Customer Question

I have a 10-pound dog who might have ingested most of my husband's namenda capsule, 28 milligrams, today or yesterday. Yesterday I noticed that she drank more water than usual. Any advice?

The acute oral toxicity of this drug in dogs is low. The LD50 - the dose at which 50% of dogs died was a high 23 mg/lb or ~230 mg for Bebe. It's more likely that you wouldn't see any adverse effects at even a full 28 mg but excitation, decreased awareness and motor activity are possible. High doses did affect dogs' kidneys but even 28 mg wouldn't be considered a high dose in the toxicity studies performed in dogs.
