In March 2011, Pfizer Inc voluntarily recalled from US wholesalers and retailers all dosage forms of EMBEDA® (morphine sulfate and naltrexone hydrochloride) Extended Release Capsules CII because a prespecified requirement was not met during routine testing.

On November 4, 2013, the U.S. Food and Drug Administration (FDA) approved a Prior Approval Supplement for EMBEDA that included an update to the EMBEDA manufacturing process addressing the prespecified stability requirements.

Pfizer anticipates product availability in the second quarter of 2014.

What is EMBEDA?

EMBEDA is a strong prescription pain medicine that contains an opioid (narcotic) that is used to treat moderate to severe around-the-clock pain.

While taking EMBEDA, do not drive or operate heavy machinery until you know how EMBEDA affects you. EMBEDA can make you sleepy, dizzy, or lightheaded.

Do not drink alcohol or use prescription or over-the-counter medicines that contain alcohol as these can increase the risk of breathing problems when taking EMBEDA. Tell your healthcare provider about other prescription medicines you are taking as certain medicines can also increase the risk of breathing problems.

The possible side effects of EMBEDA are constipation, nausea, sleepiness, vomiting, tiredness, headache, dizziness, abdominal pain. Call your healthcare provider if you have any of these symptoms and they are severe.
