Warnings and precautions

Before taking this medicine

You should not take fluoroquinolone/quinolone antibacterial medicines, including Ciprofloxacin 500mg Tablets, if you have experienced any serious adverse reaction in the past when taking a quinolone or fluoroquinolone. In this situation, you should inform your doctor as soon as possible.

Talk to your doctor before taking Ciprofloxacin 500mg Tablets

  • if you have ever had kidney problems because 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 such as Ciprofloxacin Tablets
  • if you are diabetic because you may experience a risk of hypoglycaemia with ciprofloxacin
  • if you have myasthenia gravis (a type of muscle weakness)
  • if you have heart problems: Caution should be taken when using this kind of medicine, if you were born with or have a family history of prolonged QT interval (seen on ECG, electrical recording of the heart), have salt imbalance in the blood (especially low levels of potassium or magnesium in the blood), have a very slow heart rhythm (called ‘bradycardia’), have a weak heart (heart failure), have a history of heart attack (myocardial infarction), you are female or elderly or you are taking other medicines that result in abnormal ECG changes (see section Other medicines and Ciprofloxacin 500mg Tablets)
  • if you have been diagnosed with an enlargement or “bulge” of a large blood vessel (aortic aneurysm or large vessel peripheral aneurysm)
  • if you have experienced a previous episode of aortic dissection (a tear in the aorta wall)
  • if you have a family history of aortic aneurysm or aortic dissection or other risk factors or predisposing conditions (e.g. connective tissue disorders such as Marfan syndrome, or vascular Ehlers-Danlos syndrome, or vascular disorders such as Takayasu arteritis, giant cell arteritis, Behcet’s disease, high blood pressure, or known atherosclerosis)
  • if you or a member of your family is known to have a deficiency in glucose-6-phosphate dehydrogenase (G6PD) (disease of the red blood cells based on a hereditary enzyme deficiency)because taking ciprofloxacin may lead to a destruction of red blood cells causing anaemia. Signs of anaemia are a feeling of weakness and in more severe cases, breathlessness and pale skin.

If you feel sudden, severe pain in your abdomen, chest or back, go immediately to an emergency room.

For the treatment of some genital tract infections, your doctor can 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 500mg Tablets

Prolonged, disabling and potentially irreversible serious side effects

Fluoroquinolone/quinolone antibacterial medicines. Including Ciprofloxacin 500mg Tablets, have been associated with very rare but serious side effects, some of them being long lasting (continuing months or years), disabling or potentially irreversible. This includes tendon, muscle and joint pain of the upper and lower limbs, difficulty in walking, abnormal sensations such as pins and needles, tingling, tickling, numbness or burning (paraesthesia), sensory disorders including impairment of vision, taste and smell, and hearing, depression, memory impairment, severe fatigue, and severe sleep disorders.

If you experience any of these side effects after taking Ciprofloxacin 500mg Tablets, contact your doctor immediately prior to continuing treatment. You and your doctor will decide on continuing the treatment considering also an antibiotic from another class.

Tell your doctor immediately if any of the following occurs while taking Ciprofloxacin 500mg Tablets.

Your doctor will decide whether treatment with Ciprofloxacin 500mg Tablets needs to be stopped.

  • Severe, sudden allergic reaction (an anaphylactic reaction/shock, angio-oedema). Even after the first dose, there is a small chance that you may experience a severe allergic reaction with the following symptoms: tightness in the chest, feeling dizzy, sick or faint or experiencing dizziness when standing up. If this happens stop taking Ciprofloxacin and contact your doctor immediately.
  • If your eyesight becomes impaired or if your eyes seem to be otherwise affected, consult an eye specialist immediately.
  • Pain and swelling in the joints and tendinitis and inflammation or rupture of tendons may occur rarely. Your risk is increased if you are elderly (above 60 years of age), have received an organ transplant, have kidney problems or if you are being treated with corticosteroids. Inflammation and ruptures of tendons may occur within the first 48 hours of treatment and even up to several months after stopping of Ciprofloxacin 500mg Tablets therapy. At the first sign of pain or inflammation of a tendon (for example in your ankle, wrist, elbow, shoulder or knee), stop taking Ciprofloxacin 500mg Tablets, contact your doctor and rest the painful area. Avoid any unnecessary exercise as this might increase the risk of a tendon rupture.
  • If you suffer from epilepsy or other neurological conditions such as cerebral ischemia or stroke, you may experience side effects associated with the central nervous system. If this happens, stop taking Ciprofloxacin and contact your doctor immediately.
  • You may experience psychiatric reactions the first time you take Ciprofloxacin. If you suffer from depression or psychosis, your symptoms may become worse under treatment with Ciprofloxacin. In rare cases, depression or psychosis can progress to thoughts of suicide, suicide attempts, or completed suicide. If this happens, stop taking Ciprofloxacin and contact your doctor immediately.
  • You may rarely 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 and inform your doctor immediately in order to prevent the development of potentially irreversible condition.
  • Quinolone antibiotics may cause an increase of your blood sugar levels above normal levels (hyperglycaemia), or lowering of your blood sugar levels below normal levels, potentially leading to loss of consciousness (hypoglycaemic coma) in severe cases (see section 4). This is important for people who have diabetes. If you suffer from diabetes, your blood sugar should be carefully monitored.
  • Diarrhoea may develop while you are taking antibiotics including Ciprofloxacin, or even several weeks after you have stopped taking them. If it becomes severe or persistent or you notice that your stool contains blood or mucus, stop taking Ciprofloxacin immediately, as this can be life-threatening. Do not take medicines that stop or slow down bowel movements and contact your doctor.
  • Tell the doctor or laboratory staff that you are taking Ciprofloxacin if you have to provide a blood or urine sample.
  • If you suffer from kidney problems, tell the doctor because your dose may need to be adjusted.
  • Ciprofloxacin may cause liver damage: If you notice any symptoms such as loss of appetite, jaundice (yellowing of the skin), dark urine, itching or tenderness of the stomach, stop taking Ciprofloxacin and contact your doctor immediately.
  • Ciprofloxacin may cause a reduction in the number of white blood cells and your resistance to infection may be decreased. If you experience an infection with symptoms such as fever and serious deterioration of your general condition, or fever with local infection symptoms such as sore throat/pharynx/mouth or urinary problems you should see your doctor immediately. A blood test will be taken to check possible reduction of white blood cells (agranulocytosis). It is important to inform your doctor about your medicine.
  • Your skin becomes more sensitive to sunlight or ultraviolet (UV) light when taking Ciprofloxacin. Avoid exposure to strong sunlight, sunlamps or other sources of UV radiation. If exposure to sunlight is inevitable you should use sun cream to protect yourself. If you experience a fever, rash, itching or small red spots on the skin, you should consult your doctor immediately since the treatment may be discontinued.
  • Crystalluria, (presence of crystals in the urine with discomfort when passing urine) may occur. Consult your doctor as your urine needs to be tested. Furthermore, you should drink a sufficient amount of liquid (about 1.5-2 litres per day).
  • Tuberculosis test (Mycobacterium). Ciprofloxacin may cause a false test result.
  • If your eyesight becomes impaired or if your eyes seem to be otherwise affected, consult an eye specialist immediately.

