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 wheal, 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.
- If you are allergic to any of the ingredients in Soluprick Positive and Negative Control apart from the active substance (listed in section 6).
Please inform your doctor if this statement applies to you.
Talk to your doctor before using Soluprick Positive and Negative Control.
- If you have skin problems in the area the skin-prick test is to be applied
- If you suffer from a disease which is affecting your general health
Tell your doctor or healthcare professional if you are taking, have recently taken or might take any other medicines including those obtained without a prescription.
Some medicines can affect the results of the skin prick test, therefore: Tell your doctor or healthcare professional before the skin prick test is carried out if you are taking any of the following medicines:
- Short-acting antihistamines within the last three days;
- Long-acting antihistamines within the last week;
- Steroids at doses higher than 10 mg prednisolone per day;
- Strong steroid preparations applied to your skin within the last three weeks
Tablet treatment with less than 10 mg prednisolone per day will not suppress the reaction to the skin prick test.
Other medicines may interfere with the result of the skin prick test. You should discuss with your doctor the risk of discontinuing treatment compared with the benefits of having a skin prick test.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using this medicine.
There are no adequate data from the use of Soluprick Positive and Negative Control in pregnant women. This product should not be used in pregnant women unless the benefits are considered by the treating physician to outweigh the risks.
Skin prick testing can be performed if you are breast feeding.
Soluprick Positive and Negative Controls have no influence 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 of 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 wheal with a red edge.
Skin prick test with Soluprick is given by a healthcare professional. In the event of an overdose, you will be monitored and treated by a healthcare professional.
Like all medicines, Soluprick can cause side effects, although not everybody gets them.
In some cases you may experience slight pain at the skin prick test site (frequency not known).
Soluprick Positive Control will cause the expected local effects associated with histamine. The Soluprick Positive Control will produce a hard raised wheal, which may be surrounded by a red area and local itching after the test.
