How will I take this drug?

You only need to get the drug once. It is given though an intravenous (IV) infusion. This means that a nurse will put a small needle into your arm to give you the drug slowly over about 1 hour. The treatment is usually given at a hospital, clinic, or infusion center.

Getting any medicine through an IV can cause side effects in the area where the needle went into the skin. These may include:

  • Pain that lasts a short time during the infusion.

  • Bleeding, bruising, swelling, or soreness.

  • Infection.

Is bamlanivimab safe?

Scientists are not sure yet if this medicine is safe. It is still being studied. Benefits and risks are still unclear.

Based on the results of the research so far, the FDA has found that the drug may have more benefits than risks in treating COVID-19 during the pandemic. Because of this, the Food and Drug Administration (FDA) has given a temporary Emergency Use Authorization. This allows doctors to use bamlanivimab with certain patients.

What are the side effects?

Side effects can range from mild to serious. These may include:

  • Wheezing (noisy breathing that may sound like whistling) or trouble breathing.

  • Swollen lips, face, or throat.

  • Flu-like symptoms (fever, sweating, chills, cough, sore throat, headache, or muscle pain).

  • Upset stomach (nausea, vomiting, or diarrhea).

  • Itching, swelling, rash, or hives.

  • Dizziness or low blood pressure.

  • Changes in your heartbeat.

Tell your doctor or nurse right away if you have any side effects during or after your infusion. Some of these side effects may be signs of a serious allergic reaction.

You can also report side effects to FDA MedWatch at or by calling 1-800-FDA-1088.

What should I tell my healthcare provider before I receive bamlanivimab?

Tell your healthcare provider about all of your medical conditions, including if you:

  • Have any allergies.

  • Are pregnant or plan to become pregnant.

  • Are breastfeeding or plan to breastfeed.

  • Have any serious illnesses.

  • Are taking any medicines (prescription, over-the-counter, vitamins, and herbal products).

What if I am pregnant or breastfeeding?

There is limited experience treating pregnant women or breastfeeding mothers with bamlanivimab. For a mother and unborn baby, the benefit of receiving bamlanivimab may be greater than the risk from the treatment. If you are pregnant or breastfeeding, discuss your options and specific situation with your healthcare provider.
