Does fluvoxamine increase anxiety? (3+ tips)

In this article, we will discuss whether fluvoxamine increases the level of anxiety as a side effect or not. We will also discuss what research suggests on this, the potential relationship between fluvoxamine and increased anxiety, symptoms related to increased anxiety and what to do if you experience fluvoxamine-induced anxiety.

Does fluvoxamine increase anxiety?

Yes, fluvoxamine (Luvox) can increase the level of anxiety in some individuals as a side effect. It’s important to remember that every person is different and responds differently to medications, so not everyone will experience this side effect. (1)

Fluvoxamine is an antidepressant which belongs to the class of drugs known as selective serotonin reuptake inhibitors (SSRIs). It works primarily by increasing the levels of serotonin, a neurotransmitter in the brain which plays a crucial role in regulating mood. (1)

If you start taking fluvoxamine and notice more anxiety or any other concerns, talk to your healthcare provider. They can evaluate your situation and make adjustments to your treatment plan if necessary.  

What is the relationship between fluvoxamine and increased anxiety?

Fluvoxamine is a medication often used to help with anxiety, obsessive-compulsive disorder (OCD) and depression. However, like any medication, it can affect people differently. For some people, it might cause an increase in anxiety as a side effect. (1,2)

Fluvoxamine works by increasing serotonin levels in the brain which helps with mood regulation and its higher levels are usually associated with improved well-being and reduction in anxiety symptoms. 

However, during the early stages of treatment, some individuals may temporarily experience heightened anxiety. This paradoxical effect is not fully understood but it often diminishes as the body adjusts to the medication. 

The primary mechanism involves blocking the reuptake of serotonin and allowing it to stay longer in the brain. If someone experiences persistent or concerning side effects, it’s important to consult with your doctor.

They can assess your situation, consider potential adjustments to your treatment plan or explore alternative medications. The goal is to find a balance that effectively addresses your symptoms with the fewest side effects.

What does research suggest?

Research indicates that while fluvoxamine is commonly prescribed for the treatment of depression, anxiety disorders and obsessive-compulsive disorder (OCD), there is a potential for increased anxiety as a side effect in some individuals. (2)

A study was conducted on 128 children who were 6-7 years of age for the treatment of social phobia or generalized anxiety disorder. The children were randomly assigned to be given fluvoxamine at a maximum dose of 300mg per day for 8 weeks. (5)

The results showed that 5 children in the fluvoxamine group (8%) discontinued taking fluvoxamine because of its side effects which included heightened anxiety during the start of treatment as well. (5)

However, it’s essential to remember that research shows variations in individual responses. Studies and clinical trials have found that some people may experience heightened anxiety when taking fluvoxamine, especially during the initial course of treatment. 

This could be related to the impact of fluvoxamine on serotonin levels in the brain. It’s important to note that research doesn’t suggest that everyone will experience increased anxiety, and many people find fluvoxamine beneficial in managing their anxiety symptoms. (1)
