Human medicines are dangerous for dogs and cats

In clinical routine Pet Care , we serve numerous animals intoxicated by human medications that were administered by his tutors without veterinary guidance. Often owners find that slightly decrease the drug’s dose will solve the problem of your dog or cat, however, many medications are toxic and can cause serious problems to the animals or get them to death.

We must be careful with this kind of self-medication, because it is very dangerous. Medicate animals requires professional knowledge and should only be done by a veterinarian, not the guardian or even the attendant feed homes or pet shop. Sometimes, small economies can endanger the life of your pet. In other cases, the poisoning occurs without the intention of the tutor: the drugs are exposed or easily accessible locations and the animal accidentally eat.

Vitamin D derivatives

Even small exposures to Vitamin D derivatives such as Calcipotriol (calcipotriene) and Calcitrol, can cause death threat because they make the calcium level increases in the blood of animals. Small signs of exposure, including vomiting, loss of appetite, increased frequency of urination and thirst (caused by kidney failure) may appear until more than 24 hours after ingestion.

Most of the active ingredients of drugs used in veterinary medicine is also found in human medicine. So often prescribed medications are found in both “human pharmacies” as in “Veterinary pharmacies”, but their use should be made exclusively by prescription from a veterinarian.
