The best antihistamine for itchy dogs and cats

Have you ever noticed your furry friend scratching incessantly or showing signs of an allergic reaction? Cetirizine, commonly known by brand names such as Zyrtec and Reactine, could be a solution for your pet’s discomfort. In this article, we’ll delve into what cetirizine is, how it’s administered, potential side effects, and some natural alternatives to consider.

What is Cetirizine?

Cetirizine is an antihistamine used to treat pruritus (itching) associated with atopic dermatitis, urticaria (hives), and insect-bite reactions in cats and dogs. It’s important to note that its use in cats and dogs is ‘off label’ or ‘extra label’, meaning it’s commonly prescribed for conditions not specified in the official labeling. As always, follow your veterinarian’s directions and cautions very carefully when administering off-label medications.

How is Cetirizine Administered?

Cetirizine is given orally, either in the form of a tablet or as an oral syrup. It can be given with or without food, but if your pet shows signs of sickness or vomits after receiving the medication, try giving it with a small amount of food. Typically, the medication takes effect quickly, within 1 to 2 hours, and improvement in your pet’s symptoms should follow.

Missed Doses

If you miss a dose of cetirizine and your pet is receiving it twice a day, give the next dose when it’s time to do so. For once-a-day dosing, give it when you remember and continue at the regular time. Never give your pet two doses at once or give extra doses.

Potential Side Effects

Cetirizine usually doesn’t cause any side effects. However, some dogs may experience vomiting and increased salivation. At high doses, sleepiness has been reported in small dogs and cats. Any severe or worsening side effects should be reported to your veterinarian. This medication typically stops working within 24 hours, but effects can last longer in pets with liver or kidney disease.

Risk Factors

• Do not use the combination product containing pseudoephedrine in dogs and cats.
• Cetirizine should not be used in pets with a hypersensitivity to it or hydroxyzine.
• Use cetirizine with caution in pets with seizure disorders, difficulties urinating, constipation, thyroid problems, prostatic enlargement, heart, kidney, or liver disease, or glaucoma.

Dosage

Standard dog and cat doses are 5mg/10lbs of body weight given once daily. Tablets are typically 10mg, so 1/2 tab for a 10lb dog or cat.

Comparisons and Natural Alternatives

Many dog parents find cetirizine to be the most effective antihistamine for allergy flare-ups, with far fewer side effects than Benadryl. It appears to be a safer over-the-counter antihistamine and is more effective when combined with Essential Fatty Acids (i.e., Krill).

For those looking for a natural option, consider a whole plant extract that combines all parts of the plant for maximum benefit. Many pet parents have found success with this natural alternative.

I wish I had some Cetirizine a few days ago, although I did find some Benadryl that helped. Cetirizine is safer and doesn’t make you drowsy.

Conclusion

Cetirizine can be a valuable tool in managing your pet’s allergies and discomfort. Always consult with your veterinarian before starting any new medication, and closely monitor your pet for any adverse reactions. With the right approach, you can help your furry friend enjoy a more comfortable and itch-free life.
