What Tramadol Is Used For
Tramadol is a prescription pain medication that may be used as part of a pain-management plan for some dogs and cats. Veterinarians may prescribe it for acute pain, postoperative pain, or as one part of multimodal pain control. It works through weak opioid activity and by affecting serotonin and norepinephrine in the nervous system.
Current veterinary consensus is more cautious than in the past. In dogs, oral tramadol has been deemphasized because studies have not shown reliable benefit for many painful conditions, especially chronic osteoarthritis pain. In cats, tramadol may still have a role in selected cases, although taste and tolerance can be limiting. Your veterinarian may choose it only when it fits your pet's specific condition, health history, and other medications.
Side Effects to Watch For
- Common side effects in dogs can include sedation, decreased appetite, vomiting, diarrhea, constipation, tremors, dizziness, or anxiety.
- Common side effects in cats can include sedation, vomiting, constipation, dilated pupils, uneasy behavior, or drooling if the medication tastes bitter.
- Serious side effects can include seizures, marked agitation, incoordination, very fast heart rate, extreme sleepiness, or signs of serotonin syndrome.
- Risk may be higher in pets with seizure disorders, liver disease, kidney disease, advanced age, debilitation, pregnancy, or lactation.
- Tramadol can interact with several other medications, including some antidepressants, monoamine oxidase inhibitors, other opioids, and drugs that affect serotonin.
Dosing & Administration
Always follow your vet's instructions exactly. Do not change the dose, frequency, or schedule on your own.
Give tramadol only as prescribed for your pet and only in the formulation your veterinarian approved. Some human combination products are dangerous for pets, especially products that contain acetaminophen, which is extremely toxic to cats. Extended-release human products may also be inappropriate for pets unless your veterinarian specifically prescribed them.
You can give missed doses when you remember unless it is close to the next scheduled dose. If it is close to the next dose, skip the missed dose and return to the regular schedule. Never give two doses at once. Contact your veterinarian if your pet spits out the medication, vomits after a dose, seems overly sleepy, or refuses food after starting treatment.
