Topamax (topiramate) is licensed for epilepsy monotherapy and adjunctive therapy and, separately, for adult migraine prophylaxis, and buyers can specify the Janssen-Cilag brand or a licensed generic tablet against the same tender line.
Topamax (topiramate), originated by Janssen-Cilag, is an oral sulfamate-substituted anticonvulsant used both as an epilepsy therapy and, at a lower dose range, as a preventive treatment for migraine. M Care Exports is a merchant exporter: we source Topamax and licensed generic topiramate tablets and sprinkle capsules through Indian distribution and manufacturing channels and dispatch on quote, not from our own manufacturing.
Topiramate exporter and bulk supplier from India.
Tell us the strength mix, dosage form, brand-or-generic preference, indication (epilepsy or migraine prophylaxis) and destination market, and we quote against your specification, drawn from licensed WHO-GMP manufacturer lines on the M Care roster. Because topiramate's titration schedule and target dose differ substantially between epilepsy and migraine prophylaxis, we confirm which indication a tender or formulary line is written for before we release a quote, then align CTD/eCTD or country-specific dossier paperwork to the destination regulator's requirements.

Sulfamate-substituted monosaccharide anticonvulsant, sourced and documented for export.
Topiramate is a sulfamate-substituted monosaccharide with several proposed mechanisms, including sodium-channel blockade, enhancement of GABA-A activity and antagonism of AMPA/kainate glutamate receptors, which together raise seizure threshold and are thought to underlie its separate migraine-preventive effect. It is dosed orally, not injected, and needs no reconstitution. Topamax's FDA-labelled indications are monotherapy in patients aged 2 years and over with partial-onset or primary generalised tonic-clonic seizures, adjunctive therapy for those same seizure types plus Lennox-Gastaut syndrome, and, separately, prophylaxis of migraine headache in adults. The UK SmPC extends monotherapy down to age 6 rather than 2. It is not licensed for acute migraine treatment or for absence seizures. Topamax is supplied as 25 mg, 50 mg, 100 mg and 200 mg coated tablets and as 15 mg and 25 mg sprinkle capsules, which can be opened and the contents sprinkled on soft food for patients unable to swallow tablets.

Hospital pharmacies, licensed importers and tender desks across our export markets.
India is our origin. We do not sell into the Indian market.
Buyers for topiramate are hospital and community epilepsy pharmacies managing patients on chronic anticonvulsant therapy, neurology and headache clinics prescribing it for migraine prophylaxis, national and regional MoH tender desks running neurology and CNS formulary lists, licensed pharmaceutical wholesalers and importers, and NGO or foundation programmes supporting epilepsy-care access in markets where local registration is in place.
GCC registration routes
Supply against MoH registration held by your local licensed importer, or via the GCC central registration pathway.
UK unlicensed routes
Where no UK licence exists, the MHRA Specials and named-patient import routes cover clinically justified demand.
Tender desks
Bid-pack documentation assembled to the tender's specification, from CoPP to batch records.
Dossier support
CTD documentation from the sourcing manufacturer, compiled for your regulator's format.
What the dispensing pharmacist checks on topiramate.
Topiramate is titrated slowly and in opposite directions depending on indication: epilepsy dosing builds toward 200 mg to 400 mg daily in adjunctive adult regimens, while migraine prophylaxis targets a much lower 100 mg daily, so confirm which indication a prescription is written for before assuming a dose looks wrong. Renal impairment below 70 mL/min creatinine clearance halves both the starting and maintenance dose on the FDA and UK labels alike. Counsel patients on cognitive slowing, word-finding difficulty and mood change, which the pivotal trials recorded in a substantial minority at higher doses, and on staying well hydrated in hot weather given a real risk of oligohidrosis and hyperthermia, particularly in children. Sudden eye pain or blurred vision in the first month of treatment needs same-day review for acute myopia with secondary angle-closure glaucoma. Teratogenicity counselling on cleft lip and palate risk is essential for anyone of childbearing potential, and metabolic acidosis warrants a baseline and periodic serum bicarbonate check.
The documentation pack a regulator actually asks for.
As an oral tablet and sprinkle-capsule dosage form, topiramate travels on standard ambient logistics rather than the validated cold-chain lanes M Care runs for biologics and insulins; both the FDA and UK labels specify storage below 25 to 30 degrees Celsius with protection from moisture. Topiramate does not appear on the WHO Model List of Essential Medicines for epilepsy, which lists carbamazepine, phenobarbital, phenytoin, valproic acid and, since 2017, lamotrigine; WHO's own committee documentation records that topiramate was considered as a second-line addition and not selected, so tender desks should treat it as a formulary-specific rather than EML first-line agent. On the brand-versus-generic question, Topamax remains the originator product from Janssen-Cilag. FDA-approved generic topiramate tablets from multiple manufacturers, including Aurobindo, Zydus and Torrent, are separately registered in the US, and UK-licensed generic topiramate tablets and capsules sit alongside the Janssen-Cilag brand, so buyers genuinely have a brand-or-generic choice; M Care quotes either against the tender specification and destination-market registration status. A UK Parliamentary written question in September 2025 recorded an ongoing supply issue across all four strengths of topiramate tablets, with resupply from the affected manufacturers unconfirmed and alternative-manufacturer stock used to bridge demand, which we treat as a live example of why formulary desks keep a secondary export source on file.

Topiramate supply, the specific questions.
Does a generic version of Topamax exist?
Yes. FDA-approved generic topiramate tablets are registered and marketed in the US alongside Janssen-Cilag's Topamax, including from manufacturers such as Aurobindo, Zydus and Torrent. UK-licensed generic topiramate tablets and capsules are also available alongside the branded product. Registration status varies by destination country, so M Care checks local approval before quoting brand or generic against a specific tender.
Can M Care supply Topamax to our market?
Yes, on an import basis. We source Topamax through Janssen-Cilag's licensed Indian distribution channels and dispatch against your import authorisation and any local registration your pharmacy or hospital holds.
What strengths of topiramate are available?
25 mg, 50 mg, 100 mg and 200 mg coated tablets, and 15 mg and 25 mg sprinkle capsules that can be opened onto soft food for patients unable to swallow tablets. Tell us your indication, dosing protocol and patient population and we quote the strength mix accordingly.
Is topiramate licensed for migraine as well as epilepsy?
Yes, but as two separate licensed uses with different dosing. Topamax is indicated for epilepsy monotherapy and adjunctive therapy, and, at a lower target dose of around 100 mg daily, for prophylaxis of migraine headache in adults. It is not licensed for acute migraine treatment.
Why is topiramate not on the WHO Essential Medicines List?
WHO's expert committee considered topiramate as a potential second-line addition to the epilepsy list but selected lamotrigine instead. The current WHO list for epilepsy covers carbamazepine, phenobarbital, phenytoin, valproic acid and lamotrigine. Tender desks should treat topiramate as a formulary-specific agent rather than a WHO first-line one.
What documentation does M Care provide with a topiramate shipment?
Batch-level certificate of analysis, CDSCO export documentation from the Indian side, and CTD/eCTD-aligned dossier support where the destination regulator requires local registration before import.
