Humalog 50/50 is a combination insulin made up of an intermediate-acting insulin (lispro protamine) and a fast-acting insulin (lispro). Since it's a combination insulin, it's not as easy to adjust your dose compared to single-ingredient insulins.

Check your blood sugar levels regularly while using Humalog 50/50 to make sure that this medication is working correctly. Talk with your healthcare provider about what blood sugar is too high or low for you.
Whether you're using the Humalog 50/50 vials or pens, gently roll the vial or pen in between your hands about 10 times. Then flip the vial or pen up and down (invert) about 10 times. This mixing technique helps to make sure you get the right dose of medication.
Once you've mixed the vials or pens, the Humalog 50/50 solution should look cloudy and milky in color. Don't use Humalog 50/50 if the solution looks clear, has clumps, or if there's white particles sitting at the bottom of the container.
After mixing Humalog 50/50, inject your dose shortly after. If you wait to inject your dose, you'll need to mix the insulin again.
Inject Humalog 50/50 15 minutes before you eat a meal under the skin (subcutaneously) of your stomach area, buttocks, upper legs, or upper arms.
Rotate injection sites to prevent hard lumps from forming.
Never inject Humalog 50/50 into your vein (intravenously) or muscle (intramuscularly) or use it in an insulin infusion pump.
Read the package insert for troubleshooting tips with the Humalog 50/50 pen. If you're still having trouble giving yourself the medication, talk to your provider or pharmacist.
Humalog 50/50 can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Never share Humalog 50/50 pens, syringes, or needles with anyone else, even if you change out the needle. Sharing Humalog 50/50 with someone puts you at risk of getting very dangerous diseases and infections.
Risk factors: Changes in diet and exercise | Drinking alcohol | Taking other medications for diabetes | Age 65 or older | Liver or kidney problems | Not injecting insulin correctly
Humalog 50/50 alone or together with other diabetic medications can cause low blood sugar. Very low blood sugar can be life-threatening. Symptoms of low blood sugar include feeling shaky, being nervous or anxious, fast heartbeat, sweating or body chills, confusion, feeling sleepy, weakness or low energy, and excessive hunger. This can happen suddenly and can appear differently for each person. Make sure you know how to treat low blood sugar before using this medication. It's best to carry with you some form of sugar at all times while you are taking this medication because you can use these to raise your blood sugar if it becomes too low. Some examples of fast-acting sugars include: 3-4 glucose (sugar) tablets, 6-8 pieces of hard candy, or one-half cup of fruit juice.
Risk factors: Taking laxatives | Taking medications that increase urination
Humalog 50/50 can lower levels of potassium in your blood, which can be dangerous. You're at higher risk of this if you're already taking medications that lower your potassium. Your provider will check your potassium levels regularly and might give you medications to keep your potassium in the normal range. Symptoms of low potassium levels include weakness, muscle cramps or twitches, digestive problems, abnormal heartbeats, or kidney problems.
Risk factors: Taking PPAR-gamma agonists | Heart failure
Taking Humalog 50/50 with thiazolidinediones (like pioglitazone or rosiglitazone), which are called PPAR-gamma agonists, can cause your body to hold onto fluid. This can be especially dangerous if you have heart failure because additional fluid can worsen your heart failure. Make sure your provider knows about your complete medical history before starting this medication.
The dose of Humalog 50/50 will be different for every person. The amount you need will depend on your blood sugar level, your weight, and how responsive you are to insulin. Please follow the directions from your provider carefully.
Humalog 50/50 is typically injected under the skin twice a day (with each dose meant to cover 2 meals or a meal and a snack). The medication should be injected within 15 minutes before a meal.
Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
