Important Safety Information: BLUJEPA/gepotidacin

What is the most important information I should know about BLUJEPA?

BLUJEPA, an antibiotic, can cause serious side effects, including:

changes in electrical activity of your heart called QTc prolongation. BLUJEPA can cause QTc prolongation (also called prolonged QTc interval) that can lead to serious heart rhythm problems, including Torsades de Pointes. There may be changes in your heartbeat (a fast or irregular heartbeat).

Before starting BLUJEPA, tell your healthcare provider if you:

• or anyone in your family has ever had a heart rhythm problem (problem with heart rate or heartbeat) or QTc prolongation.
• are taking any medicines to treat heart rhythm problems. Using these medicines with BLUJEPA may cause serious side effects. If you are not sure, ask your healthcare provider.
• are taking medicines called moderate or strong CYP3A4 inhibitors. Using these medicines with BLUJEPA may cause serious side effects. If you are not sure, ask your healthcare provider.

Tell your healthcare provider right away if you have any of the following symptoms:

• fast, pounding, or uneven heartbeat
• feeling dizzy
• you lose consciousness (pass out)
• feeling lightheaded
• feeling faint
• an increase of a certain chemical in your nervous system (cholinergic effects). BLUJEPA can cause an increase of a certain chemical in your nervous system, which may cause the following symptoms:
  • diarrhea
  • vomiting
  • fainting
  • trouble saying words clearly
  • muscle spasms
  • nausea
  • more saliva in the mouth
  • more sweating
  • stomach pain

Call your healthcare provider right away if you have trouble saying words clearly, have shortness of breath, or if you faint. These symptoms may be cholinergic effects of BLUJEPA.

The increased chemical in your nervous system can also be connected to other symptoms. Call your healthcare provider right away if you have any of these additional symptoms:

• irregular heartbeat (heart block)
• slow heartbeat (bradycardia)
• seizures
• fainting
• chest tightness causing difficulty breathing
• allergic reactions. Allergic reactions can happen in people who take BLUJEPA, including a severe allergic reaction called anaphylaxis. Stop taking BLUJEPA and get medical help right away if you have any symptoms of a severe allergic reaction, including:
  • hives
  • feeling faint or dizzy
  • rash
  • swelling of your lips, tongue, or throat
• diarrhea. Diarrhea is a common side effect caused by antibiotics including BLUJEPA. The diarrhea may happen at the beginning of your treatment with BLUJEPA and usually stops after the antibiotic is stopped. In most cases, the diarrhea will go away without treatment. In some cases, diarrhea may be caused by Clostridioides difficile infection (CDI). CDI is a severe infection of the intestines (bowels) that can happen up to 2 months after finishing treatment with antibiotic medicines, including BLUJEPA. CDI can be life-threatening and can lead to death. Do not take medicines to treat diarrhea without first checking with your healthcare provider. Call your healthcare provider right away if you have the following symptoms:
  • stomach cramps
  • fever
  • watery diarrhea
  • diarrhea that does not go away
  • bloody stools
