Serious adverse reactions associated with morphine sulfate use include: respiratory depression, apnea, and to a lesser degree, circulatory depression, respiratory arrest, shock and cardiac arrest.
The common adverse reactions seen on initiation of therapy with morphine sulfate are dose-dependent and are typical opioid-related side effects. The most frequent of these include constipation, nausea, and somnolence. Other commonly observed adverse reactions include: lightheadedness, dizziness, sedation, vomiting, and sweating. The frequency of these events depends upon several factors including clinical setting, the patient’s level of opioid tolerance, and host factors specific to the individual. Anticipate and manage these events as part of opioid analgesia therapy.
