Indications
Macrodantin (active ingredient: nitrofurantoin) is a prescription medication indicated:
- Urinary Tract Infections: Macrodantin is used for the treatment and prevention of urinary tract infections (UTIs) caused by susceptible bacteria, including acute and chronic cystitis.
Macrodantin belongs to a class of drugs known as nitrofuran antibiotics, which work by interfering with bacterial cell wall synthesis and other essential bacterial processes, ultimately leading to bacterial cell death.
Uses and Dosage
Macrodantin comes in the form of a capsule that should be taken by mouth with food or milk, as directed by a healthcare provider. Swallow the capsule whole, without crushing or chewing them, unless otherwise instructed by your healthcare provider. For the prevention of urinary tract infections, Macrodantin is usually taken once daily at bedtime. In the case of treatment for an active infection, Macrodantin may be taken four times daily, with doses spaced evenly throughout the day.
Follow your doctor's instructions carefully, and complete the full course of treatment, even if you start feeling better before the medication is finished. The dosage and frequency of administration may vary depending on the individual's medical condition, age, and response to treatment.

Caution
- Avoid using magnesium trisilicate-containing antacids while taking this medication. Magnesium trisilicate-containing antacids bind with nitrofurantoin, preventing its full absorption.
- To prevent dehydration caused by mild diarrhea after taking nitrofurantoin (Macrobid), drink plenty of fluids and consider taking probiotic supplements.
- To avoid the antibiotic from killing the beneficial bacteria in the probiotic, take the probiotic supplement at least 2 hours apart from your nitrofurantoin (Macrobid) dose.
- Discuss with your healthcare provider about the risks and benefits of taking nitrofurantoin (Macrobid) if you're pregnant. It might depend on how far along you are in your pregnancy.
- To ensure proper absorption of nitrofurantoin (Macrobid) and reduce stomach-related side effects, it is recommended to take it with food.
- To ensure that your infection is completely treated, take all the nitrofurantoin (Macrobid) that your healthcare provider has prescribed, even if you start to feel better. Stopping the antibiotic too soon can result in the infection returning and may require more aggressive treatment.
- Before taking nitrofurantoin, inform your doctor or pharmacist of any allergies you have. Nitrofurantoin may contain inactive ingredients that can trigger allergic reactions or other issues. Contact your pharmacist for further information.
