Pregalin 50 Capsule is used to relieve long-term (chronic) pain caused by nerve damage from diabetes, shingles, or a spinal cord injury. It alleviates pain and its accompanying symptoms, such as mood swings, sleep disturbances, and fatigue. It is considered to act by interfering with pain signals sent by damaged neurons to the brain. This medication, taken on a daily basis, will improve your physical and social functioning, as well as your general quality of life. It takes a few weeks to work, so take it on a regular basis, even if you don't think it's helping. After your symptoms have subsided, you should continue taking the medication until your doctor recommends you to stop.
