Customer Question

I am a university student researching animals in conflict zones. Can Diazepam (Other drug type? Injectable or tablet?), be used to calm aggression in wild boar, big cats or a range of the largest land mammals, without impairing awareness or ability to walk? Will they be easier controlled? How long does the drug need to take effect? How long does it last? Effects on the animal? How is it administered? Thanks.

Your questions touches on a new approach to wildlife management, so there is not a lot of information about it out there. However, I have done some initial research, and I would suggest starting with information links I have found below. You can then go on to extrapolating to the rest of your study.

After reading my response here, please rate it so that I can be credited for my research time. This is a very interesting subject, and I would be happy to discuss further questions at no additional charge once you have done the rating.

Good luck in your study endeavors, Patience P.


Veterinary behaviorists say that the use of Benzodiazapenes such as Diazepam (Valium) and Alprazolam (Xanax) can affect the central nervous system of nonhuman animals and actually anxiety, stress and fear. However, It has also been found that many calmative medications lose their effec iveness when the animal is over-stimulated, leading to unpredictable behavior. In addition, diazepam and other such medications may adversely affect the offspring of pregnant or nursing animals. Effects with the fast-acting drugs may begin to be seen in as little as 30 minutes and may last for as long as 24-48 hours. I suggest checking out the links below to get better figures on timing, dosages, and different animal effects.

Most veterinarians probably would recommend skipping oral medications and instead using injectables, because they have a more predictable response. Pole syringes are cheap, safe methods of delivery, but they are only useful when the animal is physically restrained or is in a trap. Blow pipes are even better to inject medications in wild animals. However, they only have a range of 10-15 meters, and experience is required for them to be used effectively. Dart guns and the like can introduce additional problems that probably would offset their usefulness for this application.
