More Trouble for Topamax as it is Recalled

Rate This

A recent study indicated that the anti-epilepsy and migraine drug Topamax was causing birth defects in the babies of mothers who took it during pregnancy. Now the United States Food and Drug Administration (FDA) is recalling two lots of it because it has been contaminated with a chemical preservative and has an offensive odor.

The odor is thought to be 2,4,6 tribromoanisole (TBA), which is a preservative applied to the wooden crates that the medication is transported in.

In January 2010, the FDA put in a place a new rule that suppliers of medicines have to verify that they do not use chemically treated wooden crates. Nonetheless, consumers still identified the offensive odor.

TBA has caused gastrointestinal symptoms in some patients who have taken the tainted medication, although there have been no reported serious adverse events.

The affected tablets are:
Topamax tablets, 100mgs, lot number OKG110
Topamax bottle of 60 tablets, lot number OLG222
The 100 mg tablets are yellow and have ‘OMN’ written on one side and "100" written on the other side.

If you have any medication with an offensive odor, please return it to your pharmacist. You can also call the Topamax line at 866-536-4398 for advice.

Originally prescribed as an anti-seizure medication, Topamax/Topiramate has also been prescribed off-label to prevent migraines and to treat obesity as well. J&J’s recent recall affects a lot of these people, and it brings to light a lot of issues linked to the drug. It was found that pregnant women taking Topamax run the risk of having a child with birth defects such as a cleft lip and/or cleft palate. While this recall is separate from these potential health effects, Topamax lawsuits – http://www.sokolovelaw.com/legal-help/dangerous-drugs/anti-seizure/topamax - have become more frequent. All quality and safety issues considered, I’m interested to watch how the future of this drug plays out. Regards, SK
