Heatwave Warning: Mental Health Meds Raise Heat Risk
2 Jul
Summary
- Some mental health medications can hinder the body's ability to cool.
- Antidepressants and antipsychotics may increase risks of dehydration.
- Patients on these meds should take extra precautions during hot weather.

Doctors are advising individuals on specific mental health medications to take extra precautions as temperatures are predicted to rise significantly in Britain this weekend. Medications such as selective serotonin reuptake inhibitors (SSRIs) and certain antipsychotics can impair the body's ability to cool down, leading to increased risks of dehydration, heat exhaustion, and heat stroke.
Experts emphasize that patients should not stop their medication abruptly but should instead consult their GP, pharmacist, or mental health team if they experience adverse effects. This warning comes as the Met Office forecasts temperatures potentially reaching 29C, with the heatwave possibly lasting up to 10 days, marking the third heatwave of the year. Previous heatwaves have already highlighted the vulnerability of those on these medications.
Personal accounts, like that of a 22-year-old taking both antidepressants and antipsychotics, illustrate the severe impact, with experiences of heat exhaustion and migraines during intense heat. Mental health charities and professional bodies are reinforcing advice to stay hydrated, wear light clothing, and seek shade during the hottest parts of the day. They stress that while heat management can be challenging, the medications remain safe and necessary when taken as prescribed.