Other medicines and Ciprofloxacin 500mg Tablets.

If Ciprofloxacin 500mg Tablets and one of the following medicines are given at the same time, special care must be taken:

Tell your doctor if you are taking:

  • Vitamin K antagonists (e.g. warfarin) or other oral-anti-coagulants (to thin the blood)

Some medicines reduce the effect of Ciprofloxacin.

Tell your doctor if you take or wish to take:.

  • antacids
  • omeprazole
  • mineral supplements
  • sucralfate
  • a polymeric phosphate binder (e.g. sevelamer or lanthanum carbonate)
  • medicine or supplements containing calcium, magnesium, aluminium or iron.

If these preparations are essential, take Ciprofloxacin about two hours before or no sooner than four hours after taking them.

Ciprofloxacin 500mg Tablets with food and drink

Large amounts of dairy products particularly milk or yoghurt may slow down ciprofloxacin uptake, therefore ciprofloxacin should be taken 1 to 2 hours before or at least 4 hours after these products.

Surgical procedures

Tell your doctor that you are taking ciprofloxacin because pain relief and sedative medicines administered prior to surgery can also be affected by ciprofloxacin.

If one of the above-mentioned situations is applicable to you, your doctor may decide to prescribe another medicine or to adjust the dose of Ciprofloxacin 500mg Tablets or the other medicine.

It is advisable never to use several medicines at the same time without consulting your doctor first.


If you are pregnant or breast feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

It is preferable to avoid the use of Ciprofloxacin during pregnancy.


Ciprofloxacin is passed into human breast milk. You must not breast-feed your child during treatment with ciprofloxacin, due to the risk of malformation of joint cartilage and other harmful effects in the breast-fed infant.

Driving and using machines

Ciprofloxacin can reduce your attention. If you suffer from dizziness, do not drive or operate machines, which require your full concentration.

3. How to take Ciprofloxacin 500mg Tablets

You should follow your doctor’s instructions and check the pharmacist’s label for how many tablets to take, and when. The usual doses for different types of infections treated with Ciprofloxacin 500mg Tablets are given below as a guide:

Respiratory tract infections 1 tablet twice a day for 7 to 14 days.

Pyelonephritis 1 tablet twice a day for 7 to 14 days.

Prostatitis 1 tablet twice a day for up to 28 days

Severe gastroenteritis 1 tablet twice a day for 3 to 7 days.

Skin and soft tissue infections 1 tablet twice a day for 5 to 10 days.

Bone and joint infections 1 tablet twice a day for 4 to 6 weeks or longer.

Severe systemic infections 1 tablet twice a day.

Acute, uncomplicated gonorrhea a single dose of 1 tablet.

The actual dose may be adjusted to take into account your age, severity of infection and how well your kidneys are working. If you have a severe infection and serious kidney problems your doctor may take regular blood samples to check your recovery and ensure you are receiving the correct dose. Ideally these tablets should be swallowed whole with a glass of water. These tablets can be taken at any time, with or without food. Taking the tablets on an empty stomach will speed up the uptake, whilst dairy products such as milk or yoghurt may slow down the uptake of ciprofloxacin in the stomach.

If you take more Ciprofloxacin 500mg Tablets than you should

If you take more than you should, or in the event of an overdose, seek medical advice immediately and, if possible, take any remaining tablets or this leaflet with you to show the doctor.

If you forget to take Ciprofloxacin 500mg Tablets

If you forget to take your medicine take the missed dose as soon as possible and then continue as normal. However, if it is almost time for your next dose, do not take the missed dose and continue as usual. Do not take a double dose to make up for the forgotten one.

If you stop taking Ciprofloxacin 500mg Tablets

You should continue to take these tablets for as long as directed by your doctor. It is important that you complete the course of treatment, even if you begin to feel better after a few days. If you stop taking this medicine too soon, your symptoms may return.
