Myritz 400mg Tablet 10s

Myritz 400mg Tablet 10s is an antibiotic containing Rifaximin, primarily used to treat certain bacterial infections in the intestines. It works locally in the gut to reduce harmful bacteria, helping to manage conditions such as traveller’s diarrhoea, irritable bowel syndrome with diarrhoea (IBS-D), and hepatic encephalopathy. Rifaximin is minimally absorbed into the bloodstream, which allows it to act directly in the intestines while limiting systemic side effects. It is typically prescribed for adults and should be used exactly as directed by a healthcare professional to ensure effectiveness and reduce the risk of antibiotic resistance.

Myritz 400mg Tablet 10s contains Rifaximin, a broad-spectrum antibiotic that works directly in the intestines to combat harmful bacteria. Unlike many other antibiotics, rifaximin is minimally absorbed into the bloodstream, allowing it to act locally in the gut while reducing the risk of systemic side effects.

This medicine is commonly prescribed for several gastrointestinal conditions. It is effective in treating traveller’s diarrhoea caused by certain strains of bacteria. It is also used in adults with Irritable Bowel Syndrome with diarrhoea (IBS-D) to help reduce abdominal discomfort and frequent bowel movements. Additionally, Myritz 400mg Tablet 10s is used in patients with liver disease to manage hepatic encephalopathy by lowering the levels of ammonia-producing bacteria in the intestines, which can help prevent complications.

Rifaximin works by inhibiting bacterial RNA synthesis, preventing the growth and replication of harmful bacteria in the gut. By restoring a healthier balance of intestinal bacteria, it helps relieve symptoms, reduce inflammation, and lower the risk of recurrent infections.

It is important to take Myritz 400mg Tablet 10s exactly as prescribed and to complete the full course, even if symptoms improve. Following your healthcare provider’s guidance on diet, lifestyle, and other medications is essential to ensure the medicine works effectively and to prevent antibiotic resistance.

Myritz 400mg Tablet 10s (Rifaximin) is indicated for several specific gastrointestinal and hepatic conditions:

Hepatic Encephalopathy (HE):

To reduce the risk of recurrence of overt brain dysfunction in adults with chronic liver disease.

Irritable Bowel Syndrome with Diarrhoea (IBS-D):

To treat the primary symptoms of bloating, abdominal pain, and loose stools.

Traveller’s Diarrhoea:

Used for diarrhoea caused by non-invasive strains of E. coli in adults and children.

Small Intestinal Bacterial Overgrowth (SIBO):

Used to clear excessive bacteria from the small bowel that cause chronic bloating.

Diverticular Disease:

Sometimes used to reduce inflammation and prevent flare-ups of chronic diverticulosis.

Localised Action:

It acts only in the gut, meaning it does not cause yeast infections or other systemic issues seen with other antibiotics.

Low Resistance Risk:

Because it is not used for systemic infections (like pneumonia), the risk of developing widespread bacterial resistance is very low.

Liver Protection:

It is a life-changing therapy for cirrhosis patients, allowing them to maintain mental clarity and stay out of the hospital.

Rapid Symptom Relief:

Patients with IBS-D often experience a significant reduction in bloating and urgency within a two-week course.

Eubiotic Effect:

It primarily targets harmful bacteria while appearing to spare many beneficial species, unlike broad-spectrum drugs.

Despite being very safe, some patients may experience mild gastrointestinal or general reactions.

Common Side Effects:

• Nausea: Mild stomach upset after taking the dose.
• Dizziness: Some patients feel slight lightheadedness or fatigue.
• Flatulence/Bloating: Paradoxically, as bacteria die off, gas may temporarily increase during early treatment.
• Peripheral Oedema: Mild swelling in the hands or feet, more commonly seen in patients with existing liver disease.

Serious Side Effects (Seek medical attention immediately):

• C. diff Diarrhoea: While rare, any antibiotic can trigger Clostridioides difficile infection, causing severe watery or bloody diarrhoea.
• Severe Allergic Reaction: Hives, swelling of the face, or difficulty breathing.
• Severe Abdominal Pain: Intense cramping that does not go away after the first few days of treatment.

• Dosing Schedule: For HE, the dose is usually one tablet twice daily. For IBS-D, it is often one tablet three times daily for 14 days.
• Food Intake: Can be taken with or without food as absorption is not the goal.
• Completion of Course: If treating IBS-D or SIBO, you must finish the entire 14-day course even if you feel better within the first few days.
• Swallowing: Swallow the tablet whole with water; do not crush or chew it to ensure it reaches the intestines intact.

• Stay Consistent: For liver health, taking Rifaximin every day is vital to prevent toxins from reaching the brain.
• Watch for "Die-off": In SIBO treatment, you may feel slightly worse for the first 48 hours as bacteria die; this is often a sign of efficacy.
• Probiotic Timing: If taking probiotics, wait at least 2 hours after your Rifaximin dose to protect the beneficial bacteria.
• Report Diarrhoea: If you develop severe, watery diarrhoea after finishing the course, notify your doctor immediately.

• Store at room temperature away from excessive heat and moisture.
• Keep the tablets in their original packaging until use to maintain stability.
• Keep out of reach of children.

1. P-glycoprotein Inhibitors: Drugs like Cyclosporine may slightly increase the amount of Rifaximin absorbed into the blood.
2. Warfarin: Any antibiotic can occasionally change how blood thinners work by altering the gut flora that produces Vitamin K.
3. Oral Contraceptives: Because absorption is so low, it does not usually interfere with birth control pills.
