Atropine + Diphenoxylate + Furazolidone is a prescription oral medicine that may be used for the short‑term management of infectious diarrhoea in adults and adolescents. It combines diphenoxylate, which can slow bowel movements; atropine, which may reduce spasms; and furazolidone, which can act against bacteria and protozoa. By addressing both symptoms and possible infectious causes, Atropine + Diphenoxylate + Furazolidone may provide relief when used under medical supervision along with proper fluid and electrolyte replacement.

Atropine + Diphenoxylate + Furazolidone is a prescription oral medication that combines three active ingredients (Atropine, Diphenoxylate, and Furazolidone) to provide both symptomatic relief and antimicrobial treatment for infectious diarrhoea in adults and adolescents aged 13 years and older.

Diphenoxylate is a synthetic opioid derivative that slows intestinal motility. By reducing the speed of bowel movements, it helps control the frequency of loose stools. Atropine, present in very small amounts, reduces intestinal spasms and limits secretions. Together, these two agents provide effective relief from the discomfort and urgency associated with diarrhoea. Furazolidone is an antimicrobial agent with activity against a range of bacteria and protozoa that commonly cause gastrointestinal infections. By targeting the root cause of infectious diarrhoea, it helps eliminate pathogens and supports recovery.

This combination makes Atropine + Diphenoxylate + Furazolidone unique because it addresses both the symptom (frequent, loose stools) and the underlying cause (infection). It is particularly useful in cases of acute infectious diarrhoea, including traveller’s diarrhoea, where rapid relief and pathogen control are both needed.

Atropine + Diphenoxylate + Furazolidone should always be used alongside adequate fluid and electrolyte replacement therapy to prevent dehydration, which is a common complication of diarrhoea. Treatment should be taken exactly as prescribed by a healthcare provider, since improper use may lead to side effects or reduced effectiveness.

Possible side effects include drowsiness, dizziness, dry mouth, nausea, and mild abdominal discomfort. More serious reactions, such as allergic responses, severe gastrointestinal symptoms, or hypertensive reactions (due to Furazolidone’s mild MAO‑inhibiting properties), should be reported to a doctor immediately.

Atropine + Diphenoxylate + Furazolidone is typically indicated by a doctor for:

Acute Diarrhoea

To reduce the frequency and urgency of bowel movements during sudden-onset diarrhoea.

Bacterial Enteritis

To treat inflammation of the intestines caused by susceptible bacterial strains.

Traveller's Diarrhoea

To manage digestive infections acquired through contaminated food or water.

Giardiasis

To eliminate protozoal infections that cause persistent gastrointestinal upset.

Intestinal Spasms

To ease the painful cramping and "colic" associated with diarrhoeal diseases.

Atropine + Diphenoxylate + Furazolidone provides benefits such as:

• Provides a simplified way of combining three distinct therapeutic actions: slowing bowel movements (Diphenoxylate), reducing spasms and secretions (Atropine), and antimicrobial activity against bacteria and protozoa (Furazolidone).

• May help reduce the frequency and urgency of loose stools, improving patient comfort during acute infectious diarrhoea.

• Can act directly on infectious causes of diarrhoea, unlike medicines that only control symptoms.

• Can reduce fluid loss when paired with oral rehydration therapy, lowering the risk of dehydration.

• May improve overall quality of life during episodes of acute diarrhoea by easing abdominal discomfort and urgency.

• When used appropriately under medical supervision, Atropine + Diphenoxylate + Furazolidone can lower the risk of complications associated with prolonged or severe diarrhoea.

Atropine + Diphenoxylate + Furazolidone may cause side effects, although not everyone will experience them. Most reactions are mild and temporary, but some can be more severe and require medical attention.

Common side effects of Atropine + Diphenoxylate + Furazolidone may include

• Dryness of the mouth, nose, or throat

• Drowsiness or dizziness

• Nausea or vomiting

• Abdominal bloating or discomfort

• Darkened or brownish urine (a harmless effect of furazolidone)

Uncommon side effects of Atropine + Diphenoxylate + Furazolidone may include

• Blurred vision or dilated pupils

• Headache

• Loss of appetite

• Restlessness or confusion

• Fast heartbeat (tachycardia)

Serious side effects that may require immediate medical attention include

• Severe Allergic Reaction: Difficulty breathing, swelling of the face or throat, or widespread hives.

