Children's Guaifenesin Grape Liquid and Guaifenesin DM Cherry Liquid by Perrigo Company: Recall - Potential Defect with Dosage Cup

Jan 13, 2016

Audience: Consumer

Including store brands:

  • Sunmark  
  • Rite-Aid  
  • Topcare  
  • Kroger  
  • GoodSense  
  • Dollar General
  • Care One  
  • CVS

ISSUE: Perrigo Company announced that, following the recent recall of certain dosing cups by its supplier, it has initiated a voluntary product recall in the US to the retail level of 2 batches of its children's guaifenesin grape liquid (100mg/5 mL) and 3 batches of its children's guaifenesin DM cherry liquid (100mg guaifenesin and 5mg dextromethorphan HBr/ 5 ml) sold in 4 oz. bottles with dosage cup in a box under multiple store brand product names. Some packages contain an oral dosing cup with incorrect dose markings. See the press release for affected label and lot numbers.

At risk populations such as those who are poor metabolizers of dextromethorphan may experience an overdose by a factor of 3, if incorrect measuring levels are used.

Consumers should be aware that an overdose of Guaifenesin DM may cause hyper excitability, rapid eye movements, changes in muscle reflexes, ataxia, dystonia, hallucinations, stupor, and coma. Other effects have included nausea, vomiting, tachycardia, irregular heartbeat, seizures, respiratory depression, and death. Small children who are poor metabolizers of dextromethorphan and use the product regularly over a period of several days at the mistaken dose, may develop cumulative toxicity. Moreover, adverse reactions to guaifenesin when given in high or excessive dosage may include nausea/vomiting, diarrhea, and/or abdominal pain. Therefore, an extreme overdose in an at risk population may need medical intervention, but in most cases adverse health consequences are temporary and reversible.

BACKGROUND: These recalled products are sold by distributors nationwide and distributed through retail stores.

RECOMMENDATION: Gastric decontamination is recommended after acute ingestion of greater than 10 mg/kg, if administered soon after ingestion.

Consumers that have product with the corresponding labels and batch numbers listed in the Press Release should discard the dosing device and product and may call Perrigo, toll free, Monday through Friday from 8:00 AM to 10:00 PM EST, at 1-888-345-0479, or visit mucusreliefrecall.com. Consumers should contact their physician or healthcare provider if they have any questions, or if they or their children experience any problem that could possibly be related to this drug product.

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:

Guaifenesin (Unapproved) Timed-Release Drug Products

May 25, 2007

Audience: Consumers, healthcare professionals

[Posted 05/25/2007] FDA informed consumers and healthcare professionals of its intent to take action against companies that market unapproved timed-release dosage form of guaifenesin products, a substance commonly used in medicines to relieve cough and cold symptoms by stimulating removal of mucous from the lungs. These dosage forms are often described as extended-release, long-acting or sustained-release products that release their active ingredients over an extended period of time, reducing the number of doses needed per day. Approximately 20 firms make unapproved timed-release products containing guaifenesin that have not undergone FDA review for safety and efficacy. Mucinex, Mucinex-D, Mucinex-DM, and Humibid are the only FDA approved timed-release guaifenesin (single ingredient or combination) products. Companies marketing unapproved products containing guaifenesin in timed-release form are expected to stop manufacturing them within 90 days and must cease shipping them in interstate commerce within 180 days. This action does not affect products containing guaifenesin in immediate release form.

Dextromethorphan

May 23, 2005

Audience: Healthcare professionals and consumers

FDA issued a Talk Paper to notify the public about the abuse of dextromethorphan (DXM), an ingredient found in many over-the-counter (OTC) cough and cold remedies. The agency is working with other health and law enforcement authorities to address this serious issue and warn the public of potential harm, after five recently reported deaths of teenagers that may be associated with the consumption of powdered DXM sold in capsules.
