Dosage ALBEY VENIN OF GUEPE (Vespula) 120 μg Powder and solvent for solution for injection Box of 1 Vial of powder + vial of diluent of 1.8 ml

- Reconstitution and dilutions:
The extract is reconstituted by adding 1.2 ml of solvent to the contents of a powder vial.
The concentration thus obtained is 100 μg / ml. Additional vials of 1.8 ml of solvent may be provided as needed separately depending on the dilutions used.
To obtain a 10-fold lower concentration (10 μg / ml), inject 0.2 ml of reconstituted extract into a 1.8 ml vial of solvent. Repeat the procedure starting from the vial thus obtained (10 μg / ml) to obtain a concentration still 10 times lower (1 μg / ml) and so on.
- Use for the diagnostic test:
. Intradermally the test will be performed by injecting 0.05 ml of a solution of venom diluted to 0.001 μg / ml. In the case of a negative response, repeat the injection using a concentration 10 times higher and this until a positive skin reaction is obtained, without exceeding a maximum concentration of 1 μg / ml.
. For the Prick test, the usual concentration is 100 μg / ml.
- Use for desensitization treatment:
Strict subcutaneous route.
The protective maintenance dose is 100 μg of venom extract. It can be increased to 200 μg for patients inadequately protected by 100 μg.
The protocol used to achieve the maintenance dose of 100 μg should be adapted by a physician experienced in allergology, depending on the clinical condition and tolerance of the patient.
The arrival times at the maintenance dose depend on the method used:
. in a few hours (Ultrarush) or a few days (Rush): in a specialized environment only,
. in a few weeks: conventional method.
This maintenance dose is injected every 4 to 6 weeks, desensitization can be continued for 3 to 5 years, or longer in some cases.
- The recommended treatment regimens are identical in adults and children.
