How to store Lantus correctly

Improperly stored medication loses potency and, in some cases, becomes unsafe. Lantus (Insulin Glargine) is supplied as pre-filled pen, vial at 100 IU/mL and, like most modern oral medications, is stable under normal household conditions when stored as directed. A few simple rules cover most of the practical risks.

Standard storage for Lantus

According to the prescribing information for Insulin Glargine, Lantus should be kept at controlled room temperature in the original packaging, away from direct sunlight and excessive humidity. Bathrooms and the area near a stove are not ideal because of humidity and temperature swings. The kitchen drawer or a closet shelf is usually fine.

Shelf-life and child safety

Each Lantus pack has a printed expiry date; tablets should be discarded after that date. pre-filled pen, vial that look discoloured, broken or smell different from the original packaging should not be used. Where a household includes children, Lantus should be stored well out of reach in a closed container, ideally with a child-resistant cap.
