Topiramate
Introduction To Topiramate
Topiramate is a medicine used to treat epilepsy (seizures) and to prevent migraines. It is also used in the treatment of Lennox-Gastaut syndrome (a rare, but severe form of epilepsy that starts in early childhood).
Topiramate may be taken with or without food, preferably at the same time, each day. If you have missed a dose, take it as soon as you remember it and finish the full course of treatment even if you feel better. Stopping the medication suddenly without talking to your doctor may cause an increased frequency of seizures. Your doctor may advise regular monitoring of serum bicarbonate levels while you are taking this medicine.
Some of the common side effects of this medicine include nausea, taste change, fatigue, diarrhea, weight loss, loss of appetite, and memory impairment. It may also cause vision problems like myopia or glaucoma, so it is important to get your eyesight checked before you start the treatment and regularly thereafter. You may experience dizziness and sleepiness, so do not drive or do anything that requires mental focus until you know how this medicine affects you. Please consult your doctor if these side effects bother you or do not go away.

Benefits of Topiramate
Epilepsy/Seizures
Topiramate is an anticonvulsant (or anti-epileptic) medicine that works by
decreasing the nerve impulses which cause the seizures. By controlling the
frequency of seizures, it will help you go about your daily activities with
more confidence. It helps reduce symptoms such as confusion, uncontrollable
jerking movements, loss of awareness, and fear or anxiety.
This medicine is not associated with any physical or psychological dependence
(addiction) but it should not be stopped suddenly. It must be taken regularly
as prescribed to be effective. Missing doses may trigger a seizure.
Prevention of Migraine
It is not fully established how Topiramate helps prevent migraines. It may
change the abnormal and excessive activity of the nerve cells in the brain or
increase the activity in a region of the brain associated with migraines. By
preventing and reducing the frequency of headaches, it can help you carry out
your daily activities and have a better quality of life.
Lennox–Gastaut syndrome
Lennox-Gastaut syndrome (LGS) is a rare but severe form of epilepsy that
usually starts in early childhood. Affected children may experience several
different types of seizures. Topiramate helps prevent and control these
seizures by decreasing the nerve impulses which cause the seizures.

Frequently Asked Questions
Q. For how long do I need to take Topiramate?
The dose and duration of this medicine will depend on your doctor’s advice. Topiramate does not cure your condition (seizures/migraine) but prevents them from occurring. So, you may have to keep taking it for months or years depending on improvement in your symptoms and side effects that may occur.
Q. Is Topiramate good for anxiety?
Topiramate is not indicated for the treatment of anxiety. Please consult your doctor before taking the medicine.
Q. What are the serious side effects of Topiramate?
Serious side effects of Topiramate are rare. The serious effects of Topiramate may include glaucoma (difficulty in seeing, eye pain, and blurred vision), kidney stones (sharp pain in your sides or lower back), and metabolic acidosis (tiredness, loss of appetite, irregular and faint heartbeat). Other serious side effects of Topiramate could be suicidal thoughts and insufficient sweating (some children taking Topiramate may not sweat enough in hot weather, causing their body temperatures to rise).
Q. I am taking valproic acid for fits. Will Topiramate interfere with the working of valproic acid?
Can this combination be taken? Topiramate does not interfere with the working of valproic acid, but it increases the risk of getting excess levels of ammonia in the blood (hyperammonemia). Increased levels of ammonia in the blood can be dangerous and may cause difficulty in thinking, remembering information, or solving problems. It may also decrease your alertness and make you feel very sleepy with low energy. Immediately inform your doctor if you notice these symptoms. It is important to know that, in rare cases, Topiramate alone can cause hyperammonemia.
Q. Can Topiramate be used in children?
Yes, Topiramate is used for seizures in children more than 2 years of age. However, because of the lack of any reports, this medicine is not recommended to be used in children for migraines. Q. Since I have started using Topiramate people are saying that I have lost weight. Is it because of Topiramate or something else for which I should get investigated? It could be due to Topiramate because Topiramate commonly causes weight loss probably due to a decrease in appetite. If you still have any doubts, talk to your doctor who will advise you appropriately.
