Troxyca ER Overview

Updated: 

Troxyca ER is a prescription medication used to manage severe pain. It is formulated to deter abuse. 

Troxyca ER is a single product containing 2 medications: oxycodone and naltrexone.

Oxycodone belongs to a group of drugs called opioids. Opioids block the pain signal from reaching the brain, which helps to reduce the perception of pain. Naltrexone belongs to a group of drugs called opiate antagonists. It works by blocking the effects of opioid medications.

This medication comes in capsule form and is to be taken by mouth. The dosing is selected by a prescriber trained in pain management and depends on the severity of pain, response, prior pain management therapies, and risk factors for addiction, abuse, and misuse. The lowest effective dose should be given for the shortest possible duration. 

Swallow capsule whole; do not crush, chew, or dissolve the pellets in capsule.

Common side effects of Troxyca ER include nausea, constipation, vomiting and headache.

Troxyca ER can also cause drowsiness. Do not drive or operate heavy machinery until you know how Troxyca ER affects you.
