Medication Guide
ZOHYDRO® ER (zoh-hye-droh)
(hydrocodone bitartrate) extended-release capsules, CII

ZOHYDRO ER is:

  • A strong prescription pain medicine that contains an opioid (narcotic) that is used to treat pain severe enough to require daily, around-the-clock, long-term treatment with an opioid, when other pain treatments such as non-opioid pain medicines or immediate-release opioid medicines do not treat your pain well enough or you cannot tolerate them.
  • A long acting (extended-release) opioid pain medicine that can put you at risk for overdose and death. Even if you take your dose correctly as prescribed, you are at risk for opioid addiction, abuse, and misuse that can lead to death.
  • Not for use to treat pain that is not around-the-clock.

Important information about ZOHYDRO ER:

  • Get emergency help right away if you take too much ZOHYDRO ER (overdose). When you first start taking ZOHYDRO ER, when your dose is changed, or if you take too much (overdose), serious or life-threatening breathing problems that can lead to death may occur.
  • Never give anyone else your ZOHYDRO ER. They could die from taking it. Store ZOHYDRO ER away from children and in a safe place to prevent stealing or abuse. Selling or giving away ZOHYDRO ER is against the law.
 Do not take ZOHYDRO ER if you have:
  • severe asthma, trouble breathing, or other lung problems.
  • a bowel blockage or narrowing of the stomach or intestines.

• head injury, seizures    • liver, kidney, thyroid problems
• problems urinating       • pancreas or gallbladder problems
• abuse of street or prescription drugs, alcohol addiction, or mental health problems.
Tell your healthcare provider if you are:
  • pregnant or planning to become pregnant. Prolonged use of ZOHYDRO ER during pregnancy can cause withdrawal symptoms in your newborn baby that could be life-threatening if not recognized and treated.
  • breastfeeding. ZOHYDRO ER passes into breast milk and may harm your baby.
  • Taking prescription or over-the-counter medicines, vitamins, or herbal supplements. Taking ZOHYDRO ER with certain other medicines can cause serious side effects that could lead to death.

  • Swallow ZOHYDRO ER whole. Do not cut, break, chew, crush, dissolve, snort, or inject ZOHYDRO ER because this may cause you to overdose and die.

Call your healthcare provider if the dose you are taking does not control your pain. 

  • Do not stop taking ZOHYDRO ER without talking to your healthcare provider
