6. Further information

Soluprick® is a solution for skin prick testing.
Soluprick® Positive and Negative Control are for
diagnostic use only. They are used as a reference with
other skin prick tests to determine which substances
cause your allergic reaction.
The Histamine Dihydrochloride in the Soluprick® Positive
Control will produce a hard raised weal, which may be
surrounded by a red area and this is called a positive
response. This response is compared with the
responses from substances that you might be allergic to.
Soluprick® Negative Control will usually not cause any
reaction, and is used to ensure that positive responses
are not caused by the prick of the lancet.

Do not use Soluprick® Positive and Negative control
• If you have ever experienced a bad reaction when
using this product or any other product containing
phenol or any other ingredient contained in the
solution (see section 6).
• If you have skin problems (atopic dermatitis) in the
area in which the skin prick test is to be applied.
Please inform your doctor if any of these statements
apply to you.
Take special care with Soluprick® Positive and
Negative control
Some conditions can affect the results of the skin prick
test, therefore please tell your doctor or health
professional before the skin prick test is carried out if:
• Your general health condition is seriously affected
by any disease;
• You suffer from active eczema or other skin
diseases in the area of the skin used for testing;
• You have had a lymph node in the armpit removed.
In extremely rare cases an anaphylactic reaction (a
severe reaction throughout the body that is recognized
by weals, itching, shortness of breath and fainting)
may occur after skin prick testing with substances that
you are allergic to. Therefore your doctor or health
professional should have an appropriate emergency kit
available before conducting the skin prick test, to be
able to take adequate emergency measures which may
include injection of adrenaline.
Beta-blocking medication (used by example for high
blood pressure and several heart diseases) may
influence the efficacy of adrenaline, so please tell your
doctor if you are taking beta-blocking medication.
Using other medicines
Please tell your doctor or health professional if you are
taking or have recently taken any other medicines
including those obtained without a prescription.
Some medicines can affect the results of the skin prick
test, therefore: Please tell your doctor or health
professional before the skin prick test is carried out if
you are taking any of the following medicines
• Short-acting antihistamines (usually used to treat
hayfever or skin hives), such as fexofenadine,
ebastine, promethazine within the last two to three
• Long-acting antihistamines (usually used to treat
hayfever or skin hives), such as cetirizine,
clemastine, hydroxyzine, promethazine, loratadine
within the last week;
• Antidepressants (of the type called `tricyclic
antidepressant`), such as amitriptyline,
clomipramine, imipramine, maprotiline, nortriptyline,
dosulepin and doxepin, within the last week;
• Corticosteroids (sometimes called steroids), such as
prednisolone and prednisone, which may be taken

to treat arthritis, inflammation of blood vessels
(called vasculitis), asthma and other diseases
• Corticosteroid creams and ointments (which are
used to treat eczema and other types of skin
inflammation) such as hydrocortisone, triamcinolone
acetonide, fluocortolone 21-pivalate, betamethasone
17-valerate, betamethasone dipropionate and
fluocinolone acetonide that you have applied to your
skin within the last two to three weeks
Pregnancy and breast-feeding

Skin prick testing can be performed if you are breast
Driving and using machines
Soluprick® Positive and Negative controls have no known
negative effect on the ability to drive and use machines.

Prick testing may be performed in children over the age
of one if the child is able to tolerate the procedure, but
in general should not be performed before the age of 4.
Your doctor or health professional will carry out the
skin prick test for you. The procedure is as follows:
• The skin prick test is usually carried out on the
inner side of the forearm. Alternatively the test can
be done on your back.
• Your skin must be dry and clean and may be
disinfected with alcohol by the doctor or
healthcare professional.
• The test solutions, Soluprick® Positive control and
Soluprick® Negative control are applied in droplets on
the skin at an appropriate distance from each other.
• The top layer of the skin is pierced by the doctor
or nurse with a lancet through the droplets.
• The reaction is read after 15 minutes. A positive
reaction is a pale small raised swelling or weal
with a red edge.

Like all medicines, Soluprick® can cause side effects,
although not everybody gets them.
Soluprick® Positive Control will cause the expected
local effects associated with histamine. The Positive
control will produce a hard raised weal, which may be
surrounded by a red area and local itching.
In some cases you may experience slight pain at the
skin prick test control site.
