However, if you're taking the pill and get vomiting or diarrhoea as a result of taking nitrofurantoin, you should follow the instructions for vomiting and diarrhoea described in the leaflet provided with your pills.Nitrofurantoin is best taken with food or milk. This is the latest guidance from the Faculty of Sexual & Reproductive Healthcare. This is because to date there is no evidence to prove that antibiotics (other than rifampicin or rifabutin) affect these contraceptives. The old advice has changed and you no longer need to use an extra method of contraception with the pill, patch or vaginal ring while you take a course of antibiotics. Nitrofurantoin does not affect the contraceptive pill. The oral typhoid vaccine (Vivotif) should not be taken until at least three days after you have finished a course of nitrofurantoin, because the antibiotic could make this vaccine less effective. These medicines may also increase the risk of nitrofurantoin side effects. Nitrofurantion may be less effective at treating urinary tract infections if it's taken with probenecid or sulfinpyrazone, because these medicines stop as much nitrofurantion getting into the urine. If you need to take an antacid you should take it at least two hours before or two hours after taking a nitrofurantoin dose. Antacids that contain magnesium salts such as magnesium trisilicate may reduce the absorption of nitrofurantion from the gut, which could make it less effective at treating your infection. You shouldn't take an antacid medicine (remedies for indigestion and heartburn) at the same time of day as nitrofurantoin.

Drinking lots of water will help dilute your urine and make it less painful to go to the toilet. These can make the antibiotic less effective at treating the urine infection. It's fine to take over-the-counter painkillers like paracetamol or ibuprofen while you're taking nitrofurantoin.ĭon't take cystitis remedies (like potassium citrate or sodium citrate) to relieve the symptoms of your UTI while you're taking nitrofurantoin.

Similarly, check with your doctor or pharmacist before taking any new medicines while taking nitrofurantoin, to make sure that the combination is safe. It's important to tell your doctor or pharmacist if you're already taking any medicines, including those bought without a prescription and herbal medicines, before you start a course of nitrofurantoin.
