What medicine works best for cat allergies
The best way to hold your symptoms under control is often to avoid the things you’re allergic to, although this is not always practical.
For example, you may be capable to help manage:
- food allergies by being careful about what you eat
- mould allergies by keeping your home dry and well-ventilated, and dealing with any damp and condensation
- hay fever by staying indoors and avoiding grassy areas when the pollen count is high
- animal allergies by keeping pets exterior as much as possible and washing them regularly
- dust mite allergies by using allergy-proof duvets and pillows, and fitting wooden floors rather than carpets
Eight cat allergens own been recognized by the World Health Organization/International Union of Immunological Societies (WHO/IUIS) Allergen Nomenclature Sub‐Committee.
Fel d 1 is the most prominent cat allergen, accounting for 96% of human cat allergies. The remaining cat allergens are Fel d 2-8, with Fel d 4, an urinary protein, occurring the most in humans among the other seven allergens. Every cats produce Fel d 1 including hypoallergenic cats. The main way these allergens are spread is through a cat’s saliva or dander, which gets stuck on clothing. A study found that 63% of people allergic to cats own antibodies against Fel d 4.
Fel d 1
Fel d 1 is the most dominant cat allergen. It is part of the secretoglobulin family, which are proteins found only in mammals.
Fel d 1 is primarily secreted through the sebaceous glands and can be found on the skin and fur of a cat. It is less commonly secreted through the salivary gland, lacrimal glands, skin and anal glands.
Fel d 4 and Fel d 7
Fel d 4 and Fel d 7 are cat lipocalins. Fel d 4 and Fel d 7 are one of the most common cat allergens after Fel d 1. Fel d 4 is primarily found in cats’ saliva and is associated with atopic dermatitis in children with cat allergies.

Allergies to cats are one of the most common allergies among individuals.
Among the eight known cat allergens, the most prominent allergen is secretoglobinFel d 1, and it is produced in the anal glands, salivary glands, and, mainly, in sebaceous glands of cats, and is ubiquitous in the United States, even in households without cats. Allergic symptoms associated with cats include coughing, wheezing, chest tightening, itching, nasal congestion, rash, watering eyes, sneezing, chapped lips, and similar symptoms.
In worst case scenarios, allergies to cats can develop into more life-threatening conditions such as rhinitis and mild to severe forms of asthma. Despite these symptoms, there are numerous types of solutions to mitigate the allergic effects of cats, including medications, vaccines, and home remedies. Hypoallergenic cats are another solution for individuals who desire to pets without the allergic consequences.
Furthermore, prospective pet owners can reduce allergic reactions by selecting cats of a specific gender or color, which are associated with a lower production of allergens.
Immunotherapy may be an option for a little number of people with certain severe and persistent allergies who are unable to control their symptoms using the measures above.
The treatment involves being given occasional little doses of the allergen, either as an injection, or as drops or tablets under the tongue, over the course of several years.
The injection can only be performed in a specialist clinic under the supervision of a doctor, as there’s a little risk of a severe reaction.
The drops or tablets can generally be taken at home.
The purpose of treatment is to help your body get used to the allergen so it does not react to it so severely.
This will not necessarily cure your allergy, but it’ll make it milder and mean you can take less medicine.
Treating severe allergic reactions (anaphylaxis)
Some people with severe allergies may experience life-threatening reactions, known as anaphylaxis or anaphylactic shock.
If you’re at risk of this, you’ll be given special injectors containing a medicine called adrenaline to use in an emergency.
If you develop symptoms of anaphylaxis, such as difficulty breathing, you should inject yourself in the outer thigh before seeking emergency medical assist.

Medicines for mild allergies are available from pharmacies without a prescription.
But always enquire a pharmacist or GP for advice before starting any new medicine, as they’re not suitable for everyone.
Antihistamines are the main medicines for allergies.
They can be used:
- as and when you notice the symptoms of an allergic reaction
- to prevent allergic reactions – for example, you may take them in the morning if you own hay fever and you know the pollen count is high that day
Antihistamines can be taken as tablets, capsules, creams, liquids, eye drops or nasal sprays, depending on which part of your body is affected by your allergy.
Lotions and creams
Red and itchy skin caused by an allergic reaction can sometimes be treated with over-the-counter creams and lotions, such as:
- moisturising creams (emollients) to hold the skin moist and protect it from allergens
- calamine lotion to reduce itchiness
- steroids to reduce inflammation
Decongestants can be used as a short-term treatment for a blocked nose caused by an allergic reaction.
They can be taken as tablets, capsules, nasal sprays or liquids.
Do not use them for more than a week at a time, as using them for endless periods can make your symptoms worse.
Steroid medicines can assist reduce inflammation caused by an allergic reaction.
