However, the oral capsule can be available for both a generic and brand-name drug.
This drug does have a Black Box Warning, which is a FDA warming that alerts both doctors and patients of dangerous effects. It is possible that this drug can make your depression worse. Please reach out to your doctor if you have any questions or concerns.
What is Duloxetine?
Duloxetine is a prescription drug, and it can be used as an oral capsule. It can help treat anxiety, depressive disorder, nerve pain, fibromyalgia pain, and chronic muscle and joint pain. Duloxetine belongs to a class of drugs called serotonin-norepinephrine reuptake inhibitors (SNRIs). The drug acts by balancing the chemicals within the brain that can cause anxiety and depression. Because pain signals are interpreted in the brain, the drug also works to inhibit these pain signals through the balancing of these chemicals.
It is important to follow your doctor’s directions while taking the drug. Only take as directed, especially because it can be a long-term medication. Depending on what your condition is, how you first react to the drug, and the severity of your condition, your doctor can recommend a different dosage.
Fibromyalgia: Adults with fibromyalgia who are 18 years and older tend to have a starting dosage of 30 mg per day for one week. Then, it goes onto 30 to 60 mg per day.
Major Depressive Disorder: Adults can receive 30 to 60 mg per day at first. Then, the maintained dosage can be between 40 to 60 mg per day.
Generalized Anxiety Disorder: Similar to major depressive disorder, generalized anxiety disorder can start with a dosage of 30 to 60 mg per day. Then, it is usually given as 60 mg per day. Children between the ages of 7 and 17 years old and adults 65 years and older can take this drug. However, they are given a lower dosage (about 30 to 60 mg).
Nerve Pain (Diabetes): Adults are given a 60 mg dosage per day.
Chronic Muscle and Joint Pain: Adults begin with 30 mg per day for one week, and then they tend to take 60 mg per day afterwards.
