A popular anxiety drug taken by nearly 2million Americans is being recalled nationwide over a 'life-threatening' packaging error.
Sixteen lots of the anti-anxiety drug clonazepam, sold under the brand name Par Pharmaceutical, are being recalled because they were printed with the wrong dosage strength on the label.
The recall, issued by the manufacturer Endo Inc., affects 0.125 milligrams (mg), 0.25mg, 1mg and 2mg prescriptions of clonazepam orally disintegrating tablets.
The incorrect dosing strength is printed on the carton the drugs are sold in, with the correct dose printed on the blister strips and tablets inside.
Endo has warned patients to stop taking the recalled products immediately, saying there was a 'reasonable probability' they could suffer 'life-threatening respiratory depression,' when breathing becomes dangerously slow.
Patients on the maximum dosage of clonazepam (2mg), those with pulmonary disease or who take other drugs that can cause respiratory depression are said to be most at risk.
Pennsylvania-based Endo has blamed an unnamed 'third-party packager' for the error.
There have been no reports of serious adverse events as a result of the error, the company said.

This is just the latest drug recall to hit the US, after 300,000 medications for kidney conditions were recalled last week over fears they could be contaminated with a cancer-causing ingredient, and antidepressants were recalled last month over fears they contained a chemical used in rocket fuel.
Patients who have the drug are being urged to throw it away immediately and to contact their pharmacy for a replacement.
Those who have ingested the recalled pills should contact their doctor immediately.
A total of 16 lots of the medication have been recalled, with each package containing 60 tablets packed in 10 blister strips each containing six pills.
It is not clear how many packages were are in a single lot.
Patients are being urged to check their medication's lot number, found printed on the blister strips, to find out whether their dose is recalled.

In its voluntary recall, also published by the FDA, the manufacturer said: 'Children and adults who inadvertently consume a higher dose of Clonazepam could be at increased risk for the adverse events of significant sedation, confusion, dizziness, diminished reflexes, ataxia and hypotonia.'

Ataxia is loss of muscle coordination, leading to clumsy movements, and hypotonia is decreased muscle resistance to movement, making them appear floppy.
The manufacturer added: 'There is reasonable probability for significant, possibly life-threatening, respiratory distress.
'[This is] especially for patients with concomitant pulmonary disease, patients who have prescribed dosing near maximal dosing and patients also taking other medications that could cause additional respiratory distress.'
Clonazepam is commonly prescribed to treat seizures, epilepsy and panic disorders, a type of anxiety.
It works by raising levels of gamma-aminobutyric acid (GABA) in the brain, which helps to calm the nerve system and cause muscles to relax.
There are more than 23million prescriptions of the medication written in the US every year.
