The National Agency for Food and Drug Administration and Control (NAFDAC) has warned that rising heatwaves across the country could compromise the potency and safety of medicines if proper storage conditions are not maintained.

The agency said extreme temperatures can reduce the effectiveness of several drugs, especially those that require cool storage such as vaccines, insulin, antibiotics, and certain syrups.

According to health officials, prolonged exposure to heat can alter the chemical composition of medications, making them less effective or potentially unsafe for consumption.

NAFDAC urged pharmacies, hospitals, and pharmaceutical distributors to strictly adhere to recommended storage guidelines, including temperature control systems and proper packaging.

The agency also advised the public to avoid purchasing drugs from unregulated sources, warning that exposure to heat during roadside or open-air sales could render medicines ineffective.

Health experts say the warning is particularly important during the current hot season, where temperatures in many parts of the country have risen significantly above average levels.

NAFDAC emphasized that maintaining drug quality is essential for effective treatment outcomes and overall public health safety.

The agency reaffirmed its commitment to monitoring pharmaceutical distribution channels and enforcing compliance with safety standards nationwide.

It also called on healthcare providers to educate patients on proper drug storage at home to prevent deterioration caused by heat exposure.
