Cats who are aggressive or anxious and ones who obsessively spray are also candidates for sedatives.If you think your kitty needs a sedative, it's imperative that you only sedate him using prescribed medication, and under your veterinarian's care.Antihistamines are a class of agents that block histamine release from histamine-1 receptors and are used to treat the symptoms of an allergic reaction, such as edema (swelling), itch, inflammation (redness), sneezing, or a runny nose or watery eyes.Antihistamines can be further divided into those unlikely to cause drowsiness (non-sedating antihistamines) or those likely to cause drowsiness (sedating antihistamines).Not many cats will sit still long enough for a mask to be placed over their mouths and noses, and then for the medication to take effect.Typically the cat is placed in an acrylic box into which a combination of oxygen and the gas is pumped.Some sedatives can cause psychological and physical dependence when taken regularly over a period of time, even at therapeutic doses.
Halothane, isoflurane and sevoflurane are medications in gas form used for sedating cats.
Because some can cause serious side effects or interact with other medications you are taking, be sure to let your doctor know all the medications you take.
Your doctor can guide you to the right antihistamine for you.
Although sedatives do not relieve pain in themselves, they can be a useful adjunct to analgesics in preparing patients for surgery, and are commonly given to patients before they are anaesthetized, or before other highly uncomfortable and invasive procedures like cardiac catheterization, colonoscopy or MRI.
They increase tractability and compliance of children or troublesome or demanding patients.
