Ultram and Ultram ER may interact with other medicines. It is extremely important for you to tell your doctor about all the medicines you are currently taking, including your over-the-counter (non-prescription) medicines. The migraine journal can help you keep a list of all of your medicines so that any possible drug interactions can be evaluated. Do not stop taking any medicine without telling your doctor.

Inhibitors of liver enzymes CYP2D6 (such as quinidine, fluoxetine, paroxetine and amitriptyline) and CYP3A4 (ketoconazole and erythromycin), may prevent Ultram from being eliminated from your body and can increase your risk of serious side effects including seizures and serotonin syndrome.

Ultram/Ultram ER Drug Interactions With Carbamazepine
Taking carbamazepine (an epilepsy and bipolar disorder medicine)along with Ultrammay significantly reduce the pain relieving effectiveness of Ultram. Because carbamazepine causes Ultram to be absorbed into your body faster than normal and because of the increased risk of seizure, Ultram and carbamazepine should not be taken together.
