How Long Until Topamax Starts Working (Onset of Action)
For migraines: anywhere from one day (don’t get your hopes up, but it happens) to a month.
For epilepsy: it’s complicated.
Likelihood of Working
For migraines: Really good, which is probably why OrthoMcNeil P-Diddy Janssen are all about Topamax for migraines these days.
For epilepsy: pretty good.
How to Take Topamax
For migraines: the initial dose is 25mg a day, increased by 25mg a day each week as needed until you reach 100mg a day, usually divided into two doses.
For epilepsy: the initial dose is 25mg a day, increased by 25mg a day each week until you reach 100mg a day, usually divided into two doses. If you’re still having seizures, the recommended increase is 50mg a day each week until you achieve seizure control or the recommended maximum of 400mg a day.
How to Stop Taking Topamax (Discontinue, Withdrawal)
Topamax’s Pros and Cons
Currently the only modern AED approved by the FDA that you can take by itself to treat both generalized, flopping around tonic-clonic seizures as well as partial seizures. You’re more likely to lose weight than gain weight. Can (but doesn’t always) work for migraines at 25mg a day with barely any side effects after a few weeks. Can (but doesn’t always) work for seizures at 100mg a day.

I <3 Topamax
The promise of losing weight is oversold and often leads to disappointment. Topamax can make you dumber than a box of rocks.
Interesting Stuff your Doctor Probably didn’t Tell You about Topamax
Topamax may encourage you to stop smoking, in that you may just not like to smoke after you start and withdrawal symptoms won’t be as bad. Topamax can mess with lithium levels in seemingly random ways, and taking it along with Depakote or any other valproate can cause hypothermia (excessively low body temperature) and/or hyperammonemia (elevated ammonia in your blood), so taking Topamax to lose medication-induced weight gain can get tricky.

In-Depth Pros & Cons
Topamax’s Side Effects (Adverse Reactions)
Typical Side Effects
Sleepiness, fatigue, and/or lethargy. A pins & needles effect/tingling in the extremities that usually goes away after a week or two - but you want this one if you’re taking Topamax for migraines. Sodas and other carbonated beverages will taste like ass. Memory loss, aphasia (weird words coming out in place of what you meant to say or write), word find problems (not being able to recall the names of people, things or concepts), and a general cognitive impairment that has earned this drug the nicknames “Stupamax” and “Dopamax.”
Uncommon Side Effects
Dry and/or itchy eyes along with assorted vision problems. You may find yourself not able to drink coffee any more, so be prepared to quit the bean. Food in general, and not just carbonated beverages, may not taste quite the same. Frequent, intense déjà vu or jamais vu. If you were experiencing one prior to taking Topamax be prepared to experience the other.
Freaky Rare Side Effects
Tongue paralysis, neverending cough, staghorn calculus (I’d like to know how you do calculus using antlers), and palinopsia and the Alice in Wonderland syndrome. So Topamax explains Sarah Palin?

topiramate’s Half-Life & How Long Until It Clears Your System
Half-life is the average time it takes for you to process half of the drug’s active ingredient. If a drug has a half-life of around 24 hours and you take a dose of 100mg, you’ll have roughly the equivalent a 50mg dose after one day, a 25mg dose after two days, and so on. The rule of thumb is: multiply the half-life by five and you get how long it is for the dose you took to be cleared from your bloodstream, so there’s nothing swimming around to attach itself to your brain and start doing stuff1. That’s called “plasma clearance.” Complete clearance is a complex equation based on a lot of factors which may or may not: be published in the PI sheet, include personal data like your weight, or even completely figured out by corporate and independent researchers. It usually winds up being 2–5 days after plasma clearance no matter what2, but can take weeks. Sometimes a drug will clear from your brain and other organs before it clears from your blood. If we’ve found the complete clearance, or how to calculate it if it requires things like your weight and what your piss looks like, you’ll find that on topiramate’s pharmacokinetics page.
How topiramate Works
the current best guess at any rateTopamax is a fairly broad-spectrum anticonvulsant. It prevents migraines and various types of seizures by blocking voltage-dependent sodium and calcium channels, inhibiting glutamate and carbonic anhydrase, and promoting the reception of GABA and/or increasing the amount of GABA, depending on the location in your brain and the study you read. Topamax may also affect voltage-sensitive sodium channels.

