Rifen Injection for Horses
Rifen has established veterinary applications in horses for certain painful and inflammatory conditions.
The referenced product information lists equine indications including:
- Traumatic lameness
- Arthritis
- Osteitis
- Spavin
- Tendinitis
- Bursitis
- Naviculitis
- Laminitis
- Myositis
- Post-surgical inflammation
- Symptomatic treatment of colic
- Fever
These conditions can significantly affect mobility, comfort and performance.
Veterinary examination is important before treatment because lameness, colic and other clinical signs can have many different causes.
Rifen Injection for Musculoskeletal Pain and Inflammation
Musculoskeletal problems are common concerns in horses, particularly animals involved in athletic activity.
Conditions such as arthritis, tendinitis, bursitis and traumatic lameness may involve pain and inflammation.
Ketoprofen can provide analgesic and anti-inflammatory effects when its use is appropriate.
However, controlling pain does not necessarily resolve the underlying injury. Veterinary diagnosis and appropriate rest, rehabilitation or other treatment may also be required.
Rifen Injection for Equine Colic
The product information identifies Rifen as being indicated for symptomatic therapy of colic in horses.
Colic can range from mild gastrointestinal discomfort to a life-threatening emergency.
A horse showing signs such as:
- Repeated rolling
- Pawing
- Sweating
- Looking at the flank
- Refusing food
- Reduced manure production
- Abdominal discomfort
should receive prompt veterinary assessment.
Pain relief should not delay investigation of the underlying cause.
Rifen Injection for Cattle
Rifen is also authorized for certain indications in cattle.
The referenced product information lists applications involving inflammation, pain or fever, including respiratory disease, mastitis, musculoskeletal disorders and injuries.
For cattle, appropriate treatment depends on the animal’s condition, diagnosis and applicable local product authorization.
Rifen Injection for Pigs
Rifen 100mg/mL is also authorized for pigs in the referenced European product information.
The exact approved indications and administration route should be confirmed against the product information applicable to the country where the medicine is being used.
How Ketoprofen Works
Ketoprofen is an NSAID that provides analgesic and anti-inflammatory activity.
By reducing pathways involved in inflammatory mediator production, ketoprofen can help reduce pain and inflammation associated with appropriate veterinary conditions.
Because NSAIDs can affect gastrointestinal, renal and other physiological systems, appropriate veterinary assessment is important before treatment.
Rifen Injection 100mL Dosage and Administration
The dosage and route must follow the current product label for the specific market.
For the referenced European formulation, the manufacturer’s information states for horses:
2.2mg ketoprofen/kg body weight once daily intravenously for 3–5 consecutive days, equivalent to 1mL per 45kg body weight. For colic, one injection is generally sufficient, with further treatment requiring reassessment.
The official UK product information specifies intravenous administration for horses, while cattle and pigs have different routes depending on the species.
Do not apply dosing instructions from another ketoprofen formulation without confirming they correspond to the exact Rifen product.
Important Safety Information
Rifen should be used carefully because ketoprofen is an NSAID.
Before treatment, the veterinarian may consider:
- Hydration status
- Kidney function
- Liver health
- Gastrointestinal health
- Existing disease
- Age
- Pregnancy
- Other medicines
- Previous reactions to NSAIDs
The referenced product information states that Rifen should not be used in pregnant mares.
Important Equine Considerations
Pain relief can make an animal appear more comfortable without resolving the underlying problem.
This is particularly important with:
- Colic
- Severe lameness
- Laminitis
- Traumatic injuries
- Postoperative complications
Veterinary reassessment should be obtained when clinical signs persist or worsen.

Rifen and Other Medicines
Tell the veterinarian about all medicines currently being administered.
This includes:
- Other NSAIDs
- Corticosteroids
- Analgesics
- Antibiotics
- Gastrointestinal medicines
- Supplements
- Other injectable products
Avoid combining NSAIDs or changing from one NSAID to another without veterinary direction.
Rifen Withdrawal Periods
Withdrawal requirements are particularly important when Rifen is used in food-producing animals.
For the referenced UK authorization, the withdrawal periods are:
| Species | Route | Meat & Offal |
|---|---|---|
| Horse | IV | 1 day |
| Cattle | IV | 1 day |
| Cattle | Deep IM | 3 days |
| Pig | Deep IM | 4 days |
Cattle milk has a zero-hour withdrawal period under the referenced UK product information, while the product is not authorized for mares producing milk for human consumption.
Always follow the withdrawal period on the current local label because regulatory requirements can differ by jurisdiction.

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’.

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:/
