Can I give my dog loratadine and Benadryl?

Benadryl (diphenhydramine) is the most popular antihistamine for humans and can be effective for dogs as well. Just be aware that Benadryl has sedative properties, so your dog could get very drowsy. Other safe antihistamines for dogs include Claritin (loratadine) and Zyrtec (cetirizine).

The general rule is that canines shouldn’t take human medications. For instance, giving your pooch paracetamol can cause liver failure.

In healthy, adult dogs, certain antihistamine types can be administered without risk, and they can be an effective component of a treatment strategy for canine allergies.

However, dogs don’t respond to all kinds of antihistamines. Some will work, while others don’t seem to do anything. You may need to experiment with several different antihistamine types before you find one that works for your dog because this variable reaction appears to depend on the individual dog. Additionally, antihistamines simply can’t provide a long-term solution for your dog’s allergies on their own.

Antihistamines are typically taken by humans during the hayfever season to treat runny noses and itchy eyes. Additionally, they can be used to alleviate the signs of mild allergies or even wasp or bee stings. But in what situations can you give dogs antihistamines?.

Antihistamines. Common antihistamines include diphenhydramine (Benadryl®), cetirizine (Zyrtec®), and loratadine (Claritin®), which relieve allergy symptoms or prevent allergic reactions. Antihistamines are typically safe, but some dogs may become drowsy or hyperactive when taking them. OTC antihistamine preparations might also include decongestants, which are dangerous for dogs. To ensure that the product only contains antihistamine, carefully read the label. Verify with your dog’s medical team that the antihistamine you have is appropriate before using it.

Hydrogen peroxide. If your dog consumes something he shouldn’t have, hydrogen peroxide can be administered orally to cause vomiting in addition to being applied topically to clean out a superficial flesh wound (i e. , your medications, rodenticides, toxic plants). However, vomiting might do more harm than good, so speak with your veterinarian or an emergency veterinary facility PRIOR to giving your dog an oral dose of hydrogen peroxide to learn how much to give.

Mineral oil. This relatively benign liquid has a variety of uses. Before giving your dog a bath, you can put a few drops in his eyes to prevent soap stings.

Loperamide (Imodium®). When dosed at 1 mg per 20 pounds of body weight, this medication should be safe for your dog and a good last-resort treatment for diarrhea. Only give one dose. If the diarrhea does not resolve, contact your veterinarian. Targeted treatment of the issue will be possible with accurate diagnosis of the cause of the diarrhea.

Steroid sprays, gels, and creams. OTC steroid preparations are typically very safe and have a lower percentage of active ingredients than prescription steroids. The benefit is that they lessen itching from bug bites and hot spots. Steroids have the drawback of delaying healing, especially if the wound is infected. Have your dog’s wound examined by your veterinarian if it doesn’t look better after a few applications.


If your dog gets stung by a bee or wasp, the most crucial thing to do is to carefully remove the sting and wash the area with water. You can also use ice to lessen the pain and itching in your dog and to reduce the swelling.
