Nitrofurantoin Tablets are an antibacterial medicine mainly used for the treatment and prevention of urinary tract infections (UTIs).

Here are the key details:

• Main Uses:

  • Treatment of acute uncomplicated urinary tract infections, especially bladder infections (cystitis).

  • Prevention of recurrent UTIs in patients prone to frequent infections.

  • Not generally used for kidney infections (pyelonephritis) or systemic infections, as it concentrates mainly in the urine.

• How It Works:

  • Nitrofurantoin damages the bacterial DNA and proteins, preventing the bacteria from multiplying and killing them.

  • It is especially effective against bacteria commonly found in the urinary tract.

• Administration:

  • Taken orally, usually 2 to 4 times daily depending on whether it’s for treatment or prevention.

  • Should be taken with food or milk to improve absorption and reduce stomach irritation.

• Common Side Effects:

  • Nausea, vomiting, loss of appetite.

  • Stomach upset, diarrhea, or mild headache.

  • Dark yellow or brown urine (usually harmless).

• Serious Concerns:

  • Rare but possible lung reactions (shortness of breath, cough).

  • Liver problems in long-term users.

  • May cause nerve-related side effects (numbness, tingling).

  • Hemolytic anemia may occur in patients with G6PD deficiency.

• Precautions:

  • Not suitable for patients with severe kidney disease, as the drug needs to reach high concentrations in urine to work effectively.

  • Long-term use should be closely monitored for liver and lung side effects.

  • Avoid alcohol to reduce stomach irritation.

  • Should be used cautiously in elderly patients.

• Storage: Store in a cool, dry place, away from moisture, heat, and sunlight.

👉 Nitrofurantoin is often a first-choice medicine for bladder infections, especially in women, because it is effective and resistant bacteria are less common compared to some other antibiotics.
