NHS Guidelines for Aciclovir Storage Requirements
Aciclovir Tablet Storage Requirements
Aciclovir 400mg tablets should be stored at room temperature, ideally below 25°C. Keep tablets in their original blister packaging to protect from moisture and light. The foil backing serves as a barrier against humidity, which can cause tablets to deteriorate. Never transfer tablets to different containers, as this removes crucial protection and may lead to confusion with other medications. Store in a cool, dry place such as a bedroom drawer or kitchen cupboard away from the cooker and sink.
Cream Storage Guidelines
Aciclovir 5% cream requires careful storage to maintain its consistency and effectiveness. Keep tubes in their original cartons and store below 25°C. Avoid storing in car glove compartments during summer months, as temperatures can exceed safe storage limits. The cream should never be frozen, as this can cause separation and reduce effectiveness. Always replace the cap tightly after use to prevent contamination and drying out.
Common Storage Mistakes to Avoid
Many patients unknowingly compromise their aciclovir medication through improper storage. Bathroom medicine cabinets are unsuitable due to steam and temperature fluctuations from hot showers. Windowsills expose medication to direct sunlight and temperature variations. Kitchen areas near cookers or radiators can exceed safe storage temperatures. Car storage should be avoided, as temperatures can range from freezing to over 40°C throughout the year.
Signs Your Aciclovir May Be Compromised
Tablets showing discolouration, cracking, or unusual odour should not be used. Aciclovir cream that has changed consistency, separated, or developed an unusual smell may have been compromised by improper storage. If you notice any changes to your medication's appearance, consult your pharmacist before use. EverydayMeds can provide guidance on whether replacement medication is needed.
Safe Disposal and Replacement
Expired or compromised aciclovir should be returned to any UK pharmacy for safe disposal. Never dispose of medications in household waste or down drains. Check expiry dates every six months and ensure you have in-date medication available for cold sore outbreaks. EverydayMeds offers convenient online ordering for aciclovir tablets and cream, ensuring you maintain an effective supply for future cold sore episodes.
