Revia Overdose, Contraindications and Information - Naltrexone
Revia Overdose, Contraindications and Information - Naltrexone
OVERDOSE
There is limited clinical experience with REVIA overdosage in humans. In one
study, subjects who received 800 mg daily REVIA for up to one week showed no
evidence of toxicity.
In the mouse, rat and guinea pig, the oral LD50s were 1,100-1,550 mg/kg; 1,450
mg/kg; and 1,490 mg/kg; respectively. High doses of REVIA (generally ≥1,000
mg/kg) produced salivation, depression/reduced activity, tremors, and convulsions.
Mortalities in animals due to high-dose REVIA administration usually were due
to clonic-tonic convulsions and/or respiratory failure.
Treatment Of Overdosage: In view of the lack of actual
experience in the treatment of REVIA overdose, patients should be treated symptomatically
in a closely supervised environment. Physicians should contact a poison control
center for the most up-to-date information.
CONTRAINDICATIONS
REVIA is contraindicated in:
- Patients receiving opioid analgesics.
- Patients currently dependent on opioids.
- Patients in acute opioid withdrawal (see WARNINGS).
- Any individual who has failed the naloxone challenge test or who has a positive
urine screen for opioids.
- Any individual with a history of sensitivity to REVIA or any other components
of this product. It is not known if there is any cross-sensitivity with naloxone
or the phenanthrene containing opioids.
- Any individual with acute hepatitis or liver failure.
