When it helps
When sublingual immunotherapy is the right step.
-
Moderate-to-severe hay fever
Symptoms limiting sleep, school, work or exam performance despite antihistamines and nasal steroids.
-
House-dust-mite allergy with year-round symptoms
Perennial rhinitis, poor sleep, worsening asthma.
-
Allergic asthma driven by grass, birch or mite
Confirmed sensitisation as a real driver of asthma control.
-
Teenagers heading into GCSEs or A-levels
Start SLIT 4 months before pollen season for the first summer of benefit.
-
Adults who have plateaued on standard treatment
Combination antihistamines and nasal steroids no longer enough.
-
Not for peanut or tree nut allergy
That is oral immunotherapy - a different pathway (Palforzia and specialist OIT).
-
Not for children under 5
Licensing and evidence do not support it below school age.
-
Red flag: severe uncontrolled asthma
SLIT is not started in severely uncontrolled asthma - that needs stabilising first.
Options
The right immunotherapy depends on the allergen and the age.
-
Grass pollen SLIT (Grazax)
Licensed for grass pollen hay fever from age 5 upwards.
-
House-dust-mite SLIT (Acarizax)
Licensed for adults with HDM-driven rhinitis and asthma.
-
Birch pollen SLIT (Itulazax)
For early-spring tree-pollen hay fever.
-
Ragweed SLIT tablet
Rarely needed in the UK; useful for travellers.
-
SLIT drops (unlicensed named-patient)
For allergens without a licensed tablet - cat, dog, mould in selected cases.
-
Subcutaneous immunotherapy (SCIT)
Weekly then monthly injections - used when SLIT is not suitable.
-
Venom immunotherapy
For bee or wasp anaphylaxis - a separate specialist pathway.
-
Combined SLIT + biologic
Selected asthma patients on omalizumab or dupilumab.
Our vetted UK network
A small panel of specialists, we picked them.

Safety and recovery
What to expect - honestly.
-
First dose in clinic
The first dose of a SLIT tablet is given under supervision to check tolerance.
-
Local mouth and throat itching
Common in the first weeks - usually settles.
-
Systemic reactions are rare
Anaphylaxis on SLIT is uncommon compared with SCIT.
-
Asthma control comes first
Uncontrolled asthma must be treated before starting SLIT.
-
Missed doses matter
More than a week off usually means restarting under supervision.
-
Pregnancy
SLIT is not started in pregnancy, but can be continued if already tolerated.
-
Dental work and mouth ulcers
Pause the tablet for a few days around procedures or open ulcers.
-
Adrenaline pen on hand
Some patients are asked to carry adrenaline during the induction period.
-
Red flag: airway swelling, breathlessness or collapse
Adrenaline first, 999 second. Every family with a diagnosed allergy needs to be clear on this.

Frequently asked
Everything we get asked about sublingual immunotherapy.
-
When is SLIT actually worth doing?
When hay fever or house-dust-mite allergy is genuinely limiting sleep, school, work or asthma control despite antihistamines and nasal steroids, and you are willing to take a daily tablet for 3 years. It is not for mild symptoms.
-
What does SLIT involve?
A licensed tablet placed under the tongue once a day for 3 years. The first dose is given under supervision in clinic; the rest is at home. Symptoms usually improve by the first pollen season and effects last for years after the course ends.
-
How much does SLIT cost privately in the UK?
Roughly £900–£1,400 per year for grass pollen, £1,100–£1,600 for house-dust-mite and £1,200–£1,800 for birch - a full 3-year course typically runs £2,700–£5,400 including consultations.
-
Is SLIT available on the NHS?
Selectively, through specialist allergy centres for severe hay fever or HDM asthma that has failed standard treatment. Access is limited and waits are long.
-
When should we start SLIT for hay fever?
Ideally 4 months before pollen season - so January or February for grass pollen. That gives the first full summer of benefit.
-
How long does the benefit last after the course ends?
Most studies show meaningful symptom improvement for at least 2 to 7 years after finishing a full 3-year course. Some patients need a second course later.
