Both Atropine and Diphenoxylate work by reducing the movement of the muscles in the intestines. This effect helps to:
- Slow down bowel movements: The intestines contract less frequently, allowing stool to stay in the intestines longer, which provides more time for fluid and nutrients to be absorbed.
- Reduce fluid loss: By slowing down intestinal activity, less water is lost in the stool, helping to prevent dehydration, which is a serious risk with severe diarrhea.
- Control cramping: Since the medications reduce the spasm-like movements in the intestines, they can also help reduce abdominal cramping, which is a common symptom of diarrhea.
Like all medications, Atropine and Diphenoxylate may cause side effects. The most common side effects include:
- Drowsiness: Both Diphenoxylate and Atropine can cause drowsiness or dizziness. It’s important not to drive or operate heavy machinery while taking this medication, especially at higher doses.
- Dry Mouth: Atropine can cause dry mouth, which may make it difficult to swallow or speak. This side effect usually goes away once the medication is stopped.
- Constipation: While the medication is intended to reduce diarrhea, in some cases, it may cause constipation. If constipation becomes a problem, contact your doctor.
- Blurred Vision: Atropine can affect vision, causing temporary blurred vision or sensitivity to light.
- Nausea and Vomiting: Some people may experience nausea or vomiting, especially when they first start taking the medication.
- Difficulty Urinating: Both Atropine and Diphenoxylate can cause urinary retention, making it harder to urinate. If you experience this, inform your doctor.
- Increased Heart Rate: Atropine can cause an increase in heart rate or palpitations in some people.
- Allergic Reactions: Although rare, some people may experience allergic reactions, including rash, itching, or difficulty breathing. Seek medical attention if you have signs of an allergic reaction.
Before using Atropine and Diphenoxylate, it is important to consider the following precautions:
- Not for Certain Conditions: This medication should not be used in individuals with certain conditions, such as glaucoma, liver disease, or intestinal obstruction. It is also not recommended for individuals with severe dehydration.
- Pregnancy and Breastfeeding: If you are pregnant or breastfeeding, consult your doctor before using this medication. The safety of Atropine and Diphenoxylate during pregnancy and breastfeeding is not fully established.
- Use with Caution in Older Adults: Older adults may be more sensitive to the side effects of this medication, such as dizziness, confusion, and urinary retention.
- Kidney or Liver Problems: If you have kidney or liver issues, you may need a dose adjustment or a different medication, as Diphenoxylate and Atropine can affect these organs.
- Avoid Alcohol: Alcohol can increase the sedative effects of Diphenoxylate and Atropine, leading to severe drowsiness, dizziness, or even respiratory depression.
- Drug Interactions: Tell your doctor about all the medications you are taking, including prescription drugs, over-the-counter medications, and herbal supplements. Diphenoxylate may interact with other medications that depress the central nervous system, such as benzodiazepines, antihistamines, or opioid medications.
CNS Depressants: Combining with alcohol, benzodiazepines, or other sedatives can enhance drowsiness and sedation, increasing the risk of severe drowsiness or respiratory issues.
Opioid Medications: Using with other opioids (like morphine) may increase the risk of overdose, leading to slow breathing or low blood pressure.
Anticholinergic Drugs: Combining with other anticholinergics (e.g., antihistamines) can worsen side effects like dry mouth, blurred vision, or constipation.
Other Diarrhea Medications: Using with other anti-diarrheals, like loperamide, can lead to constipation or bowel obstruction. Always consult your doctor.
The typical dosage of Atropine and Diphenoxylate for treating severe diarrhea in adults is:
- 2.5 mg of Diphenoxylate and 0.025 mg of Atropine taken 2 to 3 times per day as needed.
- Children: For children, the dosage is determined based on their age and weight, and a pediatrician should guide it.
Always follow the instructions provided by your doctor or pharmacist.
Atropine and Diphenoxylate are prescription medications, meaning they must be prescribed by a healthcare provider. It is essential to consult your doctor to determine if this combination is right for you, especially if you have underlying health conditions or are taking other medications.
