side effects of<unk>  Two tablets (10 mg) of<unk>  and safety blisters Most common side effects of<unk>  include reduced sensitivity to pain, delayed gastric emptying, euphoria, anxiolysis, feelings of relaxation, and respiratory depression. Common side effects of<unk>  include constipation (23%), nausea (23%), vomiting (12%), somnolence (23%), dizziness (13%), itching (13%), dry mouth (6%), and sweating (5%). Less common side effects (experienced by less than 5% of patients) include loss of appetite, nervousness, abdominal pain, diarrhea, urinary retention, dyspnea, and hiccups. Most side effects generally become less intense over time, although issues related to constipation are likely to continue for the duration of use.<unk>  in combination with naloxone in managed-release tablets, has been formulated to both deter abuse and reduce "opioid-induced constipation". Dependence and withdrawal The risk of experiencing severe withdrawal symptoms is high if a patient has become physically dependent and discontinues<unk>  abruptly. Medically, when the drug has been taken regularly over an extended period, it is withdrawn gradually rather than abruptly. People who regularly use<unk>  recreationally or at higher than prescribed doses are at even higher risk of severe withdrawal symptoms. The symptoms of<unk>  withdrawal, as with other opioids, may include "anxiety, panic attack, nausea, insomnia, muscle pain, muscle weakness, fevers, and other flu-like symptoms". Withdrawal symptoms have also been reported in newborns whose mothers had been either injecting or orally taking<unk>  during pregnancy. Hormone levels As with other opioids, chronic use of<unk>  (particularly with higher doses) often causes concurrent hypogonadism (low sex hormone levels).
