Humalog Information:

What is Humalog?

Humalog, or insulin lispro, is a short-acting or fast-acting insulin used to treat patients with type 1 and type 2 diabetes. Insulin is a hormone that is naturally produced by the body to convert glucose into energy. It also helps the body to store energy.  Humalog may be used in conjunction with long-acting insulin to control blood sugar levels. 

How do I take Humalog?

Before filling a prescription, print your free Humalog coupon from HelpRx or apply for Humalog patient assistance through Lilly TruAssist. You can inject Humalog using syringes or Kwikpens. Your physician will advise you which method will work best for your symptoms. For patients who need very small doses, you have the option of using HumaPen LUXURA HD. Make sure your Humalog is not cloudy, and does not have any floating particles. Do not take Humalog 75/25 or Humalog 50/50 in a pump. Do not mix your insulin with other fluid. You can select from a number of possible injection sites, which you must rotate for each injection. Take Humalog within 15 minutes before eating a meal, or directly after. 

Before taking Humalog, tell your doctor if:

Before taking Humalog, make sure your doctor is aware of all your medical conditions, including liver, kidney, or heart problems. Also alert your physician if you are pregnant or breastfeeding. Be sure to review with your doctor all the prescription and non-prescription medicines you take, especially TZDs (thiazolidinediones). Some drug combinations with Humalog can be dangerous. 

What are the possible side effects of taking Humalog?

The most common side effect of Humalog is low blood sugar. Learn to recognize symptoms of low blood sugar and have a plan of action. Low potassium is also possible, as well as weight gain, local allergic reactions, and severe allergic reactions. 

What if I forget to take a dose of Humalog?

If you miss a dose of Humalog, you run the risk of developing hyperglycemia. Hyperglycemia can lead to loss of consciousness, coma, and death. If you experience hyperglycemia, consume a source of sugar as soon as possible. If you experience severe hyperglycemia symptoms, seek immediate medical attention. 

How do I store Humalog?

Store Humalog in the refrigerator. Check to make sure you use it before the expiration date listed on the carton and label. Humalog should be stored away from light and heat. Do not freeze Humalog, and don’t use Humalog that has been frozen at any point. Keep open vials at room temperature or in a refrigerator. Also keep open or prefilled cartridges at room temperature. Once opened, Humalog vials, prefilled pens, and cartridges should be thrown away after 28 days.

What happens if I overdose on Humalog?

Taking too much Humalog can result in both hypoglycemia and hypekalemia. Hypoglycemia can be treated with oral doses of glucose. Hypekalemia, a condition caused by too much potassium, can be treated with subcutaneous glucose. If you have mild low blood-sugar, consume a quick source of sugar. If you have a whole body rash, seizures, trouble breathing, a fast heartbeat, or are sweating, call 911 to get medical help right away.



Discuss switching to Humalog with your physician before getting your prescription. Do not take Humalog if you suffer from hypoglycemia, a condition that occurs when blood sugar is too low. You should also not take Humalog if you are allergic to insulin lispro or any of the other components of Humalog. If you take TZDs [thiazolidinediones] at the same time as Humalog, you will put yourself at risk for heart failure.
