Heatwave warning as common meds can increase risk of falling ill

Brits on certain meds are being alerted to the heightened risk of illness as temperatures soar. Rising temepratures spell danger for many such as the vulnerable or elderly, especially for those suffering from conditions like heat exhaustion, heat stroke, and dehydration.

However, Sarah Jefferies from Mental Health First Aid Course is specifically cautioning individuals on particular medications to exercise increased vigilance during peak heat periods.

Jefferies has pinpointed specific medication categories that could spell trouble when mixed with scorching weather, urging the public to be well-informed about how their meds may react under extreme heat conditions.


For those on diuretics, commonly prescribed for heart-related issues, the danger of dehydration intensifies with the heat.

Jefferies’ advice is clear: “Stay hydrated by drinking plenty of water, and consult your GP about adjusting your medication if you’re experiencing prolonged hot weather.”


Moreover, antihypertensive drugs including beta-blockers and ACE inhibitors, can impair the body’s ability to manage high temperatures, potentially leading to cardiac problems.

Jefferies recommends that individuals taking these medications should keep a close eye on their blood pressure during heatwaves to prevent any unforeseen health issues.


Antidepressants also made it to the list of Jefferies’ concerns, as some can mess with the body’s ability to control temperature, making it harder for those on medication to sweat and cool down.

Sarah has a tip for those affected: “Wear lightweight, breathable clothing and seek shade or air-conditioned environments when possible.”


Antipsychotic medications, including chlorpromazine and haloperidol, may also impair the body’s temperature regulation, increasing the risk of heat stroke during sweltering weather.

Sarah recommends that individuals taking these drugs should frequently monitor their body temperature and steer clear of excessively hot settings.


Stimulant drugs, commonly prescribed for ADHD such as amphetamines like Adderall and methylphenidate like Ritalin, can raise the body’s core temperature. This could lead to an increased danger of overheating, especially in high temperatures.

The expert’s advice is to “Limit physical activity during the hottest parts of the day and ensure you stay well-hydrated.”
