Duloxetine is categorized as an antidepressant known as a selective serotonin and norepinephrine reuptake inhibitor (SSNRI). It functions by influencing the balance of certain chemicals in the brain, particularly in individuals experiencing depression.
This medication is prescribed for the treatment of major depressive disorder in adults. Additionally, it is utilized to address general anxiety disorder in both adults and children aged 7 and above.
Duloxetine is also employed in adults for alleviating nerve pain associated with diabetes (diabetic neuropathy) or persistent muscle or joint pain, such as low back pain and osteoarthritis pain.
Certain brands of duloxetine are specifically designated for managing fibromyalgia, a chronic pain disorder. Drizalma is designed for the treatment of fibromyalgia exclusively in adults, while Cymbalta may be administered for fibromyalgia in both adults and children aged 13 and older.
Warnings
Avoid taking duloxetine within 5 days before or 14 days after using an MAO inhibitor, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, tranylcypromine, and others, as it may lead to a potentially dangerous drug interaction.
Individuals experiencing depression or mental illness might encounter thoughts of suicide. In some cases, young people may experience an increase in suicidal thoughts when initiating treatment with an antidepressant. It is crucial to promptly inform your doctor if you undergo any abrupt changes in mood or behavior or if you have thoughts about suicide.
It is important not to discontinue the use of duloxetine without consulting your doctor first.
How should I take duloxetine?
Adhere to your doctor's prescription when taking duloxetine. Follow all instructions on your prescription label and carefully read all medication guides or instruction sheets provided. Your doctor may adjust your dose from time to time.
Taking duloxetine in higher doses or more frequently than prescribed will not enhance its effectiveness and may increase the likelihood of experiencing side effects.
Consume the capsule whole; do not crush, chew, break, or open it.
Duloxetine can be taken with or without food.
Regular monitoring of your blood pressure is necessary.
Inform your doctor of any changes in sexual function, such as a diminished interest in sex, difficulty achieving orgasm, or, for men, challenges with erections or ejaculation. Some sexual issues can be addressed.
It may take up to 4 weeks before you notice an improvement in your symptoms.
Do not discontinue the use of duloxetine abruptly, as doing so may result in unpleasant symptoms like agitation, confusion, or sensations of tingling or electric shocks. Always consult your doctor before discontinuing the medication.
Store the medication at room temperature, away from moisture and heat.

What should I avoid while taking duloxetine?
Before taking a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin, ibuprofen, naproxen, Advil, Aleve, Motrin, or others, consult your doctor. Combining an NSAID with duloxetine may increase the risk of bruising or bleeding.
Exercise caution in activities that require alertness, such as driving or engaging in hazardous activities, until you are aware of how duloxetine affects you. Impaired reactions may occur, and dizziness or fainting could lead to falls, accidents, or serious injuries.
Be mindful of getting up too quickly from a sitting or lying position to avoid feeling dizzy.
If you are taking Drizalma, be cautious about consuming alcohol, as it may heighten the risk of liver damage.

Seek emergency medical help if you experience signs of an allergic reaction to duloxetine, such as hives, difficulty breathing, or swelling in your face or throat. Additionally, contact a healthcare professional promptly if you develop a severe skin reaction, characterized by symptoms like fever, sore throat, burning eyes, skin pain, or a red or purple skin rash with blistering and peeling.
Inform your doctor immediately if you undergo new or sudden changes in mood or behavior, including the onset or worsening of depression or anxiety, panic attacks, difficulty sleeping, impulsivity, irritability, agitation, hostility, aggression, restlessness, increased activity or talkativeness, or if you have thoughts about suicide or self-harm.

Seek immediate medical attention if you observe symptoms of serotonin syndrome, such as agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
Common side effects of duloxetine may include drowsiness, nausea, constipation, loss of appetite, dry mouth, or increased sweating. However, this is not an exhaustive list, and other side effects may occur. Contact your doctor for medical advice regarding any side effects you may experience.
