Some medical conditions and medicines may put you at risk of harm or interfere with how well the VIT works. Sometimes VIT may not be recommended.
Speak to your doctor or allergy specialist if you have: –
- uncontrolled asthma – VIT can cause allergic reactions. It is very important that your asthma is well-controlled before starting treatment
- chronic heart disease – any allergic reaction, whether to a sting or to VIT may be more serious
- autoimmune diseases – very little is known about how this may affect treatment.
Always tell your allergy specialist about any medicines (including over the counter, herbal or supplements) you are taking before starting VIT.