• Toxic Megacolon: Extreme abdominal distension and pain, particularly in patients with inflammatory bowel disease.

• Hypertensive Crisis: Severe headache, palpitations, or chest pain (risk associated with furazolidone and tyramine foods).

• Respiratory Depression: Slow, shallow, or laboured breathing.

• Take Atropine + Diphenoxylate + Furazolidone exactly as prescribed by your doctor or product label.

• Swallow the medicine with water. It may be taken with or without food.

• Always drink plenty of fluids and use oral rehydration solutions to prevent dehydration.

• Use only for short‑term treatment of acute infectious diarrhoea. Stop once stools become firm or formed, unless advised otherwise.

• Do not drink alcohol during treatment and for at least 4 days after your last dose.

• Avoid foods rich in tyramine (aged cheese, cured meats, fermented products) to prevent blood pressure spikes.

• Do not use if you have bloody diarrhoea, a high fever, or in infants/very young children. Older children should only use it under strict medical supervision.

• Inform your doctor if you have G6PD deficiency, as Furazolidone can cause red blood cell breakdown.

Atropine + Diphenoxylate + Furazolidone combines three active ingredients that act through complementary pathways to stabilise the digestive system:

• Diphenoxylate: Acts on the opioid receptors in the intestinal muscles to inhibit long-range contractions, thereby slowing the passage of stool.

• Atropine: An anticholinergic that blocks acetylcholine receptors, which decreases intestinal secretions and relaxes the smooth muscle to stop cramping.

• Furazolidone: Interferes with the DNA and enzyme systems of bacteria and protozoa, preventing their growth and causing cell death. It also has a mild monoamine oxidase inhibitory (MAOI) effect.

• Stay Hydrated: This medicine stops the diarrhoea, but you must still drink oral rehydration salts (ORS) to replace lost electrolytes.

• Dietary Awareness: While taking this, avoid aged cheeses, fermented soy products, and red wine to prevent dangerous blood pressure spikes.

• Dry Mouth: If you experience dry mouth, sip small amounts of water or suck on sugar-free lozenges.

Store at room temperature in a cool, dry place away from direct sunlight. Keep the container tightly closed. This medication is particularly dangerous if accidentally ingested by children; keep it securely out of their reach.

• Tyramine-Rich Foods (SEVERE): Furazolidone's MAOI effect makes aged cheeses, cured meats, and fermented foods dangerous, potentially causing high blood pressure.

• Alcohol (SEVERE): Consumption of alcohol within 4 days of taking this medicine can cause a severe "disulfiram-like" reaction (vomiting/tachycardia).

• Bland Diet (RECOMMENDED): Sticking to the BRAT diet (Bananas, Rice, Applesauce, Toast) during treatment helps settle the stomach.

• MAOIs and Antidepressants (SEVERE): Do not combine with other MAO inhibitors or certain SSRIs, as this can lead to life-threatening blood pressure or serotonin issues.

• Sedatives and Opioids (MODERATE): Diphenoxylate can increase the sedative effects of other central nervous system depressants.

• Blood Pressure Meds (CAUTION): Furazolidone may enhance the effect of medications used to lower blood pressure.

• Amantadine/Antihistamines (CAUTION): These can increase the "drying" side effects of the atropine component.

• Glaucoma (CAUTION): Atropine can increase intraocular pressure, potentially worsening narrow-angle glaucoma.

• G6PD Deficiency (SEVERE): Furazolidone may cause hemolytic anaemia (breakdown of red blood cells) in individuals with this deficiency.

• Ulcerative Colitis (CAUTION): Antidiarrhoeals can increase the risk of toxic megacolon in patients with active colitis.

• Prostate Enlargement (CAUTION): Atropine may cause urinary retention in men with an enlarged prostate.

• An overdose of Atropine + Diphenoxylate + Furazolidone is a medical emergency. Symptoms can appear up to 30 hours after ingestion due to delayed gastric emptying caused by Diphenoxylate.

• Signs of overdose include: slow or laboured breathing, extreme drowsiness, confusion, slurred speech, weak rapid pulse, blurred vision, flushing, dry skin, very high fever, seizure, loss of consciousness, or coma.

• An overdose can be fatal, particularly in children. If you suspect an overdose, call a doctor or emergency services immediately. Do not wait for symptoms to appear.

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose. Do not take extra medicine to make up for a missed dose.
