    Major (for nerve pain (neuralgia))
  • Side effects
    None
  • Adherence
    Always
  • Burden
    Not at all hard to take
Dosage: 50 mg Daily
Advice & Tips: 50 mg is for everyone but can go to 100 but usually no difference at all.. I was on effexor and then cynbalta both which didn't work out for me and then this one did.. all 3 are serotonin and norepinephrine reuptake inhibitor (SNRI) antidepressant. ... It increases serotonin and norepinephrine activity in the brain, which regulates mood.
Cost: < $25 monthly
