Utilizado para

Tratamiento de las infecciones

También llamado

Ciproxin®

Disponible como

Ciprofloxacin is given to treat a bacterial infection. It is useful for treating infections such as chest infections, urine infections, prostatitis, infections of the digestive system, bone and joint infections, and some sexually transmitted infections. It works by killing the bacteria which are the cause of the infection.

Some eye infections are also treated with ciprofloxacin. There is a separate medicine leaflet available called Ciprofloxacin eye preparations which provides further information about this.

Before taking ciprofloxacin

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking ciprofloxacin it is important that your doctor knows:

  • Si está embarazada, esperando un bebé o en período de lactancia.

  • If you are under 18 years of age. This is because ciprofloxacin is only prescribed for children under the supervision of a doctor who is a specialist.

  • If you have ever experienced a problem with your tendons, called tendonitis.

  • Si tiene algún problema con el funcionamiento de sus riñones.

  • If you have epilepsy or any other condition that causes fits.

  • If you have high blood sugar levels (diabetes).

  • If you have a heart condition, or if you have been told you have an unusual heartbeat.

  • If you have a condition causing tired and weak muscles, called myasthenia gravis.

  • If you know you have glucose 6-phosphate dehydrogenase (G6PD) deficiency. This is a genetic disorder which causes problems after eating foods such as fava beans.

  • Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como medicamentos a base de plantas y complementarios.

  • If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your doctor if you have had a problem after taking another quinolone antibiotic (these are called norfloxacin, ofloxacin, levofloxacin, moxifloxacin, and nalidixic acid).

How to take ciprofloxacin

  • Before you start taking ciprofloxacin, read the manufacturer's printed information leaflet from inside the pack. The manufacturer's leaflet will give you more information about the medicine and a full list of the side-effects which you may experience from taking it.

  • Take ciprofloxacin exactly as your doctor tells you to. It is usually taken twice daily for a week or so, although some infections can be treated with a single tablet. Read the label carefully to make sure you know what dose is right for you.

  • Many people find it helps to swallow the tablets with a drink of water. You should swallow the tablets whole - do not crush or chew them as they have an unpleasant taste. You should not take ciprofloxacin with milk or fortified orange juice as these drinks can interfere with the way it works.

  • You can take ciprofloxacin before or after meals. Try to space out your doses - so ideally, take a dose every 12 hours. Try to drink several glasses of water during the day, as this will help the medicine pass through your body.

  • Do not drink milk or take indigestion remedies (antacids) or medicines containing iron or zinc (such as multivitamin tablets), during the two hours before you take ciprofloxacin, or during the two hours after you have taken a dose. This is because these things interfere with the way ciprofloxacin is absorbed by your body, and stop it from working fully. Milk used to prepare meals will not affect the absorption of ciprofloxacin.

  • If you forget to take a dose, take it as soon as you remember. If, when you remember, your next dose is due then take the dose which is due but leave out the forgotten one. Do not 'double up' to make up for a missed dose.

  • Even if you feel your infection has cleared up, keep taking the antibiotic until the course is finished (unless you are told to stop by your doctor). This is to prevent the infection from coming back. A course of treatment usually lasts for about a week or so, although it can range from 3-28 days. If you still feel unwell after finishing the course of treatment, go back to see your doctor.

  • Remember to keep any routine appointments with your doctor. This is so your progress can be monitored.

  • Ciprofloxacin may cause your skin to become more sensitive to sunlight than normal. Protect your skin by using a sunscreen, particularly if you are exposed to strong sunlight for a prolonged period of time. Do not use sunbeds.

  • If you buy any medicines, check with a pharmacist that they are safe to take with this antibiotic. In particular, do not take painkillers called non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, while you are taking ciprofloxacin.

  • Some people develop thrush (redness and itching in the mouth or vagina) after taking a course of antibiotics. If you think you have thrush, speak with your doctor or pharmacist for advice.

  • This antibiotic may stop the oral typhoid vaccine from working. If you are due to have any vaccinations, make sure the person treating you knows that you are taking this medicine.

  • Ciprofloxacin may make you feel light-headed and impair your ability to concentrate. Make sure your reactions are normal before you drive and before you use tools or machines.

  • If you have diabetes, you may need to check your blood glucose levels more regularly, as ciprofloxacin can affect the levels of sugar in your blood.
