Read this leaflet carefully beforeyou receivethis medicine, because it contains important information for you.

• Keep this leaflet, as you may need to read it again.
• If you have any questions, consult your doctor, pharmacist or nurse.
• This medicine has been prescribed for you only, and you must not give it to others even if they have the same symptoms as you, as it may harm them.
• If you experience any side effects, consult your doctor, pharmacist or nurse, even if they are not listed in this leaflet. See section 4.

Quofenix is an antibiotic that contains the active ingredient delafloxacino. It belongs to a group of medications called fluoroquinolones.

It is used for the treatment in adults of severe and short-duration infections caused by certain bacteria, when usual antibiotics cannot be used or have not been effective:

• skin and subcutaneous tissue infections
• lung infection called "pneumonia"

It blocks the enzymes that bacteria need to copy and repair their DNA. By blocking these enzymes, Quofenix kills the bacteria that cause the infection.

Do not administer Quofenix

• If you are allergic to delafloxacino or any of the other components of this medication (including those listed in section 6).
• If you are allergic to any other fluoroquinolone or quinolone antibiotic.
• If you have ever had a problem with tendons, such as tendinitis, related to treatment with "quinolone-type antibiotics". A tendon is the cord that connects the muscle to the skeleton.
• If you are pregnant, intend to become pregnant, or think you may be pregnant.
• If you are breastfeeding.
• If you are a child or adolescent under the age of 18 years.

Warnings and precautions

Before this medication is administered

Do not administer fluoroquinolone/quinolone antibiotics, including Quofenix, if you have experienced a severe adverse reaction in the past when taking a quinolone or fluoroquinolone. In this case, inform your doctor as soon as possible.

When this medication is administered

• In rare cases, pain and swelling in the joints, inflammation, or tendon rupture may occur. Your risk increases if you are an elderly patient (over 60 years old), have received an organ transplant, have kidney problems, or are being treated with corticosteroids. Tendon inflammation and ruptures can occur within the first 48 hours of treatment and even several months after stopping Quofenix treatment. If you experience any pain or inflammation in a tendon (for example, in the ankle, wrist, elbow, shoulder, or knee), do not administer Quofenix, contact your doctor, and rest the affected area. Avoid any unnecessary exercise, as this may increase the risk of tendon rupture.

• In rare cases, symptoms of nerve damage (neuropathy) such as pain, burning, tingling, numbness, and/or weakness, especially in the feet and legs or hands and arms, may occur. If this happens, do not administer Quofenix, and inform your doctor immediately to prevent the development of a potentially irreversible alteration.

Consult your doctor, pharmacist, or nurse before Quofenix is administered if:

• You have been diagnosed with an enlarged or bulging large blood vessel (aortic aneurysm or large peripheral vessel aneurysm).
• You have had a previous episode of aortic dissection (tear in the aorta wall).
• You have been diagnosed with heart valve insufficiency (regurgitation of heart valves).
• You have a family history of aortic aneurysm or aortic dissection, congenital heart valve disease, or other predisposing risk factors (e.g., Marfan syndrome or Ehlers-Danlos vascular syndrome, Turner syndrome, or Sjögren's syndrome (an autoimmune inflammatory disease), or vascular disorders such as Takayasu arteritis, giant cell arteritis, Behçet's disease, hypertension, or known atherosclerosis, rheumatoid arthritis (a joint disease) or endocarditis (a heart infection)).
• You have had tendon problems during previous treatment with a quinolone or fluoroquinolone antibiotic.
• You have or may have central nervous system problems (e.g., severe cerebral arteriosclerosis, epilepsy) or other risk factors that may increase the risk of seizures (attacks). In these cases, your doctor will consider whether this treatment is the best option for you.
• You have myasthenia gravis (a type of muscle weakness), as symptoms may worsen.
• You have diarrhea, or have had diarrhea when taking antibiotics or up to 2 months after. Contact your doctor immediately if you have diarrhea during or after treatment. Do not take any medication to treat diarrhea without consulting your doctor first.
• You have kidney problems.
• You have had prolonged antibiotic treatment; this may mean you contract another infection caused by other bacteria (superinfection) that cannot be treated with the antibiotic. Consult your doctor if you have any doubts or questions about this and about the use of Quofenix.
• You may have a severe skin reaction, such as blisters or lesions.
• You or a family member has glucose-6-phosphate dehydrogenase deficiency.
• You have diabetes. Fluoroquinolone antibiotics, including Quofenix, may cause blood glucose levels to rise or fall too low. If you have diabetes, you must carefully control your blood glucose levels.

If you experience severe and sudden pain in the abdomen, chest, or back, which may be symptoms of aortic dissection or aneurysm, go immediately to an emergency service. You may be at increased risk if you are receiving systemic corticosteroid treatment.

If you start experiencing sudden onset of shortness of breath, especially when lying down, or if you notice swelling in the ankles, feet, or abdomen, or the onset of palpitations (sensation of rapid or irregular heartbeat), inform your doctor immediately.

Severe, prolonged, incapacitating, and potentially irreversible side effects

Fluoroquinolone/quinolone antibiotics have been associated with very rare but severe side effects, some of which are of long duration (lasting months or years), incapacitating, or potentially irreversible. This includes tendon pain, muscle, and joint pain in the upper and lower extremities, difficulty walking, abnormal sensations such as tingling, numbness, or burning (paresthesia), sensory disorders such as vision, taste, and smell deterioration, and hearing, depression, memory deterioration, severe fatigue, and severe sleep disorders.

If you experience any of these side effects after receiving Quofenix, contact your doctor immediately before continuing treatment. You and your doctor will decide whether to continue treatment, also considering another class of antibiotic.

Children and adolescents

This medication should not be used in children and adolescents, as it has not been sufficiently studied in these groups.

Other medications and Quofenix

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

Quofenix should not be administered with any solution containing substances such as calcium and magnesium through the same intravenous route.

Pregnancy and lactation

Quofenix should not be used if you are pregnant or breastfeeding. Quofenix should not be used in fertile women who do not use effective contraceptive methods.

If you are pregnant or breastfeeding, or think you may be pregnant, consult your doctor before Quofenix is administered.

If you may become pregnant, use effective contraceptive methods during Quofenix treatment.

Driving and operating machinery

Quofenix may cause dizziness and disorientation. Until you know how Quofenix affects you, do not drive, operate machinery, or perform other activities that require mental acuity or coordination.

Quofenix contains cyclodextrins

This medication contains 2480 mg of sodium sulfobutyl beta-cyclodextrin in each vial.

Quofenix contains sodium

This medication contains 175 mg of sodium (main component of cooking salt) in each vial. This is equivalent to 8.8% of the recommended daily maximum sodium intake for an adult.

Quofenix will be administered to you by a nurse or doctor through an infusion (drip) into a vein.

You will receive an infusion of Quofenix, which contains 300 mg of the medication, two times a day for 5 to 14 days for skin infections and 5 to 10 days for pneumonia, as determined by your doctor. Each infusion will last approximately one hour. Your doctor will decide how many days of treatment are needed.

Inform your doctor if you have kidney problems, as you may need to adjust your dosage.

If you have any questions about the use of this medication, ask your doctor.

If you are given more Quofenix than you should

Tell your doctor or nurse immediately if you are concerned that you have been given more Quofenix than you should.

If you forget a dose of Quofenix

Tell your doctor or nurse immediately if you are concerned that you have forgotten a dose.

If you have any other questions about the use of this medication, ask your doctor or nurse.
