Tinnitus is ringing, hissing, buzzing, or another sound in your ear that doesn’t have an external source.

About 10 percent of U.S. adults have experienced tinnitus lasting at least 5 minutes in the past year.

Many factors can contribute to the development of tinnitus, including:

Although tinnitus isn’t life threatening, it can significantly reduce your quality of life.

Allergies can cause a blockage in the tube that connects your ear to your throat and contribute to the development of tinnitus. Let’s look deeper at the connection between environmental allergies and tinnitus.

Allergies occur when your immune system overreacts to a usually harmless foreign substance. You can develop an allergy to many types of substances. A few common triggers are:

When your body encounters these substances, it produces an antibody called immunoglobin E to neutralize the perceived threat. When triggered, these antibodies cause the release of chemicals and symptoms like:

Your eustachian tubes connect the part of your ear behind your eardrum to your throat. Dysfunction of your eustachian tube can lead to symptoms like:

Current research suggests that environmental allergies can cause eustachian tube dysfunction by causing inflammation and functional obstruction.

Some studies suggest that 48.5 to 68 percent of people with chronic rhinosinusitis have eustachian tube dysfunction. Chronic rhinosinusitis is chronic inflammation in your sinuses that lasts for at least 3 months.

Some medications used to treat allergies may contribute to the development of tinnitus.

In a 2017 study, researchers described the first case study of tinnitus as a side effect of sublingual immunotherapy for house dust mite allergy. Sublingual immunotherapy works by administering a small amount of the substance that triggers the immune reaction under your tongue as drops so your body can build immunity.

Some people take nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin to help relieve allergy discomfort. Aspirin and other NSAIDs can cause tinnitus as a possible side effect, especially in large doses.

Increased inflammation or swelling from environmental allergies can affect your ears unevenly, possibly leading to a blockage and tinnitus in one ear. It’s generally recommended to visit a doctor if you experience persistent tinnitus in one ear to rule out a serious condition.

Allergies may contribute to eustachian tube dysfunction and make your hearing muffled. Your hearing should return to its usual function when you’re no longer exposed to the substance causing your allergies.

Chronic allergies may cause inflammation that damages the hair-like structures inside your inner ear that convert sounds to neurological signals. This type of hearing loss is called sensorineural hearing loss and is permanent.

No, traditional food allergies cannot cause tinnitus.

Vertigo is an uncommon but potential allergy symptom. It’s most common among people with allergic rhinitis. Some over-the-counter (OTC) allergy medications like bilastine and fexofenadine can cause dizziness.

Some medications used to treat allergies can cause tinnitus. For example, NSAIDs like aspirin can potentially cause tinnitus as a side effect, especially when taken in excessively high doses.

Allergies can raise your risk of developing other conditions linked to tinnitus.

Allergic rhinitis can raise your risk of developing middle ear infections. Middle ear infections can cause symptoms such as tinnitus, pain inside your ear, and hearing loss.

Allergic rhinitis can sometimes develop into a sinus infection due to obstruction in mucus drainage. Sinus infections, and nasal congestion in general, can cause abnormal pressure in your ears that affects your hearing or causes tinnitus.

Eustachian tube dysfunction is a blockage of your eustachian tubes and can lead to tinnitus. These tubes can get blocked for several reasons, such as allergies, colds, or changing altitudes.

Medications can help reduce tinnitus symptoms caused by allergies.

Antihistamines may help dry out your sinuses and enhance function of your ear passageways. Some types of antihistamines that have been used to treat tinnitus in people with allergies include:

OTC decongestants and nasal corticosteroids may also help reduce tinnitus by relieving congestion and inflammation in your sinuses.

If medications like NSAIDs contribute to your tinnitus, ceasing them may help alleviate symptoms.

If possible, avoiding the source of your allergy can help reduce your symptoms. If you suspect an allergy but aren’t sure what you’re allergic to, you may benefit from visiting a specialist called an allergist.

The National Health Service recommends seeing a doctor about tinnitus if:

Some of the reasons the American College of Allergy, Asthma, & Immunology recommends seeing an allergist include:

Allergies may contribute to the development of tinnitus by causing dysfunction of the tubes that connect your ears to your throat. Some medications used to treat allergy symptoms, such as NSAIDs, may also contribute to symptoms.

Tinnitus can develop for many reasons, and it can be hard to isolate the underlying cause. If your tinnitus or allergy symptoms are causing you significant discomfort, it’s a good idea to visit or contact a doctor for proper diagnosis and treatment.
