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 (eg, physician, pharmacist). Your health care provider can provide additional clinical information and complete a copy of the side effect reporting form.

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.

Sulfa Side Effects Reported to FDA

The following Sulfa 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 Sulfa 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.

    Ferrous Sulfate Tablets, 325 mg Labeled as Rugby Natural Iron Supplement: Recall - Bottle May Contain Meclizine HCl 25 mg Tablets


    [Posted 01/18/2013]

    AUDIENCE: Pharmacy, Consumer

    ISSUE: Advance Pharmaceutical Inc. notified the public of a recall of one lot of Ferrous Sulfate Tablets 325 mg, after notification by a pharmacist that a bottle of Ferrous Sulfate Tablets, 325 mg contained Meclizine HCl 25 mg tablets. The lot of the Rugby Ferrous Sulfate is 12G468. Expiration date for the lot is 07/14. The lot was manufactured and packaged in 100 count bottles by Advance Pharmaceutical Inc. under the label of Rugby NATURAL IRON SUPPLEMENT Ferrous Sulfate -- see Product Photo page. Meclizine toxicity may lead to dose-related serious adverse events, including impaired alertness, drowsiness, confusion, low blood pressure, coma, and respiratory depression. Without supportive treatment meclizine toxicity has the potential to be life-threatening.

    BACKGROUND: Taking Meclizine HCl 25 mg as Ferrous Sulfate 325 mg may cause serious side effects to those who consume alcohol or other sedatives, those with a pre-existing CNS disorder, those with kidney or liver dysfunction, the elderly, nursing infants of lactating mothers who received the drug and newborns of mothers who received the drug immediately before childbirth.

    Consumers who take three tablets daily of the defective product for treatment of iron deficiency would be inadvertently ingesting 75 mg of meclizine HCl daily, which is close to the maximum daily adult dose in prescription meclizine drug products of 100 mg. Consumption of meclizine three times a day instead of once daily as monograph recommended is likely to lead to significant drug accumulation because it is a long-acting drug with effects that may persist up to 24 hours after a single dose.

    RECOMMENDATION: Consumers who have the affected lot should not take the product. They may contact Advance Pharmaceutical with questions at 631-981-4600, Ext.300, Monday through Friday between 8:30 am and 4:30 pm ET.
