What Is Pregabalin?

Pregabalin is a prescription-only medicine used to treat several conditions involving the nervous system.

Healthcare professionals may prescribe pregabalin for:

• Neuropathic (nerve) pain

• Generalised anxiety disorder (GAD)

• Epilepsy as an additional treatment

Pregabalin works by affecting nerve signals within the body and brain. Treatment plans are tailored to individual patient needs, which is why different strengths are available.

Why Does Pregabalin Come in Different Strengths?

Not every patient requires the same dosage.

Healthcare professionals consider factors such as:

• Medical condition

• Symptom severity

• Age

• Kidney function

• Previous treatment history

• Individual response to medication

Having multiple strengths available allows treatment to be adjusted gradually and safely.
