A substitute contains the same active ingredient (salt), in the same strength, as Topamac 100 mg Tablet. The medicine inside is the same — the brand name, manufacturer and price are what differ.
All medicines sold in India, branded or generic, must meet the quality standards set by the national drug regulator (CDSCO). A lower price does not mean lower quality.
Please confirm with your doctor or pharmacist before switching brands — they will check that the strength and form match your prescription.
Topamac 100 mg Tablet contains Topiramate (100mg). It belongs to the Anticonvulsant class of medicines.
Trigeminal neuralgia Epilepsy/Seizures Lennox–Gastaut syndrome Migraine
TOPAmac 100mg Tablet is an antiepileptic medication. It controls seizures or fits by decreasing the abnormal and excessive activity of the nerve cells in the brain.
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. TOPAmac 100mg Tablet may be taken with or without food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of TOPAmac 100mg Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine can cause deep unconsciousness, slowed breathing and dangerous heart rhythm disturbance. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Topamac are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Never stop or change an anti-epileptic on your own. Stopping abruptly can cause prolonged, dangerous seizures. Sodium valproate and divalproex must not be used by anyone who is pregnant or could become pregnant unless a specialist has confirmed there is no alternative — they cause serious birth defects and developmental problems. Effective contraception is essential. Seek urgent care for any rash, especially in the first weeks — a rash with fever, blistering or peeling can be life-threatening. Report yellowing of the eyes or skin, persistent vomiting, unusual bruising or severe tiredness at once. Tell your doctor about any change in mood or any thoughts of harming yourself. Take the same brand each time unless your neurologist has agreed to a change; switching can alter seizure control.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Valproate-containing medicines are contraindicated in pregnancy for epilepsy unless no alternative exists, and in all women of childbearing potential without a pregnancy prevention programme. Several are not suitable in significant liver disease.
This group interacts very widely, including with contraceptives, blood thinners and other anti-epileptics. Give your doctor a full list of what you take. Hormonal contraception may become unreliable — ask your doctor which method to use.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Take your medication regularly as directed by your doctor as missing doses can trigger seizures. Do not change the brand of your medicine and make sure that you have sufficient amount of medicine present with you. Some healthy tips to prevent seizures: Practice yoga every day. Get enough sleep at nighttime. Limit the use of screen time such as mobile/laptop. Take your medication on time. It may cause dizziness and sleepiness. Do not drive or do anything that requires mental focus until you know how it affects you. Keep yourself hydrated by drinking plenty of fluids throughout the day while taking TOPAmac 100mg Tablet. This can reduce the risk of kidney stones. Monitor your weight during treatment with this medicine as it can cause weight gain. Talk to your doctor if you notice sudden mood changes or develop suicidal thoughts. Do not stop taking the medication suddenly without talking to your doctor as it may increase the seizure frequency.
