An attempt by a patient to overcome any naltrexone opioid blockade by administering large amounts of exogenous opioids is especially dangerous and may lead to a fatal overdose or life-threatening opioid intoxication (e.g., respiratory arrest, circulatory collapse).

In patients requiring intermittent opiate treatment, CONTRAVE therapy should be temporarily discontinued and lower doses of opioids may be needed.

Interactions with Drugs Affecting Cytochrome P450 Isoenzymes The effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with codeine are complex.

Use of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with acetaminophen and codeine phosphate tablets requires careful consideration of the effects on the parent drug, codeine, and the active metabolite, morphine ( see WARNINGS and PRECAUTIONS, Drug Interactions ).

Consider recommending or prescribing an opioid overdose reversal agent ( see WARNINGS, Life-Threatening Respiratory Depression ; DOSAGE AND ADMINISTRATION, Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose ).

If concomitant use is warranted, consider recommending or prescribing an opioid overdose reversal agent ( see WARNINGS, Life-Threatening Respiratory Depression ; DOSAGE AND ADMINISTRATION , Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose ).

Patient Access to an Opioid Overdose Reversal Agent for the Emergency Treatment of Opioid Overdose Inform patients and caregivers about opioid overdose reversal agents (e.g., naloxone, nalmefene).
