You might be thinking, "Oh, how can you use anticonvulsant medication for a mental illness?" That's a very reasonable question. Many people wonder about this. But in fact, when treating a mental condition called bipolar disorder, this type of medication called 'Anticonvulsant' plays a very important role. These are also called 'mood stabilizers', which means they stabilize the mood . So let's learn more about this today. Let's talk in simple terms about why these medications are given, what are the most commonly used types, and what you need to know when using them.
Why are these anticonvulsant drugs given for bipolar disorder?
Simply put, these medications work by calming down the overactive brain. Think of our brains as traffic on a busy road. In a person with bipolar disorder, this activity sometimes becomes too fast, as if the cars are about to collide. We call this state 'mania'. At other times, this activity suddenly becomes paralyzed and stuck. We call this 'depression'.
Anticonvulsant drugs act like traffic lights. They control the excessive electrical activity of nerve cells in the brain, balancing the extremes of rapid and sudden stops. This is why these drugs are also used to treat epilepsy, migraines, and other conditions associated with hyperactivity in the brain.
In the past, these medications were only prescribed to people who did not respond to lithium, the main medication for bipolar disorder. But today, they are widely used alone, with lithium, or in combination with other medications. They are especially effective in people who alternate between mania and depression more than four times a year (we call this ' rapid cycling ' ).
Commonly prescribed anticonvulsants and their differences
There are several types of anticonvulsants used for bipolar disorder. Each one works in a slightly different way. So your doctor will determine the best medication for your symptoms. Let's take a look at the main types of medications used.
| Drug Name | Main use case | Important notes |
|---|---|---|
| Valproic acid / Divalproex sodium (Depakote, Depakene) | To control mania | More effective for manic symptoms than depressive symptoms. Used more for the management of an acute episode. |
| Carbamazepine (Tegretol) | To control mania | Valproic acid is also more effective in manic episodes. It is used to control the current illness. |
| Lamotrigine (Lamictal) | To control depression and prevent relapse | More effective in depressive states than manic states. Often used as a preventative to prevent future episodes of illness. |
In addition to these main medications, doctors sometimes use other anticonvulsants (e.g., Lyrica, Neurontin, Topamax) 'off-label' for other problems associated with bipolar disorder, such as sleep problems, anxiety, pain, or weight loss. 'Off-label' means that the drug is used for something other than the main reason it was approved.
The important thing is that because each of these medications works differently, your experience may vary depending on the medication you take. Don't expect immediate results from taking these medications. In fact, it can take several weeks for these medications to start working at their peak effectiveness .
What are the side effects you should know about?
Like any medication, anticonvulsants can have side effects. That's why it's important to use these medications exactly as your doctor tells you, and under his or her supervision .
While you are taking this medicine, your doctor may ask you to do blood tests from time to time. This is because some anticonvulsants can affect the liver and kidneys. They can also reduce the number of platelets, which help blood clot. These blood tests are done to make sure everything in your body is healthy.
These are some of the most common side effects :
The best part is that most of these side effects will subside over time as your body adjusts to the medication. But if you are having any major concerns about them, never make decisions on your own and always talk to your doctor .
Things to pay particular attention to
There are several things that you and your doctor need to pay attention to when using these medications.
- Pregnancy: If you are pregnant, or planning to become pregnant, it is important to tell your doctor. Some anticonvulsants can affect the unborn baby and increase the risk of birth defects . Therefore, avoid taking them without medical advice.
- Liver health: Some medications can affect the liver when used long-term. This is why your doctor will monitor your liver function by doing blood tests from time to time.
- Problems with other medications: This is a very important point. Anticonvulsants can interact with other medications you are taking and cause serious problems. This can include the common pain reliever aspirin. Therefore, tell your doctor about all the medications you are taking, including vitamins, herbal supplements, and over-the-counter medications . Don't start anything new without asking your doctor.
- Stopping medication:
- Anticonvulsant medications for bipolar disorder control hyperactivity in the brain and stabilize mood.
- Various medications are especially effective for treating mania or depression and preventing relapse. Your doctor will choose the medication that is best for you.
- It is important to be patient as it takes several weeks to feel the full effect of these medications.
- Tell your doctor about all other medications, vitamins, and herbal products you are taking.
- Don't worry about side effects, but if you're concerned about them or if you develop new symptoms, talk to your doctor right away.
- Never stop taking these medications suddenly without medical advice.
Do not stop taking this medication suddenly without your doctor's advice for any reason. If you do stop taking it suddenly, you may be at risk of having a seizure, even if you have never had one. If you do stop, you should do so gradually, reducing the dose and under the supervision of your doctor.
