Bisacodyl, commonly known by the brand name Dulcolax, is a stimulant laxative used by humans to relieve constipation. While it may seem like a harmless over-the-counter medication, it can be dangerous to dogs and cats. Pets that ingest bisacodyl can experience severe abdominal cramping, vomiting, and profuse diarrhea that may lead to dehydration and electrolyte imbalances.
Exposure usually happens when pets chew on or swallow dropped pills, bottles left within reach, or when well-meaning owners give the medication to treat perceived constipation. Because cats and small dogs are particularly sensitive to stimulant laxatives, even a small dose can cause significant distress and may require veterinary treatment.
If you suspect your pet has ingested bisacodyl, contact your veterinarian or a pet poison control center immediately. Do not try to induce vomiting unless specifically instructed by a professional. Bring the medication bottle or packaging with you so your vet can determine the exact dose and ingredients.
To prevent accidental poisoning, store all laxatives and human medications in secure cabinets out of your pet's reach. Never give your pet any medication intended for humans without first consulting your veterinarian. If your pet is constipated, your vet can recommend a safer, species-appropriate treatment plan.

Acetaminophen
Acetaminophen can cause liver injury, gastrointestinal upset, and—at high doses—methemoglobinemia in dogs; do not give without veterinary guidance.
Aspirin
Aspirin is not recommended for routine home use in dogs. It may be prescribed or used short-term under direct veterinary supervision only, because dosing errors or long-term use can cause serious stomach ulcers, bleeding, kidney injury, or liver damage.
Benzocaine
Benzocaine can cause methemoglobinemia and systemic local-anesthetic toxicity if licked or ingested. Even small amounts absorbed through mucous membranes may be dangerous.
Dextromethorphan
Dextromethorphan can cause sedation, agitation, ataxia, vomiting, and tremors in dogs. Combination cold/flu products may contain additional toxic ingredients that increase risk.
Ibuprofen
Ibuprofen is highly toxic to dogs and can cause severe gastrointestinal ulcers, kidney failure, and neurological signs.
Loperamide
Not safe for unsupervised use in dogs. Some dogs tolerate vet-directed doses, but MDR1-mutant/herding breeds are at high risk of sedation, neurotoxicity, and serious CNS/respiratory depression.
