Nitrofurantoin (the active ingredient) is an antibiotic, used to prevent and treat infections of the bladder, kidney and other parts of the urinary tract.
High levels of nitrofurantoin get filtered out of the blood and into the urine by your kidneys. This puts the medicine right among the bacteria that are causing the infection, and then kills them.
Infections of the bladder, kidneys and urinary tract can be painful and extremely uncomfortable. Treating these infections with a simple course of antibiotics will get you feeling healthy and happy again.
By opting for a drug that’s specifically tailored to target the bacteria at its source, Nitrofurantoin provides a much more efficient and effective treatment than other antibiotics.
Nitrofurantoin is a prescription-only medication. Always follow the advice of your doctor and read the patient information leaflet provided in the medication packet. Take the tablets orally by swallowing whole at meal times with food or milk. This will help to avoid stomach upset and also to help the absorption.
The dosage will depend on your age, as well as the type of treatment that you need, which can be advised by your doctor. However, it is important that you finish the prescribed course of treatment, even if you start to feel better or your symptoms clear before its end.
Nitrofurantoin tablets come in various sizes (most popular being 50mg and 100mg) which all contain the active antibiotic.
The normal dose for adults depends on the type of infection you have and users should consult their doctor for guidance. Normal doses would be either one 50mg or one 100mg four times a day for seven days to treat infections. To prevent further infections, normal dose would be one 50mg or 100mg tablet at bedtime. For prevention of infections during surgery, normal doses would be one 50mg tablet four times a day on the day of the operation and three days after.
This medication is also suitable for children and again, your doctor will advise of the dosage, based largely on age.
If you take more Nitrofurantoin tablets than you should, you should contact your doctor immediately. If you forget to take a dose then do not worry; if you remember on the same day then take that day’s dose as usual. If you miss a whole day, simply resume taking it normally and don’t double up to make up for the day before.
