It is a human medicine. A vet may still prescribe it for a dog or cat, which is legal and common, but it means no company has proved to the FDA that it works or is safe in that animal, and there is no approved animal dose to look up. Ask your vet what they expect it to do and what to watch for.
The label says, word for word:
Human label: "Tramadol hydrochloride tablets are indicated in adults for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate." There is no FDA-approved animal label for tramadol.
Tramadol hydrochloride is contraindicated for: all children younger than 12 years of age; postoperative management in children younger than 18 years of age following tonsillectomy and/or adenoidectomy.
Boxed warning heading: WARNING: ADDICTION, ABUSE, AND MISUSE; RISK EVALUATION AND MITIGATION STRATEGY (REMS); LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; ULTRA-RAPID METABOLISM OF TRAMADOL AND OTHER RISK FACTORS FOR LIFE-THREATENING RESPIRATORY DEPRESSION IN CHILDREN; NEONATAL OPIOID WITHDRAWAL SYNDROME; INTERACTIONS WITH DRUGS AFFECTING CYTOCHROME P450 ISOENZYMES; and RISKS FROM CONCOMITANT…
Tramadol hydrochloride exposes patients and other users to the risks of opioid addiction, abuse and misuse, which can lead to overdose and death.
Serious, life-threatening, or fatal respiratory depression may occur with use of tramadol hydrochloride.
Life-threatening respiratory depression and death have occurred in children who received tramadol.
Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.
Every approved medicine has a field study behind it, and the label prints what happened:
Human label: "The most common incidence of treatment-emergent adverse events (≥15.0%) in patients from clinical trials were dizziness/vertigo, nausea, constipation, headache, somnolence, vomiting and pruritus."
Tramadol is a human prescription drug and a controlled substance: "Tramadol hydrochloride tablets contain tramadol, a Schedule IV controlled substance." (DEA schedule "CIV" on the DailyMed label). No FDA-approved animal drug containing tramadol was found on DailyMed or fda.gov in this research. Veterinarians may prescribe it extra-label under AMDUCA.
The emergency page sorts the signs by how long you have, and the symptom checker asks what you are seeing. Reactions to a medicine can also be reported to the FDA yourself: how to report a problem.
These answers come from the approved label on DailyMed, read on 2 October 2026. Where the label does not say, the answer says so, and the vet or the pharmacist is the one to ask.
The approved use is quoted at the top of this page. The label read for these answers is the one for tramadol hydrochloride tablets, a human prescription medicine. It is approved for adults with pain severe enough to need an opioid painkiller when other treatments are not enough, and it gives no use in dogs or cats, so ask the vet what it has been prescribed for in your pet.
The label gives no time for a pet. In people, it says pain relief begins within about one hour of a dose and peaks at about two to three hours.
The label gives doses for people only, so the amount and the timing for your pet come from the vet. For people, it says the tablets can be taken with or without food. Its Medication Guide tells patients who have been taking tramadol regularly not to stop without talking to their healthcare provider, so ask the vet before you stop it in a pet that has been on it for a while.
The Medication Guide in the label, which is written for people, says: "If you miss a dose, take your next dose at your usual time." It says nothing about dogs or cats, so ask the vet or the pharmacist whether the same goes for your pet.
The studies and the warnings are quoted above. This label is written for people. Its warning for the household is that tramadol swallowed by accident, especially by a child, can be fatal, and its Medication Guide says to get emergency help or call 911 right away after an overdose. The label has no advice on what to watch for in dogs or cats, so ask the vet which signs matter, and call the clinic about any new sign you see in your pet after a dose.
The Medication Guide that is part of the label says to store the tablets where children cannot see or reach them and where other people, including visitors to the home, cannot get at them. The label says tramadol is a Schedule IV controlled substance.
The Medication Guide says to take expired, unwanted or unused tablets to a drug take-back program or to a collector registered with the Drug Enforcement Administration. If neither is available, it says to mix the tablets with dirt, cat litter or coffee grounds, to put the mixture in a sealed plastic bag and to throw the bag in the trash. The FDA's disposal page also puts a take-back option first for most medicines. The Medication Guide says never to give the tablets to anyone else. Do not give leftovers to another pet.
