PRECAUTIONS

Tolerance and Physical Dependence

Tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (in the absence of disease progression or other external factors). Physical dependence is manifested by withdrawal symptoms after abrupt discontinuation of a drug or upon administration of an antagonist. Physical dependence and tolerance are not unusual during chronic opioid therapy. Buy darvocet online

The opioid abstinence or withdrawal syndrome is characterized by some or all of the following: restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis. Other symptoms also may develop, including: irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate. In general, opioids should not be abruptly discontinued. If Darvocet-N (propoxyphene napsylate and acetaminophen) is abruptly discontinued in a physically dependent patient, an abstinence syndrome may occur. If signs and symptoms of withdrawal occur, patients should be treated by reinstitution of opioid therapy followed by gradual tapered dose reduction of Darvocet-N (propoxyphene napsylate and acetaminophen) combined with symptomatic support. Use in Pancreatic/Biliary Tract Disease

Darvocet-N (propoxyphene napsylate and acetaminophen) may cause spasm of the sphincter of Oddi and should be used with caution in patients with biliary tract disease, including acute pancreatitis. Opioids like Darvocet-N (propoxyphene napsylate and acetaminophen) may cause increases in the serum amylase level. Buy darvocet online
