Duloxetine is often prescribed as a means to treat either anxiety or depression. It is also used to relieve the pain caused to patients suffering from nerve damage due to diabetes (also known as diabetic peripheral neuropathy).
It can also be used to treat muscle pain and stiffness (fibromyalgia), as well as the long-lasting, chronic pain related to bones and muscles.
The drug Duloxetine is a part of a group of drugs known as SNRIs, which stands for selective serotonin and norepinephrine reuptake inhibitors. Essentially, these work by increasing the activity of norepinephrine and serotonin in the brain.
To obtain Duloxetine, a patient must first undergo a full medical examination and then receive a prescription. This drug has the potential to cause a wide variety of adverse side effects and is strictly suitable for certain patients only. For this reason, never seek to obtain and use Duloxetine on your own.
Just like most other drugs, Duloxetine can potentially cause a wide range of different side effects to occur. Some of these are not very serious, but others are more so. If you experience any of the side effects as listed directly below, then contact your doctor immediately for assistance.
