Ketoprofen and Veterinary Pain Management
Ketoprofen belongs to the NSAID class and is used in veterinary medicine to help manage pain and inflammation when clinically appropriate.
Inflammation is part of the body’s response to injury or disease. Prostaglandins contribute to inflammatory signaling, pain and fever. By reducing prostaglandin production, ketoprofen can help reduce associated clinical signs.
However, prostaglandins also contribute to normal gastrointestinal, kidney and other physiological functions. Appropriate veterinary assessment is therefore important when using an NSAID.
Rifen Injection for Horses and Livestock
Rifen Injection 100mL may be encountered in veterinary settings involving horses or livestock, depending on the specific product authorization.
Potential veterinary applications for ketoprofen products can include management of:
- Musculoskeletal pain
- Inflammatory conditions
- Joint-related discomfort
- Fever
- Postoperative pain
- Soft-tissue inflammation
The exact indication depends on the product label, species and local regulatory authorization.
Veterinary assessment is recommended before treating unexplained pain or fever because these signs can be caused by infections, injuries, metabolic disorders or other conditions requiring specific treatment.
Common Veterinary Applications
A veterinarian may evaluate an animal for NSAID therapy when pain or inflammation is associated with a diagnosed condition.
Potential signs requiring evaluation include:
- Lameness
- Joint swelling
- Stiffness
- Reduced mobility
- Fever
- Postoperative discomfort
- Reduced appetite
- Behavioral changes
Rifen Injection may help control symptoms when appropriately indicated, but an NSAID does not necessarily address the underlying cause of disease.
Rifen Injection 100mL Dosage and Administration
There is no universal dosage for every Rifen Injection 100mL product.
The appropriate dosage depends on:
- Exact formulation
- Ketoprofen concentration
- Species
- Body weight
- Diagnosis
- Route
- Frequency
- Treatment duration
- Kidney and liver function
- Other medicines being administered
The current manufacturer’s label and veterinarian should determine the appropriate dosage.
The 100mL bottle is the package size, not a recommended dose.
Do not increase the amount, frequency or treatment duration without professional veterinary advice.
Safety and Precautions
NSAIDs can cause gastrointestinal, kidney and liver adverse effects, particularly in susceptible animals.
Veterinary advice is especially important when an animal is:
- Dehydrated
- Hypovolemic
- Elderly
- Very young
- Pregnant
- Suffering from kidney disease
- Suffering from liver disease
- Suffering from gastrointestinal disease
- Receiving another NSAID
- Receiving corticosteroids
Potential warning signs may include:
- Reduced appetite
- Vomiting
- Diarrhea
- Dark or abnormal feces
- Abdominal discomfort
- Changes in thirst
- Changes in urination
- Depression
- Unexpected weakness
If an adverse reaction is suspected, contact a veterinarian promptly.
Rifen and Other NSAIDs
Rifen Injection should not be combined with other NSAIDs unless specifically directed by a veterinarian.
Examples of NSAIDs that may require consideration include:
- Phenylbutazone
- Flunixin
- Meloxicam
- Carprofen
- Firocoxib
- Aspirin
Corticosteroids may also increase the risk of gastrointestinal complications when used with NSAIDs.
Always provide the veterinarian with a complete list of medicines and supplements the animal is receiving.
Food-Animal Considerations
If Rifen Injection 100mL is being considered for cattle, pigs or another food-producing species, withdrawal requirements must be confirmed for the exact product.
Withdrawal periods may vary according to:
- Species
- Product
- Dose
- Route
- Country
- Regulatory authorization
Never assume that a withdrawal period for one ketoprofen product applies to another.
Follow the approved product label and applicable food-safety regulations.
Competition Animal Considerations
Owners of racehorses and competition animals should check current medication rules before using Rifen Injection.
Ketoprofen and other NSAIDs may be subject to restrictions, detection periods or prohibited-substance rules depending on the sport and jurisdiction.
Before treatment, verify:
- Competition regulations
- Prohibited substances
- Detection requirements
- Withdrawal recommendations
- Product-specific ingredients
Commercial availability does not mean a product is automatically permitted during competition.
Storage and Handling
Store Rifen Injection 100mL according to the manufacturer’s current instructions.
Before use, inspect the container for:
- Damage
- Leakage
- Contamination
- Expiration
- Unusual changes in appearance
Use appropriate sterile procedures when administering injectable veterinary products and dispose of needles and sharps responsibly.

