What should I watch for while taking duloxetine?

Visit your prescriber or health care professional for regular checks on your progress. You may have to take duloxetine for 4 weeks before you feel better. If you have been taking duloxetine for some time, do not suddenly stop taking it. You must gradually reduce the dose to avoid side effects. Ask your prescriber or health care professional for advice.

Duloxetine may cause an increase in blood pressure. Check with your prescriber or health care professional; you may be able to measure your own blood pressure and pulse. Find out what your blood pressure and heart rate should be and when you should contact him or her.

You may get drowsy, dizzy or have blurred vision. Do not drive, use machinery, or do anything that needs mental alertness until you know how duloxetine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may increase dizziness or drowsiness; avoid alcoholic drinks.

Duloxetine can make your mouth dry. Chewing sugarless gum, sucking hard candy and drinking plenty of water will help.

Do not treat yourself for coughs, colds, or allergies without asking your prescriber or health care professional for advice. Some ingredients may increase possible side effects.

If you are going to have surgery, tell your prescriber or health care professional that you are taking duloxetine.

Where can I keep my medicine?

Keep out of the reach of children in a container that small children cannot open.

Store at room temperature between 20 degrees and 25 °C (68 degrees and 77 °F), in a dry place. Throw away any unused medicine after the expiration date.
