Help relieve symptoms associated with intestinal infections
Improve stool consistency during digestive disturbances
Help reduce irritation in the stomach and intestinal lining

Follow these instructions while taking Bistas Tablet 8:

Take the tablet exactly as prescribed by your doctor.
Swallow the tablet whole with a glass of water.
Do not crush, chew, or break the tablet unless advised otherwise.
Maintain adequate fluid intake during treatment.
Take the medicine for the duration advised by your doctor.

Bistas Tablet 8 is taken orally.

Bistas Tablet 8 may cause side effects such as:

Darkening of stools
Nausea
Constipation
Abdominal discomfort
Blackening of the tongue

Management Of Side Effects:

Most side effects are temporary and generally improve as your body adjusts to the medicine. However, if you experience any serious side effects or worsening of any symptoms, consult your doctor.

Here are a few tips that may help:

Constipation: Drink adequate fluids and include fibre-rich foods in your diet if advised by your doctor.
Nausea: Taking the medicine after light meals may help reduce this side effect.

Bistas Tablet 8 contains the following active ingredient:

Bismuth trioxide (120 mg): It works by forming a protective coating over irritated areas of the stomach and intestinal lining, helping reduce irritation associated with digestive disturbances. It may help reduce diarrhoeal symptoms and support improvement in stool consistency.

Pregnancy

Bistas Tablet 8 should be used during pregnancy only if advised by your doctor. Limited information is available regarding its safety during pregnancy.

Breastfeeding

Consult your doctor before taking Bistas Tablet 8 while breastfeeding. Small amounts of bismuth-containing compounds may pass into breast milk.

Alcohol

Avoid alcohol while taking this medicine, as it may worsen stomach irritation and digestive discomfort in some individuals.

Liver

Inform your doctor if you have liver disease before taking Bistas Tablet 8. Careful monitoring may be required in patients with severe liver problems.

Kidney

Inform your doctor if you have kidney problems before taking Bistas Tablet 8. Colloidal bismuth subcitrate-containing medicines may accumulate in patients with severe kidney impairment and increase the risk of side effects.

Use In Driving And Operating Machinery

Bistas Tablet 8 does not usually affect the ability to drive or operate machinery. However, avoid such activities if you feel unwell during treatment.

Allergy

Do not take Bistas Tablet 8 if you are allergic to colloidal bismuth subcitrate-containing medicines or any ingredients of this medicine. Seek immediate medical attention if you develop rash, swelling, itching, or breathing difficulty.

Children

Bistas Tablet 8 should be used in children only if prescribed by a doctor. Antidiarrhoeal medicines should be used cautiously in paediatric patients.

Older Patients

Older adults may be more sensitive to dehydration and constipation associated with diarrhoeal illness. Medical supervision may be required during treatment.

Drug-Drug Interactions

Bistas Tablet 8 may interact with the following medicines:

Antihypertensive medicines (e.g., amlodipine, atenolol): Severe diarrhoea may affect fluid balance in patients taking antihypertensive medicines. Your doctor may monitor blood pressure and hydration status during treatment.
Antidiabetic medicines (e.g., insulin, metformin): Diarrhoea and reduced food intake may affect blood sugar control in patients taking antidiabetic medicines. Your doctor may advise regular blood glucose monitoring if needed.
Antitubercular medicines (e.g., rifampicin, isoniazid): Some antitubercular medicines may worsen digestive symptoms in some individuals when taken together. Your doctor may monitor digestive symptoms during treatment.
Antiepileptic medicines (e.g., phenytoin, carbamazepine): Severe diarrhoea may affect the absorption of some antiepileptic medicines, potentially reducing their effectiveness. Your doctor may monitor treatment response if required.
Tetracycline antibiotics (e.g., doxycycline, tetracycline): Colloidal bismuth subcitrate-containing medicines may reduce the absorption and effectiveness of tetracycline antibiotics. Your doctor may advise maintaining a gap between these medicines during treatment.

Drug-Disease Interactions

Bistas Tablet 8 should be used with caution if you have:

Severe constipation or intestinal blockage: Taking this medicine may worsen constipation or bowel obstruction in patients with existing intestinal problems. Your doctor may advise avoiding this medicine in such conditions.
Stomach bleeding or ulcers: This medicine may make it difficult to identify stomach bleeding because it can cause temporary darkening of stools. Your doctor may monitor symptoms carefully during treatment.
Severe dehydration: Diarrhoea may already cause fluid and electrolyte loss, and patients with dehydration may require fluid replacement and close monitoring during treatment.

Daily Dose

The daily dose of Bistas Tablet 8 should be taken as prescribed by your doctor. The dosage may vary depending on the severity of symptoms, response to treatment, and overall health condition. Do not exceed the prescribed dose without consulting your doctor.

Over Dose

Taking more than the prescribed amount of Bistas Tablet 8 may increase the risk of nausea, vomiting, severe constipation, confusion, stomach discomfort, or nervous system-related side effects. Seek immediate medical attention if overdose is suspected.

Missed Dose

If you miss a dose of Bistas Tablet 8, take it as soon as you remember. If it is nearly time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not take two doses together to compensate for the missed dose.

Store Bistas Tablet 8 below 30°C.
Keep the medicine in a dry place away from moisture and heat.
Protect from direct sunlight.
Keep out of reach of children.
Do not use after the expiry date mentioned on the pack.

Drink adequate fluids such as water, ORS, soups, and clear liquids to help prevent dehydration associated with diarrhoea.
Consume light and easily digestible foods such as rice, bananas, toast, curd, and boiled potatoes until digestive symptoms improve.
Avoid spicy, oily, or very heavy meals, as these may worsen stomach irritation and loose stools.
Maintain proper hand hygiene and safe food practices to help reduce the risk of gastrointestinal infections and food-borne illness.
Avoid consuming contaminated water or unhygienic food during recovery from digestive disturbances.
