Nitrofurantoin Capsules 100 mg (Nitrotime) are used to treat urinary tract infections (UTIs) caused by specific bacteria. Nitrofurantoin is an antibiotic that works by interfering with bacterial cell metabolism, effectively killing bacteria and alleviating infection. Typically taken twice daily with food to enhance absorption, common side effects include nausea, headache, and a rare risk of lung or liver issues. It is important to complete the full course of the medication to ensure the infection is fully cleared and to prevent resistance. If symptoms persist or you experience severe side effects, consult your healthcare provider promptly. Follow all dosage instructions and avoid using it if you have certain kidney conditions.
