3. Significant weight loss or weight gain
4. Insomnia or hypersomnia
5. Psychomotor agitation or retardation
6. Fatigue or loss of energy
7. Feelings of worthlessness or excessive or inappropriate guilt
8. Diminished ability to think or concentrate or indecisiveness
9. Recurrent thoughts of death or suicide
Five (or more) symptoms have been present during the same 2-week period and represent a change from previous
functioning; at least one of the symptoms is either (1) depressed mood or (2) loss of interest or pleasure.

mood
- Loss of interest or

behaviour

Milnacipran's Efficacy in Major Depression
Efficacy vs Venlafaxine
Venlafaxine
=> SSRI at low doses, SNRI only at higher doses (> 150 mg/day)
=> requires dose-titration to bring in NA activity
and true SNRI dose less well tolerated than SSRIs
Milnacipran
=> SNRI at all doses
(well balanced reuptake inhibition of 5-HT and NA whatever the dose)
=> no dose-titration required for NA activity
and all doses as well tolerated as SSRIs

How to prescribe
How to prescribe milnacipran
Dosing schedule
 It is advisable to start with a low dose of 25 mg twice daily or 50 mg
once daily of milnacipran
 The dose should then be progressively increased to 100 mg/day
Recommended (optimum) dosage :
100 mg a day in two 50 mg doses, 1 capsule morning and evening
 Doses up to 200 mg/day can be safely given where further efficacy is
required
 Milnacipran can be taken with food
(food does not modify the pharmacokinetics of milnacipran ; nevertheless, less nausea is observed when
administered with food, and it is recommended that milnacipran be taken during meals)
