Seasonal allergy treatment in Seoul, planned around pollen season

What seasonal allergy treatment in Seoul involves

Seasonal allergies, also called hay fever or seasonal allergic rhinitis, happen when the immune system overreacts to airborne pollen. The result is sneezing, a runny or blocked nose, itchy and watery eyes, an itchy throat and sometimes a cough or tiredness. Symptoms come back at the same time each year, which is the main clue that pollen is involved.

In Korea there are usually two main seasons. Tree pollen peaks in spring, roughly from March to May, and weed pollen, including ragweed and Japanese hop, rises again from late August into October. Spring yellow dust and fine dust can make symptoms worse, though they act as irritants rather than true allergens.

At VEI Clinic, seasonal allergy treatment starts with a consultation in English with Dr. HyunSung Park, a board-certified internal medicine specialist. He confirms the diagnosis, checks for related problems such as asthma or sinusitis, and puts together a plan that fits your symptoms, work and travel.

Diagnosis and allergy testing

Most hay fever is diagnosed from the pattern of symptoms and an examination of the nose, eyes, throat and chest. A cold usually lasts a week to ten days and may come with aches or a low fever; allergies last for weeks, cause more itching, and rarely cause fever.

Allergy testing is available at the clinic and can identify which pollens or other allergens you react to. It is most useful when the cause is unclear, when symptoms are severe or last all year, or when you are considering long-term desensitization treatment. A positive test only matters if it fits your symptoms, so Dr. Park interprets results alongside your history rather than on their own.

Treatment options

Treatment is usually a combination of medicines and simple steps to reduce exposure. Starting regular treatment a week or two before your usual season often works better than waiting until symptoms are severe.

Steroid nasal sprays take several days of regular use to reach full effect, so give them time and use the correct technique, aiming slightly away from the middle of the nose. Side effects are usually minor, such as nasal dryness or occasional nosebleeds. If one medicine does not control your symptoms, the doctor can adjust the combination rather than simply adding more tablets.

• Steroid nasal sprays: the most effective single treatment for a blocked, runny nose when used every day
• Non-drowsy antihistamine tablets: helpful for sneezing and itching, taken as needed or daily in season
• Antihistamine or anti-allergy eye drops for itchy, watery eyes
• Saline nasal rinses to clear pollen and mucus
• Other medicines for selected cases, such as leukotriene blockers when asthma is also present
• Allergen immunotherapy: long-term desensitization over several years for persistent, severe allergy, discussed and referred where appropriate

Who should be careful, and when to seek urgent help

Some people need extra care in choosing allergy medicines. Tell the doctor if you are pregnant or breastfeeding, have glaucoma, an enlarged prostate, high blood pressure or heart disease, or take several other medicines. Decongestant nasal sprays sold over the counter should not be used for more than a few days, as they can cause rebound congestion.

Seasonal allergies are not usually dangerous, but some symptoms need urgent attention.

• Swelling of the lips, tongue or throat, difficulty swallowing or breathing: call 119
• Severe wheezing or breathlessness not relieved by your inhaler: call 119 or go to an emergency room
• Facial pain with fever and thick discharge lasting over 10 days, which may be sinusitis: see a doctor
• Symptoms on one side only, nosebleeds or loss of smell that persists: book an assessment

Living with hay fever in Seoul

Small daily habits reduce your pollen load. Check the pollen forecast, which Korea's weather service publishes during the season, and keep windows closed on high-count days, especially in the morning. Shower and change clothes after time outdoors, wear sunglasses to protect your eyes, and dry laundry indoors during peak weeks. A good indoor air purifier can help on days when pollen and fine dust combine.

If you travel often, plan ahead: pollen seasons differ between countries, and the doctor can give you a supply and written instructions. Consultations for allergic rhinitis are usually covered by National Health Insurance for enrolled patients; visitors pay directly, and we explain the cost of any testing before it is done.
