Vomiting oxycodone

Other side effects of oxycodone can include nausea, dizziness, vomiting, itchy skin, weakness, and headache. Oxycodone should not be given to patients... 

Hallucinations have been described after the use of morphine in various dosage forms in one series, patients experienced adequate pain relief and no further hallucinations or nightmares when changed to oxycodone (540). Delusions and hallucinations have been reported in a patient who was also taking dosulepin (541). Restlessness, vomiting, and disorientation were described in two male patients over 60 years of age taking modified-release morphine for relief of pain in advanced cancer (542). 

Oral transmucosal fentanyl citrate has two advantages it is more acceptable as a flavored lozenge than an oral elixir or tablet would be, especially in children, and 25% goes directly into the systemic circulation without first-pass metabolism (SEDA-20, 77). Its main adverse effect is dose-dependent nausea and/or vomiting, which occurs in 25-50% of patients. In a double-blind, placebo-controlled comparison of oral transmucosal fentanyl citrate (10 pg/kg) and oral oxycodone (0.2 mg/kg) in outpatient wound care procedures in 22 children, there were similar outcomes and no adverse effects in either group (40). 

PE On physical examination, her vital signs are T 37.6°C, BP 128/82 mm Hg, HR 84 beats/min, and RR 18 breaths/min. The pain is described as a chronic 9/10. Her current pain regimen includes oxycodone 10-20 mg every 4 to 6 hours as needed (prn) for pain (about 100 mg/day) and hydromorphone 0.8-1.2 mg IV every 1 to 2 hours prn for breakthrough pain (about 8 mg/day). Allergies (ALL) Morphine (itching, flushing), codeine (nausea, vomiting), meperidine (involuntary leg movements, and facial tics). 

Comparative studies Tapentadol, a centrally acting p opioid receptor agonist and a noradrenaline reuptake inhibitor, has been compared with oxycodone in the management of moderate to severe chronic osteoarthritis in 1030 patients who were randomized to tapentadol ER 100-250 mg bd, oxycodone CR 20-50 mg bd, or placebo [181. Tapentadol ER was associated with less nausea and vomiting (23% versus 41%) and constipation (19% versus 37%) than oxycodone CR. Dropouts were also more conunon with oxycodone CR (43% versus 19%), mainly because of gastrointestinal effects. Tapentadol ER was better tolerated than oxycodone CR.

Comparison studies show that oxycodone CR has an improved side-effect profile compared to morphine with less occurrence of reactions, including nausea, vomiting, primitus, and fewer hallucinations. 

Better gastrointestinal tolerability than oxycodone CR, specifically, less nausea and vomiting and constipation in the osteoarthritis and CLBP efficacy trials and 1-year safety trial [6,8,10]. 

Observational studies In patients with moderate to severe cancer pain taking OxyContin (controlled-release oxycodone hydrochloride), adverse reactions occurred in 25% in the first week and the incidence gradually fell with time, to 12% in the 8th week [132 ]. The most common adverse effects reported in the first week were constipation (26%), nausea (13%), vomiting (6.2%), dizziness (5%), and lethargy (3.7%). Other effects included dysuria, fatigue, headache, pruritus, and thirst. There was a similar pattern at 8 weeks. Five patients had delusions after dosage reduction or withdrawal, and another had delirium on days 2 and 3. The authors suggested that the adverse effects of OxyContin could be reduced with preventive medication. 

Comparative studies In 14 patients using controlled-release oxycodone for postoperative pain and nine using patient-controlled morphine, there was a lower incidence of postoperative nausea and vomiting with oxycodone (14% versus 20%) [135 ]. There was no somnolence, respiratory depression, confusion, or pruritus in either group. 

Case 2 Ms B, a 22-year-old Hispanic female, presented with 3 weeks of severe back pain and intractable nonbloody vomiting five times daily. Physical examination revealed mild diffuse abdominal tenderness. Basic laboratory studies and imaging studies were unremarkable. Ms B was given oxycodone to relieve the back pain, but she complained that opiates were not effective, and that only smoking marijuana relieved the pain.
