Benadryl

GENERAL DESCRIPTION:

Benadryl® is an antihistamine that is commonly used in both people and 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.

Only give this drug under the recommendation of your veterinarian. Dosages vary and you should always consult your vet before giving this drug to your pet.

HOW IT WORKS:

Antihistamines counteract histamine, which is a chemical released to cause inflammation and itchiness as part of an allergic reaction. Diphenhydramine 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.

The anti-motion sickness property of Benadryl® works by blocking impulses to the vomiting center in the brain. This is only effective in dogs.

STORAGE INFORMATION:

Store in a tightly sealed container at room temperature.

MISSED DOSE?

Give the missed 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.
