hi,
I found this on the net. Best of luck to you!!
Some MEDICINES MAY INTERACT with Darvocet-N 100. Tell your health care provider if you are taking any other medicines, especially any of the following:
Anticoagulants (eg, warfarin) because the risk of bleeding may be increased
Cimetidine, HIV protease inhibitors (eg, ritonavir), or isoniazid because they may increase the risk of Darvocet-N 100's side effects
Naltrexone because it may decrease Darvocet-N 100's effectiveness and may cause withdrawal symptoms
Anticonvulsants (eg, carbamazepine), antidepressants (eg, amitriptyline, fluoxetine), barbiturate anesthetics (eg, thiopental), or sodium oxybate (GHB) because the risk of their side effects may be increased by Darvocet-N 100
Medicines that may harm the liver (eg, methotrexate, ketoconazole) because the risk of liver side effects may be increased. Ask your doctor if you are unsure if any of your medicines might harm the liver.
If you take enough of the darvoset you're probably not going to withdraw at all. You're just substituting one opiate for another.
