Short answer

Call your vet now. Even a small oral dose can cause gastrointestinal upset like vomiting or diarrhea. More critically, some ear medications contain antibiotics that can harm the kidneys if absorbed systemically. Do not wait to see if she acts sick. Have the medication bottle handy to read the active ingredients to the vet. Do not give her any food or water, and do not attempt to induce vomiting unless your vet explicitly tells you to over the phone. They will advise whether she needs to be seen immediately.

Why fingers are riskier than bottle spills

Medication on human skin gets warmed and partially absorbed into your pores, creating a concentrated residue cats eagerly lick. Unlike a fresh drop from the bottle, this mixture contains skin oils that help the drug penetrate oral tissues faster. Your cat may swallow less volume but absorb more active ingredients.

The 10-minute delay means some drug has already entered the bloodstream through the mouth's thin mucous membranes. Rinsing now won't reverse absorption but may reduce further exposure. Check your cat's tongue for white spots—chemical burns from bitter medications sometimes appear quickly.

The clock started when you saw the lick

Don't wait for vomiting—some cats show neurological signs first. Pupil dilation or twitching whiskers within 30 minutes suggest the drug is affecting the nervous system. Time-stamp these observations; progression speed helps vets gauge toxicity severity.

Mometamax contains mometasone, a steroid that suppresses nausea. Your cat may not vomit despite significant ingestion, giving false reassurance. Instead, watch for rapid breathing or restlessness—early steroid overdose signs often mimic anxiety.

What to do with sticky hands right now

Wash your hands with dish soap (breaks down oils better than hand soap) but avoid alcohol gels—they can drive medication deeper into skin layers. Change clothes if your cat rubbed against them; medication transfers easily to fur during cuddling.

Confine your cat to a small room with water but no food—fasting helps vets assess true vomiting versus regurgitation. Save any hairballs or drool spots for the vet to test. Grab your phone charger—you may be at the clinic longer than expected.

Why ingredient lists confuse more than help

Reading the label yourself often leads to missed risks—generic names hide in small print, and combinations multiply dangers. For example, 'gentamicin sulfate' appears harmless unless you know it's an ototoxic antibiotic. Let the vet decode the chemistry.

Some formulations vary by country. The U.S. version of Mometamax contains gentamicin, while European versions may use framycetin. Your vet needs the lot number to check regional variations affecting treatment plans.
