Short answer

The vet will likely run blood tests to check his kidney values and red blood cell count, since NSAIDs can cause kidney failure and stomach ulcers. They might also do a urine test to see how well his kidneys are concentrating urine. You'll need to watch for any vomiting, especially if it looks like coffee grounds, or if he drinks much more water than usual. Bring him back for a recheck if he seems lethargic or stops eating — those are signs the treatment needs adjusting.

Why Human Pain Creams are Toxic to Pets

Many over-the-counter pain creams contain non-steroidal anti-inflammatory drugs (NSAIDs) like diclofenac or ibuprofen, which are extremely toxic to pets and can cause acute kidney failure.

Capsaicin-based creams (from chili peppers) cause intense burning, drooling, and gastrointestinal upset.

Even small amounts licked off an owner's skin or from a tube can be dangerous, especially for cats.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Signs to watch for

  • Excessive drooling and pawing at the mouth
  • Vomiting, possibly with blood
  • Loss of appetite and lethargy
  • Increased thirst and urination (signs of kidney issues)
  • Abdominal pain
  • Redness and irritation of the skin, mouth, or eyes

What to do right now

  1. Call your vet or a poison helpline immediately.
  2. If the cream is on your pet's fur or skin, put on gloves and wash the area thoroughly with mild dish soap and water to prevent further licking.
  3. Do NOT induce vomiting.
  4. Your vet will provide supportive care, which may include intravenous fluids to protect the kidneys and medications for stomach ulcers.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
