Cyclobenzaprine HCl and Amantadine HCl by Apace Packaging: Recall - Potential Mislabeling

Jul 28, 2017

Audience: Pharmacy, Health Professional

ISSUE: Apace Packaging LLC is voluntarily recalling one lot of Cyclobenzaprine HCl Tablet, USP 5 mg 50ct Unit Dose, NDC# 50268-190-15, Lot Number 16710 and one lot of Amantadine HCl Capsule, USP 100 mg 50ct Unit Dose NDC# 50268-069-15, Lot Number 16710 to the Retail level. These products have been recalled due to a potential mislabeling. A small number of cartons containing Cyclobenzaprine HCl Tablets 5 mg UD Blister Cards may potentially be mislabeled as Amantadine HCl Capsules, USP 100 mg. The unit dose blisters inside the carton are correctly labeled as Cyclobenzaprine HCl Tablet, USP 5 mg.

Unintentional dosing with Cyclobenzaprine HCl may potentially lead to the development of life-threatening serotonin syndrome, which has been reported with Cyclobenzaprine HCI when used in combination with other drugs, such as selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), tramadol, bupropion, meperidine, verapamil, or MAO inhibitors. The effects of alcohol, barbiturates, and other CNS depressants may be enhanced, and may impair mental and/or physical abilities required for performance of hazardous tasks, such as operating machinery or driving a motor vehicle. Amantadine has a precaution in its prescribing indication about the abrupt discontinuation of the medicine. Missed doses of Amantadine in a few patients with Parkinson’s disease have experienced a parkinsonian crisis, i.e., a sudden marked clinical deterioration, when this medication was suddenly stopped.

BACKGROUND: Cyclobenzaprine HCl 5mg 50ct Unit Dose (NDC# 50268-190-15) is used for the relief of muscle spasms and Amantadine HCl 100mg 50ct Unit Dose (NDC# 50268-069-15) is used for the treatment of Parkinson’s and drug-induced extrapyramidal reactions and the treatment of various viral-based conditions. Both products are packaged in 50-count hospital unit dose cartons (10 unit doses per card, 5 cards per carton). The affected lot of Cyclobenzaprine and Amantadine is Lot 16710 with an expiration date of 07/2018. The subject products were fully distributed to R&S Northeast, and then further distributed nationwide.

RECOMMENDATION: Apace Packaging LLC has notified its distributors and customers by email and is arranging for return of all recalled product. Distributors that have any of the subject product which is being recalled should contact Customer Service at AvKARE, Inc. at 931-292-6222 to arrange for the return of the product.

Warfarin Sodium Tablets (Jantoven), 3mg: Recall - Mislabeled Bottles Containing Higher Dosage

Feb 21, 2011

Audience: Pharmacy, Family Practice, Consumer

[UPDATED 02/21/2011] Expansion of Recall: Affected Products Include Amantadine, Amlodipine, Androxy, Baclofen, Bethanechol, Jantoven and Oxybutynin

[Posted 02/17/2011]

ISSUE: Upsher-Smith Laboratories and FDA notified healthcare professionals of the recall of one lot of Jantoven Warfarin Sodium, USP, 3mg Tablets, an anticoagulant, after a single bottle labeled as Jantoven Warfarin Sodium, USP, 3mg Tablets was found to contain tablets at a higher 10mg strength. To date, the company has identified no additional mislabeled bottles. 

BACKGROUND: The recalled lot is numbered as #284081, with an expiration date of September 2012. The product lot was distributed to wholesalers, retail chains and independent pharmacies throughout the United States. The primary risk of substituting 10mg warfarin for 3mg warfarin is overdosing more than 3 times the labeled amount which leads to excessive anticoagulation that could be expected to result in life-threatening hemorrhage in patients.   

RECOMMENDATION: The two Jantoven tablets (see photo at link below) can be readily identified by color: the 3mg tablet is tan and the 10mg tablet is white. In addition, the 3mg tablet is imprinted with the letters WRF, a line, and the number 3 below the line. The reverse side of the 3mg tablet carries the number 832. The 10mg tablet is imprinted with the letters WRF, a line, and the number 10 below the line. The reverse side of the 10mg tablet carries the number 832. Consumers and pharmacists can call the Upsher-Smith medical information line at 1-888-650-3789 for more information and to access product details, Monday-Friday between 8:00 a.m. and 5:00 p.m. (CST).


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