The number of 12-to-17 year olds prescribed antidepressants in England more than doubled between 2005 and 2017. This is one of the striking changes seen in a new study into the use of antidepressants by children and young people. It also found that antidepressant prescriptions for 5-to-11 year olds decreased between 1999 and 2017.
Antidepressants are not usually recommended as the first treatment for those under 18 years because of a lack of evidence on whether they are safe and effective in young people. But prescriptions have risen in the UK and elsewhere.
This study also found that children and young people living in deprived areas were more likely to be prescribed antidepressants than those from affluent areas. Teenagers from Black, Asian and other ethnic minority (BAME) groups were less likely than White teenagers to be prescribed antidepressants.
Further research is needed to explore the reasons behind these findings. The rise in antidepressant use in 12-to-17 year olds could be due to increasing rates of depression in young people. They may be more aware of mental health and more likely to seek help. Or it may suggest that young people are unable to access other treatments such as cognitive behavioural therapy and other talking therapies.
The regional and ethnic variation in antidepressant prescriptions might be due to differences in the number of young people experiencing depression. Or it might suggest people from certain areas or groups have difficulty accessing mental health services.
What’s the issue?
Compared with adults, children with depression can be underdiagnosed and undertreated. They can experience problems at school and might be at risk of attempting suicide.
Talking therapy with a counsellor or psychologist is considered the main treatment for depression in children but almost a quarter of young people wait more than six months to see a mental health specialist in England. Antidepressants are often prescribed by their GPs instead.
However, it is not known how safe or effective these medicines are for children. The UK NICE guideline for depression in children and young people recommends only selected antidepressants for young people with moderate or severe depression. They should be given alongside talking therapies, following assessment by a mental health specialist.
Antidepressant use among young people was increasing until a drop in 2002, linked to concerns about safety and possible increases in suicidal behaviour. Use began to increase again from 2005. Prior to this study, it was unclear whether the rise in antidepressant prescribing was still continuing.
Previous research has shown that children living in deprived areas are more likely to be prescribed antidepressants. However, it was not known if young people from particular regions or ethnic groups are more likely to be prescribed antidepressants.
Researchers analysed the health records of more than 4 million 5-to-17 year olds in England from 1998 to 2017. This anonymised information came from the primary care database QResearch. They considered four types of prescription: selective serotonin reuptake inhibitors (SSRIs), tricyclic and related antidepressants (TCAs), serotonin and norepinephrine reuptake inhibitors (SNRIs) and other antidepressants.
They found that:
- antidepressant prescriptions for 5-to-11 year olds fell between 1999 and 2017 due to a decrease in TCA prescriptions, although there was a slight increase in SSRI prescriptions
- antidepressant use in 12-to-17 year olds more than doubled between 2005 and 2017
- prescriptions for the SSRIs fluoxetine and sertraline increased most over the study period
- children and young people in London were least likely to be prescribed antidepressants; those in South East England were most likely
- children and young people living in more deprived areas were more likely to be prescribed antidepressants
- fewer BAME teenagers were prescribed antidepressants, compared to White teenagers.
Why is this important?
Antidepressant use in teenagers is increasing. However, it is not clear whether this is due to growing rates of mental health problems, greater awareness of mental health issues or a lack of access to talking therapies.
The variation in antidepressant prescribing in different regions and ethnic groups suggests there could be health inequalities in access to appropriate care for certain children and young people with mental health problems.
Further research is needed to understand why these patterns in antidepressant prescribing among children and young people exist.
Researchers could look at whether certain groups are more likely to experience depression, or if some young people experience more difficulty accessing mental health diagnosis and support than others.
The recent increase in sertraline prescriptions was surprising. Sertraline is licensed for treating obsessive-compulsive disorder (OCD) and only recommended as a second-line treatment for depression. OCD is rare in England so does not explain the high use of sertraline.
Although there are currently no UK guidelines on treating children and young people with anxiety, research has found SSRIs, including sertraline, can help. GPs may be following the adult guidance for anxiety, which suggests prescribing sertraline. Clinical guidelines for helping children with the full range of anxiety disorders are needed.
