From the Research

Macrobid (nitrofurantoin monohydrate/macrocrystals) 100 mg capsules should not be crushed. These capsules contain a special dual-release formulation with both immediate and extended-release components designed to deliver the medication properly throughout the urinary tract. Crushing would disrupt this carefully designed delivery system and could potentially alter the medication's effectiveness or increase side effects.

Reasons to Avoid Crushing

  • The dual-release system of Macrobid is important because it helps maintain effective antibiotic levels in the urinary tract while minimizing gastrointestinal side effects that can occur with this medication.
  • There is no direct evidence in the provided studies 1, 2, 3, 4, 5 that supports crushing Macrobid capsules as a safe or effective practice.
  • The most recent and highest quality study 5 discusses the efficacy and toxicity of nitrofurantoin in the treatment of lower urinary tract infections but does not address the issue of crushing the capsules.

Alternative Options

If you have difficulty swallowing the capsule, you should speak with your healthcare provider about alternative options. Some alternatives might include:

  • Nitrofurantoin oral suspension (if available)
  • A different antibiotic altogether that would be appropriate for your specific infection It's crucial to follow the prescribed formulation and administration instructions to ensure the medication's effectiveness and minimize potential side effects.
