Toujeo 300 U/mL Solostar is a long-acting type of insulin used to treat types 1 and 2 diabetes mellitus in both adults and children. It provides a steady level of insulin in the body for an entire day and helps control blood sugar levels. This helps to prevent complications of diabetes.

Toujeo 300 U/mL Solostar can be prescribed alone or along with fast-acting insulin or other diabetes medicines. Your doctor or nurse will teach you the correct way of injecting it under the skin. You should use this medicine regularly as per the dose advised to get the maximum benefit. If you stop taking it, your blood sugar levels may rise very high which may put you at risk of serious complications. It is only a part of the treatment program that should also include a healthy diet, regular exercise and weight reduction as advised by your doctor.

The most common side effect of this medicine is low blood sugar levels (hypoglycemia). To prevent this, it is important to inject only the correct dose of medicine, have regular meals, and monitor your blood sugar levels regularly. Drinking excessive alcohol can also lead to a fall in your blood sugar levels. Other side effects include allergy at the injection site like redness, swelling, or hard lumps (lipohypertrophy). Some people gain weight while taking insulin.

Do not use this medicine when you have low blood sugar levels. Before starting the treatment, inform your doctor if you have ever had kidney, liver or heart problems. Pregnant or breastfeeding women should consult their doctor before using it.

User Feedback


Q. What kind of insulin is Toujeo 300 U/mL Solostar?

Toujeo 300 U/mL Solostar is a man-made insulin, which is very similar to human insulin. It has a long and steady (constant) effect on the blood sugar levels and the action lasts for an entire day. This makes it suitable to be used once daily. It is used to treat type 2 diabetes mellitus in adults and type 1 diabetes mellitus in adults and children.

Q. How is Toujeo 300 U/mL Solostar administered?

Toujeo 300 U/mL Solostar is injected just below the skin (subcutaneously). Your doctor will train you on the correct method and the areas (abdomen or stomach, thighs, arms, hips or buttocks) where you should inject it. It is advised that the site of injection should be changed within the chosen area of skin, for every dose. For example, if you have been advised to inject it into the skin of your stomach, avoid puncturing the same point on your stomach every day. Rather, inject the needle at a site that is slightly away, say around 1cm, from the previous injection. You can also consider switching sides while injecting, like choosing the right side on one day and the left side on the next day. This way, you can reduce the complications associated with repeated injections in the same site such as thickening of the fat tissue below the skin known as lipodystrophy, irritation, pain etc. After one to two weeks, you should move to another area of your body (eg. from the stomach to the arms or thighs) as advised by your doctor. Consult your doctor if you face any problems while injecting Toujeo 300 U/mL Solostar.

Q. Can I take Toujeo 300 U/mL Solostar twice a day?

Toujeo 300 U/mL Solostar is long-acting and is usually prescribed to be taken once a day. It can be taken at any time of the day, but try to take it at the same time each day.

Q. What will happen if I accidentally inject more than the prescribed dose of Toujeo 300 U/mL Solostar?

If you have accidentally taken more than the prescribed dose of Toujeo 300 U/mL Solostar, your blood sugar levels may become too low (hypoglycemia). This hypoglycemia may be mild or severe. Monitor your blood sugar levels more frequently for the next 24 hours. Mild episodes of hypoglycemia (with symptoms like anxiety, sweating, weakness, tremors, fast heartbeat) can usually be corrected with the help of sugary foods such as sugary candy, fruit juice, and glucose/glucon-D. However, it is important to consult your doctor to decide the further course of treatment. More severe episodes of hypoglycemia may even lead to a seizure (fit) or unconsciousness. This can be life-threatening and the patient should be rushed to an emergency.

Q. How should Toujeo 300 U/mL Solostar be stored?

Keep this medication out of the reach of children in the container it came in. Store unopened vials and pens in the refrigerator, but do not freeze them. An unopened, Toujeo 300 U/mL Solostar can be stored in the refrigerator until the date shown on the company's label. Moreover, never use Toujeo 300 U/mL Solostar that has been frozen or defrosted. If a refrigerator is unavailable, the vials can be stored at room temperature and away from direct sunlight and extreme heat. It should appear as a clear, colorless solution that is free from any particles.

Q. In what circumstances will the dose of Toujeo 300 U/mL Solostar need to be changed?

You should consult your doctor about the scenarios where you may need to adjust your insulin dose. For example, in case you are ill, you should monitor your blood sugar levels more closely. You must tell your doctor about all the medicines that you are taking because many medicines can affect the way insulin acts and you may need dose modification. Your eating habits may also affect your dose, for example, if you eat less someday, skip a meal or eat more than what you usually eat. Your blood sugar level may alter depending upon your exercise regime, alcohol consumption or stress. Pregnant and breastfeeding mothers should consult their doctor before taking Toujeo 300 U/mL Solostar as they may need to change their dose.

Q. What are the serious side effects of Toujeo 300 U/mL Solostar?

Serious side effects are rare with Toujeo 300 U/mL Solostar. Sometimes, severe allergic reaction may be seen with it. This can lead to rash, hives, itching all over the body, trouble breathing (wheezing), fast heart rate, and low blood pressure. Get medical help right away if you develop any of these symptoms. Other side effects include severe hypoglycemia (low blood sugar levels), that can cause dizziness, sweating, anxiety, confusion, headache, blurred vision, slurred speech, shakiness, fast heartbeat, seizure (fit), and unconsciousness. Taking certain medicines such as TZDs (thiazolidinediones) may cause heart failure in some people, even if they have never had any heart problems before. Some people may also notice sudden weight gain and swelling (edema) of ankles or feet. Consult your doctor immediately if you notice any of these side effects.
