Types of Medications for Cat Allergies
Antihistamines block histamine, which is a biochemical messenger that triggers the immune response we characterize as an allergic reaction.
Hate drowsiness and want to feel fresh? Choose new generation antihistamines.
Antihistamines were developed in the 1940s. Early antihistamines penetrated the blood-brain barrier to reach histamine receptors in the brain.
Older antihistamines are referred to as first-generation antihistamine drugs. The older that an antihistamine is, the greater the likelihood of drowsiness and other side effects. These antihistamines are still on the market today. Perhaps the best-known example is Benadryl or diphenhydramine.
In the 1980s, scientists developed the second generation of antihistamine drugs.
New antihistamines cross the blood-brain barrier to a lesser extent than do first-generation antihistamines. Consequently, they cause fewer side effects and are usually non-drowsy.
They’re usually longer-lasting, allowing you to dose once daily rather than once every few hours.
For most allergy sufferers, newly-developed antihistamines provide relief without side effects.
Types of First-Generation Antihistamine Medications for Cat Allergies:
- Chlorpheniramine (ChlorTrimeton)
- Diphenhydramine (Benadryl)
- Promethazine (Phenergan)
- Hydroxyzine (Vistaril)
Types of New-Generation Antihistamine Medications for Cat Allergies:
- Loratidine (Claritin)
- Cetirizine (Zyrtec)
- Levocetirizine (Xyzal)
- Fexofenadine (Aller-ease, Allegra)
- Nasal Steroid Sprays
Not to be confused with the anabolic steroids your jacked-up brother-in-law probably uses, corticosteroids target inflammation to minimize allergy symptoms.
Nasal steroid sprays fight the stuffiness, itching, and runniness that make you and your nose miserable. Sensitive individuals may find that nasal steroids make their nose feel even worse. Side effects are rare, but they include nosebleeds and, ironically, runniness.
Types of Nasal Steroid Medications for Cat Allergies:
- Budesonide (Rhinocort)
- Fluticasone (Flonase)
- Triamcinolone (Nasacort Allergy 24HR)
Decongestants shrink the blood vessels in your nose, promoting airflow and helping you breathe easier. This is great when you haven’t breathed through your nostrils all day, but it’s important to remember that with shrunken blood vessels comes increased blood pressure. If you already have high blood pressure, this could be a problem.
Decongestants pose a risk to those suffering from glaucoma, heart conditions, diabetes, and thyroid disease. In essence, decongestants can help you breathe, but they can also make other problems a lot worse.
Therefore, decongestants aren’t a good choice for most cat allergy sufferers.
Types of Decongestant Medications for Cat Allergies:
- Pseudoephedrine (Sudafed)
Watch out for medications that contain acetaminophen.
Acetaminophen, the active ingredient in Tylenol, is added to some allergy medications to relieve headaches or other allergy-related pain. But it might not be a great inclusion in your allergy meds. Some medications contain 650mg of acetaminophen in every dose. With a dosage frequency of every four hours, a day of allergy medications would come with nearly 4,000mg or a maximum dose of acetaminophen in one day.
If you’re just feeling a little bit scratchy in the throat, a maximum dose of painkillers isn’t necessary or beneficial. And remember—acetaminophen isn’t necessarily harmless.
The Best Medication for Cat Allergies: Our Top Picks Reviewed
Remember—Allergy Medications Are Just One Part of Your Cat Allergy Treatment Plan.
We mentioned at the beginning of the article that medications aren’t a complete solution. With a multifaceted approach, you can reduce your cat allergies to a manageable level. Here are a few steps to bring you closer to that goal.
Start With the Allergens on Your Cat
Remember that cat allergens are secreted in your cat’s skin, saliva, and urine. By removing those allergens from your cat’s body, you can cut back on the allergens in your environment. If possible, a non-allergic individual should handle these tasks.
Wash Your Cat, Potentially Using an Allergen-Blocking Shampoo.
While washing with an ordinary shampoo or dish soap will help, an allergen blocking shampoo may be even better. There’s some evidence that allergen-blocking shampoos can neutralize dander. Just don’t bathe your cat more than once or twice a week. Any more could dry out their skin.
While cat hair isn’t allergenic itself, it carries dander and saliva, both of which contain cat allergens. By brushing your cat and throwing away the hair, you’ll minimize the amount of hair and dander in your home.
Keep Your Cat’s Skin Healthy.
Unhealthy skin breaks and flakes and sprinkles through your house. By improving your cat’s skin and coat health, you can minimize the amount of allergenic dander in the area. Omega-3 fatty acid supplements and a stellar diet can keep your cat’s skin and coat supple and strong.
Reduce Allergens in the Environment.
At roughly 1/10th the size of a dust allergen, these microscopic particles become airborne and remain in the environment for up to 6 months after the cat is no longer in the area. Regular cleaning is a necessity for those with cat allergies. Here are a couple ways to make a big impact.

Use an Air Purifier.
Capture airborne allergens with an air purifier. Not all air purifiers are equal, but the best ones capture these microscopic particles and make a big difference for allergy sufferers.
A powerful Roomba vacuum removes cat hair and dander from carpet and upholstery. If you choose one with a HEPA filter and minimal exhaust, allergenic particles will remain trapped in the vacuum and won’t re-enter the environment.
