Levemir (insulin detemir) is a long-acting insulin used to help control blood sugar levels in people with diabetes. It provides steady, 24-hour blood sugar regulation and is typically used once or twice daily. Levemir Penfill cartridges are designed for use with compatible insulin pens, offering a convenient and precise way to administer insulin.
Benefits:
- Provides long-lasting blood sugar control for up to 24 hours.
- Can be taken once or twice daily, depending on individual needs.
- Reduces the risk of blood sugar fluctuations compared to short-acting insulins.
- Lower risk of weight gain compared to some other long-acting insulins.
- Compatible with Novo Nordisk insulin pens for easy dosing.
Dosage:
- Typically injected once daily or twice daily, as prescribed by a doctor.
- Dose is individualized based on blood sugar levels, lifestyle, and other diabetes medications.
- Must be used with a meal plan and regular blood sugar monitoring.
Warnings and Precautions:
- Not for use in diabetic ketoacidosis (DKA)—use rapid-acting insulin instead.
- May cause low blood sugar (hypoglycemia); monitor regularly.
- Inform your doctor if you have kidney, liver, or heart disease.
- Do not mix with other insulins in the same injection.
- Rotate injection sites to prevent lipodystrophy (skin thickening or lumps).
Usage Instructions:
- Insert the cartridge into a compatible insulin pen.
- Check the insulin—it should be clear and colorless.
- Prime the pen as directed before injecting.
- Inject subcutaneously in the abdomen, thigh, or upper arm.
- Rotate injection sites to avoid skin irritation.
Storage Information:
- Unopened cartridges: Store in the refrigerator (2°C to 8°C); do not freeze.
- In-use cartridges: Store at room temperature (below 30°C) for up to 42 days.
- Keep away from direct heat and sunlight.
- Do not use if expired or if the insulin appears cloudy.
Common Side Effects:
- Low blood sugar (dizziness, sweating, shakiness).
- Injection site reactions (redness, swelling, itching).
- Mild weight gain.
- Skin thickening or lumps at injection sites.
- Swelling in hands or feet (fluid retention).

Dorothy (. 
USHorrible Service
I have been trying to get the insulin for my dog for over a month. It is absolutely ridiculous that it has taken so long to get to get it. One shipment did arrive 2 weeks ago, but it was hot. There was minimal Ice packing did nothing to protect it during transit. It has taken more than two weeks and several calls and emails to receive a replacement. In fact I still have not received it. Our vet has contacted you several times stating the critical need, but to no avail. Its very unfortunate that there is such little care and concern for my dog's life from your company.

Terrible Customer Services
Would love to tell you but ever got delivered to the correct address!!! Phoned to place my order as had had a terrible service previous time (they completely made up what my prescription said so reduced order to 1 box instead of 3 ordered) this time wanted to make sure they understood how to read the same prescription but appears when you phone them they don’t have the same info as the online system so they sent it to an address I lived at 4 years ago and then had the audacity to say it must have been a mix up!! Can’t be right as have moved twice since that address!!!! So now am waiting for new insulin to arrive which they still have to process the same way so could take 10 days and only have enough insulin to last about 4, don’t worry they informed me just go to a local pharmacy and get!!!! Hello I don’t have a prescription you do and to get a new one is a complete hassle….. Whole thing has been a nightmare!!!

Shambles
The item is fine, your processing of my order, your lack of understanding of how to read a prescription which will now cost me extra money is appalling and your dealing with my complaint which is now 2 weeks outstanding is extremely poor
