Pharmacist Raj Patel, with over 35 years of experience, has issued an urgent warning about 10 medications that require special attention during the current heatwave, as temperatures are set to exceed 30°C in parts of the UK. In a TikTok video, Patel emphasized that this is not a reason to stop taking medication but rather to plan ahead.
Medications at Risk
The 10 medications identified are: Furosemide, Ramipril, Losartan, Amlodipine, Bisoprolol, Oxybutynin, Amitriptyline, Sertraline, Empagliflozin, and Insulin. According to Patel, these drugs can affect fluid balance, sweating, blood pressure, heart rate, kidneys, blood sugar, or the body's cooling mechanisms, making heat more risky.
Furosemide
This water tablet helps remove extra fluid but can increase dehydration risk in hot weather. The NHS advises drinking more water when taking this medicine and consulting a pharmacist if unsure.
Ramipril and Losartan
Ramipril, an ACE inhibitor, and Losartan, an ARB, are used for blood pressure and heart or kidney protection. Dehydration can worsen dizziness, low blood pressure, or kidney strain.
Amlodipine and Bisoprolol
Amlodipine, a calcium channel blocker, may cause ankle swelling, flushing, dizziness, or headaches that feel worse in heat. Bisoprolol, a beta blocker, slows heart rate and affects the body's response to heat and exercise.
Oxybutynin and Amitriptyline
Oxybutynin, for bladder symptoms, can reduce sweating, hindering cooling. Amitriptyline, used for nerve pain or sleep, may cause drowsiness, dry mouth, and affect heat tolerance.
Sertraline and Empagliflozin
Sertraline, an SSRI antidepressant, can cause increased sweating, dizziness, or changes in temperature tolerance. Empagliflozin, an SGLT2 inhibitor for type-2 diabetes, increases urine output, raising dehydration risk.
Insulin
Heat, extra walking, missed meals, alcohol, and dehydration can affect blood sugar. The NHS advises storing unopened insulin in the fridge and carrying current insulin in a cool bag or pouch when out.
Pharmacist's Advice
Patel urged people not to stop prescribed medicines suddenly unless a healthcare professional advises. Instead, he recommended planning ahead, staying hydrated, keeping cool, and storing medicines properly. The NHS also advises those on multiple medications to be particularly cautious during hot weather.
Tips for Coping in Hot Weather
The NHS recommends keeping out of the heat, consuming cold food and drinks, avoiding caffeine and hot drinks, and keeping living spaces cool by closing windows and curtains during the day and opening them at night. If unsure about taking medication during the heatwave, consult a healthcare professional.
