For Horses:

1. Set the dose on the syringe if it has markings (usually based on weight).
2. Stand beside your horse, not in front, and have someone hold them if possible.
3. Gently insert your thumb into the side of the horse’s mouth (between the teeth) to open it.
4. Insert the syringe into that gap and squirt the paste toward the back of the tongue.
5. Lift the horse’s head slightly and encourage swallowing by stroking the throat or gently blowing on the nostrils.
6. Watch for licking or chewing—that means they swallowed. If paste spills out, check how much was lost and contact your vet if unsure.
7. You can offer a little water afterward and reward them with a treat like a carrot if allowed.

For Dogs & Cats:

1. Gently open your pet’s mouth or slip the syringe into the side of it.
2. Aim toward the back of the tongue and squirt the paste in.
3. Hold the mouth closed briefly, and rub the throat or blow gently on the nose to encourage swallowing.
4. Give praise or a treat afterward to make it a positive experience.

Aftercare:

1. Wipe your pet’s mouth if needed.
2. Clean or recap the syringe as instructed.
3. Store the tube according to label directions.

Tip: Paste can feel weird to pets at first. For horses, try giving applesauce by syringe ahead of time so they get used to the sensation.

This is a compounded preparation combining the active ingredients listed in the product name. In compounding practice, clinicians may consider a multi-ingredient preparation like this to address more than one aspect of a patient's physiology at once. Your veterinarian determines whether it is appropriate for your animal.

At a pharmacological level, the components of this combo act through several synergistic pathways to address vascular and cellular health. Vitamin C and Vitamin B-6 function as vital cofactors in collagen synthesis and the metabolic processing of amino acids, which are essential for maintaining the structural strength of blood vessel walls. The amino acids L-arginine, L-histidine and L-lysine serve as building blocks for protein synthesis and act as precursors to nitric oxide, a molecule that influences vascular tone and blood flow dynamics. This parenteral route allows these nutrients to bypass the digestive tract, ensuring immediate availability for the horse’s metabolic requirements during critical performance windows. Your veterinarian will determine if this specific combination is appropriate based on your horse's weight, activity level and specific clinical history.

This description reflects the general pharmacology of the active ingredient's drug class; your veterinarian determines whether this approach is appropriate for your animal.

Commonly observed effects of bleeder stop vitamin combo administration include localized site irritation at the point of injection or transient behavioral changes as the body adjusts to the infusion. Because this preparation contains concentrated vitamins and amino acids, it is typically administered via slow intravenous injection under professional oversight to minimize the risk of acute physiological shifts. Owners should monitor for any signs of restlessness, sweating or increased respiratory rate shortly after administration. If you observe persistent swelling at the injection site or signs of physical distress, contact your veterinarian promptly.

This medication is typically used with caution in horses with known kidney or liver impairment, as these organs are responsible for the metabolic processing and excretion of concentrated nutrients. It is also carefully evaluated in patients with a history of hypersensitivity to injectable vitamin products. Before starting a protocol involving this vitamin combo, ensure your veterinarian has a complete history of all other prescriptions and supplements your horse is receiving to avoid potential metabolic imbalances. Your veterinarian is the right person to design a comprehensive management approach and determine the appropriate timing of administration relative to your horse’s performance schedule.
