It’s important not to continue Rifakem (Rifaximin-400mg) beyond the prescribed duration without consulting the prescribing doctor, especially since your sister’s vomiting, stomach pain, and constipation persist despite the medication.

⚠️ What This Means Now

• Rifakem is mainly used for certain bacterial infections causing diarrhea, but ongoing vomiting and new symptoms like constipation suggest the infection may not be fully treated or there could be another cause.
• Since symptoms have lasted a week and include stomach pain and constipation, this warrants evaluation by a gastroenterologist or pediatrician promptly.

🩺 Next Steps

• Stop Rifakem only if advised by the doctor; do not self-discontinue or extend beyond their guidance.
• Seek medical review urgently to reassess diagnosis and treatment. Additional investigations or a different treatment may be needed.
• Monitor for worsening symptoms such as severe abdominal pain, persistent vomiting preventing hydration, high fever, blood in vomit or stool, or signs of dehydration, which require immediate medical attention.

Your sister should be seen by her doctor or a gastroenterologist soon to ensure proper management and avoid complications.
