This article will explore the effects of the top 18 human medicines on dogs and provide safe alternatives, both over-the-counter and prescription.

1. Tylenol (Acetaminophen): NO

Effect on Dogs: Acetaminophen is highly toxic to dogs. It can cause liver damage, red blood cell destruction, and even death. Symptoms of toxicity include vomiting, lethargy, difficulty breathing, and a swollen face or paws.

2. Motrin (Ibuprofen): NO

Effect on Dogs: Ibuprofen can cause severe gastrointestinal ulcers, kidney failure, and neurological issues. Signs of toxicity include vomiting, diarrhea, abdominal pain, and weakness.

3. Pseudoephedrine (Sudafed): NO

Effect on Dogs: Pseudoephedrine is highly toxic to dogs and can cause hyperactivity, elevated heart rate, high blood pressure, seizures, and death.

4. Xylitol (found in sugar-free medications and products): NO

Effect on Dogs: Xylitol is extremely toxic to dogs, causing rapid insulin release, hypoglycemia, liver failure, and even death. Symptoms include vomiting, loss of coordination, and seizures.

5. Naproxen (Aleve): NO

Effect on Dogs: These ingredients can cause central nervous system depression, high blood pressure, and potentially life-threatening symptoms like seizures and coma.

7. Beta Blockers (e.g., Metoprolol, Atenolol): NO

Effect on Dogs: Beta blockers can cause severe drops in blood pressure and heart rate, leading to lethargy, collapse, and potentially life-threatening heart issues.

8. ACE Inhibitors (e.g., Lisinopril, Enalapril):  NO

Effect on Dogs: While sometimes prescribed by vets for specific conditions, incorrect dosing can cause low blood pressure, kidney failure, and elevated potassium levels.

9. ADHD Medications (e.g., Adderall, Ritalin): NO

Effect on Dogs: These medications can cause hyperactivity, tremors, seizures, elevated heart rate, and potentially fatal cardiac issues.

10. Thyroid Medications (e.g., Levothyroxine): NO

Effect on Dogs: Overdose can lead to symptoms like increased heart rate, nervousness, and excessive panting. Long-term effects can include heart problems.

11. Anti-Anxiety Medications (e.g., Xanax, Valium): NO

Effect on Dogs: These medications can cause severe sedation, respiratory depression, and in some cases, paradoxical excitement or aggression.

12. Antidepressants (e.g., Prozac, Zoloft): NO

Effect on Dogs: These can cause serotonin syndrome, leading to symptoms like agitation, increased heart rate, elevated blood pressure, and seizures.

13. Sleep Aids (e.g., Ambien, Lunesta): NO

Effect on Dogs: These medications can cause extreme sedation, unsteady gait, and, in some cases, paradoxical excitement.

14. Cholesterol Medications (e.g., Lipitor, Crestor): NO

Effect on Dogs: These medications can cause gastrointestinal upset, liver enzyme changes, and muscle damage in dogs.

15. Blood Thinners (e.g., Warfarin): NO

Effect on Dogs: Warfarin can cause severe bleeding, leading to life-threatening conditions if ingested by dogs.

16. Benadryl (Diphenhydramine): YES

17. Loperamide (Imodium): Yes/No

Effect on Dogs: Yes only if prescribed by your veterinarians in controlled doses for diarrhea. It can cause severe central nervous system depression in certain breeds, leading to lethargy and vomiting.

18. Antacids (e.g., Tums, Pepto-Bismol): Yes/No

Effect on Dogs: While some antacids are relatively safe in small doses, they can still cause gastrointestinal upset and electrolyte imbalances. Pepto-Bismol contains salicylates, which can be harmful in large amounts. Only give under your veterinarians supervision.
