The suspension and its paediatric dosing are not covered here, as this section deals with adults only.
Side Effects
Most people taking nitrofurantoin notice nausea, headache, or gas as the most common side effects. Less commonly, it can cause diarrhea, indigestion, stomach pain, constipation, vomiting, dizziness, or drowsiness.
Cautions & Contraindications
Warnings & Precautions
If you notice signs of a lung reaction, whether sudden, short-term or long-lasting, NFT should be stopped. Don't take antacids that contain magnesium trisilicate while you are on NFT.
Contraindications
Nitrofurantoin should not be used by patients with anuria, oliguria, or significantly reduced kidney function. It is also contraindicated for pregnant women between 38 and 42 weeks of pregnancy, as well as during labor and delivery. Patients known to be hypersensitive to Nitrofurantoin should not take this medicine either.
Pregnancy & Breastfeeding
Pregnancy Category B. Well-controlled studies in pregnant women are lacking, so this medicine should be used in pregnancy only if there is a clear need for it. Nitrofurantoin passes into breast milk in trace amounts. Because nursing infants under one month of age may be more susceptible to serious side effects from it, the mother and her doctor should decide together whether to stop breastfeeding or stop the medicine, weighing how important it is for her treatment.
