More information about Nitrofurantoin
Nitrofurantoin is an antibiotic prescribed to treat urinary tract infections (UTIs), specifically cystitis. It contains the active ingredient of the same name.
Nitrofurantoin is also available as a branded version, sold under different names, such as MacroBID. However, if you buy Nitrofurantoin online from HealthExpress, it has identical properties and effects as MacroBID - coming in the form of 100mg modified-release (MR) capsules or tablets.
You should only take this medication if you have been prescribed it by a doctor (this includes our online prescription). Taking antibiotics unnecessarily will cause more harm than good lead to increased antibiotic resistance.
Please note, this treatment is not available online to men. This is because UTIs are more difficult to diagnose in men and can indicate more serious conditions. If you are male, you should visit your GP or local GUM clinic.
If you are pregnant or trying to conceive, you should ask your doctor about more suitable treatment.
When you take Nitrofurantoin, the active agent is absorbed by the body and eventually concentrates in your urine - this is why it is especially effective at treating UTIs.
As an antibiotic, Nitrofurantoin works by damaging the DNA of the bacterial cells so they are unable to repair or reproduce. It prevents them from creating a necessary protein. Consequently, your immune system can better fight the infection.
Please note, you must complete the prescribed course, even if symptoms clear early. Due to the way antibiotics work, the infection can return if prescribing instructions are not followed.
If you are uncertain about the length of your course, please consult your doctor or patient information leaflet (PIL).
For full instructions, please consult the patient information leaflet (PIL).
To ensure your infection is cleared completely, you should finish your course of treatment, even if you do start to feel better before the full time of treatment.
The antibiotic has different treatment lengths for men and women, as follows:
You should take a 100mg (MR) capsule twice a day, for three days.
Alternatively, if you are prescribed the 50mg dosage, you should take tablets four times a day for three days.
If symptoms persist beyond three days, you can continue to take the medication for up to seven days, or until the symptoms resolve. If symptoms persist beyond seven days, please seek immediate medical advice.
Please note, if you are male, you cannot be prescribed this medication online. You should contact your regular doctor for an in-person diagnosis.
Most UTIs affect the bladder and the urethra, which is the tube that drains urine from the bladder. UTIs are a very common infection for women, but rare for men.
When a man develops a UTI, it is usually considered complicated and more likely to spread to the kidneys.
If diagnosed and prescribed in-person, men should take a 100 mg (modified release) capsule twice a day for seven days to clear the infection. Alternatively, take a 50mg tablet four times a day for seven days.
If symptoms persist beyond seven days of treatment, please seek immediate medical advice.
For a full list of side effects, please read the patient information leaflet. You will find this included with your order.
You should take this medication with food to minimise feelings of nausea.
Nitrofurantoin might cause urine to turn dark yellow or brown in colour, however, this is normal and is only temporary.
Other common side effects include:
If you experience any breathlessness or difficult breathing after starting this treatment, please seek immediate medical attention.
You should report any unlisted side effects to your doctor. You should also inform your doctor if any reactions are unpleasant or long-lasting.
There are some precautionary measures you need to take into consideration before using Nitrofurantoin for the first time.
Before using this medication you should consult your doctor about any allergies or medical conditions as well as your medical history.
If any of the following apply to you, you should seek other treatment:
Please note, Nitrofurantoin can cause bacterial vaccines to not work as effectively. Do not schedule vaccinations during your course of treatment.
You should avoid alcohol when using this medication. Instead, drink plenty of water to help flush the bacteria out.
This medication cannot be prescribed online to women who are pregnant. You should contact your doctor to explore different options.
