How should severe pollen allergy sufferers prevent and treat it?

Pollen allergies, also known as hay fever or allergic rhinitis, occurs when an individual's immune system reacts to airborne pollen particles from trees, grasses, and weeds. While pollen is commonly viewed as a harmless substance, it can be deadly for individuals who suffer from severe pollen allergies. In this article, we will discuss how severe pollen allergy sufferers can prevent and treat this condition.


Prevention of pollen allergy involves reducing the risk of exposure to pollen allergens. While it is impossible to avoid pollen altogether, certain measures can help minimize exposure and reduce the severity of allergy symptoms.

1. Stay Indoors When Pollen Counts are High

The first and perhaps most critical measure to prevent pollen allergies is to avoid exposure to the particular allergen that triggers the allergy. When pollen counts are high, it is best to stay indoors, close windows, and use air conditioning instead of fans.

2. Use High-Efficiency Particulate Air Filters

Using high-efficiency particulate air (HEPA) filters can help remove pollen particles from indoor air. These filters trap pollen particles before they can cause allergy symptoms.

3. Keep the Indoor Environment Clean

Keeping the indoor environment clean involves removing pollen particles that may have entered the home. This involves vacuuming carpets, floors, and upholstery regularly. Regular cleaning of bedding, drapes, and other textiles can also help reduce pollen particles.

4. Reduce Outdoor Activities

On windy days when pollen counts are high, it is best to reduce outdoor activities. Individuals with pollen allergies should limit their outdoor activities to early morning or late afternoon, as these are times of the day with lower pollen counts.

5. Wash Your Clothes and Hair Regularly

Pollen particles can easily attach to clothes and hair and transfer to the indoor environment. It is, therefore, essential to wash clothes and hair frequently. Showering before bedtime can also help remove pollen particles from the hair and skin.


While prevention is crucial in managing pollen allergies, it is not always possible to prevent exposure to pollen allergens. When exposed to pollen allergens, individuals with severe pollen allergies may experience a range of symptoms, including sneezing, runny nose, congestion, and itching of the eyes, nose, throat, and skin. The following are steps and remedies that can be taken to treat severe pollen allergy symptoms:

1. Antihistamines

Antihistamines are the first-line medication used to treat the symptoms of pollen allergies. Antihistamines work by blocking the effects of histamine, a chemical that the body releases when exposed to pollen allergens. Over-the-counter antihistamines such as cetirizine (Zyrtec), loratadine (Claritin), and fexofenadine (Allegra) can help relieve the symptoms of pollen allergies. It is recommended to take the medication as prescribed by the doctor and to avoid overdose.

2. Decongestants

Decongestants can help relieve nasal congestion, a common symptom of pollen allergies. These medications work by narrowing the blood vessels in the nasal passages, reducing the swelling and clearing the congestion. Over-the-counter decongestants such as pseudoephedrine (Sudafed) and phenylephrine (Sudafed PE) can be used to treat nasal congestion. However, decongestants use should be limited to a few days as they may cause rebound congestion.

3. Nasal Sprays

Nasal sprays such as corticosteroids and antihistamines can help relieve nasal congestion, itching, and runny nose. These medications work by reducing inflammation in the nasal passages and preventing the release of histamine. Over-the-counter nasal sprays such as fluticasone (Flonase) and triamcinolone (Nasacort) can be used to treat pollen allergy symptoms. However, nasal spray use should be limited to a few days to prevent addiction.

4. Eye Drops

Eye drops can help relieve eye irritation and itching caused by pollen allergy. Over-the-counter eye drops such as ketotifen (Zaditor) and naphazoline (Visine) can be used to relieve symptoms. However, prolonged use of eye drops can cause rebound effects.

5. Immunotherapy

Immunotherapy is a treatment that involves exposing the immune system to small doses of allergens gradually over time, eventually helping the body to build up immunity to allergens. Immunotherapy is usually administered through shots or oral tablets. Immunotherapy is suitable for individuals with severe allergies who do not respond well to other treatments.


Pollen allergies are a common problem for many people, and severe pollen allergy sufferers can experience significant discomfort and disruption in their daily activities. Prevention and treatment of pollen allergies involve reducing exposure to the allergen and treating allergy symptoms. While there is no cure for pollen allergies, the use of antihistamines, decongestants, nasal sprays, eye drops, and immunotherapy can help alleviate allergy symptoms. It is essential to consult a doctor before starting any treatment to ensure the use of appropriate medication for pollen allergies.