Ratings, Reviews, Comments, PI Sheet, and More
Whichever nickname you use, Dopamax, Stupamax, or a supermodel drug, when it works Topamax is a freaking Godsend. I’m more than happy to put up with the frequent renal calculus (doctorese for the sediment in my piss that is more “kidney sand” and “kidney pebbles” than kidney stones), the hosed memory, the increased problems in getting the right words out of my mouth, and random periods of coffee = panic attacks so I don’t have to worry about having some kind of seizure activity a couple times a week or go through the hell that is ultradian rapid cycling.
With one of the simplest titration schedules and approval to be used as monotherapy (by itself) to treat generalized, flopping on the ground & pissing your pants seizures, Topamax will often be prescribed before Depakote or Stavzor - the newest flavor of valproic acid - even if the side effects for lower dosages of valproates often suck less than the side effects of Topamax at dosages required to treat some of those forms of epilepsy. Topamax side effects might suck more, but it is easier to take, so it’s a hard call as to which really sucks less.

It’s always a good idea to check for drug-drug interactions yourself. Just because most people in the crazy meds business know about really important interactions (e.g. MAOIs and a lot of stuff, warfarin and everything on the planet) doesn’t mean the person who prescribed your meds told you about them, or the pharmacist has all the meds you take at their fingertips like they’re supposed to. Or they have the time to do their jobs properly when not dealing with complete idiots or playing Angry Farmers on the Faecesbooks.

2 For crazy meds. I have no idea what the average complete clearance is for other types of medications. For all I know there are drugs that utterly vanish from your system in under five passes, and others that won't let go of your squishy bits for years after you stop taking them.
3 Thank you! I'll be here all weak. Be sure to tip your content provider. And don't try the veal, it's cruelicious!

If you have any questions not answered here, please see the Crazymeds Topamax discussion board. We welcome criticisms of the articles, notifications of bad links, site problems, consumer experiences with medications, etc. I’m not always able to write back. Hence I never answer questions about meds via e-mail that are answered by this or other articles. Especially if they have been repeatedly asked on the forum. That’s why we write these damn things. Questions about which meds are best for your condition should also be asked on the forum; because this is a free site, so the price of admission is making things easier for somebody else searching for the same answer. We don’t deal with children on the forum or in private because after doing this for ten years I don’t have the emotional stamina to deal with kids who have brain cooties.

Know your sources!
Nobody on this site is a doctor, a therapist, or a pharmacist. We don’t portray them either here or on TV. Only doctors can diagnose and treat an illness. While it’s not as bad as it used to be, some doctors still get pissed off by patients who know too much about medications, so tread lightly when and where appropriate. Diagnosing yourself from a website is like defending yourself in court, you suddenly have a fool for a doctor. Don’t be a cyberchondriac, thinking you have every disease you see a website about, or that you’ll get every side effect from every medication1. Self-prescribing is as dangerous as buying meds from fraudulent online pharmacies that promise you medications without prescriptions.
All information on this site has been obtained through our personal experience and the experiences family, friends, what people have reported on various reputable sites all over teh intergoogles, the medications’ product information / summary of product characteristic (PI/SPC) sheets, and from sources that are referenced throughout the site. As such the information presented here is not intended as a substitute for real medical advice from your real doctor, just a compliment to it. You should never, ever, replace what a real doctor tells you with something from a website on the Internet. The farthest you should ever take it is getting a second opinion from another real doctor. Educate yourself - always read the PI/SPC sheet or patient information leaflet (PIL) that comes with your medications and never ever throw them away. OK, you can throw away duplicate copies, but keep at least one, as that’s your proof of purchase of having taken a med in case a doctor doubts your medical history. Plus they take up less space than a bottle, although keeping one inside of a pill bottle is even better.

1 While there are plenty of books to help you with hypochondria, for some reason there’s not much in the way of websites. Then again, staying off of the Internet is a large part of curing/managing the disorder.
2 Remember kids, Microsloth operating systems are like TOS Star Trek movies with in that every other one sucks way, way more. With TOS Star Trek movies you don’t want to bother watching the odd-numbered ones. With Microsloth OS you don’t want to buy and install the even-numbered ones. Anyone who remembers ME and Vista knows what I mean.
3 Have I mentioned how open source operating systems for commercial applications is one of the dumbest ideas in the history of dumb ideas? I don’t even need my big-ass rant any more. Heartbleed has made my case for me. And that’s just the one that got all the media attention. The very nature of an open source operating system makes security as much of an illusion of anonymity. Before you flip out too much: the domain Crazymeds is hosted on uses a version of SSL that is not affected by the Heartbleed bug. That’s one of the many reasons why I pay a lot of money and keep this site on Lunarpages.
