Heatwave Alert: Common Meds Need Care
10 Aug
Summary
- UK government warns about heat affecting common medications.
- Ramipril and bisoprolol may be less effective in heat.
- Heat can increase dehydration and heatstroke risks for patients.
The UK government has cautioned citizens about the potential impact of the current heatwave on certain commonly prescribed medications. Individuals taking drugs such as ramipril, an ACE inhibitor, and bisoprolol, a beta-blocker, are urged to be vigilant. These medications are frequently used to manage high blood pressure, heart failure, and recovery after heart attacks.
The Medicines and Healthcare products Regulatory Agency (MHRA) highlighted that heat can compromise medication effectiveness, especially if stored in hot environments like cars or bags. Elevated temperatures can also exacerbate health risks for individuals on these drugs.
Some medications can increase sensitivity to the sun, leading to quicker burns, dizziness, or dehydration. Most medicines require storage below 25°C to maintain their efficacy. The current heatwave, with temperatures potentially reaching 36°C in parts of England, necessitates heightened awareness.
Public health agencies have issued a yellow heat health alert across England. The MHRA advises that medications like ACE inhibitors and beta-blockers can impair the body's ability to regulate temperature and may reduce thirst responses. This makes patients more susceptible to heat-related illnesses, with risks potentially increasing based on the number of such medications taken.
