2. What you need to know before you take Spiraxin

Do not take Spiraxin:

  • If you are allergic to the active substance, rifamycin derivatives, or any of the other components of this medicine (listed in section 6).
  • If you have intestinal obstruction.
  • If you have severe intestinal ulcerative lesions.
  • If you have complicated diarrhea with fever or blood in the stool.

Warnings and precautions

  • Consult your doctor or pharmacist before starting to take Spiraxin.
  • If you have ever developed a severe skin rash or skin peeling, blisters, and/or sores in the mouth after taking rifaximin.
  • During prolonged treatments at high doses, or in cases of intestinal injury, a slight absorption of the product may occur, and when eliminated, it may cause a reddish coloration of the urine, which is of no significant relevance.
  • Rifaximin should be withdrawn if symptoms of diarrhea persist or worsen after 48 hours.
  • As with the use of most antibiotics, during treatment with rifaximin, cases of diarrhea associated with Clostridioidesdifficile(CDAD) have been reported; therefore, the potential association of rifaximin treatment with CDAD or pseudomembranous colitis cannot be ruled out.

Be particularly careful with rifaximin:

Severe skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, have been reported in association with rifaximin treatment. Most cases were reported in patients with liver disease (such as cirrhosis or hepatitis). Stop using rifaximin and seek immediate medical attention if you notice any of the symptoms related to these severe skin reactions described in section 4.

Children

The safety and efficacy of rifaximin have not been established in children under 12 years of age.

  • In case of activated charcoal administration, Spiraxin should be taken at least 2 hours after that administration.
  • In case of liver failure, caution should be exercised when taking:
    • Warfarin (a medicine to prevent blood clotting)
    • Antiepileptics (medicines to treat epilepsy)
    • Antiarrhythmics (medicines to treat abnormal heart rhythm)

It is recommended to take additional contraceptive precautions if you are taking Spiraxin with oral contraceptives (see "Taking Spiraxin with other medicines"),

It is not known whether rifaximin is excreted in breast milk. Therefore, Spiraxin should not be used during breastfeeding.

This dose may be increased to 400 mg in adults every 8 hours, in those cases that, due to their complexity, may require a dose increase and always under medical criteria. It is recommended not to exceed 7 days of treatment.

No dose adjustment is necessary in patients with liver or kidney failure. Although no dose changes are expected, caution should be exercised in patients with impaired renal function.
