Benadryl for Cats

Benadryl (antihistamine)

Human allergic reactions inflame the sinuses; in cats, they irritate the skin. Benadryl, or any regular-strength antihistamine whose sole active ingredient is diphenhydramine, often relieves pain in cats. Get Kitty to the center if she’s scratching obsessively to get rid of severe issues, and guarantee your veterinarian supporters off-label antihistamine use. The right dose of antihistamine can help stop that itching.

How It Works

Benadryl is the household-name-brand drug launched in 1946 and now readily available in generic form universally. In the United States, Benadryl and generics use the active ingredient diphenhydramine, generally in a hydrochloride base. The over-the-counter medication fights allergy symptoms, amongst them itching and inflammation. Diphenhydramine is an antihistamine, suggesting that it deals specifically with histamines– inflammatory biochemicals that cause skin inflammation, swelling, pain, increased heart rate and drop in high blood pressure drop when viewed by receptors in the body. Benadryl obstructs them from doing so, avoiding symptoms.

Which Form to Buy for Cats

Benadryl is available in 25 milligram and 50 milligram capsules, 12.5 milligram chewable tablets, 50 milligram tablets, an oral elixir and a syrup. For cats, among the oral kinds is suggested. It is easier to determine a precise dosage with liquid than with pills. It is also extremely tough to get cats to eat or swallow tablets.

Dosage, Side Effects and Effectiveness

According to the Cat Health Guide, you can provide your cat 2 milligrams per pound of body weight every 8 hours. For example, if your cat weighs 10 pounds, you would offer him no greater than 20 milligrams per dosage. It works best if provided to your cat prior to direct exposure to the reason for the itching, however if the cause is something in your cat’s environment, this is obviously not possible. Drowsiness is a side effect of taking Benadryl for cats simply as it is for humans. Another is a strong anti-nausea effect, which is not a bad thing. According to Mar Vista Vet, a California veterinary clinic, Benadryl is not as effective in animals as in human beings. It might work within an hour of giving it, or a few weeks might expire before relief is kept in mind. Until then, it’s liable to make your cat too sleepy to lick and scratch.


Do not offer your cat Benadryl if he takes any form of tranquilizer. Also, do not provide him simply any Benadryl-brand medicine and even any antihistamine. Make sure that the antihistamine you offer your kitty contains absolutely nothing however diphenhydramine as an active component. Benadryl products that treat other symptoms such as headaches consist of other active components also. Some such compounds, such as acetaminophen, can be deadly to family pets. Whether you use Benadryl or a generic, make sure it’s regular-strength, no-extras diphenhydramine.
