1. What Ciprofloxacin SUN tablets are and what they are used for
Ciprofloxacin tablets contain the active substance ciprofloxacin. Ciprofloxacin is an antibiotic belonging to the fluoroquinolone family. Ciprofloxacin works by killing the bacteria that cause infections. It only works with specific strains of bacteria.

Antibiotics are used to treat bacterial infections and are not effective against viral infections such as the flu or the common cold.
It is essential to follow the instructions regarding dosage, administration interval, and treatment duration indicated by your doctor.
Do not store or reuse this medication. If you have any leftover antibiotic after completing treatment, return it to the pharmacy for proper disposal. Do not throw away medications down the drain or in the trash.
Adults
Ciprofloxacin tablets are used in adults to treat the following bacterial infections:
- respiratory tract infections
- long-term or recurrent ear or sinus infections
- urinary tract infections
- male and female genital tract infections
- gastrointestinal and intra-abdominal infections
- skin and soft tissue infections
- bone and joint infections
- prevention of infections caused by the bacteria Neisseria meningitidis
- Inhalation anthrax
Ciprofloxacin may be used in the treatment of patients with a low count of a type of white blood cell (neutropenia) who have fever suspected to be due to a bacterial infection.
In case you suffer from a severe infection or if the infection is caused by more than one type of bacteria, you may be given additional antibiotic treatment, in addition to Ciprofloxacin tablets.
Children and Adolescents
Ciprofloxacin tablets are used in children and adolescents, under specialized medical supervision, to treat the following bacterial infections:
- lung and bronchial infections in children and adolescents with cystic fibrosis
- complicated urinary tract infections, including infections that have reached the kidneys (pyelonephritis)
- Inhalation anthrax
Ciprofloxacin may also be used to treat severe infections in children and adolescents when deemed necessary.
2. What you need to know before taking Ciprofloxacin SUN
Do not take Ciprofloxacin SUN:
- if you are allergic to ciprofloxacin, other quinolones, or any of the other components of this medication (listed in section 6).
- if you are taking tizanidine (see section 2: Taking Ciprofloxacin tablets with other medications)
Warnings and Precautions
Before taking this medication
You should not take fluoroquinolone antibacterial medicines, including Ciprofloxacin, if you have previously experienced a severe side effect with a fluoroquinolone or quinolone. If this is the case, inform your doctor as soon as possible
Consult your doctor or pharmacist before starting to take Ciprofloxacin tablets:
- if you have been diagnosed with an enlargement or a "bulge" of a large blood vessel (aortic aneurysm or large peripheral vessel aneurysm).
- if you have had a previous episode of aortic dissection (tear in the aortic wall).
- 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., connective tissue disorders such as 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, high blood pressure, or atherosclerosis).
- if you have 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 treatment with antibiotics like Ciprofloxacin tablets.
- if you are diabetic, as you may be at risk of hypoglycemia with ciprofloxacin.
- if you have myasthenia gravis (a type of muscle weakness), as your symptoms may worsen.
- if you have heart problems. Caution should be exercised when administering ciprofloxacin if you have been born with or have a family history of prolonged QT interval (seen on ECG, electrical recording of the heart), have an electrolyte imbalance (especially low potassium and magnesium levels in the blood), have a very slow heart rate (known as bradycardia), have a delicate heart (falloccardiac), have a history of heart attacks (myocardial infarction), are a woman, an elderly patient, or are taking other medications that result in abnormal ECG changes (see section 2).
- if you or a family member has a deficiency of glucose-6-phosphate dehydrogenase (G6PD), as you may be at risk of anemia when taking ciprofloxacin.
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.
While taking Ciprofloxacin SUN
Inform your doctor immediately if any of the following situations occur while taking Ciprofloxacin SUN. Your doctor will decide whether it is necessary to interrupt treatment with Ciprofloxacin.
- Severe and sudden allergic reaction(anaphylactic reaction or shock, 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, feeling of dizziness, nausea, or fainting, or experiencing dizziness when standing up. If this happens, do not take any more Ciprofloxacin and contact your doctor immediately.
- In rare cases, joint pain and swelling and tendon inflammation or rupturemay occur. The risk is higher if you are an elderly person (over 60 years old), have received an organ transplant, have kidney problems, or are being treated with corticosteroids. Tendon inflammation and rupture can occur within the first 48 hours of treatment and even several months after stopping treatment with ciprofloxacin. At the first sign of pain or inflammation of a tendon (e.g., in the ankle, wrist, elbow, shoulder, or knee), stop taking ciprofloxacin, contact your doctor, and rest the affected area. Avoid any unnecessary exercise, as it may increase the risk of tendon rupture.
- If you suffer from epilepsyor other neurological conditions, such as cerebral ischemia or infarction, you may experience side effects associated with the central nervous system. If this occurs, stop taking Ciprofloxacin and contact your doctor immediately.
- If you experience a sudden and severe pain in the abdomen, chest, or back, which may be symptoms of aortic dissection or aneurysm, go to the emergency room immediately. The risk may increase if you are receiving systemic corticosteroid treatment.
- If you start to experience sudden shortness of breath, especially when lying down, or if you notice swelling in your ankles, feet, or abdomen, or the appearance of heart palpitations (feeling of rapid or irregular heartbeat), inform your doctor immediately.
- You may experience psychiatric reactionswhen taking Ciprofloxacin for the first time. If you suffer from depressionor psychosis, your symptoms may worsen with treatment with Ciprofloxacin tablets. In rare cases, depression or psychosis may progress to suicidal thoughts, attempted suicide, or completed suicide. If this occurs, stop taking Ciprofloxacin and contact your doctor immediately.
