Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

Alleviation of pain and inflammation in acute and chronic musculo-skeletal disorders
in cats.
Guinea pigs:
Alleviation of mild to moderate post-operative pain associated with soft tissue surgery
such as male
castration.

Particular care should be taken with regard to the accuracy of dosing. The
recommended dose should not be exceeded.
Dosage
Cats:
Post-operative pain and inflammation following surgical procedures:
After initial treatment with a suitable injectable formulation of meloxicam authorised
for cats, continue treatment 24 hours later with Metaxx 0.5 mg/ml oral suspension for
cats at a dosage of 0.05 mg meloxicam/kg body weight, i.e. 0.1 mL/kg body weight.
The oral follow-up dose may be administered once daily (at 24-hour intervals) for up
to four days.
Acute musculo-skeletal disorders:
Initial treatment is a single oral dose of 0.2 mg meloxicam/kg body weight,i.e. 0.4
mL/kg body weight on the first day. Treatment is to be continued once daily by oral
administration (at 24-hour intervals) at a dose of 0.05 mg meloxicam/kg body weight,
i.e. 0.1 mL/kg body weight for as long as acute pain and inflammation persist.
Chronic musculo-skeletal disorders:
Initial treatment is a single oral dose of 0.1 mg meloxicam/kg body weight, i.e. 0.2
mL/kg body weight on the first day. Treatment is to be continued once daily by oral
administration (at 24-hour intervals) at a maintenance dose of 0.05 mg meloxicam/kg
body weight, i.e. 0.1 mL/kg body weight. A clinical response is normally seen within 7
days. Treatment should be discontinued after 14 days at the latest if no clinical
improvement is apparent.
Dosage
Guinea pigs:
Post-operative pain associated with soft tissue surgery:
Initial treatment is a single oral dose of 0.2 mg meloxicam/kg body weight, i.e. 0.4
mL/kg body weight on day 1 (pre-surgery).
Treatment is to be continued once daily by oral administration (at 24-hours intervals)
at a dose of 0.1 mg meloxicam/kg body weight, i.e. 0.2 mL/kg body weight on day 2
to day 3 (post-surgery).
The dose can, at the discretion of the veterinarian, be titrated up to 0.5 mg/kg body
weight, i.e. 1 mL/kg body weight in individual cases. The safety of doses exceeding
0.6 mg/kg body weight has, however, not been evaluated in guinea pigs.

Cats and guinea pigs:
If adverse reactions occur, treatment should be discontinued and the advice of a
veterinarian should be
sought.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.

None.

Special precautions for safe use in the target species:
Avoid use in any dehydrated, hypovolaemic or hypotensive animal, as there is a
potential risk of renal
toxicity.
Post-operative use in cats and guinea pigs:
In case additional pain relief is required, multimodal pain therapy should be
considered.
Chronic musculoskeletal disorders in cats:
Response to long-term therapy should be monitored at regular intervals by a
veterinary surgeon.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Meloxicam and other non-steroidal anti-inflammatory drugs (NSAIDs) may cause
hypersensitivity reactions. People with known hypersensitivity to NSAIDs should
avoid contact with the veterinary medicinal product. Wash hands after use.
Accidental ingestion of the product may cause gastrointestinal effects, such as
nausea and gastric pain. Avoid accidental ingestion by children. Do not leave the
filled syringe unattended. Any uneaten medicated food must be disposed of
immediately and the bowl washed thoroughly. In case of accidental ingestion, seek
medical advice immediately and show the package leaflet or the label to the
physician.
Special precautions for the protection of the environment:
Not applicable.

Other NSAIDs, diuretics, anticoagulants, aminoglycoside antibiotics and substances
with high protein binding may compete for binding and thus lead to toxic effects.
Meloxicam must not be administered in conjunction with other NSAIDs or
glucocorticosteroids. Concurrent administration of potential nephrotoxic drugs should
be avoided.
In cats, pre-treatment with anti-inflammatory substances other than meloxicam at a
single dose of 0.2 mg/kg may result in additional or increased adverse effects and
accordingly a treatment-free period with such veterinary medicinal products should
be observed for at least 24 hours before commencement of treatment. The
treatment-free period, however, should take into account the pharmacological
properties of the products used previously.
