Semglee Pen (Subcutaneous)
Generic name: insulin glargine-yfgn, recombinant
Brand names: Semglee, Semglee Pen
Uses for Semglee Pen
Insulin glargine-yfgn injection is a long-acting insulin that works slowly, over about 24 hours. Insulin is one of several hormones that help the body convert food into energy. It does this by using the glucose (sugar) in the blood for quick energy. Insulin also helps us store energy for later use. When you have diabetes mellitus, your body cannot produce enough insulin or does not use insulin properly. This leads to too much sugar in your blood. Like other insulins, insulin glargine-yfgn helps keep your blood sugar level close to normal. You may need to use insulin glargine-yfgn along with another type of insulin or an oral diabetes medicine to manage your blood sugar.
This medicine is available only with your doctor's prescription.

Precautions while using Semglee Pen
Never share insulin pens or cartridges with anyone for any reason. It is not safe for one pen to be used by more than one person. Sharing needles or pens can lead to the spread of hepatitis viruses, HIV, or other infections that can be transmitted through blood.
Your doctor will want to monitor your progress during regular visits, especially in the first few weeks you use this medicine. Blood tests may be necessary to check for side effects.
It is very important to carefully follow any instructions from your health care team regarding:
- Alcohol—Drinking alcohol may lead to severe low blood sugar. Talk about this with your health care team.
- Other medicines—Do not take any other medicines while using insulin glargine-yfgn unless your doctor has discussed them with you. This includes over-the-counter medicines like aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus issues.
- Counseling—Other family members should learn how to prevent or help with side effects if they happen. Also, patients with diabetes may need special counseling about changes in medicine dosing due to lifestyle changes, like changes in exercise and diet. Additionally, counseling on contraception and pregnancy may be necessary due to potential issues for patients with diabetes during pregnancy.
- Travel—Keep a recent prescription and your medical history with you. Be ready for emergencies as you normally would. Adjust for different time zones and try to keep your meal times as close as possible to your usual schedule.
In case of emergency—There may be times when you need emergency assistance for a diabetes-related issue. Be prepared for these situations. It is a good idea to:
- Wear a medical identification (ID) bracelet or necklace at all times. Also, carry an ID card in your wallet or purse that states you have diabetes and lists all of your medicines.
- Keep an extra supply of insulin glargine-yfgn and syringes or injection devices on hand in case of high blood sugar.
- Have quick-acting sugar available to treat low blood sugar.
- Have a glucagon kit and a syringe and needle ready in case of severe low blood sugar. Regularly check and replace any expired kits.
Too much insulin glargine-yfgn can cause hypoglycemia (low blood sugar). Low blood sugar can also happen if you use insulin glargine-yfgn with another diabetes medicine, change your insulin regimen (e.g., insulin strength, type of insulin, injection site), delay or skip a meal or snack, exercise more than usual, or drink alcohol. Symptoms of low blood sugar should be treated before they lead to unconsciousness (passing out). Different people may experience different symptoms of low blood sugar. It is important to recognize which symptoms you usually have so you can treat it quickly.
Symptoms of low blood sugar include anxiety, behavior changes similar to intoxication, blurred vision, cold sweats, confusion, difficulty thinking, dizziness or lightheadedness, drowsiness, excessive hunger, fast heartbeat, headache, irritability or unusual behavior, nervousness, nightmares, restless sleep, shakiness, slurred speech, and tingling in the hands, feet, lips, or tongue.
If you experience symptoms of low blood sugar, consume glucose tablets or gel, corn syrup, honey, or sugar cubes, or drink fruit juice, regular soft drink, or sugar dissolved in water to relieve the symptoms. Also, check your blood for low blood sugar. If symptoms do not improve, seek medical help immediately. Someone should call for emergency assistance if severe symptoms like convulsions (seizures) or unconsciousness occur. Have a glucagon kit available, along with a syringe and needle, and know how to use it. Other members of your household should also know how to use it.
This medicine may cause dizziness or drowsiness. Do not drive or perform any activities that could be dangerous until you know how this medicine affects you.
Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your diabetes medicine, change your insulin regimen, overeat or do not follow your meal plan, have a fever or infection, or do not exercise as much as usual.
Symptoms of high blood sugar include blurred vision, drowsiness, dry mouth, flushed dry skin, a fruity odor on your breath, increased urination, ketones in the urine, loss of appetite, stomachache, nausea, or vomiting, tiredness, rapid and deep breathing, unconsciousness, and unusual thirst.
If you notice symptoms of high blood sugar, check your blood sugar level and then call your doctor for instructions.
This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Contact your doctor immediately if you experience a rash, itching, difficulty breathing, trouble swallowing, or any swelling of your hands, face, or mouth while using this medicine.
This medicine may lower the potassium levels in your blood. Do not use medicines, supplements, or salt substitutes that contain potassium unless you have discussed this with your doctor.
Using this medicine along with other diabetes medications (e.g., thiazolidinedione [TZD] medicine) may lead to serious heart problems or edema (fluid retention). Contact your doctor right away if you experience rapid weight gain, chest pain or discomfort, extreme tiredness or weakness, difficulty breathing, an irregular heartbeat, or significant swelling of the hands, wrists, ankles, or feet.

Proper use of Semglee Pen
A nurse or other trained health professional may give you this medicine. You may also be taught how to give your medicine at home. This medicine is given as a shot under the skin of your stomach, thigh, or upper arm.
Always check the label before use, to make sure you have the correct type of insulin. Do not change the brand, type, or concentration unless your doctor tells you to. If you use a pump or other device, make sure the insulin is made for that device.
Always double-check both the concentration (strength) of your insulin and your dose. Concentration and dose are not the same. The dose is how many units of insulin you will use. The concentration tells how many units of insulin are in each milliliter (mL), such as 100 units/mL (U-100), but this does not mean you will use 100 units at a time.
Each package of Semglee® contains a patient information sheet. Read this sheet carefully and make sure you understand:
- How to prepare the medicine.
- How to inject the medicine.
- How to dispose of syringes, needles, and injection devices.
If you use this medicine at home, you will be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas. Do not use the exact same spot for each injection. This will help prevent skin problems from the injections.
Since this medicine lowers the blood glucose over 24 hours, it should be injected once daily at bedtime. It is best to use it at about the same time every day.
This medicine should be clear and colorless before you use it. Do not use it if it looks cloudy colored, or has particles in it. Do not shake the vial. Do not mix this medicine with any other insulin or with water.
Follow carefully the special meal plan your doctor gave you. This is the most important part of controlling your condition, and is necessary if the medicine is to work properly. Also, exercise regularly and test for sugar in your blood or urine as directed.
Dosing
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
