My husband has prostate cancer which has spread to the bone, He has been on hormone therapy for over a year. He also has trigeminal jaw pain also and has started a med along with gabapentin to reduce the severity of the pain in his jaw. Both meds act as an anti seizure med. The new med is lamoTRIgine 100mg. I was wondering if these drugs would interfere with the hormone meds my husband is taking. His PSA level has went from in the 30 s to over 100 in just a few months. His Oncologist has started him on Chemo.
