Can Allergies Cause Dizziness?


Allergies can cause several unpleasant symptoms, but is dizziness one of them?

The short answer is yes! Allergies can cause dizziness, and in rare cases, allergies can cause vertigo, a more intense form of dizziness. But why do allergies cause dizziness? In this article, we’ll talk about what might bring about this symptom and ways you can manage your allergies. If you want to find the source of your allergies, get your at-home allergy test from Wyndly, or read on to learn more about the link between allergies and dizziness.

Possible Causes

Dizziness is often a result of the common symptoms that are brought on by allergies. These symptoms can cause issues with the inner ear, which affects our sense of balance. Let’s take a look at some of these possible causes.

Inner Ear Issues

Several allergy symptoms can cause inner ear issues. Specifically, allergies can cause issues with the eustachian tube, which connects your inner ear and your throat. This tube helps with your balance and keeps the pressure in your inner ear equalized.

You may have noticed that your allergies sometimes make your ears feel clogged. This clogged feeling is mucus and inflammation in your inner ear, which makes it difficult for your eustachian tube to operate normally. This irregular clogging in your inner ear can cause symptoms of dizziness.

Medication Side Effect

Over-the-counter allergy medications are a common solution for managing allergy symptoms, but some of them come with some undesirable side effects. Drowsiness is one of the most common, but dizziness can be a side effect too. Check the information on the back of your allergy medication to see if dizziness is a side effect. If it is, you may want to consider switching to a different option.


Congestion is one of the main allergy symptoms that can bring on dizziness. Congestion can cause your inner ear to swell and make it difficult for your eustachian tubes to perform their normal functions.

Postnasal Drip

Postnasal drip can cause mucus to build up in your eustachian tubes, which can throw off your balance regulation and cause dizziness. When you have allergies, it’s common for excess mucus production to happen. A runny nose will cause the mucus to come out of your nose, but post nasal drip causes excess mucus to run from your nasal passage to the back of your throat.


Excessive bouts of coughing can sometimes cause you to feel dizzy or lightheaded. When you’re congested or you have postnasal drip, you may cough more than usual, causing your symptoms of dizziness.

Anaphylactic Shock

In some cases, allergies can cause a severe allergic reaction known as anaphylaxis. Anaphylaxis can be a life-threatening reaction and requires emergency medical attention. Dizziness can be a symptom of anaphylaxis, along with hives, nausea, trouble breathing, and swelling of the throat, mouth, lips, and skin.

If you’re experiencing an anaphylactic reaction, contact emergency services immediately. Those who are prone to anaphylactic reactions may want to carry an EpiPen with them.

Treatment Options

If you’re experiencing dizziness or any other allergy symptoms, there are options to manage and even treat your symptoms.


Among the best medications for managing allergy symptoms, especially dizziness, are antihistamines. Antihistamines provide short-term relief from several allergy symptoms and are widely available.

Antihistamines can help relieve symptoms of congestion, postnasal drip, and coughing. They can also reduce inflammation in the ears and nasal passages, which can help restore inner ear equilibrium and relieve symptoms of dizziness.

In short, taking care of your dizziness symptoms will entail managing the underlying allergy symptoms that are causing them. In addition to antihistamines, you can try other over-the-counter (OTC) treatments like nasal sprays, decongestants, and neti pots. These treatments all specifically target nasal inflammation and congestion, so they may provide you with the relief you need.

If you’re experiencing symptoms of dizziness and allergy meds aren’t helping, you may want to make an appointment with a doctor to rule out any other causes of dizziness. They may also recommend prescription allergy meds if OTC options aren’t working for you.

Sublingual Immunotherapy

Managing your symptoms with medications can provide you with short-term relief, but it doesn’t treat your symptoms at their source. If you’re looking for allergy treatment that can provide you with long-term relief, you may want to consider sublingual immunotherapy.

Sublingual immunotherapy introduces small amounts of your allergen to your immune system in incrementally increasing doses over time. This retrains your immune system to ignore these substances instead of responding to allergy symptoms. Sublingual immunotherapy is a simple, pain-free form of immunotherapy that you can do in the comfort of your own home. Over time your symptoms will be reduced, providing long-term allergy relief.

Reduce Your Exposure

Another smart way to manage allergy symptoms is by limiting your exposure to your allergens. There are several ways to limit exposure.

  • Check pollen levels: For seasonal allergies, check the pollen count when you get up in the morning. There are various apps and websites that can tell you the pollen count in your area. On days when the level is high, try to stay indoors or be sure to wear a mask when you leave the house.
  • Clean your home: Keeping your home clean is a good way to reduce your exposure to allergens. Using a HEPA-filter vacuum can help you reduce pollen, dust mites, pet dander, cockroach debris, and several other allergens from floors and carpets. It’s a good idea to use a wet rag to dust other hard surfaces. Also, make sure to kill any mold in your home with a mold cleaner or vinegar solution.
  • Keep windows closed: Keep windows closed during allergy season and run the A/C instead. It’s also a good idea to get a HEPA filter for your air system, so you can reduce the level of pollutants and allergens that get into your home.
  • Take shoes off when you get home: When you get home, take your shoes off so you don’t track in allergens.
  • Brush pets outside and bathe them often: Those who have pet dander allergies and own pets should brush their pets and bathe them often to get rid of dander. Also, do your best to keep pets out of the bedroom so you’re minimizing the dander you breathe in while sleeping.

Monitoring Your Diet

Dizziness can sometimes be a symptom of celiac disease, which is an immune response to gluten. Your doctor may monitor your diet if allergies aren’t causing your symptoms of dizziness.

You should also check to see what foods have cross-reactivity with pollen allergens. Certain foods have similar proteins to tree, grass, and weed pollen. If you’re allergic to these types of pollen, you may get allergy symptoms from eating certain foods.
