How Pregabalin Works

Pregabalin binds to specific calcium channels on nerve cells in the brain and spinal cord. This reduces the release of certain neurotransmitters involved in pain signaling and abnormal electrical activity.

It helps to:

• Reduce nerve pain.
• Decrease seizure activity when used with other anti-seizure medicines.
• Reduce pain and tenderness associated with fibromyalgia.
• Calm excessive nerve activity linked to generalized anxiety disorder in countries where it is approved for that use.
