1. What Alutard SQ Vespula spp. is and what it is used for

Alutard SQ Vespula spp. contains the allergen (the substance that causes the allergic reaction) from wasp venom. It is used as a preventive treatment for allergy to wasp stings.

This treatment is used in patients with a history of severe allergic reactions to wasp stings. The aim of the treatment is to address the underlying cause of the allergy. It works by gradually increasing immunological tolerance to wasp venom.

Children and adolescents

Children aged 5 years and older: Information on the effect of treatment in children is limited. Safety data have not shown a higher risk in children compared to adults. It is recommended that the doctor evaluate the risks and benefits for each child.

Use of Alutard SQ Vespula spp. with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

• you are taking any other medication for your allergy, such as antihistamines or corticosteroids, as these may increase your tolerance to this treatment. The doctor may need to adjust the dose
• you are taking medications containing large amounts of aluminum, such as certain antacids (used for heartburn). Since Alutard SQ Vespula spp. also contains aluminum, there may be a risk of aluminum accumulation in your body

3. How to use Alutard SQ Vespula spp.

Treatment with Alutard SQ Vespula spp. is administered via an injection. The injections are usually given in your arm, under the skin. Your doctor or nurse will always administer the injections.

You must remain at the clinic for at least 30 minutes after the injection so that any potential allergic reaction can be detected and treated.

On the day of the injection, you should avoid: strenuous physical exercise, hot baths, and alcohol.

The treatment consists of two phases: the initial phase and the maintenance phase.

Initial phase:

Treatment will begin according to the schedule established by your doctor. During the initial phase, injections are usually administered once a week. This phase typically lasts between 7 and 25 weeks.

The goal is to gradually increase the dose until reaching the maximum dose you can tolerate or the recommended maximum maintenance dose. If there is a reaction at the injection site lasting more than 6 hours after the injection, your doctor may adjust the dose based on the extent of your skin reaction. Your doctor may prescribe antihistamines prior to the injection.

Maintenance phase:

Once the maintenance dose has been reached, the time between injections will gradually increase, until injections are given every 6–8 weeks for a period of 3–5 years.

Treatment with more than one allergen at the same time:

If you are treated with more than one allergen simultaneously, there must be at least a 30-minute interval between injections.

If you use more Alutard SQ Vespula spp. than you should

A doctor will administer your treatment with Alutard SQ Vespula spp. In the event of an overdose, you will be monitored and treated by a physician.

If you forget to use Alutard SQ Vespula spp.

Contact your doctor if you think a dose has been missed. If the interval between two injections has been too long, your doctor may reduce the dose to prevent you from experiencing an allergic reaction.

If you stop treatment with Alutard SQ Vespula spp.

To achieve the best outcome from your treatment, you will need to receive the injections for 3 to 5 years.

If you have any further questions about the use of this medicine, ask your doctor.
