APO-Latanoprost
Yes, APO-Latanoprost eye drops require specific storage conditions to maintain their effectiveness:
-
Unopened Bottles: Store in the refrigerator at temperatures between 2°C and 8°C. Protect from light and do not freeze.
-
Opened Bottles: Once opened, the bottle may be stored at room temperature, up to 25°C, for up to six weeks. After this period, any unused solution should be discarded
Why Storage Matters
Keeping Latanoprost at the right temperature preserves its stability and effectiveness. If exposed to higher temperatures, the active ingredient can break down, reducing its ability to lower eye pressure. Additionally, light exposure can degrade the solution, so it’s important to store your bottle in its original packaging.
Shelf Life of Latanoprost
Unopened Bottles
If stored as directed by their respective manufacturers, unopened bottles or containers of Latanoprost (Xalatan and Apo-Latanoprost) remain effective until the expiry date printed on the packaging.
Opened Bottles
The shelf life after opening is 4 weeks if stored at room temperature.
How to Store Latanoprost When Travelling
Whether you're heading to Sydney, enjoying a holiday in sunny Queensland, or travelling across Australia and beyond, keeping your Latanoprost stored safely is essential. Here are some tips:
- Use a Medical-Grade Eye Drops Carrying Case. Brands like 4AllFamily Australia offer specialised cooling cases that can maintain a safe temperature range for several days of travel. These cases often come with options for USB power or can be used with simple cold packs, making them versatile for various travel scenarios.
- Keep Latanoprost in the Shade. Always store your eye drops out of direct sunlight. Even brief exposure to sunlight can increase the temperature of your eye drops above the safe threshold of 25°C, risking degradation of the active ingredients.
- Minimize Handling: Try to handle the medication as little as possible. Since Latanoprost is typically administered at night, plan to keep it stored in a cool place at home or in your hotel room while you’re away. If you won’t return to your accommodation until after your usual dosing time, take the cooling case with you but avoid opening it until needed.
And remember, travelling with temperature-sensitive medications like Latanoprost requires to always plan ahead and consider the length of your journey and the storage facilities available at your destination to choose the best cooling solution to keep your eye drops safe and effective!
