Never give Ibuprofen (Neurofen, Advil) to dogs or cats! These may be one of the most common human over-the-counter medications and while they have a large safety margin for humans, pets have different sensitivities to them and they can be fatal.

While well-intended owners may administer these medications to their pets at home if they are in pain or injured or playful pets may knock over a bottle or packet of pills and ingest an unknown quantity, the consequences can be disastrous.
