subject: Getting Rid of Mild Pain Using a Generic Darvocet [print this page] Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Darvocet-N. Make sure your doctor knows if you are taking tranquilizers, sleep aids, antidepressants, antihistamines, or any other drug that make you sleepy. The use of these drugs with propoxyphene increases their sedative effects and may lead to overdose symptoms, including death. Also, talk to your doctor about your complete medical history, especially if you have kidney or liver problems, if you use alcohol in excess, or if you are suicidal or addiction prone.
