What Causes Cat Allergies?

Cat allergies are caused by a reaction to allergens found in a cat’s saliva, urine, and dander. These allergens can become airborne and enter your respiratory system, causing a range of symptoms, including sneezing, runny nose, itchy eyes, and congestion.

Types of Cat Allergy Medicine

There are several types of cat allergy medicine available over-the-counter and by prescription. The most common types of cat allergy medicine are antihistamines, decongestants, and corticosteroids.


Antihistamines are the most common type of cat allergy medicine. They work by blocking the histamine produced by the body in response to allergens. Histamine is responsible for many allergy symptoms, including itching, sneezing, and congestion. Over-the-counter antihistamines such as loratadine and cetirizine can be effective for mild cat allergies. However, if your symptoms are severe, your doctor may prescribe a stronger antihistamine such as fexofenadine.


Decongestants can help relieve congestion caused by cat allergies. They work by narrowing the blood vessels in the nasal passages, reducing swelling and congestion. Over-the-counter decongestants such as phenylephrine and pseudoephedrine can be effective for short-term relief of congestion. However, they can cause side effects such as increased heart rate and elevated blood pressure, so they should be used with caution.


Corticosteroids are anti-inflammatory drugs that can help relieve inflammation caused by cat allergies. They work by suppressing the immune system’s response to allergens. Corticosteroids are available in pill form, as a nasal spray, or as an inhaler. They can be effective for treating severe cat allergies, but they can cause side effects such as weight gain, mood changes, and increased risk of infection.


Immunotherapy, also known as allergy shots, is a long-term treatment for cat allergies. It works by gradually exposing your immune system to increasing amounts of cat allergens, desensitizing your body to the allergens over time. Immunotherapy is typically reserved for people with severe cat allergies that do not respond to other treatments.

Natural Remedies

In addition to conventional cat allergy medicine, several natural remedies may help relieve cat allergy symptoms. These include saline nasal rinses, steam inhalation, and herbal supplements such as butterbur and stinging nettle. While there is limited scientific evidence to support the effectiveness of these remedies, many people find them helpful in relieving their allergy symptoms.

The best cat allergy medicine for you will depend on the severity of your symptoms and your personal preferences. If you have mild cat allergies, over-the-counter antihistamines may be sufficient to relieve your symptoms. However, if your allergies are more severe, you may need a prescription medication such as a corticosteroid or immunotherapy. It’s important to discuss your options with your doctor to find the best cat allergy medicine for you. They can help you weigh the benefits and risks of each treatment and make an informed decision.

Safety Considerations

When choosing a cat allergy medicine, it’s important to consider potential side effects and interactions with other medications. Some cat allergy medicines, such as decongestants and corticosteroids, can cause significant side effects, so it’s important to use them only as directed and under the supervision of a healthcare professional. Additionally, some cat allergy medicines can interact with other medications you may be taking, so be sure to inform your doctor of all medications you’re currently using.


Cat allergies can be a nuisance, but with the right cat allergy medicine, you can manage your symptoms and continue to enjoy the company of your feline friends. Whether you opt for an over-the-counter antihistamine or a prescription corticosteroid, there are plenty of options available to help relieve your allergy symptoms. By working with your doctor to find the best cat allergy medicine for you, you can take control of your allergies and start breathing easier.
