Duloxetine is used to treat depression. Duloxetine is in a class of medications called selective serotonin and norepinephrine reuptake inhibitors (SSNRIs).

Directions

Duloxetine is usually taken once or twice a day with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take duloxetine exactly as directed. Do not take more or less of it, take it more often, or take it for a longer time than prescribed by your doctor.

Precautions

It is important that your doctor check your progress at regular visits, to allow for changes in your dose and to help reduce any side effects.

Duloxetine has not been shown to add to the effects of alcohol. However, use of alcohol is not recommended in patients who are taking duloxetine.

Duloxetine may cause some people to be agitated, irritable or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you or your caregiver notice any of these adverse effects, tell your doctor right away.

This medicine can cause serious liver problems. If you experience symptoms such as dark urine, general tiredness and weakness, light-colored stools, nausea and vomiting, upper right abdominal pain, or yellow eyes and skin, contact your doctor immediately.

Four weeks of duloxetine may be required before your symptoms improve. It is important to continue duloxetine after symptoms of depression are relieved.

Do not suddenly stop taking your duloxetine. If you have been instructed to stop taking duloxetine, ask your healthcare professional how to slowly decrease the dose. This is to decrease the chance of having discontinuation symptoms such as dizziness, nausea, headache, vomiting, irritability, nightmares, prickling or tingling feelings.

Do not take duloxetine if you have taken a monoamine oxidase (MAO) inhibitor (furazolidone, phenelzine, procarbazine, selegiline, tranylcypromine) in the past 2 weeks. Do not start taking an MAO inhibitor within 5 days of stopping duloxetine. If you do, you may develop confusion, agitation, restlessness, stomach or intestinal symptoms, sudden high body temperature, extremely high blood pressure, severe convulsions, or the serotonin syndrome.
