Bipolar disorder is also called manic-depressive illness. In this condition, one feels a full range of emotion swings and tends to experience very high-level emotions ranging from mania or hypomania, at times extreme. Most medicines taken in treating bipolar conditions are usually prescribed to be a drug combination alongside the therapy. Some of these drugs include Trileptal, which is generally an anti-epileptic and neuropathic pain drug, although off-label use does include treatment of bipolar. This blog will delve into the details of Trileptal for bipolar disorder, side effects, and more.
What is Trileptal (Oxcarbazepine)?
This drug, Trileptal, primarily manages seizures in epilepsy patients by normalizing the electrical activities in the patient’s brain. Trileptal consists of the active ingredient oxcarbazepine. It mainly has the therapeutic effect of treating seizures. Sometimes, it may also be given for mood stabilization in bipolar disorder, but this is through off-label use.
It is from a class of drugs known as mood stabilizers, which have been widely utilized in the management of mood swings that may be present during bipolar disorder.
How Does Trileptal Function in Bipolar Disorder?
For bipolar disorder, the brain becomes imbalanced in neurotransmitters. These changes cause extreme fluctuations in mood, and Trileptal works to modulate neurotransmitters, including sodium and potassium, aiding in the restabilization of the brain’s electrical activity.
This helps stop the onset of high or manic episodes and the low or depressive episodes, which are defining symptoms of bipolar disorder. Although it is not as frequently administered as other drugs like lithium or valproate, in some patients who are sensitive to side effects from other medications, Trileptal works well.
Trileptal for Bipolar Disorder: Benefits
- Effective Mood Stabilization: Trileptal has shown efficacy in stabilizing mood swings, particularly for people who have rapid cycling bipolar disorder or mixed episodes (when symptoms of both mania and depression co-occur).
- Lower Risk of Side Effects: Compared to other anticonvulsants like valproic acid or carbamazepine, Trileptal may have a better side-effect profile, particularly in terms of weight gain, sedation, and cognitive effects, which can be troublesome for people with bipolar disorder.
- Adjunct Therapy: Trileptal may be used alongside other medications like antipsychotics or antidepressants to provide comprehensive treatment for bipolar disorder. It’s often added to a treatment plan when other medications do not offer full symptom control.
- Lesser Drug Interactions: Trileptal usually exhibits fewer interactions with other medications than the anticonvulsant carbamazepine. In polypharmacy settings where many drugs are employed, Trileptal becomes safer.
Dosage of Trileptal for Bipolar Disorder
The dosage varies according to a patient’s conditions, medical history, and responses to treatment. The initial doses for treating bipolar disorder are normally low, starting at about 300 to 600 mg daily, then increased by a doctor based on the patient’s response. Patients usually take two divided doses, ranging between 600 and 1,200 mg a day.
Be sure to follow all the prescription dosages carefully, and never alter the dosage without consulting your healthcare provider. In case the patient decides to stop Trileptal, there is a possibility of severe withdrawal symptoms in addition to the re-emergence of manic or depressive episodes.
Side Effects of Trileptal
Like all medications, Trileptal may cause side effects. These side effects are usually mild to moderate; most people tolerate the drug well. However, some individuals may experience more significant reactions. The common and serious side effects of Trileptal include:
Common Side Effects
- Dizziness or lightheadedness
- Fatigue or tiredness
- Nausea or vomiting
- Headaches
- Double vision or blurred vision
- Coordination issues (ataxia)
- Tremors
Severe Adverse Effects
- Hyponatremia – less than normal sodium levels in the blood. It presents with confusion and fatigue, progressing to severe muscle contraction seizures.
- Skin rashes can be an indication of an allergic reaction.
- Jaundice (yellowing skin or eyes due to liver problems) may occur only in rare cases.
- Serious allergic reactions can occur. Symptoms include swelling in the throat, face, or lips and short and difficult breathing.
You should inform your doctor of any new or unusual symptoms while using Trileptal.
Precautions and Warnings
- Pregnancy and Lactation: Trileptal falls under Category C in the list of FDA-classified drugs. It has been proven that the drug is not safe for the developing fetus. If you are pregnant, planning to become pregnant, or breastfeeding, consult your doctor to discuss the risks and benefits of using Trileptal.
- Alcohol Consumption: Alcohol can increase the sedative effects of Trileptal, leading to greater dizziness, drowsiness, and difficulty concentrating. It is advisable to avoid alcohol or limit consumption while taking this medication.
- Kidney and Liver Function: Trileptal is processed through the liver and kidneys. People with liver or kidney issues should use caution and work with their healthcare provider to adjust the dose if necessary.
- Blood Disorders: Rarely, Trileptal has been associated with low white blood cell count or even a very low platelet count. Routine blood tests may be recommended to monitor your health.
Trileptal vs. Other Mood Stabilizers
Despite its effectiveness, Trileptal does not necessarily have to be considered the first-choice medication for anyone diagnosed with bipolar disorder. Some other mood stabilizers include lithium, valproic acid, and lamotrigine, which are typically preferred because of their reputation in terms of managing bipolar disorders over many years.
The most significant benefit of Trileptal over other mood stabilizers is its improved tolerability and reduced risk of side effects, especially for individuals who have experienced problems with weight gain or cognitive impairment with other medications. However, patients with bipolar disorder have to collaborate closely with their doctor to determine the treatment plan that best suits them.
How PGx Testing Determines if Trileptal is Right for You
PGx testing can be crucial in identifying whether a bipolar patient would appropriately fit into taking Trileptal (oxcarbazepine). PGx testing tests for a patient’s genomic profile in this case to identify their likelihood of metabolizing their drugs. This will then allow better predictions of side effects or no side effects of the treatment. For example, about Trileptal, PGx testing can measure activity with the liver enzyme. This affects how the body metabolizes the drug, and genetic differences could make the drug less effective or increase the chances of adverse reactions. PGx testing ensures safer and more individualized treatment since it allows the tailoring of medication according to genetic factors to reduce trial-and-error approaches in the management of bipolar disorder.
Conclusion
Trileptal (oxcarbazepine) is an effective and well-tolerated drug in managing the symptoms of bipolar disorder. Like every other drug, it’s always an important thing to discuss all the options before deciding on which one to use. It has been a joy of many patients diagnosed with bipolar disorder who have made use of Trileptal under the care of their health providers and changing as many have enjoyed good mood stability and a better quality of life.
If you or any family member has been diagnosed with bipolar disorder, consult a mental health professional to determine which treatment would best suit the needs of an individual.
