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.

Social anxiety and panic disorder

How it works

Fluvoxamine is a selective serotonin reuptake inhibitor (SSRI). It increases serotonin in the brain, which can reduce obsessive thoughts and improve mood.

Side effects

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

Common side effects

feeling sick
feeling sleepy or having trouble sleeping
headache
dry mouth
sweating
feeling restless
sexual problems

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:

thoughts of harming yourself
unusual bleeding or bruising
fits
signs of serotonin syndrome

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.
