A prescription NSAID exposure needs prompt veterinary or poison-control assessment even when a dog looks normal. Celecoxib, ketorolac, diclofenac, indomethacin, piroxicam, and etodolac differ in potency and formulation, but all require the exact product, strength, amount, time, and the dog's medication history—not a home dose comparison.
Identify the medicine before interpreting the signs
Start with the active ingredient, not the color of the tablet or the reason a person takes it. Drugs that share a cabinet, a brand family, or a general purpose can act on completely different body systems. Find the original bottle or pharmacy record, and do not rely on a pill-identification guess when the package can be recovered.
Call a veterinarian, emergency hospital, or animal poison-control service promptly with the exact name, strength, formulation, possible amount, time, and the dog's weight. A normal appearance immediately after access is not a reason to wait: the useful assessment starts with exposure facts, and some formulations release medicine over many hours.
| Medicine or subgroup | Why the distinction matters | Details to report |
|---|---|---|
| Celecoxib (Celebrex) | A COX-2-selective human NSAID, often in capsules; selectivity does not make an overdose dog-safe. | Capsule strength, count missing, time |
| Ketorolac (Toradol) | A potent prescription NSAID found as tablets, injections, or eye products. | Route/form, strength, possible amount |
| Diclofenac (Voltaren) | Often a gel, patch, or topical solution; licking skin or chewing a tube can be meaningful. | Concentration, tube weight/amount, contact route |
| Indomethacin, piroxicam, etodolac | Different half-lives and veterinary uses mean one cannot stand in for another. | Exact ingredient, strength, amount, other NSAIDs |
What this medication family changes in the body
NSAIDs reduce prostaglandin production. Prostaglandins participate in pain and inflammation, but they also help protect the gastrointestinal lining and kidney blood flow. Merck's analgesic-toxicology chapter explains why overdose can produce ulceration and kidney injury, especially when dehydration or another interacting medicine is present.
A product being prescription-only, selective, topical, or sometimes used by veterinarians does not answer an accidental exposure. The FDA tells owners not to give a human pain reliever or medicine left from another animal without veterinary direction. Intended treatment and unplanned ingestion are different clinical questions.
What an owner may notice—and what can stay hidden
Vomiting, loss of appetite, abdominal discomfort, diarrhea, blood in vomit, or black tarry stool can reflect gastrointestinal injury. Increased thirst or urination, reduced urination, lethargy, weakness, or later laboratory changes can accompany kidney injury. Serious damage may start before an owner can see it.
Topical products create two routes: oral ingestion from the tube or treated skin, and eye or skin contact. Prevent further licking without applying a new chemical, preserve the label, and report where the product was used. If a patch or tube was swallowed, packaging obstruction is a separate concern.
Why two apparently similar exposures can get different advice
Risk changes with the molecule, strength, amount, formulation, timing, hydration, and preexisting kidney or gastrointestinal disease. Steroids, another NSAID, anticoagulants, and some kidney or blood-pressure medicines may change the assessment. List all of them rather than naming only the missing drug.
Dog-prescribed NSAIDs also require an overdose call. Do not use a previous instruction or compare milligrams across drugs. If the dog received an extra scheduled dose, contact the prescribing practice before the next dose and report the exact dosing times.
- The active ingredient and tablet or liquid strength, including every ingredient in a combination product.
- Immediate-release, delayed-release, extended-release, patch, cream, pen, or other formulation wording.
- The maximum that could be missing, the earliest and latest possible access time, and whether more than one dog had access.
- The dog's current weight, age, symptoms, heart or kidney disease, diabetes, and every prescription or supplement already given.
- Chewed plastic, foil, glass, needles, cartridges, or other packaging that creates an injury or obstruction question separate from the drug.
Build a useful exposure record while you call
Photograph the front label, prescription panel, active ingredients, and remaining contents. Count what remains only if that can be done safely; report an honest range when the original count is uncertain. The poison-control call checklist can keep those details in one place without delaying the call.
Describe observations instead of conclusions: write “stumbled twice at 2:10” rather than “overdosed,” and record vomiting, urination, thirst, breathing, alertness, tremors, gum color, and changes in sequence. Merck's poisoning-diagnosis guidance emphasizes the exposure history and order of signs because those facts help a clinician choose monitoring and tests.
This guide complements pain medications toxic to dogs, which covers the common OTC painkillers. The pages for celecoxib, ketorolac, and less familiar prescription products preserve the active-ingredient distinction.
Why this guide gives no dose or home antidote
A toxicity threshold copied from one drug cannot be transferred to another member of the family, and a number without formulation, patient history, and timing can encourage a dangerous delay. This page therefore does not calculate a “safe” amount, diagnose poisoning, or prescribe a home treatment.
Do not induce vomiting, give activated charcoal, force food or water, or add another medicine unless the veterinary professional managing this exact exposure directs it. Vomiting can be unsafe when a dog is already sleepy, agitated, weak, seizuring, unable to swallow normally, or exposed to a formulation that changes aspiration risk. Use the first 10 minutes guide for safe information-gathering steps while help is arranged.
Prevent the second exposure
FDA advises keeping medicines in their original, labeled containers and in genuinely secure storage. Countertops, bedside tables, handbags, weekly organizers, and parcels are common access points because a dog can pull down, crush, or chew containers that seem closed. Separate human and animal medicines, and do not pre-sort pills into an unlabeled bag when a labeled container can travel with them.
After the immediate case is handled, reconcile the remaining medication with the pharmacy record and clean up fragments where pets cannot reach them. Use a take-back or label-directed disposal route, secure sharps in an appropriate container, and give caregivers a written medication handover. Prevention is part of the medical record: knowing exactly how access occurred makes the next container easier to protect.

Frequently asked questions
Is celecoxib safer because it is COX-2 selective?
Do not use selectivity as a home safety rule. An unintended exposure still requires the exact strength, amount, timing, patient history, and other medicines to be assessed by a veterinarian or poison specialist.
Can licking diclofenac gel matter?
Yes. A topical medicine is still an active drug, and repeated licking or chewing a tube can create an oral exposure. Report the concentration, amount missing, treated area, and whether packaging was swallowed.
Why call before vomiting or black stool appears?
Gastrointestinal and kidney injury can begin before visible signs. Early product-specific assessment may affect what monitoring or treatment is useful, so waiting for illness can lose time.
Should I wait for symptoms if my dog looks normal?
No. Call with the exact product and exposure estimate. Some effects are delayed, and early decisions depend on the drug, formulation, possible amount, time, weight, and current condition rather than on visible illness alone.
Can I make my dog vomit after a pill exposure?
Only if the veterinarian or animal poison specialist handling the case specifically directs it. Neurologic depression, agitation, swallowing difficulty, the formulation, and the time since access can all make vomiting unsafe or unhelpful.
What if I cannot tell how many tablets are missing?
Report the uncertainty rather than choosing a reassuring number. Bring the bottle, remaining pills, refill date, prescribed schedule, possible access window, dog's weight, symptoms, and information about any other pet that could have reached it.
