Understanding Sublingual Immunotherapy (SLIT)
Sublingual immunotherapy (SLIT) is a treatment where small drops or tablets are placed under your tongue to help your body get used to the things that cause your allergies. Over time, it reduces your symptoms and helps you feel better without relying on medicines every day. You would visit a doctor for SLIT if your allergies are affecting your daily life and you want a long-term solution.
Common Symptoms / Concerns for Sublingual Immunotherapy (SLIT)
When to Seek Professional Care
Book an evaluation with a healthcare provider immediately if you experience or present with:
- Difficulty breathing or shortness of breath
- Swelling of the face, lips, tongue, or throat
- Severe skin rash, hives, or swelling that spreads quickly
- Feeling dizzy, faint, or suddenly very weak
- Chest pain or a very fast heartbeat after exposure to an allergen
- Vomiting or stomach cramps that come on suddenly after contact with an allergen
- Allergy symptoms that are getting much worse despite taking your usual medicines
What to Expect During Your Medical Consultation
At your appointment, the doctor will ask you about your symptoms, how long you have had them, and what seems to trigger them — such as dust, pollen, or certain foods. They may also check your skin and listen to your breathing to understand how your allergies are affecting you. In some cases, they will arrange a simple allergy skin test or a blood test to find out exactly what you are allergic to before starting your treatment.

Frequently Asked Questions
What is SLIT and how does it work?
SLIT stands for Sublingual Immunotherapy. It involves placing small drops or a tablet under your tongue that contain tiny amounts of the substance you are allergic to. Over time, this trains your immune system to stop overreacting to that substance. Think of it as teaching your body to tolerate what used to trigger your allergy symptoms.
How long does SLIT treatment take?
SLIT is a long-term treatment that usually takes between one and three years to complete. You will need to take it regularly — often daily — for it to work well. Consistency is very important, so it helps to build it into your daily routine. Your doctor will check your progress and let you know when you can stop.
Is SLIT safe for children?
Yes, SLIT is commonly used for children and is considered safe for most kids. Many parents prefer it because there are no needles involved and it can be done at home. Your child's doctor will choose the right dose based on their age and allergy test results. As with any treatment, let your doctor know if your child has any other health conditions.
How does SLIT compare to allergy injections?
Allergy injections — also called subcutaneous immunotherapy — are given by a nurse or doctor at a clinic, usually on a regular schedule. SLIT works in a similar way but uses drops or tablets that you take at home under your tongue, so there are no needles. This makes SLIT more convenient for many people, especially those who find it hard to visit a clinic frequently. Both treatments can be effective; your doctor will help you decide which is right for you.
What allergies can SLIT treat?
SLIT can help with several common allergies, including dust mites, pollen, pet dander, and mould — all of which are frequent triggers in West Africa. It is especially useful if your symptoms are triggered by things in your everyday environment that are hard to avoid. SLIT is not suitable for every type of allergy, so your doctor will first do tests to confirm what you are allergic to. Based on those results, they will decide whether SLIT is the right option for you.
