Sublingual Immunotherapy (SLIT) in Singapore

A needle-free way to retrain your immune system. SLIT delivers a small, controlled dose of allergen under the tongue every day, building long-term tolerance to dust mites, cat dander, and dog dander โ€” the most common drivers of allergic rhinitis in Singapore. Personalised and supervised by Dr Pang at Mt Elizabeth.

Personalised Care for Lasting Relief from Allergies

Living with allergies to environmental triggers like dust mites, cat dander, or dog dander significantly affects quality of life. At CENTAS, we offer safe and effective sublingual immunotherapy (SLIT) tailored to manage these allergies long-term โ€” without the need for regular injections.

What is Sublingual Immunotherapy?

SLIT is a modern treatment designed to gradually reduce or eliminate the body's allergic response to specific environmental allergens. The therapy involves placing small, controlled amounts of the allergen under the tongue for 2 to 5 minutes โ€” typically once a day โ€” so the immune system learns to tolerate rather than overreact to it.

SLIT is currently used to manage:

This personalised approach has transformed life for many patients with stubborn allergic rhinitis, persistent nasal congestion, allergic conjunctivitis, and allergic asthma.

How Sublingual Immunotherapy Works

The principle is simple: train the immune system to recognise the allergen as safe. A small daily dose under the tongue progressively shifts the immune response away from IgE-mediated inflammation toward immune tolerance. Over months, allergic reactions become less severe and less frequent. Unlike antihistamines and nasal sprays โ€” which suppress symptoms only โ€” SLIT addresses the underlying allergic disease.

Benefits of SLIT

Who Can Benefit from SLIT?

Dr Pang conducts a thorough evaluation โ€” medical history, allergy testing results, severity, and overall health โ€” to confirm SLIT is the right fit for you.

Our Expertise

The SLIT Process

  1. Comprehensive consultation โ€” review of medical history, allergy symptoms, and goals to confirm SLIT is right for you
  2. Allergy testing โ€” skin prick test or specific IgE blood test to identify the exact allergen(s) and your baseline sensitivity
  3. First dose under supervision โ€” taken in the clinic so any early reaction is observed and managed
  4. Maintenance phase โ€” daily dose at home, with periodic follow-up to track progress and adjust as needed

Modern SLIT regimens often skip the prolonged dose-escalation phase altogether โ€” patients start at the maintenance dose on day one, which improves compliance and reaches symptom benefit sooner.

Why this matters in Singapore. Year-round dust mite exposure is essentially universal in our tropical climate, making allergen avoidance almost impossible. SLIT is one of the few treatments that meaningfully changes the disease itself โ€” and at CENTAS, it's often integrated with sinus and snoring care for patients whose allergy drives multiple problems at once.

Safety and Risks

SLIT is safe under specialist supervision. Common, mild side effects in the first weeks include:

These usually settle on their own as your body adapts. The first dose is always taken in the clinic so any reaction can be observed. Severe systemic reactions are rare. Patients with poorly controlled asthma or recent oral wounds may need to delay treatment โ€” Dr Pang will discuss any precautions during your consultation.

Frequently Asked Questions

Is sublingual immunotherapy safe for children?
Yes. SLIT is safe for children when supervised by an ENT or allergy specialist and is an effective option for dust mite, cat, and dog allergies in younger patients. The needle-free format is especially well tolerated in children.
How long does SLIT take?
Most patients notice symptom improvement within 6 to 12 months. A full course is typically 3 years for durable, long-term tolerance, though some patients see meaningful benefit and reduced medication use within months.
Will SLIT cure my allergy?
SLIT does not "cure" allergy outright, but it significantly reduces sensitivity to the targeted allergen. Many patients experience long-lasting symptom relief and reduced reliance on antihistamines and nasal sprays, with benefits often persisting after treatment ends.
Are there any risks or side effects?
Mild side effects are common in the first few weeks โ€” itching or tingling under the tongue, mild throat irritation, or transient stomach discomfort. These usually settle on their own. Severe reactions are rare; the first dose is taken under supervision to minimise risk.
Can I eat or drink normally after SLIT?
Yes. Avoid food and drink for 5 minutes after each dose to maximise absorption under the tongue, then resume normal eating. The only restriction is the specific allergen being treated if it overlaps with a food (e.g. some pollen-food syndromes).
How is SLIT different from allergy shots (SCIT)?
SCIT is given as injections in clinic. SLIT is taken daily as a sublingual tablet or drops at home, after a first dose under supervision. Both work by inducing immune tolerance. SLIT is needle-free and more convenient; SCIT has the longest track record and remains preferred for some allergens.
