The adverse reactions to Actiq are typical of any opioids. These side effects usually decrease in intensity or stop altogether with continued use at proper doses. The most serious side effect is respiratory problems potentially leading to stopped breathing, circulatory depression, dangerously low blood pressure and shock. Physicians should expect side effects and treat patients accordingly.

Actiq may cause nervous system side effects, including mental and respiratory depression, especially in the elderly. Respiratory depression is a condition where the lungs do not adequately exchange oxygen and carbon dioxide, characterized by slow or shallow breathing. Coughing may occur. Other nervous system side effects include stupor, acute confusion, extreme drowsiness and feelings of sadness. Muscle rigidity may occur, potentially aggravating respiratory depression, especially if rigidity involves the glottis, or musculature in the throat. Muscle twitching in the upper body may occur

Actiq rarely causes high blood pressure, slow or irregular heartbeats. Gastrointestinal side effects include nausea, vomiting and constipation. Dental decay is possible when consuming Actiq suckers or lozenges that contain sugar. Narcotics such as Actiq may cause urinary retention. Localized rashes are associated with Actiq patch use, especially near the area of application.

Sudden cessation of Actiq may cause withdrawal symptoms in opioid dependent people. Fast tapering may cause side effects such as abdominal cramps, agitation, anxiety, insomnia, tremor, blurred vision, restlessness, vomiting and sweating.
