Quick Answer: Kesimpta must be kept refrigerated between 2°C to 8°C until ready for use. It can stay at room temperature, not exceeding 30°C, for up to 7 days.
Have you been prescribed Kesimpta and are unsure about how to store it or take it with you when travelling? You’re in the right place!
Proper storage is absolutely essential to ensure your MS injection remains effective. In fact, Kesimpta can lose its potency quickly if it isn’t stored or refrigerated correctly.
To help, we’ve put together a complete guide covering everything you need to know about storing Kesimpta safely, how long it can be kept out of the fridge, and tips for travelling with your medication securely.
What is Kesimpta?
Kesimpta is a prescription medicine prescribed in the UK to treat relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting MS, and active secondary progressive MS in adults.
Its active ingredient, ofatumumab, is a monoclonal antibody that helps reduce the inflammation that drives MS, resulting in fewer relapses and a slower progression of disability.
Kesimpta is self-administered via subcutaneous injections (just under the skin) using pre-filled SensoReady pens. These pens contain 20 mg of ofatumumab in a 0.4 mL solution, offering an easy-to-use option for patients at home.
Important: Kesimpta is only available with a prescription and must be used under the guidance of a qualified healthcare professional. Never take Kesimpta without consulting your doctor.

Kesimpta Storage Temperature
According to Novartis, the manufacturer, Kesimpta should be stored in a refrigerator at 2°C to 8°C. Always keep it in its original packaging to shield it from light and avoid freezing or shaking the pen. Also, do not use it if the pen has been dropped or damaged.
How long can Kesimpta be out of the fridge?
Kesimpta can be at room temperature, not exceeding 30°C, for up to 7 days. Once it has been taken out of the fridge, it must not be put back in, and any unused medication after this period should be discarded.
For the best results, try to minimise the time Kesimpta spends unrefrigerated, as prolonged exposure to higher temperatures can compromise its effectiveness.
Avoid situations where the pens are exposed to temperatures above 30°C altogether.
Kesimpta Travel Coolers
Travelling with injectable MS treatments such as Kesimpta requires careful planning, especially as they need to be kept within specific temperature ranges. However, with the right coolers, it’s entirely manageable.

A medical-grade cooler is essential for keeping Kesimpta safe while travelling. Products like those from 4AllFamily UK are specifically designed for this purpose. Here are two options that are particularly popular among Kesimpta users:
- The Voyager Mini Travel Fridge for Medications can maintain fridge temperatures (2°C to 8°C) for unlimited time when plugged to a USB power source like a portable power bank, a portable solar panel, a car cigarette lighter or others. When unplugged and used with biogel cooling packs, it will keep your Kesimpta pens refrigerated for up to 30 hours.
- The Chillers Cooling Pouches are extremely convenient for keeping Kesimpta pens cool at room temperature, protected from the heat (but not refrigerated, so it's a valid option for trips up to 7 days!). They work without the need for a freezer nor electricity, and all you need is water to keep your injections cool for up to 45 hours!
Before travelling with Kesimpta
- Check travel rules: Familiarise yourself with regulations for carrying medicines at your destination.
- Pack it in your hand luggage: Always keep Kesimpta in your carry-on when flying, as checked luggage is often exposed to extreme temperatures.
- Carry documentation: Bring a doctor’s letter and a copy of your prescription, especially for international travel or travelling within the UK with more than 100ml of medication.
- Keep the original packaging: This ensures all necessary information is easily accessible for airport security or customs.
