Lantus is a popular insulin medication that doctors prescribe to patients with diabetes to help them with daily blood sugar control. This medication is considered to be long-acting and doses work for up to 24 hours. It can be found in a vial or an injection pen form. Patients using this medication may also be prescribed to use other short-acting insulins at the same time.
This medication may be found in the form of a 10 mL multi-dose vial or a 3 mL prefilled Lantus Solostar pen. Its formulation is usually U-100 and it is prescribed to patients to be taken once per day. The exact dose the patient is prescribed may vary depending on the type of diabetes the patient has and their specific needs.
Patients taking this medication can do so by:
The patient should check their blood sugar regularly while taking this medication. Those using the pen version of this medication should follow the instructions given to them by their doctor and on the packaging.

Patients should speak with their doctor or healthcare provider if they have any concerns or if side effects become severe.
Some less common side effects may indicate a medical emergency. Patients experiencing any severe side effects – such as having a serious allergic reaction – should seek immediate medical attention. Signs of serious side effects include those such as:
Patients experiencing any of these side effects should get medical attention right away.
Missed doses of Lantus should be taken as soon as it is remembered in many cases. The missed dose should be skipped and the next dose taken at the regular time if it is almost time for the next scheduled dose or the next day has arrived. Doses should not be doubled or taken together to make up for a missed dose.
Serious side effects may occur from taking too much of this medication. This may lead to effects such as dangerously low blood sugar or potassium levels. Patients who have taken too much of their medication should contact their doctor right away. Patients experiencing an emergency from too much of this medication may also contact poison control or call their local emergency service number.
Lantus vials should be kept in the refrigerator at 36°F to 46°F (or 2°C to 8°C) until they have been opened. Patients should be careful not to freeze this medication or expose it to direct light. Opened vials of this medication can either be stored the same way or kept at room temperature – between 59°F and 86°F or 15°C and 30°C. Any remaining medication should be disposed of within 28 days after opening.
