If you or someone in your family has experienced a serious side effect to a health product, you are encouraged to report the experience to your health care professional (e.g. physician, pharmacist). You could also complete a copy of the side effect reporting form or report your side effect to FDA.

Side effects reports are analyzed to discover potential health product safety signals. Some important reactions may take an extremely long time to develop or occur infrequently. Continued monitoring of adverse reactions is thus essential to maintain a comprehensive safety and effectiveness profile of health products.

Topamax Side Effects Reported to FDA

The following Topamax reports list potential signals of serious risks and new safety information that were identified using the FDA Adverse Event Reporting System (FAERS).
FAERS is a database that contains information on adverse event and medication errors reports submitted to FDA by healthcare professionals (such as physicians, pharmacists, nurses and others), consumers (such as patients, family members, layers and others) and manufacturers.


The appearance of Topamax on this list does not mean that FDA has concluded that the drug has the listed risk. It means that FDA has identified a potential safety issue, but it does not mean that FDA has found a causal relationship between the drug and the listed risk.

    Topamax (topiramate): Recall - Musty Odor

    [Posted 04/15/2011]

    AUDIENCE: Risk Manager, Pharmacy, Patients

    ISSUE: Ortho-McNeil Neurologics Division of Ortho-McNeil-Janssen Pharmaceuticals, Inc., is recalling two lots of Topamax (topiramate) 100mg Tablets. The recall stems from four consumer reports of an uncharacteristic odor thought to be caused by trace amounts of TBA (2,4,6 tribromoanisole). While not considered to be toxic, TBA can generate an offensive odor and a small number of patients have reported temporary gastrointestinal symptoms. There have been no reported serious adverse events caused by the presence of TBA in Topamax.

    BACKGROUND: Topamax is indicated as initial monotherapy in patients 10 years of age and older with partial onset or primary generalized tonic-clonic seizures; as adjunctive therapy for adults and pediatric patients ages 2 − 16 years with partial onset seizures, or primary generalized tonic-clonic seizures, and in patients 2 years of age and older with seizures associated with Lennox-Gastaut syndrome; and for adults for the prophylaxis of migraine headache.

    RECOMMENDATION: Patients taking Topamax 100mg Tablets who experience an uncharacteristic odor associated with their medication should return the tablets to their pharmacist, and contact their healthcare professional if they have questions.

    Healthcare professionals and patients are encouraged to report adverse events or side effects related to the use of these products to the FDA's MedWatch Safety Information and Adverse Event Reporting Program:

    • Complete and submit the report Online: www.fda.gov/MedWatch/report.htm
    • Download form or call 1-800-332-1088 to request a reporting form, then complete and return to the address on the pre-addressed form, or submit by fax to 1-800-FDA-0178
