As of April 2014, Paladin Labs Inc. stopped printing tablet markings (“LP 100”, “LP200” and “LP 300”) on the associated strengths of Tridural ® (tramadol HCl extended release tablets). There was no change to the formulation and there is no quality issue with the product. For a period of time, there may be marked and unmarked tablets on the market. In order to avoid any potential confusion to the pharmacist or patient, the company will be reinstating markings on the tablets starting with the next manufactured lots.
