Read this package insert carefully before starting to take this medication, as it contains important information for you.

• Keep this package insert, as you may need to refer to it again.
• If you have any questions, consult your doctor, pharmacist, or nurse.
• This medication has been prescribed for you only, and you should not give it to others who have the same symptoms as you, as it may harm them.

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-term 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 take Quofenix

• If you are allergic to delafloxacino or any of the other components of this medication (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 taking this medication

Do not take fluoroquinolone or quinolone antibiotics, including Quofenix, if you have had a severe reaction in the past to taking a quinolone or fluoroquinolone. In this case, inform your doctor as soon as possible.

While taking this medication

• In rare cases, you may experience pain and swelling in the joints, inflammation, or rupture of tendons. 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. At the first sign of tendon pain or inflammation (for example, in the ankle, wrist, elbow, shoulder, or knee), stop taking Quofenix, contact your doctor, and rest the affected area. Avoid unnecessary exercise, as this may increase the risk of tendon rupture.

• In rare cases, you may experience symptoms of nerve damage (neuropathy) such as pain, burning, tingling, numbness, and/or weakness, especially in the feet and legs or hands and arms. If this happens, stop taking Quofenix and inform your doctor immediately to prevent the development of a potentially irreversible alteration.

Consult your doctor, pharmacist, or nurse before taking Quofenix if:

• You have been diagnosed with a large artery aneurysm or peripheral artery aneurysm.
• You have had a tear in the wall of the aorta (the main artery of the heart) known as aortic dissection.
• 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 risk factors or predisposing conditions (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 or 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-type 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 taking Quofenix, contact your doctor immediately before continuing treatment. You and your doctor will decide whether to continue treatment, considering also an antibiotic of another class.

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