Meds forming part of a category known as antihistamines help manage a variety of allergies. Many of these antihistamines work as short-action meds.

In this milieu, what are the safest antihistamines for dogs? It is a wise thing to have additional information on which drug is safe.

Drugs that are grouped as antihistamines help in managing (and treating) allergic conditions such as runny nose, cold, flu, rhinitis (allergic), nasal blockages, skin problems like reddening / discoloration of skin, itchiness and inflammation / swelling. Almost all antihistamines are taken for a shorter span of term; long term intake of such meds can cause other complications.

For dogs, according to the American Kennel Association, diphenhydramine (Benadryl) is considered a safe med.

What is diphenhydramine?

This property helps while you are traveling; it can make avid episodes of motion sickness and may calm your anxious canine friend. However, if your pet is pregnant or is already taking a few others similar meds, your vet may tell you to avoid using this antihistamine.

You need to know that an overdose of diphenhydramine can be unsafe to your dog. Excessive dosages may trigger epileptic fits, seizures or convulsions. Your dog may tend to get very sleepy or drowsy. It is a good practice to administer doses of this antihistamine as per the instructions of your treating vet. Reputed veterinary sources suggest that a dose of 3 milligrams (mg) per kilogram (kg) of your pet’s body-weight is considered a safe dosage form.

Your vet may also consider a few other options to treat allergic conditions in your dog. These are drugs such as cetirizine (safe dose is 1 mg per kg of pet’s weight), fexofenadine (safe dosage hovers between 3 to 4 mg per kg of pet’s body weight) and trimeprazine (~ 1 mg per kg of your canine’s weight).

In some cases, vets may also prescribe a few other forms of antihistamines.

A few side effects that you need to be aware of


Some antihistamine meds may have decongestants as part of their composition.

It is quite likely thing for dogs of select breeds – upon administering decongestants (and antihistamines) to develop severe allergic reactions. In all such instances, seek quick clinical help from a qualified vet.

Orally-disintegrating pills of antihistamine drugs are not considered safe for canines; this is because of the presence of a sweetener known as xylitol. This substance can develop toxicity among a few pets. In general, the pill / tablet versions of antihistamines are safe for dogs. When you give tablets to them, you have flexibility to alter doses i.e., after seeing how your pet responds to first few dosages. Lastly, never administer antihistamines to your dog without consulting your vet; always take the guidance of your vet prior to starting medication plans.
