Question: Can Dogs Take Antihistamines?

Question: Can Dogs Take Antihistamines?

Antihistamines.

Antihistamines are usually safe but make some dogs drowsy and others hyperactive.

OTC antihistamine preparations may contain other ingredients such as decongestants that are not safe for dogs.

Read the label carefully to assure that the product only contains antihistamine.

Which antihistamines are safe for dogs?

Claritin (loratadine)

I use them liberally in my practice, but they don’t lack side effects. Other OTC antihistamines may also be effective for allergic reactions in pets, but Benadryl, Zyrtec and Claritin are most commonly recommended.

Can I give my dog antihistamine tablets?

The standard dosage for oral Benadryl is 1 mg per pound of body weight, given 2-3 times a day. Most drug store diphenhydramine tablets are 25 mg, which is the size used for a 25 pound dog. Always double check the dosage before giving an over the counter medication.

How much Zyrtec can I give my dog?

Dogs weighing less than 10 lbs can have half of a 10mg tablet once daily. Chlortrimeton is another excellent antihistamine for dogs, and is the drug of choice for kitty allergies as well. It is approximately half the cost of Zyrtec per pill, but requires dosing twice daily instead of once.
