ETHEX Corporation has voluntarily recalled three specific lots (77946, 81141 and 81142) of Dextroamphetamine Sulfate 5 mg tablets, as a precaution, due to the possible presence of oversized tablets. Oversized tablets may contain as much as about twice the labeled amount of the active ingredient. The recalled lots were distributed by ETHEX Corporation under an “ETHEX” label between January 2007 and May 2008. The 5 mg product is an orange round tablet debossed with “ETHEX” and “311” on one side. If someone were to take a higher than expected dose of Dextroamphetamine Sulfate, then the risk of adverse effects known to be associated with the drug such as tachycardia, hypertension, tremors, decreased appetite, headache, insomnia, dizziness, blurred vision, stomach upset, and dry mouth may be increased. No report of any oversized Dextroamphetamine Sulfate tablets has been received by ETHEX from any wholesaler, retailer, consumer or caregiver, and ETHEX has not received any report of unexpected side effects or injury related to this product. ETHEX Corporation is conducting this precautionary, voluntary recall because it found a small number of oversized tablets in lots which had not yet been distributed. These oversized tablets were removed before the lots were distributed. This recall is being conducted with the knowledge of the U.S. Food and Drug Administration (FDA).
