KIRSTY

CAN

With Kirsty™, a biosimilar option that works like NovoLog (insulin aspart), more is possible in managing diabetes.1

Serving Similarity You Can Trust

KIRSTY is a rapid-acting insulin biosimilar that’s interchangeable with NovoLog from a trusted name in insulin, Biocon Biologics.1,2

What is a biosimilar?

A biosimilar is a nearly identical copy of an existing medicine. It works in the same way and is as safe and effective, so you can be sure to receive the same care as with the original approved medicine.3

What is an interchangeable biosimilar?

An interchangeable biosimilar meets the same high standards of biosimilarity and can be safely switched from the original approved medicine to a biosimilar by a pharmacist without doctor approval—helping more people get the medicine they need.*3

*Subject to state pharmacy laws.

IMPORTANT SAFETY INFORMATION

Do not share your KIRSTY Prefilled Pen with other people, even if the needle has been changed. You may give other people a serious infection, or get a serious infection from them.

Do not take KIRSTY if you:

  • are having an episode of low blood sugar (hypoglycemia).
  • have an allergy to insulin aspart products or any of the ingredients in KIRSTY.

Before taking KIRSTY, tell your healthcare provider about all your medical conditions, including if you are:

  • pregnant, planning to become pregnant, or are breastfeeding.
  • taking new prescription or over-the-counter medicines, vitamins, or herbal supplements.

Before you start taking KIRSTY, talk to your healthcare provider about low blood sugar and how to manage it.

KIRSTY starts acting fast. You should eat a meal within 5 to 10 minutes after you take your dose of KIRSTY.

Check your blood sugar levels.

Do not reuse or share your needles with other people.

KIRSTY can be injected under the skin (subcutaneously) of your stomach area (abdomen), buttocks, upper legs (thighs) or upper arms, or by continuous infusion under the skin (subcutaneously) through an insulin pump into an area of your body recommended in the instructions that come with your insulin pump.

Change (rotate) your injection sites within the area you choose with each dose to reduce your risk of getting lipodystrophy (pits in skin or thickened skin) and localized cutaneous amyloidosis (skin with lumps) at the injection sites. Do not use in the exact same spot for each injection, inject where the skin has pits, is thickened or has lumps. Do not inject where the skin is tender, bruised, scaly, hard, into scars or damaged skin.

While taking KIRSTY do not drive or operate heavy machinery, until you know how KIRSTY affects you. You should not drink alcohol or use prescription or over-the-counter medicines that contain alcohol.

KIRSTY may cause serious side effects that can lead to death, including, low blood sugar (hypoglycemia). Signs and symptoms that may indicate low blood sugar include dizziness or light-headedness, blurred vision, anxiety, irritability or mood changes, sweating, slurred speech, hunger, confusion, shakiness, headache or fast heartbeat.

Your insulin dose may need to change because of change in level of physical activity or exercise, increased stress, change in diet, weight gain or loss or illness

Other common side effects of KIRSTY may include low potassium in your blood (hypokalemia), reactions at the injection site, itching, rash, serious allergic reactions (whole body reactions), skin thickening or pits at the injection site (lipodystrophy), weight gain, and swelling of your hands and feet.

Get emergency medical help if you have trouble breathing, shortness of breath, fast heartbeat, swelling of your face, tongue, or throat, sweating, extreme drowsiness, dizziness, confusion.

These are not all the possible side effects of KIRSTY. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
