Zohydro ER Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Zohydro ER (hydrocodone bitartrate) Extended Release is an opioid agonist used for management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Common side effects of Zohydro ER include constipation, nausea, sleepiness, fatigue, vomiting, tiredness, headache, dizziness, dry mouth, itching, abdominal pain, swelling of legs and feet, upper respiratory tract infection, muscle spasms, urinary tract infection, back pain, and tremor.
The starting dose of Zohydro ER is individualized based on the patient's prior analgesic treatment experience and risk factors for addiction, abuse, and misuse. Zohydro ER may interact with alcohol, sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, agonist/antagonist analgesics, MAO inhibitors, and anticholinergics. Tell your doctor all medications and supplements you use. Zohydro ER is not recommended for use during pregnancy as it may harm a fetus. Use during pregnancy can cause life-threatening withdrawal symptoms in a newborn baby. Zohydro ER is not recommended for use while breastfeeding. This drug passes into breast milk and may harm a nursing baby. Withdrawal symptoms may occur if you suddenly stop taking this medication.
Our Zohydro ER (hydrocodone bitartrate) Extended Release Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The safety of ZOHYDRO ER was evaluated in a total of 1,148 subjects in Phase 3 clinical trials.
Table 3 lists the most frequently occurring adverse reactions occurring at a greater frequency than placebo from the placebo-controlled trial in subjects with moderate-to-severe chronic lower back pain.
