Just like the average human dogs also suffer from allergies and allergic reactions. Allergies can include food allergies, environmental allergies, and flea allergies. Regarding environmental allergies, if something in the air is impacting you, it’s likely also affecting your dog too.
Have dog owners have heard of Benadryl or even taken it themselves? Most likely. It is a popular seasonal medication that helps alleviate seasonal allergies.
Diving into Benadryl science 101, Benadryl is an antihistamine that blocks H1 receptors in smooth muscle and your blood vessels. These H1 receptors, histamine receptors, play a lead role in the allergic response. Benadryl not only blocks this receptor, but also reducblog-tabletates symptoms of these allergic reactions. Benadryl has also been used to provide mild sedation as well as being used to treat motion sickness for dogs.
What would your veterinarian say? Many veterinarians consider Benadryl to have a large safety margin, but there are still potentials for adverse effects and reactions associated with the drug that dog owners should be aware of.
The active ingredient in Benadryl is diphenhydramine HCl. Diphenhydramine has been categorized as a first-generation antihistamine - it can enter and cross the blood-brain barrier to address the allergic response. The blood-brain barrier protects the brain from dangerous or harmful foreign substances, like bacteria or foreign viruses. However, this blood-brain barrier does allow some substances, like diphenhydramine, to pass on through.
Because Diphenhydramine is able to cross the blood-brain barrier, this means that it is typically very effective in treating the allergic response. Diphenhydramine’s ability to cross the blood-brain barrier does, unfortunately, lead to increased risks for potential adverse reactions.
As most dog owners know, because of their own use of Benadryl, the drug is most commonly used to alleviate allergies.
Allergies have also been known to range from causing only quick bouts of itching to becoming a chronic, recurring condition throughout a dog’s life, which may lead to other infections and complications.
But - what some individuals may not realize is that Benadryl can be used for several other uses.
Starting with the basics here - when we think about allergies, we typically think about a runny nose, constant sneezing, and itchy eyes.
Well, dogs have different symptoms when experience allergies. In most cases, dogs show allergic reactions on their skin’s surface. It is possible that dogs will show signs of allergies that are similar to those you experience yourself, you’ll want to make sure that your pup doesn’t have a more serious issue at hand.
If your dog is having nasal discharge, coughing, and inflamed eyes, this can be a sign of multiple conditions in dogs, especially respiratory infections. So, it’s important not to automatically assume that your pup’s symptoms are from allergies.
Bottom line - your dog can suffer from allergies & your vet may recommend Benadryl to help alleviate your dog’s symptoms.
The most appealing part of Apoquel for dogs is how quickly it begins to work.
Unfortunately, we aren’t exactly able to communicate with our dogs in a clear way, despite how badly we wish we could. Our dogs can’t let us know when something in the air is bugging them, or if their food has ingredients they don’t like, or if any of this is making them feel funny. We can’t describe to them how badly insect bites feel and ask them to please avoid those fun, innocent-looking bugs are in the grass.
For this reason, knowing that Benadryl is safe to give to dogs, makes many dog owners feel somewhat at ease if their fun-loving pup is prone to being in grassy, itchy situations.
