Phenotil Tablet

Phenotil Tablet contains Diphenoxylate and Atropine. It is used for short-term management of diarrhoea when supportive measures such as diet and fluids alone are not sufficient, and only under medical supervision.

Diphenoxylate works by slowing the movement of the intestines. This reduces how quickly stool passes through the gut, allowing more time for water and salts to be absorbed. As a result, stool frequency and looseness are reduced. Atropine is included in a very small amount to support the safe use of the medicine. It also contributes to reducing intestinal movement through its anticholinergic action.

Because this medicine slows intestinal movement, it is not suitable for all types of diarrhoea. In some infections, especially those with fever or blood in the stool, slowing the gut may worsen symptoms by delaying the clearance of the underlying cause. For this reason, it should only be used after proper medical assessment.

The medicine is generally used for a limited duration under supervision, along with attention to hydration and underlying causes of diarrhoea. Common side effects may include dry mouth, dizziness, drowsiness, constipation, or blurred vision.

Phenotil Tablet may be indicated by your doctor for:

Acute Diarrhea

Short-term management of sudden, severe diarrhea.

Chronic Diarrhea

Management of persistent diarrhea associated with conditions like inflammatory bowel disease (IBD), as an adjunct to other therapies.

Post-Surgical Management

Reducing the volume of discharge from ileostomies or colostomies.

Phenotil Tablet may provide benefits such as:

• Reduces Urgency: Helps manage the immediate and distressing need to visit the bathroom.

• Improved Stool Consistency: Promotes better water reabsorption, leading to firmer stools.

• Frequency Control: Decreases the total number of bowel movements throughout the day.

• Stabilizes Gut Motility: Calms hyperactive intestinal muscles.

• Abdominal Comfort: May help reduce cramping often associated with rapid intestinal transit.

Common side effects of Phenotil Tablet may include

• Drowsiness or dizziness

• Dry mouth, nose, or throat

• Nausea or vomiting

• Loss of appetite

• Headache

Uncommon side effects of Phenotil Tablet may include

• Blurred vision

• Rapid heartbeat (tachycardia)

• Restlessness or euphoria

• Confusion or hallucinations

Serious side effects (rare) that require immediate medical attention

• Severe Abdominal Bloating: Signs of toxic megacolon (extremely swollen abdomen).

• Paralytic Ileus: Complete lack of bowel movement accompanied by severe pain.

• Severe Allergic Reaction: Rash, swelling of the face/lips, or difficulty breathing.

• Signs of Dehydration: Extreme thirst, very dark urine, or decreased urination.

Always consult your doctor if you notice any unusual symptoms while taking Phenotil Tablet.

• Take Phenotil Tablet exactly as prescribed. Do not exceed the recommended dose.

• It is typically taken four times a day until the diarrhea is controlled.

• Once the diarrhea improves, your doctor may reduce the dose.

• Drink plenty of fluids (water, oral rehydration solutions) to prevent dehydration while you have diarrhea.

• If you do not see any improvement after 48 hours of treatment, contact your doctor.

• Wash Hands: Always practice good hygiene to prevent the spread of infection.

Diphenoxylate acts on opioid receptors within the intestinal muscles to inhibit the release of acetylcholine and prostaglandins. This slows down intestinal motility and increases the transit time of the intestinal contents. Atropine is an anticholinergic agent; in this combination, its sub-therapeutic dose blocks certain nerve signals to the salivary glands and heart only if taken in excess, acting as a pharmacological "safety lock" against overdose.

• Stay Hydrated: Diarrhea causes significant loss of water and salts. Use an oral rehydration solution alongside this medicine.

• Dietary Adjustments: While treating diarrhea, try eating bland foods like bananas, rice, or toast (the BRAT diet) and avoid spicy or fatty foods.

• Monitor for Fever: If your diarrhea is accompanied by a high fever or bloody stools, do not use this medicine and call your doctor immediately.

• Check for "Rebound": Once your bowel movements become normal, stop taking the medication as directed by your doctor to avoid constipation.

• Store at room temperature away from light and moisture.

• Keep the bottle tightly closed.

• Strictly keep out of reach of children.

• Do not use past the expiry date.

• General Diet (Safe): No specific foods interact with the drug, but avoiding dairy and caffeine may help the diarrhea resolve faster.

• MAO Inhibitors (Unsafe): Using this with MAOIs (e.g., phenelzine) may lead to a severe hypertensive crisis (very high blood pressure).

• CNS Depressants (Caution): Sleep aids, anxiety medications, or other opioids can worsen drowsiness and slow down breathing.

• Anticholinergics (Caution): Other medicines that cause dry mouth or blurred vision can have an additive effect.

• Infectious Diarrhea (Caution): Do not use if the diarrhea is caused by organisms that penetrate the intestinal mucosa (like Salmonella or Shigella).

• Ulcerative Colitis (Caution): May increase the risk of a serious complication called toxic megacolon.

• Glaucoma (Caution): The atropine component may increase pressure in the eye.

• Down Syndrome (Caution): Patients with Down Syndrome may be more sensitive to the effects of atropine.

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed one. Do not take two doses at once to make up for a missed application.
