The company estimates about 1,100 bottles out of 276,000 distributed units of of oral drug Temodar and its generic temozolomide were put on the market with a faulty child-resistant closure. It said consumers who find broken packaging should contact Merck for a replacement cap. Patients can continue to take the drugs.
The capsules were distributed in 5- and 14-count brown glass bottles with white plastic tops since July 2013. No injuries have been reported so far.
Merck & Co. markets Temodar itself but makes temozolomide on behalf of Sandoz.