Uses
Horse
Diseases affecting the osteoarticular and muscular-skeletal system associated with acute pain and inflammation:
– Lameness of traumatic origin
– Arthritis
– Osteitis, spavin
– Tendinitis, bursitis
– Naviculitis
– Laminitis
– Myositis
Ketoprofen is also indicated for post-surgical inflammation, symptomatic therapy of colic and fever.
Cattle
Diseases associated with inflammation, pain or fever:
– Respiratory diseases
– Mastitis
– Osteoarticular and muscular-skeletal disorders such as lameness, arthritis and to ease uprise post parturition
– Injuries
Swine
Diseases associated with inflammation, pain or fever:
– Treatment associated with the Postpartum Dysgalactia Syndrome/Mastitis Metritis Agalactia (MMA) Syndrome
– Respiratory tract infections
– Symptomatic treatment of fever
For the short-term relief of post operative pain associated with minor soft tissue surgery such as castration in piglets.
Where necessary ketoprofen should be combined with appropriate antimicrobial therapy.
Dosage and administration
Horse:
2.2 mg ketoprofen/kg body weight/day intravenously once daily, for up to 3 to 5 consecutive days, i.e. 1 ml per 45 kg body weight.
In order to treat colic one injection is normally sufficient. A second administration of ketoprofen requires a reassessment of the patient’s clinical status. See below ‘Advice on correct administration’.
Cattle:
3 mg ketoprofen/kg body weight/day intravenously or deep intramuscularly once daily for up to 3 consecutive days, i.e. 3 ml per 100 kg body weight.
Swine:Rifen 100ml
Advice on correct administration
Avoid intra-arterial injection. Do not exceed recommended dose or period of treatment. Special care should be taken when administering the product to animals with severe dehydration, hypovolaemia and hypotension as there is a potential risk of increased renal toxicity.
The use of ketoprofen is not recommended in foals under the age of 15 days. Use in animals less than 6 weeks of age or in aged animals may involve additional risk. If such use cannot be avoided, animals may require a reduced dosage and careful management. See ‘use during pregnancy and lactation’ regarding the use of the product in pregnant mares and sows.
Sufficient drinking water must be supplied at all times during treatment.
In colic, a subsequent dose may be given only after a thorough re-examination.
Contra-indications, warnings, etc
Do not use in case of hypersensitivity to the active substance, or to any of the excipients. Do not use in animals suffering from gastrointestinal lesions, haemorrhagic diathesis, impaired hepatic, renal or cardiac function. Do not use with other NSAID drugs concurrently or within 24 hours of each other.
Adverse reactions
Due to the mechanism of action of NSAIDs (inhibition of prostaglandin synthesis), gastric and intestinal irritation or ulceration or renal intolerance may occur even after appropriate use.
Intramuscular injections may occasionally cause transient irritation.
Repeated administration to swine may result in reversible inappetence.
Allergic reactions may occur very rarely. In this case the treatment should be stopped.
If you notice any serious effects or other effects not mentioned in this leaflet, please inform your veterinary surgeon.
Special warnings
Treatment of piglets with ketoprofen before castration reduces post operative pain for 1 hour. To obtain pain relief during surgery co-medication with an appropriate anaesthetic/sedative is needed.
Use during pregnancy and lactation
Can be used during pregnancy in cattle but should not be used in pregnant mares. In absence of studies on swine use only according to the benefit/risk assessment by the responsible veterinarian.
Can be used in lactating cows.
Interaction with other medicinal products
The product must not be administered in conjunction with, or within 24 hours of administration of other NSAIDs and glucocorticoids. Concurrent administration of diuretics, nephrotoxic drugs and anticoagulative drugs should be avoided.
Ketoprofen is highly bound to plasma proteins and may displace or be displaced by other highly protein bound medicines, such as anticoagulants with the possibility of consequent toxic effects due to the unbound fraction of the drug. Due to the fact that ketoprofen may inhibit platelet aggregation and cause gastrointestinal ulceration, it should not be used with other medicines that have the same profile of adverse drug reactions.
Overdose
Overdose with NSAIDs can lead to gastrointestinal ulceration, loss of proteins, hepatic and renal impairment.
Early signs of toxicity include loss of appetite and pasty faeces or diarrhoea. If overdose symptoms are observed, symptomatic treatment should be initiated.
Incompatibilities
In the absence of compatibility studies, this veterinary medicinal product must not be mixed with other veterinary medicinal products.
To the user
In case of accidental self-injection, seek medical advice immediately and show the package leaflet or the label to the physician. People with known hypersensitivity to ketoprofen or benzyl alcohol should avoid contact with the veterinary medicinal product.
Avoid splashes on the skin and eyes. Rinse thoroughly with water should this occur. If irritation persists seek medical advice. Wash hands after use.http:/
