Tegretol Blood Test Results Fully Explained

Tegretol is the brand name for Carbamazepine. It is a medication that is used for a number of conditions, including Bipolar disorder, nerve pain, and people who suffer from certain types of seizures. The Tegretol blood test is used to measure the amount of medication that is in the blood to determine if it is maintaining a therapeutic level of the individual.

When Tegretol is not at therapeutic levels, it may either not have the intended effect or cause unintended and possible uncomfortable side effects.

The blood test may also be used to determine what dosing may be appropriate for someone who is a good candidate for taking this medication. Then, based on the results that are received from the test, medication levels may be adjusted upward or downward so that a therapeutic effect can be established.

Once the medication reaches the individualized therapeutic range, Tegretol blood testing continues as a way to monitor the condition being treated. This test will often be ordered if a person’s health changes for some reason after starting this medication as well.

When to Ask About the Tegretol Blood Test

The most common reason to discuss the Tegretol blood test with a medical provider is because of the presence of uncomfortable side effective. Tegretol can cause side effects at any dosage level, but the chances of experiencing a side effect increases as the dosage increases.

These side effects may include dizziness, a lack of coordination, feelings of sleepiness, vision that becomes blurred or doubled, and involuntary movement of the eyes. More serious side effects may include a rash that is red and itchy, nausea, constipation, diarrhea, headaches, and prolonged confusion.

Anyone who has taken Tegretol and experiences a fever, chills, a sore throat, ulcers in the mouth or throat, or a rapid heartbeat that is accompanied by a difficulty in focusing should seek immediate medical attention. Easy bruising, severe tingling in the fingers and toes, swelling in the ankles, or the symptoms of jaundice also require immediate medical attention.

Tegretol may also cause lower sodium levels in the blood than normal, a decrease in white blood cells, or an increase in a specific type of white blood cell called eosinophils.

What Do My Test Results Mean?

For most individuals, the therapeutic range of Tegretol, when it is taken alone without any other medication, is between 4-12 mcg/mL. Any medication levels that are above 15 mcg/mL are considered to be toxic and need to be addressed immediately. Medication levels below 4 mcg/mL indicate that the medication has yet to take its full effect on the body and dosage levels may need to be increased.

Therapeutic ranges can vary from laboratory to laboratory. Some individuals may also be more tolerable of Tegretol than others and require a higher dose to achieve a therapeutic level.
