Benadryl in the injectable form has a rapid onset of action. When used as a night-time sleeping aid, the usual dosage of Benadryl is 50mg at bedtime.

Can A Dog Overdose On Benadryl What To Look For What To Do

It is possible for dogs to overdose on Benadryl, and if they do, the consequences can be severe.

If you think your dog may have overdosed on the drug, contact your vet immediately to seek further advice.

If you can get your dog to a professional quickly after a possible overdose, its likely they will be able to recover.

Cases have been reported of dogs surviving a dosage 16 times higher than recommended with immediate hospital treatment.

Common symptoms that your dog may have received too much of the drug are:

  • Extreme fatigue

A less common side effect of overdosing on this drug is also high blood pressure, which may lead to seizures and other more serious issues.

When To Avoid Giving Your Dog Benadryl

Benadryl may negatively interact with other medications. Do not use Benadryl with any central nervous system depressants, or on a pet with high blood pressure, seizures, bladder issues, lung disease, or glaucoma. If your dog is having difficulty breathing or swelling in the facial area, take them to the vet ASAP. It is always important to monitor how your dog reacts to medicine or supplements to make sure that your dog is reacting well to the ingredients. This is especially important if your dog has a known health history or if it is the first time you are giving this medication to your dog.

Keep in mind that even if a dose of Benadryl calms your cats itchiness, it might not be treating the underlying problem. For example, if your cat has fleas or a fungal infection like ringworm, Benadryl will only offer temporary benefits. If your cats itchiness doesnt go away, schedule a veterinary visit for your cat.

Is Benadryl the Best Option for Treating Allergic Reactions?

Dr. Dean Mitchell, Board Certiallergic-reactions-and-benadryl.jpgfied Allergist in NYC, discusses why Benadryl is not the best antihistamine for allergic reactions.

For so many years people have thought that they should take Benadryl for allergic reactions. Its common to get Benadryl in the ER when you are having an allergic reaction and when people go to the drugstore they think Benadryl is the best antihistamine to take to help alleviate their allergies.

Just because Benadryl is the oldest antihistamine doesnt make it the best one to use when you have an allergic reaction. In fact, I rarely recommend using Benadryl for allergic reactions.

Today, there are better choices when you have an allergic reaction such as Claritin, Allegra, Zyrtec, and Sublingual Allergy Drops.

Benadryl vs Claritin

This is a non-sedating antihistamine which means it doesnt cross the blood-brain barrier so it doesnt make you tired. It also works quickly. In fact, today they have a Claritin ready-tab which you just put on your tongue and it works instantly. You can carry around these tabs in your wallet if you are prone to getting allergic reactions you cant predict.

Acrivastine capsules that you buy from pharmacies and supermarkets can be taken by adults under the age of 65, and children aged 12 years and over.

Acrivastine isn’t recommended for people over 65 years old because very little research on the medicine has been done in this age group.

Talk to your pharmacist or doctor if you’re over 65 and want to take acrivastine.

Acrivastine isn’t suitable for some people. Tell your doctor or pharmacist if you:

  • have had an allergic reaction to acrivastine or any other medicines in the past
  • have an intolerance to or cannot absorb some sugars, such as lactose or sorbitol
  • have kidney disease
  • have epilepsy or another health problem that puts you at risk of seizures
  • have a rare illness called porphyria
  • are booked to have an allergy test – taking acrivastine may affect the results, so you might need to stop taking it a few days before the test

Your vet may recommend Benadryl for dogs who have chronic allergic reactions to their environment.

Can I Give My Dog Benadryl Is Benadryl Safe For Dogs

Vets recommend Benadryl for dogs on a fairly regular basis, so the very broad answer to this question is, yes in SOME situations, Benadryl is safe to give to dogs.

There are, though, a lot of things you need to check carefully before you go ahead and administer this drug to your pet.

The most important thing to look for is that the particular Benadryl product you have only contains Diphenhydramine.

Cetirizine is an active ingredient in some Benadryl products that can be used for dogs in specific circumstances, but it wont treat the issues present if your vet has recommended Benadryl.

So steer clear of any products also containing Cetirizine, theres no need to expose your dog to unnecessary drugs that wont help them!

Acetaminophen and Pseudoephedrine are also found in some Benadryl products, and while these are a great addition for humans, they are not safe for dogs. If given to dogs, these drugs are considered to be toxins.

The most common problems caused by these two additional drugs are liver damage, and increased heart rate and blood pressure. So just be very careful to look at the ingredients in the product you are hoping to buy.

Even if youre happy that you have the right product to give to your pet, you simply must still speak to your vet before ever administering it.
