Side Effects and Interactions

Other side effects to be aware of include headache, euphoria, abdominal pain, sweating and constipation.

Some people experience shortness of breath, especially if they have asthma.

Other less common reactions include skin rash, disorientation, dry mouth, visual problems and urinary difficulties. Report any such symptoms to your physician promptly.

Long-term use of Darvocet-N 100 has drawbacks. Like any narcotic, it may be habit forming if you take it regularly.

Do not increase the dose on your own in a quest to achieve greater pain relief. But don't play the hero by skipping doses during an acute crisis.

Pain is more easily managed if it can be nipped in the bud instead of trying to play catch up when it has gotten out of control.

Acetaminophen and propoxyphene may both cause liver problems in large doses or over long periods, so liver function should be monitored.

As kidney damage is also a potential risk, your physician should evaluate your need for this combination pain reliever periodically.

If you are taking any other medicines, check with a physician or pharmacist.

Alcohol as well as certain over-the-counter and prescription drugs can add to the sedative effect of this analgesic.

Antihistamines, antianxiety agents, antidepressants and sleeping pills can all cause drowsiness and might make this effect worse.

An anticonvulsant like Dilantin (phenytoin) could increase the risk of liver trouble for patients on Darvocet-N 100.
