Nitrofurantoin is an antibiotic frequently used to cure urinary tract infections, which are a common problem many women experience at some point in their lives. A course of nitrofurantoin usually involves taking one capsule twice a day for three days - you should notice a significant improvement to your symptoms within this time frame. If your symptoms persist or worsen, you require additional tests to establish whether you do suffer from a water infection and why nitrofurantoin has failed to help.
Macrobid is a branded medication and contains nitrofurantoin. Nitrofurantoin tablets are also sold under the brand names Macrodantin and Furadantin and there are numerous generic versions of the antibiotic. Since all these tablets contain the same active ingredient, they work in the same way and are similarly effective.
Most cases of cystitis improve within days of taking nitrofurantoin or macrobid. In order for nitrofurantoin to be effective, you need to take the course as prescribed. Stopping treatment prematurely can lead to bacteria developing a resistance to nitrofurantoin, making it difficult to cure the infection. If your symptoms have not improved after a few days, you need to seek medical help to conduct further tests and establish the cause of your symptoms.
Most women who suffer from UTI’s can benefit from taking the antibiotic nitrofurantoin but there are some exceptions. If you are allergic to nitrofurantoin, you should ask your doctor for an alternative treatment. If you are suffering from kidney disease or are in the final weeks of pregnancy, you must consult your doctor prior to taking nitrofurantoin, as it may have harmful side effects for you.
Certain illnesses can mean you should abstain from using nitrofurantoin and similar antibiotics, this affects patients with porphyria and G6PD. Other conditions can require extra care when taking certain antibiotics, so if you are diabetic, are suffering from weakness or anemia you must also speak to a doctor to confirm the best treatment option for you. The same goes for patients with illnesses affecting the lungs, liver or nervous system.
Like many other antibiotics, nitrofurantoin can lower the effectiveness of the contraceptive pill. You need to take extra precautions while taking nitrofurantoin, ideally you should use a condom during the time of your treatment and for a week after taking the last tablet. Alternatively, you may consider using a diaphragm and spermicides.
There is no known interaction between nitrofurantoin and alcohol. You should, however, avoid alcohol while you are suffering from cystitis.
When treating a water infection with nitrofurantoin, you will take two tablets per day, normally one in the morning and one in the evening. Every tablet contains 100mg of the active ingredient nitrofurantoin. You should swallow each tablet whole with a drink of water and a meal or a glass of milk. The course will last three days, during which your symptoms should gradually improve.
If you forget to take a dose of nitrofurantoin, you should take the tablet as soon as you remember. In case you have forgotten until it is time for the next dose, just take it as you normally would - do not double the dose.
It is important that you take the correct dose. If you accidentally exceed the daily dosage, you should seek help immediately. Nitrofurantoin is only to be taken by the person it was prescribed to and needs to be stored out of the reach of children.
Whether you are taking Macrobid, Macrodantin, Furadantin or generic nitrofurantoin tablets to cure your urine infection, you will usually take 1 tablet containing 100mg nitrofurantoin twice a day. Other ingredients include talc, lactose, sugar as well as carbopol and povidone. For a full list of ingredients, please read the patient leaflet of your nitrofurantoin tablets.
Most side effects associated with nitrofurantoin are mild and stop as soon as you stop taking the tablets.
The following side effects can occur:
Some patients experience bruising, anemia, susceptibility to colds and other infections while taking nitrofurantoin.
If you experience any of these serious side effects, please seek medical help as soon as possible.
It is not uncommon for the colour of your urine to change while you are taking nitrofurantoin. This is normal and does not require medical attention.
For a complete list of all possible side effects please read the patient leaflet of your specific medication.
Nitrofurantoin interacts with the following types of medication:
If you are unsure as to whether you are taking any of these, please consult your doctor before starting your course of nitrofurantoin.
