The FDA has approved production of topiramate, the generic version of migraine preventive drug Topamax. It will be available in multiple strengths from 17 different manufacturers.
This is great news for the many people who have found relief from migraines or headaches with Topamax. Except for the side effects, which many find intolerable, Topamax is often called as a “miracle drug.” I don’t believe in miracle drugs, but one that can help so many people is pretty impressive.
Ortho-McNeil Neurologic’s patents on Topamax began expiring last year.

Tablet and injection versions of generic Imitrex (sumatriptan) are available in the US. Doses are 25mg, 50 mg, and 100mg tablets and 4mg and 6mg injections (kits or pre-filled syringes). Patients have reported prices between $35 and $200! Imitrex’s patent doesn’t actually expire until February; a reader suggested it might be less expensive then.
The generic hasn’t been as effective as the brand name drug for some patients. In Generic Imitrex (Sumatriptan) — Is it as Effective as Brand Name Imitrex, blogger Doc Shazam writes:
…I have taken 2 of “Dr. Reddy’s” generic sumatriptan tablets with almost no relief of headache symptoms, but a plethora of side effects, including aching muscles, nausea, “light headed” feeling and general dis-ease.

The generic version of Imitrex Injection (called sumatriptan) is now shipping in the US. I don’t know if it is available in other countries, nor do I know when/if the tablets will be available. I doubt all pharmacies have it in stock yet. I recommend calling your pharmacy before taking your prescription in.
From Par Phamaceutical’s press release:
Par Pharmaceutical Begins Shipment of Sumatriptan Injection
November 6, 2008 – Par Pharmaceutical Companies, Inc. today announced that it will begin shipping generic versions of Imitrex® Injection (sumatriptan succinate injection) 4mg and 6mg starter kits and 4mg and 6mg prefilled syringe cartridges to the trade immediately. In addition, Par anticipates launching the 6mg vials early next year.
Sumatriptan, the generic form of Imitrex, is scheduled to be available by the end of 2008. Although Imitrex is available as a tablet, nasal spray and injection, sumatriptan will only be available in tablets of 25, 50 or 100 mg. It will be distributed by Ranbaxy.
GlaxoSmithKline no longer offers coupons for Imitrex. In the meantime, you can save on the pricey prescription by signing up for $25 off Imitrex coupons from GlaxoSmithKline. I was skeptical because your mailing address is required to receive the coupons. I signed up a couple years ago and it hasn’t been intrusive. Mailings are about four times a year and there’s no indication they’ve sold my address.
