Prevail (Flunixin Meglumine) Injectable Solution
Prevail is an FDA-approved product containing flunixin meglumine, for veterinary use. Available by prescription.
Veterinarians most commonly consider Prevail when a patient is presented with signs of visceral discomfort, such as those associated with equine colic or during localized tissue stress related to orthopedic disorders. It is frequently a point of discussion for managing systemic inflammatory responses and is often utilized as part of a pain management strategy following surgical procedures. By modulating the biochemical environment at the site of inflammation, your veterinarian can manage the patient's physiological state during acute or chronic challenges.
At a pharmacological level, flunixin meglumine acts as a non-selective inhibitor of the cyclooxygenase (COX) enzymes. By inhibiting both COX-1 and COX-2, the medication disrupts the biosynthesis of prostaglandins, which are the primary lipid signaling molecules responsible for mediating inflammation, fever and sensitivity to discomfort. Prevail is characterized by its significant potency—often cited as being more potent than aspirin in specific species—and its relatively rapid onset of activity. Your veterinarian will determine whether Prevail is appropriate based on the species, weight, health history and the specific clinical nature of the patient’s presentation.

Commonly observed effects of Prevail administration include localized irritation at the site of injection or mild gastrointestinal changes such as decreased appetite. In equine patients, prolonged use or high doses are associated with gastric or colonic ulceration and potential shifts in kidney health. Owners should watch for subtle behavioral shifts such as "girthiness," teeth grinding or changes in manure consistency. Because flunixin meglumine can mask clinical signs of a worsening condition, particularly in colic cases, your veterinarian will provide specific guidance on monitoring. If you observe dark or tarry stools, persistent lethargy or signs of physical distress, contact your veterinarian promptly.
This medication is typically used with extra caution or avoided in animals with known renal or hepatic impairment or those with active gastrointestinal ulceration. It is also carefully evaluated in breeding, pregnant or lactating animals, as the safety profile for developing foals and livestock offspring is a point of ongoing clinical awareness. Before starting a protocol, ensure your veterinarian has a complete history of all other prescriptions and supplements your pet is receiving, as it may interact with other NSAIDs or corticosteroids. Your veterinarian is the right person to design a comprehensive monitoring plan and provide guidance on the necessary duration of use to ensure the management approach remains suitable for your animal’s individual status.
Yes. Prevail is a prescription medication and can only be dispensed by a licensed pharmacy upon receipt of a valid authorization from a licensed veterinarian. Mixlab verifies all authorizations before any medication is prepared or shipped to your farm or stable.
Yes. While Prevail is available as a commercial injectable solution, Mixlab can compound the active ingredient, flunixin meglumine, into alternative strengths or flavored dosage forms—such as oral liquids, powders or pastes—if your veterinarian determines a customized preparation better suits your animal's needs. The decision between a commercial and compounded product rests with the prescribing veterinarian.
Veterinarians discuss Prevail in the context of colic because of its specific activity in managing visceral inflammation and discomfort associated with the gastrointestinal tract. It is often part of a comprehensive management approach while the underlying cause of the distress is being evaluated and addressed.
Owners should monitor for signs such as a lack of interest in feed, behavioral changes during tacking or the appearance of dark, tarry manure. Because this medication can influence the protective lining of the stomach, regular communication with your veterinarian is essential to ensure the management plan remains safe for your horse.
