You should not take duloxetine delayed-release capsules if you have uncontrolled narrow-angle glaucoma or if you are taking a Monoamine Oxidase Inhibitor (MAOI).  Tell  your healthcare provider or pharmacist if you are taking an MAOI, including the antibiotic linezolid.  You should not start duloxetine delayed-release capsules if you stopped taking an MAOI within the last 14 days, and you should not take an MAOI within 5 days of stopping duloxetine delayed-release capsules, unless directed by your physician.

Duloxetine delayed-release capsules and other antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, or young adults within the first few months of treatment or when the dose is changed.  Depression or other serious mental illnesses are the most important causes of suicidal thoughts or actions.  Watch for changes in thought or behavior and call your physician right away if you notice:

  • New or sudden changes in mood, behavior, actions, thoughts, or feelings, especially if severe.
  • Pay particular attention to such changes when duloxetine delayed-release capsules are started or when the dose is changed.

Keep all follow-up visits with your healthcare provider and call between visits if you are worried about symptoms.

Duloxetine delayed-release capsules can cause sleepiness or may affect your ability to make decisions, think clearly, or react quickly.  You should not drive, operate heavy machinery, or do other dangerous activities until you know how duloxetine delayed-release capsules affect you. Use of duloxetine delayed-release capsules concomitantly with heavy alcohol intake may be associated with severe liver injury.  Avoid heavy alcohol use while taking duloxetine delayed-release capsules.
