10 Human Medicines that can harm your pet

  1. NSAIDS (non steroidal anti-inflammatory drugs) such as ibuprofen and naproxen. Even one or two of these pain medications can cause serious gastrointestinal problems including ulcerations and vomiting and diarrhea.

  2. Acetaminophen (Tylenol): In cats this can cause severe damage to the red blood cells and in dogs it can cause liver damage and with higher doses can also cause damage to the red blood cells.

  3. Antidepressants (Effexor, Cymblla, Prosac) These can cause neurological problems or increase in blood pressure. Cats often like the taste of Effexor.

  4. ADD and ADHD Medications (Concerta, Adderal, Ritalin). These drugs are stimulants and can cause tremors, seizures, increased temperature, or heart problems.

  5. Benzodiazepines and other sleep aids. In people these drugs are designed to reduce anxiety, but in our pets these drugs can actually have the opposite effect. They can cause incoordination. Some of these medications can cause liver failure in cats.

  6. Birth Control. The small container is sometimes fun to eat for the dog. The estrogen can cause bone marrow suppression (a very serious condition resulting in lack of red blood cells or white blood cells).

  7. Ace inhibitors (Zestril, Altace) Can cause dizziness and low blood pressure but usually doesn’t cause a big problem unless there is concurrent heart disease or kidney disease in the pet’s history.

  8. Beta-blockers (Tenormin, Toprol, Coreg) Can cause drop in blood pressure and drop in heart rate.

  9. Thyroid hormones. Human dosages are much smaller than our pet’s dosages so usually not a problem unless large doses are ingested. In large doses can cause tremors, panting, and nervousness.

  10. Cholesterol lowering agents (Lipitor, Zocor, Crestor) These can cause mild vomiting and diarrhea, but are meant for long term use, so other than the mild GI signs, serious side effects ar only found with long term use
