What is hydrocodone?
Zohydro ER (hydrocodone) is an opioid pain medication.
Zohydro ER is an extended-release capsule used for around-the-clock treatment of severe pain.
Zohydro ER capsule are not for use on an as-needed basis for pain.
Hydrocodone can slow or stop your breathing. Never use Zohydro ER in larger amounts, or for longer than prescribed. Do not crush, break, or open an extended-release pill. Swallow it whole to avoid exposure to a potentially fatal dose.
Hydrocodone may be habit-forming, even at regular doses. Never share Zohydro ER with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep Zohydro ERin a place where others cannot get to it.
Tell your doctor if you are pregnant. Hydrocodone may cause life-threatening withdrawal symptoms in a newborn if the mother has taken this medicine during pregnancy.
Fatal side effects can occur if you use Zohydro ER with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not use Zohydro ER if you are allergic to hydrocodone, or if you have:
severe asthma or breathing problems; or
a blockage in your stomach or intestines.
To make sure Zohydro ER is safe for you, tell your doctor if you have ever had:
breathing problems, sleep apnea;
drug or alcohol addiction, or mental illness;
liver or kidney disease;
problems with your gallbladder, pancreas, or thyroid; or
a heart rhythm disorder called long QT syndrome.
If you use Zohydro ER while you are pregnant, your baby could become dependent on hydrocodone. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on opioids may need medical treatment for several weeks.
Ask a doctor before using Zohydro ER if you are breastfeeding. Tell your doctor if you notice severe drowsiness or slow breathing in the nursing baby.
How should I take Zohydro ER?
Zohydro ER may be habit-forming, even at regular doses. Follow the directions on your prescription label and read all medication guides. Never use hydrocodone in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of this medicine.
Never share Zohydro ER with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep Zohydro ER in a place where others cannot get to it. Selling or giving away opioid medicine is against the law.
Your dose needs may be different if you have recently used a similar opioid pain medicine and your body is tolerant to it. Talk with your doctor if you are not sure you are opioid-tolerant.
Do not crush, break, or open an extended-release Zohydro ER capsule. Swallow the capsule whole to avoid exposure to a potentially fatal dose. Never crush or break a capsule to inhale the powder or mix it into a liquid to inject the drug into your vein. This can cause death.
Do not stop using this medicine suddenly after long-term use, or you could have serious withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
Store at room temperature, away from heat, moisture, and light. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.
Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.
Usual Adult Dose for Chronic Pain:
The following dosing recommendations can only be considered suggested approaches to what is actually a series of clinical decisions over time; each patient should be managed individually.
As First Opioid Analgesic and For Patients who are NOT Opioid Tolerant:
Extended-Release Zohydro ER Capsules: Initial dose: 10 mg orally every 12 hours
-Use of higher starting doses in patients who are not opioid tolerant may cause fatal respiratory depression; monitor patients closely for respiratory depression, especially during the first 24 to 72 hours.
-An opioid tolerant patient is one who has been receiving for 1-week or longer at least: oral morphine 60 mg/day, fentanyl transdermal patch 25 mcg per hour, oral oxycodone 30 mg/day, oral hydromorphone 8 mg/day, oral oxymorphone 25 mg/day, or an equianalgesic dose of another opioid.
What happens if I miss a dose?
Since Zohydro ER is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next dose. Do not use two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A hydrocodone overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include severe drowsiness, pinpoint pupils, slow breathing, or no breathing.
Your doctor may recommend you get naloxone (a medicine to reverse an opioid overdose) and keep it with you at all times. A person caring for you can give the naloxone if you stop breathing or don't wake up. Your caregiver must still get emergency medical help and may need to perform CPR (cardiopulmonary resuscitation) on you while waiting for help to arrive.
Anyone can buy naloxone from a pharmacy or local health department. Make sure any person caring for you knows where you keep naloxone and how to use it.
What to avoid
Do not drink alcohol. Dangerous side effects or death could occur.
Avoid driving or hazardous activity until you know how hydrocodone will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries.
Zohydro ER side effects
Get emergency medical help if you have signs of an allergic reaction to Zohydro ER: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
