© medsdog.com
Banamine Dosage For Dogs (flunixin meglumine) is a non-steroidal anti-inflammatory drug (NSAID) which acts by blocking the production of inflammatory chemicals within the body, thereby reducing the pain, inflammation and fever. Although it can be used in horses and cattle, veterinarians may prescribe this off-label for dogs in very limited situations, such as when a dog has severe musculoskeletal pain, specific inflammatory disorders or fever for which the potential benefits outweigh the risks.
Banamine for dogs is not regarded as a “routine” NSAID for dogs as there are safer canine NSAIDs that are sometimes preferred, and veterinary supervision is necessary. Banamine dosage for dogs by weight is discussed in this guide, which includes information on how it works, dosage forms (50 mg/mL injectable solution), dosage calculations, potential benefits, side effects, drug interactions, monitoring requirements, and important safety information to help owners understand when it may be appropriate and how to use it as safely as possible.

What Is Banamine® (Flunixin Meglumine)?
The brand name Banamine® refers to the drug flunixin meglumine for dogs which is a non-selective non-steroidal anti-inflammatory drug (NSAID) that inhibits the enzymes COX-1 and COX-2 that produce the substances which cause pain, inflammation and fever.

This NSAID inhibits the synthesis of prostaglandins which helps to minimise redness, swelling, heat and pain caused by tissue injury and be in addition is antipyretic (fever reducing).
It usually takes about 15 minutes after the injection into the vein (intravenous or IV) or 1-2 hours after the injection into the muscle (intramuscular or IM) to take effect after it is given.

Though it may be very effective in certain carefully selected cases, it is not a first-line NSAID for dogs and should always be prescribed by a veterinarian, due to potentially serious gastrointestinal and renal side effects.
Treatment is successful only when the correct dosage is used, therapy is limited to the shortest effective period (usually no more than three days), it is not combined with another NSAID or corticosteroids and monitored by watching your dog’s appetite, hydration, stool and overall condition.

Do not administer Banamine dosage for dogs without veterinary advice or to a livestock product. As long as it is used responsibly and under professional supervision, Banamine can be a part of the solution to treating acute pain and inflammation, without causing complications.
