Storage Requirements for Phenergan Products
Temperature and Environmental Conditions
Phenergan tablets and elixir should be stored at room temperature, ideally between 15-25°C. Avoid exposing the medication to extreme temperatures, direct sunlight, or heat sources such as radiators or sunny windowsills. High temperatures can cause the active ingredient promethazine to degrade, potentially reducing its effectiveness for treating allergies, nausea, or sleep difficulties.
Original Packaging Protection
Always keep Phenergan in its original packaging until use. The blister packs for tablets and amber bottles for elixir are specifically designed to protect against light and moisture. The packaging also contains important information including expiry dates and batch numbers. EverydayMeds supplies both Phenergan 25mg tablets (56 tablets) and Phenergan Elixir 5mg/5ml (100ml) in manufacturer-sealed packaging.
Moisture Control and Location
Store Phenergan in a dry location away from humidity. Avoid storing in bathrooms, kitchens, or other areas where steam and moisture are common. Moisture can cause tablets to break down and affect the stability of liquid formulations. A bedroom drawer or dedicated medicine cabinet in a cool, dry room is ideal.
Safety and Child Protection
Keep all promethazine products securely stored away from children and pets. Consider using a locked medicine cabinet or high shelf that children cannot access. The sedating effects of Phenergan make it particularly important to prevent accidental ingestion by children.
Liquid Formulation Considerations
Phenergan Elixir requires additional storage care. Store the bottle upright to prevent leakage and ensure the cap is tightly closed after each use. Check the liquid regularly for any changes in colour, consistency, or odour that might indicate deterioration. The oral solution should remain clear and maintain its original appearance.
Expiry and Disposal
Regularly check expiry dates and never use Phenergan beyond its expiration. Dispose of expired medications safely through pharmacy return schemes rather than household waste. Both tablet and elixir formulations lose potency over time, and expired antihistamines may not provide adequate symptom relief.
