A pharmaceutical expert warns against common medication storage mistakes that can reduce drug effectiveness.

Weekly pill organizers, while convenient, also present risks if not used correctly, potentially leading to incorrect dosage or compromised drug quality. The aluminum blister pack is designed to protect the pills from environmental factors until the moment of consumption. Experts recommend keeping medications in their original packaging until shortly before taking them. Understanding the purpose of blister packs is crucial for ensuring medications maintain their potency and deliver the intended therapeutic benefit.
