• Respiratory tract infections.
• Long-term or recurrent ear or sinus infections.
• Urinary tract infections.
• Male and female genital tract infections.
• Gastrointestinal and intrabdominal infections.
• Skin and soft tissue infections.
• Bone and joint infections.
• Prevention of infections caused by the bacteriaNeisseria meningitidis.
• Exposure to carbuncle by inhalation.

Ciprofloxacin may be used to treat patients with low white blood cell count (neutropenia) who have suspected bacterial fever.

In cases of severe infection or infection caused by multiple types of bacteria, additional antibiotic treatment may be administered in addition to Ciprofloxacino Alter.

Children and adolescents

Ciprofloxacino Alter is used in children and adolescents, under specialized medical supervision, to treat the following bacterial infections:

• Pulmonary and bronchial infections in children and adolescents with cystic fibrosis.
• Complicated urinary tract infections, including kidney infections (pyelonephritis).
• Exposure to carbuncle by inhalation.

This medication may also be used to treat severe infections in children and adolescents when necessary.

Warnings and precautions

Before starting to take this medication

You should not take fluoroquinolone or quinolone antibacterial medications, including Ciprofloxacino Alter, if you have had a severe reaction to a quinolone or fluoroquinolone in the past. If this is the case, you should inform your doctor as soon as possible.

Consult your doctor before starting to take this medication

• If you have ever had kidney problems, as your treatment may need to be adjusted.
• If you suffer from epilepsy or other neurological conditions.
• If you have a history of tendon problems during previous antibiotic treatment with Ciprofloxacino Alter.
• If you suffer from myasthenia gravis (a type of muscle weakness).
• If you have heart problems. You should exercise caution when taking ciprofloxacin if you were born with or have a family history of prolonged QT interval (seen on the ECG, heart electrical recording), have electrolyte imbalances in the blood (especially low levels of potassium and magnesium), have a slow heart rate (bradycardia), have a fragile heart (cardiac arrest), have a history of heart attacks (myocardial infarction), you are a woman or an elderly person, or you are taking other medications that cause abnormal ECG changes (see section 2: Taking Ciprofloxacino Alter with other medications).
• If you have been diagnosed with an enlarged or "bulge" of a large blood vessel (aortic aneurysm or peripheral large vessel aneurysm).
• If you have had a previous episode of aortic dissection (tear in the aorta wall).
• If you have been diagnosed with heart valve insufficiency (regurgitation of heart valves).
• If 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, giant cell arteritis, Behçet's disease, hypertension, known atherosclerosis, rheumatoid arthritis (a joint disease) or endocarditis (a heart infection)).

For the treatment of some genital tract infections, your doctor may prescribe another antibiotic in addition to ciprofloxacin. If there is no improvement in symptoms after 3 days of treatment, please consult your doctor.

During treatment with this medication

Inform your doctor immediately if any of the following situations occur. Your doctor will decide whether to discontinue treatment.

• Severe and sudden allergic reaction(anaphylactic reaction, angioedema). There is a reduced possibility that, even with the first dose, you may experience a severe allergic reaction, with the following symptoms: chest tightness, dizziness, nausea or fainting, or experiencing dizziness when standing up. If this happens, do not take any more Ciprofloxacino Alter and contact your doctor immediately.
• Severe, incapacitating, and potentially irreversible adverse effectsThe fluoroquinolone or quinolone antibacterial medications, including Ciprofloxacino Alter, have been associated with rare but severe adverse effects, some of which were of long duration (persistent for months or years), incapacitating, or potentially irreversible. This includes tendon pain, muscle and joint pain in the upper and lower limbs, difficulty walking, abnormal sensations such as pinching, tingling, numbness, or burning (paresthesia), sensory disorders such as decreased vision, taste, smell, and hearing, depression, decreased memory, intense fatigue, and severe sleep disorders.
• If you experience any of these adverse effects after taking Ciprofloxacino Alter, contact your doctor immediately before continuing treatment. You and your doctor will decide whether to continue or discontinue treatment, considering also the use of another class of antibiotic.
• In rare cases, you may experiencejoint pain and swelling, and inflammation or rupture of tendons. The risk is higher if you are an elderly person (over 60 years old), have received an organ transplant, have kidney problems, or are taking corticosteroids. Tendon inflammation and rupture can occur within the first 48 hours of treatment and even several months after discontinuing Ciprofloxacino Alter treatment. If you experience any pain or swelling in a tendon (e.g., in the ankle, wrist, elbow, shoulder, or knee), stop taking Ciprofloxacino Alter, contact your doctor, and keep the affected area at rest. Avoid any unnecessary exercise, as this may increase the risk of tendon rupture.
• If you experience asevere and sudden abdominal, chest, or back pain, which may be symptoms of aortic dissection or aneurysm, go to the emergency room immediately.
• If you start experiencing sudden shortness of breath, especially when lying down, or if you notice swelling in your ankles, feet, or abdomen, or if you experience palpitations (rapid and irregular heartbeat), inform your doctor immediately.
• If you suffer fromepilepsyor anotherneurological condition, such as ischemia or cerebral infarction, you may experience adverse effects associated with the central nervous system. If this occurs, stop taking this medication and contact your doctor immediately.
• In rare cases, you may experience symptoms ofnerve damage (neuropathy), such as pain, burning, tingling, numbness, and/or weakness, especially in your feet and legs or hands and arms. If this happens, stop taking Ciprofloxacino Alter and inform your doctor immediately to prevent the development of a potentially irreversible disorder.
• You may experiencepsychiatric reactionsfor the first time when taking this medication. If you suffer fromdepressionorpsychosis, your symptoms may worsen with treatment using this medication. In rare cases, depression or psychosis may progress to suicidal thoughts, attempts, or completed suicide. If this occurs, stop taking this medication and contact your doctor immediately.
• Quinolone antibiotics can cause anincrease in your blood sugar levelsabove normal levels (hyperglycemia), or a decrease in your blood sugar levels below normal levels, which in severe cases may cause a loss of consciousness (hypoglycemic coma) (see section 4). This is important for people with diabetes. If you have diabetes, your blood sugar levels should be carefully controlled.
• You may developdiarrheawhile taking antibiotics, including this medication, or even several weeks after stopping them. If diarrhea becomes intense or persistent, or if you notice that your stools contain blood or mucus, discontinue taking this medication immediately, as this may put your life at risk. Do not take medications that slow down or delay bowel movements and consult your doctor.
• While taking this medication, inform your doctor or laboratory personnel if you need to undergo ablood or urine test.

Advice / Medical Education

Antibiotics are used to cure bacterial infections. They are not effective against viral infections.

If your doctor has prescribed antibiotics, you need them specifically for your current illness. Despite antibiotics, some bacteria may survive or grow. This phenomenon is known as resistance: some antibiotic treatments become ineffective.

Abuse of antibiotics increases resistance. You can even help bacteria become more resistant and, therefore, delay your recovery or reduce the effectiveness of antibiotics if you do not respect:

• the dose
• the program
• the duration of treatment

As a result, in order to maintain the effectiveness of this medication:

1. Use antibiotics only when prescribed.
2. Follow the prescription strictly.
3. Do not reuse an antibiotic without a doctor's prescription, even if you want to treat a similar illness.
4. Never give your antibiotic to someone else; it may not be adapted to their illness.
5. After completing a treatment, return all unused medications to the pharmacy to ensure they are disposed of correctly.