- 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 ciprofloxacin tablets and inform your doctor immediately to avoid the development of a potentially irreversible condition.
- Severe, disabling, and potentially irreversible side effects. Fluoroquinolone or quinolone antibacterial medicines, including ciprofloxacin, have been associated with very rare but serious side effects, some of which were long-lasting (persistent for months or years), disabling, or potentially irreversible. These include tendon pain, muscle and joint pain in the upper and lower limbs, difficulty walking, abnormal sensations such as pins and needles, tingling, numbness, or burning, sensory disorders such as decreased vision, taste, smell, or hearing, depression, decreased memory, intense fatigue, and severe sleep disorders.
If you experience any of these side effects after taking ciprofloxacin, contact your doctor immediately before continuing treatment. You and your doctor will decide whether to continue or not, considering the use of an antibiotic from another class.
- Hypoglycemiahas been reported more frequently in diabetic patients, predominantly in elderly patients. If this occurs, contact your doctor immediately.
- Diarrheamay develop while taking antibiotics, including Ciprofloxacin, or even several weeks after stopping them. If diarrhea becomes severe or persistent, or if you notice blood or mucus in your stool, stop taking Ciprofloxacin immediately, as it may be life-threatening. Do not take medications that stop or slow down bowel movements, and consult your doctor.
- Consult an ophthalmologist immediately if you experience any vision changesor have any eye problems (see section 4: Possible side effects)
- Your skin becomes more sensitive to sunlight or ultraviolet (UV) lightwhen taking Ciprofloxacin. Avoid exposure to intense sunlight or artificial UV light, such as tanning beds.
- While taking Ciprofloxacin, inform your doctor or laboratory staff if you need to undergo a blood or urine test.
- If you have kidney problems, inform your doctor, as your dose may need to be adjusted.
- Ciprofloxacin may cause liver damage. If you notice symptoms such as loss of appetite, yellowing of the skin (jaundice), dark urine, itching, or stomach pain, stop taking Ciprofloxacin immediately and consult your doctor.
- Ciprofloxacin may cause a decrease in white blood cell count and may decrease your resistance to infections. If you experience an infection with symptoms such as fever and severe deterioration of your general condition, or fever with symptoms of local infection such as sore throat/pharynx/mouth, or urinary problems, consult your doctor immediately. They will perform a blood test to examine the possible decrease in white blood cells (agranulocytosis). It is essential to inform your doctor about your medication.
Quinolone antibiotics may cause an increase in your blood sugar levels above normal levels (hyperglycemia) or a decrease in your blood sugar levels below normal levels, which in severe cases can lead to 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 monitored.
Taking Ciprofloxacin tablets with other medications
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medication.
Do not take Ciprofloxacin at the same time as tizanidine, as this may cause side effects such as low blood pressure and drowsiness (see section 2: "Do not take Ciprofloxacin tablets").
It is known that the following medications interact with Ciprofloxacin in your body. If you take Ciprofloxacin at the same time as these medications, it may affect the therapeutic effect of these medications. It may also increase the likelihood of experiencing side effects.
Inform your doctor if you are taking:
- vitamin K antagonists (e.g., warfarin, acenocoumarol, phenprocoumon, or fluindione) or other oral anticoagulants (to thin the blood)
- probenecid (for gout)
- methotrexate (for certain types of cancer, psoriasis, rheumatoid arthritis)
- theophylline (for respiratory problems)
- tizanidine (for muscle spasticity in multiple sclerosis)
- olanzapine (an antipsychotic)
- clozapine (an antipsychotic)
- ropinirole (for Parkinson's disease)
- phenytoin (for epilepsy)
- metoclopramide (for nausea and vomiting)
- cyclosporine (for skin diseases, rheumatoid arthritis, and organ transplants)
- other medications that may affect your heart rhythm: antiarrhythmic medications (e.g., quinidine, hydroquinidine, disopyramide, amiodarone, sotalol, dofetilide, ibutilide), tricyclic antidepressants, some antimicrobials (belonging to the macrolide group), some antipsychotics.
Ciprofloxacin may increaseblood levels of the following medications:
- pentoxifylline (for circulatory disorders)
- caffeine
- agomelatine
- zolpidem• duloxetine (for depression, diabetic neuropathy, or incontinence)
- lidocaine (for heart conditions or anesthetic use)
- sildenafil (e.g., for erectile dysfunction)
Some medications decreasethe effect of Ciprofloxacin. Inform your doctor if you are taking or plan to take:
- antacids

Medical Advice/Education
Antibiotics are used to treat bacterial infections. They do not work for viral infections.
If your doctor has prescribed antibiotics, you need them precisely for your current illness.
Despite antibiotics, some bacteria may survive or grow. This phenomenon is known as resistance: some antibiotic treatments become ineffective.
Misuse of antibiotics increases resistance. You can even help bacteria become more resistant and thus delay your recovery or reduce the effectiveness of antibiotics if you do not respect:
- the dose
- the antibiotic plan
- the treatment duration
Consequently, to maintain the effectiveness of this medication:
- Use antibiotics only when prescribed.
- Follow the prescription strictly.
- Never reuse an antibiotic without a medical prescription, even if you want to treat a similar illness.
- Never give your antibiotic to another person; it may not be suitable for their illness.
- After completing a treatment, return all unused medications to the pharmacy to ensure they are disposed of correctly.
