How long a desensitisation protocol takes depends on the patient. In the same way that both the composition and dosage of the allergen solution is tailored to the individual, the duration of both the initial and the maintenance phase are determined by the individual's sensitivity and response.
On average, for perennial allergies:
Route of administration | Duration of the initial phase | Duration of the maintenance phase |
Subcutaneous injection | 12 to 14 weeks |
3 to 5 years
|
Sublingual administration | 11 days |
On average, for seasonal allergies:
Route of administration | Duration of the initial phase | Duration of the maintenance phase |
Subcutaneous injection | 12 to 14 weeks |
3 to 5 successive seasons |
Sublingual administration | 11 days for pre-seasonal treatment |
