I am restarting procedures that require I take a valium one hour before. This time the medicine did not work and when the procedure started, I had a series of muscle spasms;the opposite of prior out-patient surgeries.Same dr., same medicine.After recovery,I called the pharmacy where meds were filled.No one wants to talk to me,but I was given the Rx makers name. I am scared to have my other two procedures if no one will check this medicine. I need some answers.
