What is Benadryl and What Does It Treat?

Benadryl, also known by its generic name diphenhydramine, is an over-the-counter antihistamine commonly used to alleviate symptoms of allergies in both humans and dogs.

It works by blocking the H-1 receptors on the blood vessels and smooth muscles, reducing the effects of histamine in the body.

In dogs, Benadryl is often used to treat symptoms of allergies, such as itching, hives, swelling, and sneezing.

It can also help to alleviate motion sickness during car rides and reduce anxiety in certain situations.

Safe Dosage of Benadryl for Dogs

The general rule of thumb for administering Benadryl to dogs is 1 mg per pound of body weight, given 2-3 times a day.

However, this dosage can vary depending on the dog’s health status and age, so it’s important to consult with a veterinarian before giving your dog Benadryl.

Also, it’s essential to note that only formulations of Benadryl that contain diphenhydramine as the sole active ingredient should be given to dogs.

Other formulations may contain ingredients that are harmful to dogs.

How to Administer Benadryl to Your Dog

Benadryl can be administered to dogs in tablet, liquid, or topical form.

If you’re using tablets, they can be hidden in a treat or piece of food to make it more palatable for your dog.

Liquid formulations can be measured out and given directly into your dog’s mouth with a dropper or mixed into their food.

Topical forms can be applied directly to the skin, but make sure your dog doesn’t lick the area immediately afterward.

Regardless of the form you use, make sure to observe your dog for any adverse reactions after administering Benadryl.

Potential Side Effects of Benadryl in Dogs

Drowsiness

The most common side effect of Benadryl is drowsiness.

This is because diphenhydramine, the active ingredient in Benadryl, is a sedative.

Dogs may appear lethargic or sleepy after taking this medication.

Dry Mouth

Benadryl can cause dry mouth in dogs.

You may notice your dog drinking more water than usual after taking this medication.

Urinary Retention

Benadryl can cause difficulty urinating in some dogs.

If your dog is straining to urinate or not urinating as much as usual, you should contact your vet.

Appetite Changes

Some dogs may experience changes in appetite when taking Benadryl.

This can include both increased or decreased appetite.

Gastrointestinal Upset

Benadryl can cause gastrointestinal upset in some dogs.

This can manifest as vomiting or diarrhea.

Rapid Breathing

In rare cases, Benadryl can cause rapid breathing in dogs.

If you notice your dog panting excessively or having difficulty breathing, contact your vet immediately.

Hyperexcitability

While drowsiness is more common, some dogs may have the opposite reaction and become hyperactive or agitated after taking Benadryl.

Always monitor your dog closely after administering Benadryl, and contact your vet if you notice any adverse reactions or if your dog’s condition does not improve.

Remember, while Benadryl is generally safe for dogs, it should always be administered under the guidance of a vet.

When to Contact Your Vet about Benadryl Use

While Benadryl is generally safe for dogs, it’s always a good idea to consult with your vet before giving your dog any new medication, including over-the-counter drugs.

You should also contact your vet if your dog’s symptoms do not improve after administering Benadryl, or if they experience any adverse reactions, such as vomiting, diarrhea, loss of appetite, or lethargy.

Furthermore, dogs with certain medical conditions, like glaucoma, high blood pressure, cardiovascular disease, or prostate enlargement, should not be given Benadryl without consulting a vet.
