If you notice other effects not listed above, contact your doctor or pharmacist.

DARVOCET: To prevent upset stomach, take with food or milk. Pain medications work best in preventing pain before it occurs. Once the pain becomes intense, the medication is not as effective in relieving it. Use DARVOCET exactly as directed by your doctor. Do not increase your dose, use it more frequently or use it for a longer period of time than prescribed because DARVOCET can be habit-forming. Also, if used for an extended period, do not suddenly stop using DARVOCET without your doctor's approval. Over time, DARVOCET may not work as well. Consult your doctor if DARVOCET is not relieving the pain sufficiently.

Propoxyphene should be used with extreme caution, if at all, in people who use alcohol; have a history of substance abuse or emotional conditions; or who already take drowsiness-causing drugs (e.g., antidepressants, barbiturates, muscle relaxants, pain relievers, sedatives). Fatalities have occurred in such patients when propoxyphene was misused. Patients must not take more propoxyphene than prescribed.

Tell your doctor your medical history, especially of: kidney or liver disease, breathing problems, alcohol and/or drug use, colitis or other intestinal/stomach problems, severe diarrhea, head injury, heart problems, drug allergies. Use caution when engaging in activities requiring alertness such as driving. Limit alcohol intake because it may add to the dizziness/drowsiness effects of DARVOCET. Acetaminophen may cause liver damage. Daily use of alcohol, especially when combined with acetaminophen, may increase your risk for liver damage. Check with your doctor or pharmacist for more information. DARVOCET should be used during pregnancy only when clearly needed. Discuss the risks and benefits with your doctor. Darvocet is secreted into breast milk. Though to date, no problems have been noted in nursing infants, consult your doctor before breast-feeding.

Tell your doctor of all the medicines you may use both prescription and nonprescription, especially of: carbamazepine, cimetidine, ritonavir, other narcotic pain medications, sedatives, tranquilizers, drugs used for anxiety or depression. Before taking over-the-counter pain relievers or cold, cough and allergy products, read their labels to be sure they do not also contain acetaminophen. DARVOCET contains acetaminophen and too much acetaminophen can be harmful. Do not start or stop any medicine without doctor or pharmacist approval.

If overdose is suspected, contact your local poison control center or emergency room immediately. Symptoms of overdose may include unusual sleepiness; slow, shallow breathing; cold, clammy skin; seizures; nausea; vomiting; stomach pain; and loss of consciousness.

Do not share DARVOCET with others.

If you miss a dose, take as soon as remembered; do not take if it is almost time for the next dose, instead, skip the missed dose and resume your usual dosing schedule. Do not "double-up" the dose to catch up.

Store at room temperature away from sunlight and moisture.
