Nitrofurantoin is an antibiotic typically used to treat urinary tract infections (UTIs), such as cystitis. This treatment should help to relieve any symptoms within a few days.

As an antibiotic, Nitrofurantoin works by preventing the growth of bacteria in the urinary tract. This clears up the infection and relieves irritating symptoms.

Pharmacy Online prescribes Nitrofurantoin 50mg in the form of tablets, these are taken orally four times a day. However, more severe UTI infections may require a higher Nitrofurantoin dosage.


  • How can I manage Nitrofurantoin side effects?

    Nitrofurantoin can cause stomach disturbance side effects such as diarrhoea and nausea. Diarrhoea side effects can be reduced by using over the counter treatments such as Loperamide. Nausea can be prevented by taking Nitrofurantoin with or just after food. 

    To manage vomiting side effects, Pharmacy Online prescribes suitable medications such as Cyclizine, Promethazine, and Prochlorperazine.

  • Can I drink alcohol with Nitrofurantoin?

    Taking nitrofurantoin may cause thrush, as the antibiotic destroys the bacteria present in the urinary tract which protects you from developing thrush. This means there is a risk of developing thrush when taking Nitrofurantoin.

  • Can I use Nitrofurantoin if I’m pregnant?

    Avoid using Nitrofurantoin during the final 2 to 4 weeks of pregnancy. There are no risks to an unborn baby when using Nitrofurantoin when used before the last 2 to 4 weeks of pregnancy.

  • How long does it take for Nitrofurantoin to start working?

    Nitrofurantoin usually begins to show its effects after 48 hours. It is recommended that you take Nitrofurantoin for the full prescribed course, even if your symptoms begin to clear since this helps prevent the growth of any further bacteria.

  • What type of bacteria does Nitrofurantoin kill?

    Nitrofurantoin will only target bacteria present in the urinary tract, as the antibiotic properties are absorbed through the blood and into the urine, then passing through the urinary tract in order to destroy UTI bacteria.

  • Who should not take Nitrofurantoin?

    You should avoid taking Nitrofurantoin if you have certain health conditions including severe kidney disease, liver problems, urinary problems or jaundice.
