You should not use duloxetine if you are allergic to it.

These medicines may interact with duloxetine and cause a serious condition called serotonin syndrome.
Duloxetine is not approved for use by anyone younger than 7 years old.
Tell your doctor if you have ever had:
heart problems, high blood pressure;
liver or kidney disease;
slow digestion;
a seizure;
bleeding problems;
narrow-angle glaucoma;
bipolar disorder (manic depression);
drug addiction or suicidal thoughts; or
if you drink large amounts of alcohol.
Some young people have thoughts about suicide when first taking an antidepressant. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.
Ask your doctor about taking duloxetine if you are pregnant. Taking this medicine during late pregnancy may cause excessive bleeding during childbirth, or serious medical complications in the baby. However, if not treated during pregnancy, conditions such as depression or fibromyalgia may cause complications in the baby or the mother.
Tell your doctor right away if you become pregnant while taking duloxetine. Do not start or stop taking this medicine without your doctor's advice. Your name may be listed on a pregnancy registry to track the effects of duloxetine on the baby.
If you are breastfeeding, tell your doctor if you notice drowsiness, feeding problems, and slow weight gain in the nursing baby.
