This prescription is designed for EU-wide recognition, though pharmacists retain the right to refuse.

How it works — get your consultation in 4 steps

  1. Fill out our secure online medical questionnaire and pay the 35 € consultation fee.
  2. A licensed EU doctor privately reviews your case. If the doctor determines treatment with Nitrofurantoin is not appropriate for you, your fee is refunded automatically — you pay nothing.
  3. If approved, you receive a valid electronic prescription (a downloadable PDF file) in your Hi-Doctor account and by email within 24 hours.
  4. Print the PDF or show it on your phone — present it at any pharmacy in the EU. Pharmacists retain the right to refuse, but may dispense a locally-marketed equivalent.

Who qualifies for treatment

Hi-Doctor's EU-licensed doctors consider Nitrofurantoin only for uncomplicated urinary tract infections (acute cystitis) in eligible adult patients. When you complete the online questionnaire, the doctor will carefully assess several factors:

  • Your symptoms: Typical symptoms of acute cystitis, such as painful urination, frequent urges, and lower abdominal discomfort.
  • Medical history: The doctor reviews your past health conditions, allergies, and current medications to ensure Nitrofurantoin is safe for you.
  • Exclusion criteria: You will not qualify if you have symptoms of a complicated UTI (e.g., fever, back pain, nausea), a history of kidney issues, or are pregnant or breastfeeding. Nitrofurantoin is not prescribed for male UTIs, STIs, or asymptomatic bacteriuria through this service.

What Nitrofurantoin actually does (and doesn't do)

Nitrofurantoin is an antibiotic specifically designed to treat bacterial infections in the urinary tract. It works by preventing bacteria from growing and multiplying in your urine. Most patients experience relief from symptoms within 24 to 48 hours of starting treatment. It's crucial to complete the full course of medication as prescribed, even if you feel better, to ensure the infection is fully cleared and to prevent resistance.

However, Nitrofurantoin is not a general antibiotic for all infections. It is ineffective against viral infections and will not treat sexually transmitted infections (STIs) or kidney infections (pyelonephritis).

Side effects and when to stop

Like all medications, Nitrofurantoin can cause side effects. Common side effects include nausea, vomiting, loss of appetite, and headache. These are usually mild and temporary. More serious, but rare, side effects can include allergic reactions, liver problems, or lung reactions. You should stop taking Nitrofurantoin and seek immediate medical attention if you experience:

  • Severe allergic reaction (rash, itching, swelling, severe dizziness, trouble breathing).
  • Persistent or worsening fever, chills, or body aches.
  • Yellowing of the skin or eyes (jaundice).
  • Severe abdominal pain or persistent vomiting.
