What is Benadryl?

Benadryl is an antihistamine that is primarily used to treat hey fever and allergies in humans. With cetirizine, pseudoephedrine, and acetaminophen being its prime ingredient, Benadryl is readily available at local pharmaceutical stores. The prime drug used in this medicine is diphenhydramine.

What is Benadryl used for treating?

As mentioned above, it is an anti-allergic medicine that is primarily used for curing hey fever in humans. It is also used for curing itchiness and swelling in pets, which is a resultant of pet allergies. This drug is also used for treating symptoms related to vomiting, stress, swelling, sleeplessness, motion sickness, hives, and hypertension in pets.

Is Benadryl Safe for Dogs?

While this drug works as an effective anti-allergic medicine for humans, if your chosen drug contains pseudoephedrine and acetaminophen then, it should not be administered to your beloved pet (as these two ingredients are harmful to your pets). These two active ingredients can prove toxic for pets if administered and may lead to increased blood pressure, increased heart rate, and damage to the liver.

Even cetirizine (an active ingredient of Benadryl) may not be useful for treating your beloved pet’s ailments and should, therefore, be avoided. If your vet recommends Benadryl to your ailing dog, choose the drug that contains diphenhydramine. Read the ingredient list carefully before administering Benadryl to your beloved pet. Always seek your vet’s permission before giving this medicine to your dog.

Can Benadryl be given to my Dog?

Yes, you can give the pet your Benadryl medicine, as there is no pet-friendly variety of this drug available in the market. While the (FDA) has yet to approve the administration of this anti-allergic medicine on dogs, vets usually prescribe Benadryl as it is effective in controlling allergic reactions in dogs. Besides, it does not cause any adverse side effects.

It is good to know that Benadryl, in its capsule form, is not recommended for pets. Tablets are ideally meant to release the medicine in a phase-wise manner. If your dog chews it, then he would end up consuming an excessive dose of Benadryl. If he swallows it then, the medicine may not be properly digested, resulting in it being ineffective for treating the ailment.

How does Benadryl work?

Benadryl reduces swelling and itchiness caused by allergic reactions. It reduces the actions of the histamine chemical present in our body. Histamine is responsible for providing relief to the human body from an allergic reaction. This chemical attaches itself to either the H1 or the H2 receptor.

When histamine attaches itself to the H2 receptor, it causes increased heart rate and excessive acid secretion in the abdominal region. When histamine attaches itself with the H1 receptors, it causes inflammation, itching, and may hamper normal breathing. Dogs, too, have H1 and H2 receptors, but their reaction quotient towards histamine is different from the reaction quotient present in humans.

This anti-allergic medicine is given to both dogs as well as humans to block the action of histamine and provide relief from its side effects. Please note that Benadryl is ideal for treating the reactionary H1 receptor side effects (such as swelling and itchiness), and it does not help to combat H2 receptor side effects (high acid production or increased heart rate).

Benadryl Dosage for Dogs

How much Benadryl is enough for your dog?

An ideal dose for a dog is 1 milligram of Benadryl per pound of your pet’s body weight. Only use Benadryl that contains diphenhydramine. Nonetheless, if your pet has been bitten by an insect that has led to an allergic reaction, you may increase the dose but only after consulting the doctor. In certain cases, you can even double the dose (2 milligrams per pound of your pet’s body weight).

How often is enough?

The ideal dosage is twice daily and, in extreme cases, thrice daily but no more. A minimum gap of 8 hours needs to be maintained between two doses. Always follow the dosage as prescribed by the vet. Avoid giving Benadryl to your pet way too often else; its effectiveness would reduce with time. In the case of prolonged administration of this medicine, take a periodical break or administer your dog with another anti-allergic medicine.

When shouldn’t you give your Dog Benadryl?

Some of the common ailments include heart diseases, lung diseases, enlarged prostate, glaucoma, allergy to diphenhydramine, and high blood pressure.

Some of the common ones include dryness in the mouth, insomnia, lower amounts of urine, lack of appetite, an upset stomach, and general illness. It is important to make a note of the fact that each dog has a different sensitivity level to Benadryl.

If you mistakenly administered an extra dose of Benadryl, seek a vet’s advice. You can detect whether your pet has been administered an overdose by noticing the following symptoms – muscle spasms, tiredness, irregular heartbeat, difficulty in breathing, high blood pressure, or increased body temperature. In case of a high overdose, your dog may suffer from a seizure, so take him to a vet immediately.
