This blood test measures the amount of the medicine fluphenazine in your blood. Fluphenazine is an antipsychotic medicine used to treat schizophrenia and Tourette syndrome. Fluphenazine helps you think more clearly. It also improves social exchanges, paranoia, and disposition. It can also help reduce involuntary movement related to Huntington chorea. The medicine can take up to 6 weeks to work as it should.
Fluphenazine also has potentially severe side effects and should be taken with caution. Older adults who use this medicine for dementia are at a higher risk of dying. It is not safe to use this medicine if you are allergic to it. You should not take this medicine if you have brain problems, a low blood cell count, or liver disease, or if you are breastfeeding.
You may have this test if it's possible that you have overdosed on fluphenazine or if you have dangerous side effects of the medicine. These include:
Tightness in your chest
Swelling in your face, lips, tongue, or throat
Extreme dizziness or fainting
Inability to urinate
If you have any of these symptoms or believe you have overdosed on the medicine, call your healthcare provider or 911 right away.
Many things may affect your lab test results. These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your healthcare provider.
The normal range of fluphenazine in the blood if taken as prescribed is 0.3 to 3 nanograms per milliliter (ng/mL).
You can have side effects with any dose of fluphenazine.
The test requires a blood sample, which is drawn through a needle from a vein in your arm.
Taking a blood sample with a needle carries risks that include bleeding, infection, bruising, or feeling dizzy. When the needle pricks your arm, you may feel a slight stinging sensation or pain. Afterward, the site may be slightly sore.
No other factors are likely to affect your test results.
You don't need to prepare for this test.
