|Treatments > Medications Used In MS|
Finish the full course of treatment prescribed by your doctor, and avoid missing doses. Even if your symptoms disappear after a few days, stopping this medication prematurely may result in a return of the symptoms.
If you miss a dose of this medication, take it as soon as possible. If, however, it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double dose.
The use of nitrofurantoin may cause your urine to become rust-yellow or brownish. This change does not require medical treatment and does not need to be reported to your physician.
If you will be taking this medication over an extended period of time, your doctor will need to check your progress at regular visits. If your symptoms do not improve within a few days, or become worse, consult your physician.
Individuals with diabetes may find that this medication alters the results of some urine sugar tests. Consult with your physician before changing your diet or the dosage of your diabetes medicine.
Certain medical conditions can affect the use of nitrofurantoin. Be sure to alert your physician about any medical conditions you have, especially glucose-6-phosphate dehydrogenase (G6PD) deficiency, kidney disease, or lung disease.
Because nitrofurantoin can cause problems in infants, it should not be used by a woman who is within a week or two of her delivery date, or during labor and delivery.
Nitrofurantoin passes into the breast milk in small amounts and may cause problems in nursing babies (especially those with glucose-6-phosphate dehydrogenase (G6PD) deficiency).
Possible Side Effects
Rare side effects that should be reported to your doctor immediately: chest pain; chills; cough; fever; trouble breathing; dizziness; headache; numbness, tingling, or burning of face or mouth*; unusual weakness or tiredness*; itching; joint pain; skin rash; yellow eyes or skin.
*Since it may be difficult to distinguish between certain common symptoms of MS and some side effects of nitrofurantoin , be sure to consult your health care professional if an abrupt change of this type occurs.
