1. How does Topamax (Topiramate) work?
Topamax, known generically as Topiramate, is a prescription drug primarily used as an antiepileptic agent and for migraine treatment.
Given that migraine and epilepsy share some pathophysiological properties, it’s thought that Topiramate exhibits similar mechanisms of action in both disorders.[1] While the exact mechanisms are still unknown, it’s believed to possess key properties that contribute to its success as an effective anti-epileptic and headache medicine:
It’s thought to block certain pathways (voltage-dependent sodium channels) that nerves use to send signals, which help calm excessive nerve activity. Additionally, it may boost the effectiveness of gamma-aminobutyrate (GABA), a neurotransmitter that helps to reduce nerve activity.[2]
Topiramate is also believed to play a role in weight loss by influencing the brain’s reward pathways related to food, stimulating fat breakdown enzymes, and reducing leptin and blood sugar levels.[3]
2. How do you take Topamax (Topiramate)?
This prescription medication is taken orally, and the exact dosage will depend on your prescription. Topamax pills or tablets may not be broken due to their bitter taste. Alternatively, Topamax sprinkle capsules can be swallowed whole or sprinkled onto soft food, with the mixture consumed immediately without chewing.
It can be taken with or without meals. For those with renal impairment, a reduced dosage may be advised.
If you miss a dose, you may take it as soon as you remember, unless you’re six hours close to your next dose. Never double up on your Topamax dosage. If multiple doses are missed, consult your doctor for guidance.
Importantly, do not stop taking Topamax (Topiramate) suddenly, especially if you’re managing epilepsy. Your doctor will advise on a safe method to gradually discontinue it.
3. Who can take Topamax (Topiramate)?
Topamax (topiramate) may be prescribed for various age groups and conditions.
It may be given as an initial monotherapy for the treatment of partial-onset or primary generalised tonic-clonic seizures in patients aged two years and older. Additionally, it may serve as adjunctive therapy for the treatment of partial-onset seizures, primary generalised tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome in the same age group.[4]
It’s essential for patients considering Topamax (Topiramate), especially women planning pregnancy, to consult their doctor. Your doctor may advise taking a higher dose of folic acid at least three months before pregnancy to reduce the risk of certain birth defects.[5]
4. Side effects of Topamax (Topiramate)
Just like many anti-epileptic prescription drugs such as lamotrigine, you need to be aware of the possible side effects of taking Topamax (Topiramate).
Common side effects include tingling in the arms and legs, decreased appetite, nausea, changes in how foods taste, diarrhea, weight loss, nervousness, and an upper respiratory tract infection.
You might also experience tiredness, loss of appetite, an irregular heartbeat, impaired consciousness, high blood ammonia levels, or a low body temperature. Topiramate is also associated with ocular emergencies, so anyone experiencing changes in vision or eye pain should seek immediate medical attention.
Please note that this list does not cover all possible side effects of Topamax (Topiramate). For a comprehensive understanding, it’s best to consult with your doctor.
5. Topamax (Topiramate) and other medications
Topamax (Topiramate) may interact with various medications.
For example, common over-the-counter medications like aspirin, ibuprofen, and naproxen may interact with Topamax (Topiramate). At high doses, Topamax (Topiramate) may also reduce the effectiveness of oral contraceptives. It’s important to disclose all the drugs and supplements you’re taking to your doctor.[6]
6. Medicines you should not use with Topamax (Topiramate)
Caution is advised when using Topamax (Topiramate) with amitriptyline, as it can reduce amitriptyline’s clearance in the body. Moreover, if you’re on carbamazepine, dose adjustments might be necessary due to its interaction with Topamax (Topiramate).
It’s also recommended to avoid using Topamax (Topiramate) with carbonic anhydrase inhibitors like acetazolamide, dorzolamide, and brinzolamide to prevent increased risks of metabolic acidosis and nephrolithiasis.
Additionally, using central nervous system (CNS) depressants such as benzodiazepines, alcohol, thalidomide, and bromperidol in combination with Topamax (Topiramate) may be avoided or approached with extreme caution, as it can lead to enhanced sedation and CNS depression.[7]
