1. Zyrtec vs Zyrtec D – What to Avoid?

The D is an abbreviation that stands for pseudoephedrine that deals with congestion in humans. When applied to dogs, pseudoephedrine has lethal consequences as it overstimulates the heart and the central envious system of your canine causing heart failure, dog seizures, or even potential death for your canine. Before applying Zyrtec on your canine, it is advisable you get the right prescription from your vet to ensure the maximum safety of your furry friend.

2. Lactating and Pregnant Dogs

In human females, Zyrtec is not administered to breastfeeding and pregnant mothers. This applies to your canine too. It has been discovered that antihistamine medicines have an adverse side effect on the growing fetus. It is not safe to administer the drug to your lactating pooch as the ingredients of this drug can be passed from mother to puppy through the milk, but having consulted your vet before giving the medicine to your pet is an ideal option.

3. Not For Dogs That Have Kidney and Liver Problems

Never use Zyrtec for canines that suffer liver and kidney health problems. This will just make the condition worse than before. Zyrtec causes urine retention in canines. On a healthy dog, this is not a big issue, but for suffering dogs, this might mean death. This is because suffering dogs are unable to clear the drug from their system efficiently. It can be advised that you get another medication before reaching Zyrtec for your pets.

Small breeds of dogs such as Maltese will take 0.5 mg of Zyrtec. Bigger dogs such as bulldog will take 10 mg of Zyrtec tablet. To make this simple let’s place it in the following way, canine with less than 10 pounds should be given 0.5 mg of Zyrtec once in a day. Those weighing above 10 pounds should be given one full tablet of 10mg Zyrtec once a day.

Zyrtec Side Effects

Although Zyrtec is known to be safe for canines, as for any medicine, it is advisable to be vigilant and watch out side effects. If you are familiar with the potential side effects of other alterative medications, then you are aware that Zyrtec does not have present many adverse side effects.

The research has it that only 30% of antihistamine works appropriately and may have an adverse reaction. This is because antihistamine does not cure the condition but acts as a reliever to the condition. While Zyrtec will treat the symptoms, it will not be able to cure the entire underlying problem, which is more severe than seasonal allergy. The common side effects of Zyrtec include sleepiness, vomiting, constipation, urine retention, excessive salivation, and impulsive response.

Smaller dogs are more susceptible to drowsiness side effects compared to larger ones, but this becomes less severe as the dog adjusts to the medication. Anytime you give new medication to your furry friend, keep a close eye on them. They will not be able to communicate their woes to you as the person could do, so you remain to be the one to monitor them to ensure their wellness.

However, with older and dogs that suffer live and kidney problems, the effects are scarier as it can lead to additional issues. While your canine no longer portrays any sign of allergy, it might be as a result of Zyrtec exacerbating other issues that might be worse than itchy skin. The best thing is to be having a regular appointment with your vet to ensure that he checks on your four-legged babies regularly to identify if they are ready for Zyrtec medication.
