Has your doctor prescribed Topiramate to you or someone in your family? This medication is often prescribed to control seizures, or "fits" as we call them, caused by epilepsy, or to prevent frequent, severe migraine headaches. You may have questions, curiosity, and perhaps even a little fear about this medication. That's normal. So today, let's talk about this medication, its effects, side effects, and things to be aware of when using it, all in a simple, understandable way.
Simply put, what is Topiramate?
Think of our brain as a telephone system in a busy city. Messages are constantly going back and forth. But sometimes, because of some problem in this messaging system, messages start to flow in an unnecessary, rapid, and uncontrolled manner. A seizure is one such condition. Migraines are also caused by this kind of hyperactivity of the nervous system.
Topiramate works by calming the overactive nerves . That is, it helps to control the rapid transmission of messages and return the brain to normal function. When it comes in Extended-Release (XR) capsules, the medication is released into the body gradually throughout the day. So it is only necessary to take it once a day.
Things you need to tell your doctor before starting medication
This is a very important part. Even if you just think, "I'm fine," it can still affect this medication. So, if you have any of the following conditions, be sure to tell your doctor before starting the medication.
- Kidney disease or kidney stones: This medicine is eliminated from the body through the kidneys. So if you have kidney problems, your dosage may need to be adjusted.
- Lung disease or breathing difficulties: Sometimes this medicine can affect the acid levels in the body.
- If you are a regular drinker: The combination of alcohol and this medication may increase side effects.
- If you or someone in your family has had depression or suicidal thoughts , this is very important.
- If you have a bleeding disorder .
- If you are pregnant, trying to get pregnant, or breastfeeding: This medicine may be dangerous during pregnancy. We will talk about that in more detail.
- If you have previously had an allergy to topiramate or any other medicine or food .
Talking honestly with your doctor about your health history is very important for your own safety.
How exactly do I use this medicine?
As the doctor says, it is very important to take the correct dosage at the correct time.
1. Swallow whole: Since this is an Extended-Release (XR) capsule, do not break, chew, or crush it. Doing so could cause the body to absorb the entire dose of medicine that you should be taking throughout the day, which could cause dangerous side effects. Swallow the capsule whole with a glass of water.
2. Before or after food?: You can take this medicine with or without food. However, if you experience stomach upset, it is better to take it with food.
3. Take your medicine at the same time every day: Try to take your medicine at the same time every day as much as possible. This will help keep the levels of the medicine in your body consistent.
4. Don't stop suddenly: This is the most important thing to remember. Do not stop taking this medicine suddenly for any reason without consulting your doctor. If you do, the seizure may become uncontrollable and severe. If you do stop, your doctor will gradually reduce the dose.
What if the dosage of the medicine is increased? What if a dose is missed?
- Overdose: Suppose you have taken more than the prescribed dose. If this happens, do not delay. Immediately go to the Emergency Department (ETU) of the nearest hospital. Or call the National Poison Information Center at the Colombo National Hospital .
- Missed Dose: If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose (e.g., within a few hours), skip the missed dose and take your next dose at the scheduled time. Never take two doses at the same time to make up for a missed dose.
There are other things you should be aware of when taking this medicine.
This medicine can have a small impact not only on your body, but also on your daily life.
- Driving and activities requiring alertness: This medication may cause drowsiness, dizziness, and difficulty concentrating in some people. Therefore, avoid activities requiring alertness such as driving, working at heights, and operating machinery until you know exactly how this medication affects you.
- Alcohol: Taking this medication with alcohol can increase side effects such as drowsiness and dizziness. Therefore, talk to your doctor about alcohol consumption while taking this medication.
