How to use
Use Cymbalta as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Swallow Cymbalta whole. Do not break, crush, or chew before swallowing. Do not open the capsule and sprinkle the contents on food or in liquid.

Continue to take Cymbalta even if you feel well. Do not miss any doses.
Drug Class and Mechanism
Cymbalta is a serotonin and norepinephrine reuptake inhibitor (SNRI). It works by restoring the balance of certain natural substances in the brain (serotonin and norepinephrine), which helps to improve certain mood problems.
If you miss a dose of Cymbalta, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Store Cymbalta at 77 degrees F (25 degrees C). Brief storage between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Cymbalta out of the reach of children and away from pets.
Do not use Cymbalta if:
you are allergic to any ingredient in Cymbalta;
you have uncontrolled narrow-angle glaucoma;
you have liver problems or severe kidney problems, or are having dialysis;
you are taking or have taken a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days;
you are taking a quinolone antibiotic (e.g., ciprofloxacin), a selective serotonin reuptake inhibitor (SSRI) (e.g., fluoxetine, fluvoxamine), a SNRI (e.g., venlafaxine), thioridazine, or tryptophan.
