HI, My husband was prescribed Gabapentin 300 mg last June but for some reason, we don t remember, stopped this medication. It was prescribed for Essential Tremor. He now takes Propranolol ER 120 mg for Essential Tremor and as a Beta Blocker due to a heart attack he had in 2012. He recently had decompression surgery of the nerve root in L4/L5. His right foot has been numb since September and his brother suggested Gabapentin for the nerve pain he continues to have in his foot. We are wondering about how it will interact with other drugs he takes and if he would have to stop the Propranolhol? He takes 75 mg. Plavix, 2.5 mg Lisinopril 2 times a day,10 mg Singular,5 mg. Finasteride,40 mg. Atorvastatin,81 mg aspirin,150 mg Zyertec,1200 mg Fish Oil X 2,100 mg. Co Q 10,Does Gabapentin intefear with any of his other meds?
