From the Research

Several antibiotics commonly used for urinary tract infections (UTIs) can be crushed for patients who have difficulty swallowing pills, including nitrofurantoin monohydrate macrocrystals, trimethoprim-sulfamethoxazole, amoxicillin, and amoxicillin-clavulanate, as well as cephalexin capsules which can be opened and the contents mixed with food 1.

Key Points to Consider

  • Nitrofurantoin monohydrate macrocrystals (Macrobid) can be opened and the contents mixed with food, though the regular release form (Macrodantin) should not be crushed as it may cause stomach irritation.
  • Trimethoprim-sulfamethoxazole (Bactrim, Septra) tablets can be crushed and mixed with liquid.
  • Amoxicillin and amoxicillin-clavulanate (Augmentin) are available as chewable tablets or can be crushed and mixed with food.
  • Cephalexin (Keflex) capsules can be opened and the contents mixed with food.
  • Certain antibiotics like ciprofloxacin (Cipro) and levofloxacin (Levaquin) should not be crushed as this may affect their absorption and efficacy.

Important Considerations

  • Always check with a pharmacist before crushing any medication, as crushing may alter the drug's release pattern and effectiveness.
  • For patients who cannot swallow pills, asking for liquid formulations is often a better alternative than crushing tablets, as many antibiotics are available in suspension form specifically for this purpose.
  • The most recent study 1 suggests that fosfomycin is the most effective antibiotic in treating uncomplicated UTIs with respect to clinical cure, microbiological cure, and adverse events profile, and it can be considered as a viable option for patients who have difficulty swallowing pills.
