Cyproheptadine is an antihistamine that is commonly used in pets. It is used in the treatment of many symptoms including allergies, loss of appetite, and increased serotonin production associated with Cushing’s disease. It does not treat the underlying problems causing these symptoms.
Along with it’s antihistamine effects, Cyproheptadine also works as an anti-serotonin agent. Serotonin is a neurotransmitter in the brain, and when it is suppressed, it leads to an increase in appetite. This is especially useful in cats undergoing chemotherapy, as they tend to lose their appetite. Diseases such as Cushing’s lead to an increase in serotonin, so cyproheptadine may be used to reduce serotonin levels.
Antihistamines counteract histamine, which is a chemical released to cause inflammation and itchiness as part of an allergic reaction. Cyproheptadine works by blocking H-1 receptors, which occur on the small blood vessels and smooth muscles. When histamine attaches to these receptors, it causes these vessels to widen causing inflammation and itchiness and muscles around the airways to contract, which causes difficulty breathing.
Store in a tightly sealed container at room temperature.
Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
