Available in strengths of <strong>100 mg<\/strong>.<\/p>\n<p><strong>Important note on category:<\/strong> nitrofurantoin treats bacterial UTIs \u2014 it is not used for sexually transmitted infections. Although UTIs and STIs can both cause dysuria (painful urination), the pathogens, treatments, and follow-up differ significantly.<\/p>\n<h2><strong>Klinisk bruk<\/strong><\/h2>\n<ul>\n<li><strong>Uncomplicated UTI (cystitis) in women:<\/strong> 100 mg twice daily for 5 days (modified-release) \u2014 first-line per IDSA, EAU, NICE.<\/li>\n<li><strong>UTI prophylaxis (long-term):<\/strong> 50\u2013100 mg once daily at bedtime for recurrent UTIs (short or long term).<\/li>\n<li><strong>Asymptomatisk bakteriuri under svangerskap<\/strong> (first and second trimester): 100 mg twice daily for 5\u20137 days. <strong>Avoid at term (\u226536 weeks)<\/strong> \u2014 see below.<\/li>\n<li><strong>Ikke egnet for:<\/strong> kidney infections (pyelonephritis) \u2014 nitrofurantoin does not achieve adequate tissue concentrations outside the urine. <strong>Not for<\/strong> prostate infections, bloodstream infections, or systemic sepsis.<\/li>\n<\/ul>\n<h2><strong>Hvordan ta<\/strong><\/h2>\n<ol>\n<li>Take with food or milk \u2014 improves absorption and reduces stomach upset.<\/li>\n<li>Swallow capsules whole with a full glass of water.

Nitrofurantoin treats UTIs caused by <em>E. coli<\/em>, <em>Enterococcus<\/em>, <em>Staphylococcus saprophyticus<\/em>, og <em>Klebsiella<\/em>. Den gjelder <strong>ikke<\/strong> treat chlamydia, gonorrhea, mycoplasma, or trichomonas. If you have recent new sexual partner(s) or urethral discharge, test for STIs before assuming a UTI.<\/p>\n<h2><strong>Oppbevaring<\/strong><\/h2>\n<p>Store at room temperature (15\u201325 \u00b0C \/ 59\u201377 \u00b0F), away from moisture and light. Keep in original packaging. Keep out of reach of children.<\/p>\n<h2 id=\"faqs\">Vanlige sp\u00f8rsm\u00e5l<\/h2>\n<h3 class=\"wp-block-heading\">Why is Urifon first-line for UTI?<\/h3>\n<p>Nitrofurantoin has a narrow spectrum (mostly UTI pathogens), concentrates in urine, and has stable resistance rates even after 60 years of use. It spares gut flora better than broad-spectrum alternatives like trimethoprim-sulfamethoxazole or fluoroquinolones.<\/p>\n<h3 class=\"wp-block-heading\">How fast does Urifon work?<\/h3>\n<p>Most patients feel improvement within 24\u201348 hours. Full 5-day course is still required \u2014 stopping early leaves residual bacteria that can re-establish infection.<\/p>\n<h3 class=\"wp-block-heading\">Can I use Urifon for a kidney infection?<\/h3>\n<p>No. Nitrofurantoin does not reach adequate tissue levels outside urine, so it cannot treat pyelonephritis or pyelitis. Fever, flank pain, or nausea with UTI symptoms need a different antibiotic.<\/p>\n<h3 class=\"wp-block-heading\">Why does my urine turn dark?<\/h3>\n<p>Nitrofurantoin colours urine dark yellow, brown, or rust \u2014 this is harmless and stops when treatment ends. Does not indicate bleeding or kidney damage.<\/p>\n<h3 class=\"wp-block-heading\">Can I take Urifon while pregnant?<\/h3>\n<p>In the first and second trimesters, yes \u2014 widely used and considered safe. Avoid at term (\u226536 weeks) and during labour due to neonatal hemolytic anaemia risk.<\/p>\n<h3 class=\"wp-block-heading\">Can Urifon be used for STIs?<\/h3>\n<p>No. Nitrofurantoin does not cover chlamydia, gonorrhea, mycoplasma genitalium, or trichomonas. If your symptoms include urethral discharge, genital ulcers, or recent new sexual contact, request STI testing \u2014 treatment is different.<\/p>\n<h3 class=\"wp-block-heading\">Can I take Urifon with birth control pills?<\/h3>\n<p>Yes \u2014 no significant interaction with hormonal contraceptives. Continue your usual pill\/patch\/ring as prescribed.<\/p>\n<h3 class=\"wp-block-heading\">What if UTIs keep coming back?<\/h3>\n<p>Recurrent UTIs (\u22652 in 6 months or \u22653 in 12 months) warrant investigation. Options include post-coital single-dose prophylaxis, nightly low-dose prophylaxis, vaginal oestrogen (post-menopause), and behavioural changes.
