It is quite common to experience nausea and vomiting while taking antibiotics like Martifur (nitrofurantoin) and Monocef (ceftriaxone). However, constant vomiting is concerning as it can lead to dehydration and prevent her from absorbing her medicine. To help her, offer small, frequent sips of water or electrolyte solutions, and try giving her oral medication with food. Please contact her doctor promptly; they can prescribe an effective anti-nausea medication or adjust her treatment.

The dosage of Martifur varies depending on the type and severity of the infection and the patient?s overall health. It should be taken strictly as advised by the doctor, and the dose should not be changed or stopped without medical guidance.
