Off-label uses

Doctors sometimes prescribe a medicine for a condition it is not officially licensed for. This is called off-label use. It is legal and common when there is good evidence it helps, and your doctor should explain why they are suggesting it.

  • Fibromyalgia
  • Alcohol or benzodiazepine withdrawal (limited evidence)

How it works

Pregabalin attaches to calcium channels on nerve cells and reduces the release of chemical messengers. This calms overactive nerves involved in pain, anxiety and seizures.

Side effects

Like all medicines, Pregabalin can cause side effects, although not everyone gets them. Many are mild and ease after the first few weeks.

Common side effects

  • feeling sleepy or dizzy
  • weight gain
  • blurred vision
  • dry mouth
  • unsteadiness
  • swollen hands or feet
  • constipation

Tell your doctor or pharmacist if these bother you or do not go away.

Serious side effects

These are rare. Call 111 or contact your doctor straight away if you get:

  • slow or shallow breathing, especially if you also take opioids. Call 999
  • thoughts of harming yourself
  • signs of dependence, such as needing more to get the same effect

Call 999 if you have signs of a serious allergic reaction, such as swelling of your lips, mouth, throat or tongue, or trouble breathing.

You can report any side effect to the Yellow Card scheme, run by the medicines regulator.

Stopping and withdrawal

Important safety information

  • It is a controlled drug and can cause dependence and misuse.
