Avinza Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Avinza (morphine sulfate) is used to treat moderate to severe pain. Short-acting morphine is taken as needed for pain. Extended-release morphine is for use when around-the-clock pain relief is needed. It is in a group of drugs called narcotic pain relievers. Common side effects include nausea, vomiting, constipation, lightheadedness, dizziness, or drowsiness.
The dose of Avinza is individualized for each patient, depending on the patient's medical condition and other factors. Avinza may interact with MAO inhibitors, other narcotic pain medications, sedatives, tranquilizers, muscle relaxers, alcohol, other medicines that can make you sleepy or slow your breathing, pentazocine, nalbuphine, butorphanol, or buprenorphine. Tell your doctor all medications you are taking. During pregnancy, Avinza should be used only when prescribed. Using it near the expected delivery date is not recommended because of the potential for harm to a fetus. Babies born to mothers who have used this medication for an extended time may have withdrawal symptoms such as irritability, abnormal/persistent crying, vomiting, or diarrhea. If you notice any of these symptoms in your newborn, tell the doctor. This drug passes into breast milk and may rarely have undesirable effects on a nursing infant. Tell the doctor if your baby develops unusual sleepiness, difficulty feeding, or trouble breathing. Consult your doctor before breast-feeding. Do not stop taking Avinza (morphine) suddenly, or you could have withdrawal symptoms.

Clinical Studies 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In controlled and open-label clinical studies, 560 patients with chronic malignant or non-malignant pain were treated with AVINZA. The most common serious adverse events reported with administration of AVINZA were vomiting, nausea, death, dehydration, dyspnea, and sepsis. (Deaths occurred in patients treated for pain due to underlying malignancy.) Serious adverse events caused by morphine include respiratory depression, apnea, and to a lesser degree, circulatory depression, respiratory arrest, shock and cardiac arrest.
The most common adverse events (seen in greater than 10%) reported by patients treated with AVINZA during the clinical trials at least once during therapy were constipation, nausea, somnolence, vomiting, and headache. Adverse events occurring in 5-10% of study patients were peripheral edema, diarrhea, abdominal pain, infection, urinary tract infection, accidental injury, flu syndrome, back pain, rash, sweating, fever, insomnia, depression, paresthesia, anorexia, dry mouth, asthenia and dyspnea. Other less common side effects expected from opioid analgesics, including morphine, or seen in fewer than 5% of patients taking AVINZA in the clinical trials were:
Body as a Whole: malaise, withdrawal syndrome.
Metabolic and Nutritional Disorders: edema, weight loss.
Musculoskeletal: skeletal muscle rigidity.
Nervous System: abnormal dreams, abnormal gait, agitation, amnesia, anxiety, ataxia, confusion, convulsions, coma, delirium, euphoria, hallucinations, lethargy, nervousness, abnormal thinking, tremor, vasodilation, vertigo.
Respiratory System: hiccup, hypoventilation, voice alteration.
Skin and Appendages: dry skin, urticaria.
Special Senses: amblyopia, eye pain, taste perversion.
