Background: Good storage practice is fundamental to prevent the deterioration of medications and to ensure their quality and safeties are maintained. This case study focuses on maintaining proper storage conditions without risking degradation. Case Presentation: An incident occurred in a paediatric pharmacy in Al-Sabah hospital, Al-Sabah medical area, Kuwait, in September 2021; an 11-year-old child diagnosed with weakness in the gastroesophageal valve and a physician prescribed omeprazole suspension preparation as an oral dosage form for daily based using. After dispensing 30 bottles from the pharmacy, the patient's parent stored all quantities dispended at room temperature rather than refrigerated. However, the medication company stated that the patient or healthcare giver should refrigerate before and after opening the bottle. Due to this inappropriate storage practice, the suspension preparations deteriorated and spoiled. Conclusion: Inappropriate dosage practices are preventable by simple solutions. Preparing training and assessment programs for pharmacists is essential to focus on the importance of proper and complete patient counselling and to ensure that the patient or healthcare giver stores medications in special storage conditions. Moreover, creating a policy for dispensing drugs that require specific storage conditions, such as labelling medications with specific storage conditions with specific-coloured labels and dispensing cooling boxes for them.
