Oxytocin nasal spray

At a glance

Compared with other treatments

Against a dummy spray, both with exposure therapy: symptoms improved by about the same amount in both groups.

What it takes

Not available as a treatment for social anxiety.

What it is

Oxytocin is a hormone your body makes. It plays a part in childbirth, breastfeeding and bonding, which is why newspapers call it the “love hormone”. In lab studies, a nasal spray of oxytocin made social threats seem smaller and helped people pick up friendly social signals.

That led to a hopeful idea. If oxytocin makes social contact feel safer, maybe it could help people with social anxiety get more out of therapy.

Why people are interested

Social anxiety is a fear of other people. A hormone linked to trust and closeness sounds like a natural fix. The idea also fits how exposure works. If you feel a little safer with people during practice, you might stay in the situation longer and learn more from it.

There is also a simple appeal. A nasal spray is easy. It does not ask you to change how you think or to face anything. That is exactly why it is worth being careful: the easier a fix sounds, the more proof it needs.

What the evidence shows

In an Australian trial, 25 adults with social anxiety disorder had exposure therapy: facing feared situations on purpose, in small steps. Alongside the sessions, they used either an oxytocin nasal spray or a dummy spray (a placebo). Nobody knew which they got.

• Feeling a bit better about yourself. People on oxytocin rated their appearance and their speeches more positively as the sessions went on.
• No difference in the end. Social anxiety symptoms, anxious thinking and problems in daily life improved about the same amount in both groups.

The authors suggested the effect might be short-lived or tied to the moment. They called for more research, for example with more frequent doses.

What the trial could not answer

With only 25 people, the trial could have missed a small benefit. It tested one dose in one way, alongside exposure therapy. We don’t know whether different doses, more frequent use, or use with other kinds of therapy would change the result. But a treatment needs a trial showing it helps before it can be recommended, and oxytocin does not have one.

Lab studies also used healthy volunteers more often than people with social anxiety. A small change in how a face looks in a lab is a long way from feeling at ease at a party or in a meeting.

What this means for you

• Oxytocin is not a treatment for social anxiety. It is not approved for this anywhere we know of.
• Be wary of sprays sold online as “oxytocin” for confidence or social ease. No trial supports them for social anxiety. Talk to a doctor before using any hormone product.
• The therapy worked. In this trial, both groups improved with exposure therapy. Cognitive therapy for social anxiety and exposure on your own have much stronger evidence.

Questions to ask about any “social confidence” product

1. Was it tested in people with social anxiety, or only in healthy volunteers?
2. Did it beat a fake version (a placebo)?
3. Did it change real life, or only how people felt in a lab task?
4. Is it approved for this use where you live?

If the answer to any of these is no, treat the claim with care.

Why this matters

Oxytocin is one of several ideas that looked good in the lab, with healthy volunteers and single doses, and did not help in a real treatment trial. D-cycloserine and attention training followed the same path. That is a good reason to wait for proper trials before trusting any new “social confidence” product.
