Nitrofurantoina per le infezioni urinarie

About nitrofurantoin

Nitrofurantoin is a type of antibiotico used to treat urinary tract infections (UTIs) in adults and children over 3 months.

Most UTIs are caused by germs (bacteria) that come from your own bowel. They are usually easily treated with a short course of an antibacterial medicine such as nitrofurantoin.

Occasionally, longer-term treatment is needed to prevent infections from coming back. Nitrofurantoin works by killing the bacteria causing the infection.

Common side effects of nitrofurantoin are:

• Sensazione di nausea.

• Vomito.

• Perdita di appetito.

• Sensazione di vertigini o sonnolenza.

• Eruzione cutanea pruriginosa.

You will find a full list in the manufacturer's information leaflet supplied with your medicine.

Gli effetti indesiderati spesso migliorano man mano che il tuo corpo si adatta al nuovo medicinale, ma parla con il tuo medico o farmacista se uno dei seguenti persiste o diventa problematico.

Se si verificano altri sintomi che ritieni possano essere dovuti al medicinale, parla con il tuo medico o farmacista per ulteriori consigli.

Some medicines aren’t suitable for certain health conditions or may require extra care. Before taking nitrofurantoin, it is important to let your doctor know:

• If you are pregnant or breastfeeding. Although nitrofurantoin can be taken during pregnancy, it is still important that you tell your doctor about being pregnant.

• Se hai problemi con il funzionamento del tuo fegato, o se hai problemi con il funzionamento dei tuoi reni.

• Se hai il diabete (diabete mellito).

• If you have been told you have anaemia, or if you have low levels of vitamin B or folic acid.

• Se hai problemi respiratori.

• If you have a problem where your nerves cause pain or numbness, called peripheral neuropathy.

• If you have been told you have one of the following rare inherited conditions: porphyria or glucose-6-phosphate dehydrogenase (G6PD) deficiency.

• Se stai assumendo altri medicinali. Questo include qualsiasi medicinale disponibile per l'acquisto senza prescrizione, così come i medicinali a base di erbe e complementari.

• Se hai mai avuto una reazione allergica a un medicinale.

• Read the information leaflet in the pack before starting. It explains nitrofurantoin and its possible side effects.

• Take nitrofurantoin exactly as your doctor instructs. Your dose depends on whether it’s for treating or preventing an infection. Follow the label instructions.

• Take each dose with food or a snack. Space doses evenly: four times a day = every 6 hours, twice a day = every 12 hours, once a day = every 24 hours.

• Finish the full course, even if you feel well, to prevent the infection from returning. Most courses last 3-7 days; for frequent urine infections, treatment may last up to six months.

• If you forget a dose, take it as soon as you remember. Do not take two doses at once to make up for a missed one.

• Most people feel better within a few days. If your symptoms don’t improve, see your doctor as you may need a different antibiotic.

• Nitrofurantoin can turn your urine yellow or brown. This is harmless.

• Check with a pharmacist before taking any other medicines. Some antacids can stop nitrofurantoin from working properly.

• If you take the contraceptive pill, its effectiveness may be reduced if you have vomiting or diarrhoea lasting more than 24 hours. Ask your doctor or pharmacist about extra precautions.

• Tell your doctor or dentist that you are taking nitrofurantoin before any treatment, as it can affect some tests.

• Nitrofurantoin can stop the oral vaccino orale contro il tifo from working. Inform your healthcare provider if you are due for any vaccinations.

• Tenere tutti i medicinali fuori dalla portata e dalla vista dei bambini.

• Conservare in un luogo fresco e asciutto, lontano da fonti di calore e luce diretta.

• The liquid medicine lasts for 30 days after first opening.
