Nitrofurantoin, sometimes sold under the name "Macrobid", is an antibiotic for cystitis, and works by killing the bacteria which cause bladder infections. The most recent guidelines from the National Institute of Health and Care Excellence show that Nitrofurantoin is now the best antibiotic treatment for cystitis in the UK.
You can order Nitrofurantoin for a current infection, or order a future supply of Nitrofurantoin so that you can start treatment as soon as you get an infection.
If you think you have the symptoms of cystitis or a UTI, but you're not quite sure, you can order our TestCard bundle. This is a simple at-home test you can take to find out if you have a UTI (Urinary tract infection) that also includes treatment.
To place an order, fill in a brief questionnaire. One of our doctors will review your order and prescribe a suitable treatment.

About Nitrofurantoin
How does Nitrofurantoin work?
Nitrofurantoin is an antibiotic. It works by killing the bacteria which commonly cause cystitis. Unlike many other antibiotics, a sufficient amount of nitrofurantoin is passed with your urine, which is why it is highly effective in treating infections of the bladder.
Nitrofurantoin Dosage
You need to take one nitrofurantoin 100mg dose in the morning and one in the evening. You should aim to take the tablets at the same time every day. The course will last for three days. The tablets need to be swallowed whole with a drink of water.You may feel better before you have completed the course of antibiotics. However, it is important that you finish your course as advised, even if you feel better. If you stop taking your antibiotic early, the bacteria which cause cystitis can become resistant to the medication. If this happens, your infection will return and it can be very difficult to treat. Taking your tablets twice daily for three days will prevent this from happening.
What is the difference between MacroBid and nitrofurantoin?
MacroBid is a brand name for nitrofurantoin, which is the active substance the tablets contain. Nitrofurantoin is also available under other brand names.
Is nitrofurantoin available over the counter?
Nitrofurantoin is an antibiotic and therefore not available over the counter. You need a prescription to buy and take it, as it is important that a doctor checks whether you suffer from a bacterial infection that nitrofurantoin is effective for. Your prescribing doctor will also check whether the antibiotic is suitable for you based on your medical history.
To obtain your prescription and medication online, use our convenient online doctor service. One of our online doctors will review your order and assess whether nitrofurantoin is the best cystitis treatment for you.

I have never been given capsules for any UTI and have always been given the same powder tablets. I am a life long vegetarian and was super disappointed to recieve capsules containing gelatin, that I couldn't take. £28 for said capsules is a lot when you can't take them.

Good product, but more expensive than a prescription.
-
Very pleased to get this short course of antibiotics on-line. Worked well. Costs, but balance it out against the hassle of phoning Drs, waiting for call back from Dr (if any phone appointments available on the day) Saved hassle and worry and stress waiting for phone call. Also delivered to your door when you are too ill to pick up prescription and have no one else to do this for you. Very pleased with the efficiency of this service. Will use again, and recommend this service to other people.
-
The product did as it says on the tin
-
Worked effectively. After reading some of the previous reviews, I was concerned about side effects but fortunately did not have any.
-
Product worked well
-
Great help got rid of my pain

This is a great service saved me hours waiting at the doctors and hours waiting to get through to a doctor small questionnaire that took 5 minutes and medications was very reasonably priced I will definitely use again
-
So much easier than trying to see my doctor..
