Our health plan dr wrote prescription for Lyrica 50 mg for my husband and now the HMO said will not cover cost of this prescription until my husband goes on a trial of 30 days trying 2 alternative prescriptions (ea thirty days ) My husband cant take gabapentin, as he cannot work on this med ication-puts him to sleep.. he was on Lyrica up to 75 mg 2x day w a previous health plan the drugs that our current HMO wants him to do on a trial for 30 days are: Cymbalta or Amitriptyline (Elevil) what side effects do these drugs have. He has burning bottom feets, has spinal stenous, ureter-left kidney has stones, etc...been on tramadol for long time (years) and seems to overmedicate when he has control of opiod prescriptions... no more than 6 in 24 hr period and he has taken more than that, if he has control of his meds.
