Hayfever Out of Control? Discover Relief with HayTox Treatment

Seasonal allergies like hayfever can make life miserable—constant sneezing, congestion, runny nose, and fatigue can interfere with work, sleep, and your enjoyment of daily life. If antihistamines or nasal sprays leave you feeling foggy, or simply aren’t enough, you’re not alone.

At Merrion Medical Aesthetics, Dr. Kate Healy offers an innovative solution: HayTox. This quick, needle-free treatment uses a neuromodulator spray to target overactive nasal glands and dramatically reduce symptoms—helping you breathe, move, and live more comfortably.

Common Areas Affected

Nasal Passages

The nasal passages are the primary site affected by hayfever. When allergens are inhaled, they trigger inflammation in the nasal lining, leading to congestion, sneezing, and a constant runny nose. This swelling can make it difficult to breathe comfortably and often disrupts sleep, daily focus, and overall comfort.

Sinuses

As nasal inflammation worsens, it often affects the nearby sinus cavities. Blocked sinuses can lead to pressure, facial discomfort, and even sinus headaches. For many people, this congestion feels like a constant heaviness behind the cheeks and eyes—one of the most frustrating parts of seasonal or year-round allergies.

Eyes

Itchy, red, and watery eyes are a classic symptom of hayfever. Allergens can irritate the delicate tissues around the eyes, causing swelling and discomfort. For some, these symptoms are so pronounced that they interfere with reading, screen use, or simply being outdoors, adding to the overall impact on quality of life.

Throat

Post-nasal drip—mucus that drains from the nose down the back of the throat—can cause persistent irritation. This often results in a dry, scratchy, or sore throat, especially in the mornings or after being outside. In some cases, it can also cause coughing or hoarseness, making allergies feel more like a lingering cold.

Frequently Asked Questions

What is HayTox and how does it work?

HayTox is a nasal spray application of botulinum toxin (commonly known as Botox). It works by blocking the nerve signals that stimulate mucus production, reducing symptoms like congestion, sneezing, and runny nose.

Is the treatment painful?

Not at all. HayTox is needle-free and uses an atomized nasal spray. Most patients report no discomfort during or after treatment.

How long do the results last?

Relief typically lasts between 3 and 6 months. Some patients with severe hayfever may require a second treatment about 4 weeks after the first for optimal results.

Are there any side effects?

Mild symptoms like temporary nasal irritation or a nosebleed may occur but are uncommon. Some patients feel minor hayfever-like symptoms for 5–10 minutes after the procedure.

Who should not get HayTox?

HayTox is not recommended for those who are pregnant, breastfeeding, or allergic to botulinum toxin. Patients with neurological disorders like Myasthenia Gravis or a current upper respiratory infection should also avoid treatment.

How do I prepare for my HayTox appointment?

We may recommend saline nasal rinses in the weeks prior to your appointment and continuing your current antihistamines until the treatment takes full effect. Dr. Kate will guide you through a personalized prep plan.
