Motion sickness: The sedating action of Benadryl may also aid in the prevention of motion sickness during automobile or airline travels with your dog. Vaccine reactions: “Puppies receive immunizations early in life, and it is possible that they will have a reaction to these vaccines,” adds Price. According to Price, veterinarians frequently recommend giving your puppy Benadryl two to four hours before the immunization visit in order to calm responses like as puffiness or lethargy.

Dosing instructions for Benadryl

It is recommended by theMerck Veterinary Manual to administer 0.9-1.8 mg of Benadryl per pound of body weight (2-4 mg/kg of weight) to your dog. If you wish to experiment with over-the-counter Benadryl, the most effective version is generally a tablet, which has 25 mg of the medication per tablet, according to Dr. Justinine Lee, a board-certified veterinarian who specializes in toxicology and emergency care. This implies that, on average, a 25-pound dog would receive one pill, while a 50-pound dog would receive two pills.

According to Price, veterinarians can also prescribe a canine version of Benadryl called Vetadryl, which is an FDA-approved type of diphenhydramine that is safe to provide to dogs and cats with no side effects.

  • There is a 10 mg alternative, which may make dosage more convenient
  • The addition of dog-friendly flavorings may make it more enticing to your pooch.

Precautions when using Benadryl

Keep the following considerations in mind when using Benadryl:

  • According to Price, “Benadryl is available over-the-counter for pet parents to purchase, but this should only be done under the supervision of a veterinarian.” Your veterinarian can establish the most appropriate starting dose for your dog and evaluate whether Benadryl will have a negative impact with any other drugs he or she is already taking. Lee advises that if you’re buying Benadryl over-the-counter, “you should make sure it’s Benadryl that is solely diphenhydramine and has no additional substances put in,” she adds. Keep an eye out for substances like as acetaminophen or decongestants, which may not be suitable for canines. Always check the expiration date on the Benadryl before giving it to your dog, according to Price, because outdated medicine might be harmful to your dog.

Side effects of Benadryl in dogs

Some of the most frequently reported adverse effects of Benadryl are as follows:

  • Dry lips, rapid breathing, and inability to urinate are all symptoms of a hypothyroid condition.

“Even though Benadryl is a safe medication, overdose is a possibility,” adds Price. The following are some probable indicators of overdose:

  • Agitation, seizures, dilated pupils, rapid heartbeat, constipation
  • These are only a few of the symptoms.

In the event that you suspect an overdose, call your veterinarian immediately and bring in the packaging for any drugs that were delivered, advises Price. If you’ve given your dog Benadryl to treat an allergic reaction, keep an eye on him to see if his symptoms are becoming better or worse. “If your dog is having problems breathing or the swelling is growing worse, you should take him to the doctor or an emergency vet as soon as possible,” Lee advises.

Diphenhydramine, also known as Benadryl®, is one of the most widely prescribed over-the-counter drugs for both humans and animals. It is classified as an antihistamine and has been in use commercially since the mid-1940s, when it was discovered. Benadryl is one of 15 human over-the-counter medications that are considered safe for dogs. Diphenhydramine is a kind of antihistamine that works by inhibiting the function of histamine, specifically its effect on the H1 receptors on the surface of the skin.

Swelling and itching are reduced or prevented as a result of this treatment. Diphenhydramine has little to no influence on the rate of heartbeat or the production of stomach acid. Listed below are some further facts on histamine and antihistamines:

  • When the body responds to inflammation or an allergy, histamine is released into the bloodstream. This substance goes throughout the body in search of histamine receptors that are distinct to the individual (targets on cells). Histamine will produce swelling, itching, and other symptoms associated with an allergic response once it has attached itself to the receptors in the body. H1 and H2 histamine receptors are the two kinds of histamine receptors. H1 receptors have an effect on the smooth muscles of the blood vessels and tiny blood vessels. Small blood vessels dilate and fluid leaks out as a result of histamine attaching to the H1 receptors in the blood vessels. This leads in swelling of the tissues and itching of the skin. Aside from that, the smooth muscles lining the narrow airways tighten, resulting in discomfort and considerable trouble breathing. Heart rate and stomach acid release are both influenced by H2 receptors. Histamine attaching to H2 receptors causes the heart rate to increase as well as the production of stomach acid to increase, thereby raising the risk of getting ulcers. Antihistamines are medications that work by inhibiting the effects of histamine. There are a variety of medicines that have antihistamine properties, some of which are effective in the treatment of allergies and others which are useful in the prevention of excessive stomach acid. If the antihistamine binds to the H1 receptors or the H2 receptors, the actions of the antihistamine are different. There are just a few medications that have the ability to hit both types of receptors.

What Is Benadryl?

This medication has only been approved for use in humans. Many different conditions may be treated with diphenhydramine. It can be used to treat allergy symptoms as well as sleeplessness, nausea, tremors, and other symptoms associated with cold viruses, among other things.

  • Benadryl® (Parke-Davis), Genahist, Sominex, Unisom, and many generic medicines are examples of human formulations. Calmatrol (Goldman Pharmaceutical), Vetadryl (Pegasus), and a variety of generics are available for use in veterinary medicine.

Despite the fact that diphenhydramine is readily accessible over-the-counter, it should only be administered under the direction and supervision of a veterinarian. Despite the fact that the Food and Drug Administration (FDA) has not authorized this medication for use in animals, veterinarians can lawfully prescribe it as an extra-label medication. Benadryl is available in the following forms: liquid, tablet, and capsule.

  • 10 mg, 12.5 mg, 25 mg, 30 mg, and 50 mg tablets
  • 12.5 mg/5 ml suspension
  • 2 mg/ml, 10 mg/ml, and 50 mg/ml concentrations of injectable diphenhydramine

Uses of Diphenhydramine for Dogs

Diphenhydramine is generally used to treat chronic allergy symptoms such as itchy skin, acute allergic responses such as hives and skin swelling, vaccination or medication reactions, snake bites, insect stings, and other unidentified causes of itchy skin, and chronic allergic symptoms such as itchy skin. Other use for Benadryl in dogs include:

  • If a dog has had a history of vaccine responses, it is normal practice to provide Benadryl before a vaccination. It is also given to dogs who have had an unfavorable reaction to a blood transfusion. Because of its effects on the brain and neurological system, it is commonly used to treat motion sickness and vomiting (chemoreceptor trigger zone). But there are alternative medications for motion sickness that are more helpful, such as maropitant (Cerenia®), which is a kind of antihistamine. If your dog has mast cell tumors, you should give him diphenhydramine before surgery. If your dog has vestibular sickness, you should give him Benadryl. This is a disorder that interferes with the balance and equilibrium of the body.

Despite the fact that diphenhydramine is generally considered safe and effective in dogs, there are alternative treatments for persistent allergies that have been shown to be more helpful. Food allergies in dogs, as well as allergies caused by environmental exposures, are prevalent and can result in itching, hair loss, and skin infections in some cases. According to some research, antihistamines are only helpful in treating the symptoms of chronic allergies in around a quarter of the dogs that take them.

Atopic dermatitis and food allergies in dogs are two topics that might provide further knowledge about chronic allergic reactions in dogs.

How does Benadryl work?

A chemical release of histamine occurs in the body as a result of an allergic response. Histamine, once produced, attaches to receptors on certain cells, producing itching and inflammation in the affected area. H-1 receptors are the name given to these receptors. Benadryl (also known as Diphenhydramine) is an antihistamine that acts by inhibiting the H-1 receptors in the body and so lowering the effects of histamine on the body. It works by inhibiting the signals that are sent to the dog’s vomiting area in the brain when he or she is given Benadryl for motion sickness.
